Processing(Bush + Obama) = BushBama

Saturday, May 26th, 2012


Last night I was working on creating some image processing routines with Processing. My focus was on using convolution matrices to implement a number of effects. With respect to image processing, a convolution matrix is useful for a variety of effects, like edge detection, blurring, sharpening, and embossing.

I had also written some methods/routines/functions (take your pick) that added or subtracted fixed color values from every pixel in an image. I had also written image AND and OR routines so that I could perform either a logical AND or a logical OR between every pixel in the source photograph and every pixel in the image created by one of the other filter effects I had written.

This got me to thinking. I thought it might be cute to see what happened if I were to ‘add’ two images together. I thought adding two faces together would be nice so I went to Google Image Search and searched on the keyword ‘portrait’. The first photo that showed up in my search was a White House portrait of Barack Obama. It instantly occurred to me that there was only one suitable matching photograph to use for the addition operation: an official White House portrait of George Bush.

I had to use Photoshop to insure that the two faces lined up reasonably well and that the images were of the same dimensions (I didn’t feel like writing a scaling function right then). I then ran the two portraits through my program and obtained the results shown above. Note that this is a slightly scaled down version of the original as the original was too large to display in this space.

Question: realistically – will I ever use this image addition routine to do ‘real’ work? I seriously doubt it. Call me a geek but I just happen to enjoy writing code. Anyway it’s time to put the keyboard aside and head out to the Schaumburg Prairie Arts Festival. Hopefully the rain will stay away.

Ad Astra, Jim

From Capricon to Floral Photography

Tuesday, February 14th, 2012

The Flyers of Fomalhaut b Digital Art Painting
The Flyers of Fomalhaut b Digital Painting

Part 1: The Capricon Science Fiction Convention

This year Capricon was a short affair for me. While the con ran Thursday thru Sunday, I only attended Friday and Saturday and then only until 6:30pm as I had made plans to attend the opening of a photo exhibition at the Prairie Arts Center in Schaumburg. And because I was not returning on Sunday I did not participate in the art show. On Saturday I did make sure to go through the art show and was happy to see work exhibited by a couple of my friends. What I found disturbing though was the fairly large number of empty display bays in the show. In my experience the Capricon Art Show generally has little, if any, unused space. Unfortunately I had to leave before the start of the art auction so have no idea how well that went.

With respect to programming, my only job Friday was as a panelist on Pluto Is Still a Planet in Illinois with Bill Higgins (Fermilab physicist) moderating and copanelists Brother Guy Consolmagno (Vatican Observatory) and Steven Silver (Capricon Fan Guest of Honor). This was a really good panel given that Brother Guy was a part of the IAU meeting at which the Pluto vote was made and Steven was a friend of Clyde Tombaugh, the man who discovered Pluto. If you were at Capricon and missed this panel – it was definitely your loss.

I arrived back at the con Saturday morning shortly before I was scheduled to give my presentation The Art of the Exploration of Space. I especially liked that I had 75 minutes to speak as this allowed me to go at a leisurely pace and engage in conversation with the audience as I went along. This was immediately followed by my moderating a panel at the opposite end of the convention on Goodbye, Space Shuttle. My copanelists were Henry Spencer, Chris Gerrib, and Kent Nebergall. Kent had the misfortune of being in the audience of my space art presentation whereupon I drafted him for the Space Shuttle panel as I knew that he would have valuable insights to contribute.

I next attended The Coming War on General Purpose Computation presentation by Cory Doctorow, the author guest of honor. It was a fascinating presentation. While I agreed with Doctorow on SOPA and other aspects of attempts to stamp out the theft of intellectual property, I came away dissatisfied that he offered no remedy for the authors, artists, and musicians who are having their work stolen. I was also somewhat surprised by his stance towards Facebook in that he seemed to believe that people should not be given the choice of sharing their information on social networks. I viewed this as being inconsistent with what I would characterize as a free and open internet perspective.

The last panel I attended was the most boring panel I have ever attended at any science fiction convention. Now with a title like Civil Disobedience: Occupy Wall Street and the Tea Party Movement you would expect there to be an invigorating debate between the panelists and between the panelists and the audience. However, this panel was run by the brown shirts. No audience participation was allowed. There was a short period at the end where 5 people were identified and allowed to ask one question each with no follow up or commentary by the questioners permitted. In short, this panel was a total waste of time for the audience.

In summary, I’d say that the best things about Capricon were:

  • The accidental meetings
  • The conversations in the halls
  • The food in the green room
  • Prowling the Dealers Room
  • Checking out the art show
  • How well my The Art of the Exploration of Space presentation went and the ensuing conversations
  • Being on the Pluto panel with Brother Guy Consolmagno, Bill, and Steven
  • Friday lunch in the Green Room with Brother Guy, Bill Higgins, and Henry Spencer
  • Drafting Kent Nebergall to serve on the Space Shuttle panel.

Only one more year until Capricon 33!

Part 2: The Photography Exhibition at the Prairie Art Center, Schaumburg IL

Departing Capricon, I swung by home to grab a bite to eat and then headed over to the Prairie Art Center to take in a photography exhibition that was opening that night in the Herb Aigner Gallery. Titled Flowers in Our Soul, the show is devoted to artistic photographs of flowers and consists of 27 separate works. The photographers that I identified as having work on display in the show are Maria Aiello, Mary Angelini, Debbie Beller, Cindy Brumm, Susan Couch, Randee Lawrence, and Karie Strangeway. I had the opportunity to speak with several of them about their work. I was also curious to learn whether they printed their own work or used an outside service. If you would like to see the show, it runs through the end of February. See Prairie Center for the Arts, Schaumburg IL.

The Illustration

To illustrate this post I decided to use a piece of science fiction art that I just added to my web site. Titled The Flyers of Fomalhaut b, it is an imagining of what the life of exoplanet Fomalhaut b is like (note: not only is there no evidence of life on this planet, there is some question as to whether or not the planet even exists). Fomalhaut b appears to be a Jupiter-like planet that is about three times more massive than Jupiter and which orbits the star Fomalhaut once every 872 years. By comparison Pluto takes 248 years to complete an orbit of the Sun.

For more about this digital painting, see The Flyers of Fomalhaut b.

Until next time, Ad Astra, Jim

Disappointment with Chicago Artists Coalition

Wednesday, May 19th, 2010

Chicago Artists Coalition
Screen shot of Chicago Artists Coalition email

Imagine my surprise and disappointment when I opened an email blast from the Chicago Artists Coalition (CAC) and discovered that it contained three photographs taken from my web site. The three photos are part of a set of seven that I had taken at the Chicago Art Open Preview and Benefit Party at River East Art Center on April 20 and used to illustrate an article on my web site – Chicago Art Open Preview and Benefit Party at River East Art Center. For a view of the article in question, see this CAC email screen shot. Of the four photos shown in the screen shot, the group photo in the upper left (deliberately blurred) is not mine while the other three photos are.

Not only was I not asked if the photographs could be used but I was not given credit either. One would think that an organization representing artists would know better than to use copyrighted material without first getting permission. As a rule I’m pretty open about allowing non-profits to use my art at no cost. In fact if I had been asked by the Chicago Artists Coalition, I would have gladly said yes to letting them use the photographs. I used to be a member of this organization but did not renew as their dues continued to increase and their charge to artist members to have art shown on the CAC web site is far too expensive.

The Value of Metadata

As a rule, before posting any image to the Internet, I try to make sure that I have filled in the authorship-related fields in the image’s metadata. This consists of the Title, Author, Author Title, Description Writer, Description (if any), Copyright Status, Copyright Notice, and Copyright URL. In the case of the photographs in question, I did fill in the metadata fields. Saving the images from the CAC email to my hard drive, I opened them in Photoshop and looked at the metadata. Yep – my copyright notice was still present. (See Photoshop Metadata Illustration)

Of course there is nothing to stop someone from either removing or altering the contents of the metadata fields. For an informative article on this subject, see Why Photoshop doesn’t provide secure metadata

Watermarking Images

In the case of these particular photographs, because of their relatively small size (430 by 322) I did not bother to watermark the images. Typically I will place a textual statement on the image that is of the following format:
Picture Title – Copyright Symbol – Year – Jim Plaxco – www.artsnova.com

This watermark is semi-transparent with placement depending on the size of the image. For smaller images I locate the watermark along the bottom margin. For larger images I shift the watermark up so that it is more prominent.

Finding Your Images

A relatively new tool available for publishers of images is a search engine called TinEye. TinEye is a reverse image search tool. The user either uploads an image to TinEye or provides the URL for an image on the net. TinEye then searches its database for images that resemble the image you’ve provided and returns their URL.

Unfortunately TinEye’s database is not comprehensive. In the past I found one of my images being used by a city government (from Brazil of all places) by typing into Google the filename of my original image. Can’t say that I have tried that approach lately. And of course there is always the google image search if you have lots of time on your hands.

In Conclusion

All I can say is to be vigilant and don’t be surprised if your art or photographs show up in unlikely places. It is worth noting that copyrights are far more likely to be violated by your average Joe than by your average corporation.

Photography at Navy Pier

Monday, April 19th, 2010

Windy schooner off Navy Pier
Windy schooner off Navy Pier

I took a photo excursion to Chicago’s Navy Pier last Thursday. It was a beautiful day for it and there were surprisingly few people there. I had brought along several model release forms just in case I happened upon a person that I wanted to photograph. However, no such opportunity presented itself.

One of my first stops was to take a ride on the ferris wheel. It cost $6.00 for the ride. The slow movement of the ferris wheel and partially open sides made possible some decent photos of the Chicago skyline. Unfortunately the backs and much of the sides were enclosed in plexiglass making photos at most angles impossible.

A while later the Windy, a 150 foot 4 masted schooner, came into dock which presented a nice photo op. I stopped by their ticket booth to get details. A one hour cruise was departing at 5:00pm which fit my schedule nicely. I came close to buying a ticket but one look to the east convinced me otherwise. It was a clear day and the Sun was about 35 degrees up in the sky. My principal purpose for taking the cruise was to get photos of the Chicago skyline from a different vantage point. However, given the clear sky and position of the Sun the pictures would not have turned out very good so I took a pass.

I continued to meander about taking photos, including a couple of the Chicago Harbor Lighthouse. By the time I started heading back in from the end of the pier, the Windy was starting her next cruise. It didn’t take long before she had her sails up. Fortunately I had brought along my telephoto lens so even though she was some distance away when she raised her sails, I was still able to get some decent shots. I used one of those shots to illustrate this post.

I also headed up to Olive Park to get some photographs of the John Hancock Building and points north. The sun position was pretty bad by then being low in the sky but still clearing all but the tallest buildings. However from where I was, the Sun lined up nicely with Huron Street and created a nice reflection in that sliver of Lake Michigan that lies between Olive Park and Lake Shore Drive.

Afterwards, I went to Charlie’s Ale House for dinner but got tired of waiting for someone to show up and seat me. A couple waitresses at the end of the bar looked up a few times before returning to chatting. Given how empty the place was they certainly couldn’t attribute their lack of service to being too busy. Obviously they rake in enough cash to not be concerned about the loss of a customer. I headed over to Carnelli’s Deli and grabbed a sandwich and drink instead. They took my order and made my sandwich in far less time than I had spent waiting at Charlie’s. Plus they were a good deal cheaper.

After eating I wondered around the Crystal Gardens. I took a few photographs of plants and the few flowers there. It was then time to head over to the IMAX theater to meet my friends and take in the Hubble 3D movie. For more about that part of my excursion, read Hubble 3D IMAX Movie.

By the time we got out of the restaurant, Navy Pier had been closed for over 90 minutes. I only got to take a few pictures before being directed by security to leave. In total I took over 150 photographs. In the days of film, I would have been far more judicious in the number of photographs I took. But this is the age of digital photography so I shoot away.

For me, the hardest part of photography these days is not taking the photograph. Rather, it is going through all the photographs afterwards: deciding which to delete and what to do with those I keep.

Schaumburg Prairie Arts Festival

Tuesday, May 26th, 2009

Schaumburg Prairie Arts Festival
Schaumburg Prairie Arts Festival

Saturday the kids and I attended the Schaumburg Prairie Arts Festival. It was beautiful weather for an outdoor fair. This is the 22nd year for this annual juried fine art festival. Over 150 artists and artisans participated in this year’s festival.

My prime motivation for attending was to see what other artists were up to. I confess to having largely ignored the artists specializing in sculpture, blown glass, jewelry, and pottery. My focus was on the work of the photographers and painters.

With respect to photography, one thing was evident: digital photography has become the dominant form of photography. Photographic works came in three basic forms. The first form was what I would call pure photography which consists of photographs with no apparent digital manipulation. The second category would be photographs in which various types of digital manipulation were evident – at least to someone experienced in such matters. The third category would be photographs that had been digitally altered to resemble paintings – a path most frequently taken by those working with Adobe Photoshop or Corel Painter.

I have no personal bias either for or against any of the three aforementioned categories. Rather, the only thing that matters to me is the end product. If someone can take a well composed photograph and skillfully manipulate it to create a convincing painting that is superior to the original photograph, then kudos to that photographer-artist. After all, the final image is what counts.

There were a number of traditional painters present at the art fair as well but for the most part their work, mostly executed on large canvases, was uninspiring. I found this to be particularly true of the abstract artists – though there were a few whose work was inspired.

Thinking back, one thing I don’t recall seeing were any purely digital paintings. Nor were there any artists whose work was the result of a 3D render. Being a fan of space art and astronomy, I was also disappointed to see no space art nor any astronomical art. The closest was a digital photograph of the Aurora Borealis.

Speaking of space art, the reason I am writing this entry so late (oops make that early) is because I spent Memorial Day and this evening (now yesterday) preparing artwork for the Space Art Show at the International Space Development Conference in Orlando Florida. I also created a 13 x 19 inch congratulatory space art card for Peter Kokh, the recipient of the National Space Society’s 2009 Gerard K. O’Neill Award For Space Settlement Advocacy. I do hope that Peter enjoys the card/artwork.

Until next time, Ad Astra

Hiking Moraine Hills State Park

Wednesday, April 22nd, 2009

Red-winged Blackbird
Red-winged Blackbird at Moraine Hills State Park, IL

The family and I spent Saturday hiking around Moraine Hills State Park, IL. This was our first visit to the park and we spent most of our time on the trails in the vicinity of Lake Defiance. It was an overcast day with light rain on and off but even so the trails had a fair share of hikers and bikers. This early in the year, the only thing green at the park is the grass.

Lake Defiance and the surrounding terrain were formed by the Wisconsin glacier which covered the area some 15,000 years ago. The park’s name, Moraine Hills, is a direct reference to the glacial process that created the terrain and lakes. About half the park’s 1700 acres is wetlands and lakes. Because of its diversity of habitats, Moraine Hills is well known for the abundance and variety of birds present. For example, the photograph of the Red-winged Blackbird used to illustrate this post.

For photographers interested in marshlands and birds, Moraine Hills State Park, located just east of McHenry IL, is an excellent destination. I don’t know why I didn’t visit before now. I do hope to have the opportunity to revisit the park in the coming month at which time I will concentrate on hiking the trails that run through the marshes. I must confess that on this trip I didn’t even take a dozen photographs. The sky was basically a flat gray and the only thing not brown was the grass. I expect that my next visit will be both greener and bluer.

The Photograph

The photograph used to illustrate this post was taken with a Nikon D50 fitted with a Nikon ED AF Nikkor 80-200mm lens. I brought the photograph into Photoshop and performed some digital manipulation on the picture leaving the blackbird untouched. I then shrunk and closely cropped the image to fit the web page.

American Photo Issue Review

Saturday, December 27th, 2008

Red rose
A red rose from Arizona

One of the things I did on Christmas Day, besides eating and opening presents with my family, was to read through the January/February 2009 issue of American Photo magazine. It is billed as a special issue as it features the results of their "Images of the Year Competition". The photo competition is divided into the categories commercial work, nature, personal work, portraiture, student work, and photojournalism.

The Commercial Work category led off with a photo of Madonna by Steven Meisel for the Green Issue of Vanity Fair. This was the photograph that won the category. I’ve got to admit that I have to agree with the judges – it is a good picture. In the Nature category a rather spectacular dirt-colored tornado against a cloudy blue sky by Jim Reed caught my eye. I thought that the most artistic was a black and white photo of a lions head with offsetting negative space by Boza Ivanovic. In the Personal Work category, my favorite is a nude by Mona Kuhn, which also happened to be the winning image for this category. Portraiture was for me the most disappointing category as it contained nothing I liked. The winning image was one of Barack Obama.

I liked the Student Work category the best. An architectural image with unusual perspective by Chang Kyun Kim was the winning image in this category. Edging out this image as my favorite was an abstract of I don’t know what created by Samantha Mintio of Singapore. It looks like a multiple exposure image and creates the impression of an abstract city that would adorn the cover of a science fiction novel. It’s too bad that the printed image was so small.

The final category was photojournalism. A choreographed wave of women all in yellow by Mike Blankenship (a distant relation possibly) was pretty cool but my favorite was a black and white industrial scene by Fred Conrad.

The book review that caught my eye was "Inside Out" which was a review of the 224 page book X-Ray: See Through the World Around You by Nick Veasey. Mr. Veasey makes use of really really big X-ray machines to image all sorts of things. The review features an image of a city bus complete with passengers and a Boeing 777. The article also provides a very brief overview of the techniques used to x-ray these objects. There is something about x-ray imagery that has always fascinated me and I look forward to getting my hands on a copy of this book.

The most useful article for me was "Closeup: Photo Books On Demand" which reviews ten print on demand services. The article identifies Lulu as one of the largest self-publishing companies with 1.8 million members and 600,000 titles published. My experience with Lulu was to publish a pair of calendars several years ago that featured my images of Mars. While the quality of the standard calendar was disappointing with respect to price, the quality of the premium calendar was quite good. I recently returned to Lulu to make a new calendar but was less than happy with their new work flow.

To help photographers with choosing a publisher for their projects, the review article includes for each company a single comment on the company, an overview on price, color management, design options, papers, proofing, shipping and turn-around time, and general comments making for a handy reference.

Following is the list of companies reviewed along with the top level comment for each company.

  • Asuka identified as having the most high-end professional options with an emphasis on producing high-end coffee-table books. Said to be a favorite of wedding and portrait photographers.
  • Apple identified as having the most integrated work flow. I had no idea that Apple (yes that Apple) offered print services.
  • Blurb identified as having the easiest user interface.
  • Fastback Creative Books identified as providing the most personal attention.
  • Embassy Pro Books – said to have the most sophisticated color management.
  • Lulu identified as having the best book promotion which is logical as Lulu is geared towards using its web site to sell the products created by its content authors.
  • Mypublisher identified as having the most deals offered.
  • Pikto identified as having the biggest range of prints.
  • Paperchase identified as having the most creative options.
  • Sharedink identified as having the best special options.

Based on several of the top line comments, it does look like the reviewer wanted to have something positive to say about each and every pod (print on demand) service. The two services with the best general comments with respect to publication quality were Asuka and Pitko. One useful insight the reviewer provided was "if creating a small number of high-quality portfolios to impress special clients is your goal, a smaller company with an emphasis on color management and customer service might be ideal." Another tidbit was contained in the description of the Lulu service. With Lulu you can purchase an ISBN for your book as a part of the publishing process. An ISBN is the code used to categorize and identify books. If your book has an ISBN then it can be added to the various book publishing databases as well as Google Book Search. No mention was made as to whether or not the other nine services had this as an option.

My copy of American Photo magazine is now recycled. However, I have kept the pages for the "Closeup: Photo Books On Demand" article as a reference for the future.

The Illustration

I used a digitally manipulated photograph of a rose to illustrate this article. The original photograph was taken while on a trip to Arizona in 2007. I used Photoshop to extract the rose from the background and then applied a few filters on separate layers with different blending options to create the final image.

Flickr, the Library of Congress, and Titanic Survivors

Thursday, January 17th, 2008
Titanic survivors along side Carpathia
Library of Congress image of Titanic survivors alongside Carpathia

The Library of Congress has just released over 3,000 royalty free photographs on Flickr. While this represents just a tiny fraction of the Library’s 1 million plus digital images, it does provide a new avenue of access to the collection.

The release consists of two collections. The 1930s-40s in Color collection features 1,615 pictures from the Farm Security Administration and Office of War Information. The News in the 1910s collection consists of 1,500 black and white photos from the George Grantham Bain News Service which even includes a photograph of George Washington’s teeth. Together these two image collections provide a fascinating look back at American history of the early to mid-20th century.

One of the photographs that I came across while going through the collection was the image shown above: TITANIC survivors on way to rescue-ship CARPATHIA. If you examine the full size image of the photograph you will see that it doesn’t look quite right. Also interestingly the photo is dated as “between 1910 and 1915″. I found this curious since the exact date of the recovery of the Titanic’s survivors is a matter of record (April 15, 1912). So is it a photograph of one of Titanic’s lifeboats – or just some generic or staged lifeboat image that the news service labeled as being of survivors of the Titanic?

An excerpt from the full size version on Flickr is shown in Figure 1 below.

Titanic survivors, Flickr full size
Figure 1. Full size section of Titanic survivors in lifeboat being rescued by the Carpathia.

I next went to the Library of Congress’ site and downloaded their full size scan (22 megabytes). Shown below is a full size excerpt of the two passengers from the rear upper left of the lifeboat.

Library of Congress Titanic scanx
Figure 2. Full size excerpt from the Library of Congress’ scan.

From this high resolution version, it appears obvious that the original glass negative has been retouched in the form of someone inking in black lines in order to “improve” the picture. In my opinion the emotional impact of the image suffers as a consequence and the poor quality of this “improvement” serves as a visual distraction to the viewer

I recommend that you take a trip over to the Library of Congress Flicker Photograph Collection and browse through the collection. For more information about the Library of Congress photographs on Flickr visit the Library of Congress Prints and Photographs Reading Room. The full digital image collection of the Library of Congress can be browsed at the Library of Congress Prints and Photographs Online Catalog where over 1 million digitized images are available.

STS-117 Atlantis and International Space Station Pass

Wednesday, June 20th, 2007
STS-117 Atlantis and International Space Station Pass
STS-117 Atlantis and International Space Station Pass, June 20, 2007

It’s been many years since I’ve gone outside for the sole purpose of watching a satellite or the Shuttle pass overhead. Before there was the Internet, there was a DOS program called SatTrack I think. Or maybe it was STSPlus. I seem to recall that the author was from Alabama. Anyway I would feed in the orbital elements to see what was going over and head out for a look. Seeing the Mir space station was a favorite of mine. When I learned that tonight both the Space Shuttle Atlantis (STS-117) and the International Space Station would be passing over, I decided to grab my digital camera and try to capture the moment, something I had not previously done.

Before heading outside, I reconfirmed the details of the pass using data from the Heavens Above web site. Following is the most pertinent data:

STS-117

Event Time Altitude Azimuth Distance (km)
Rises above horizon 21:49:57 0° 300° (WNW) 2,120
Reaches 10° altitude 21:51:59 10° 295° (WNW) 1,284
Maximum altitude 21:54:47 47° 217° (SW ) 458
Enters shadow 21:56:03 25° 158° (SSE) 727

ISS

Event Time Altitude Azimuth Distance (km)
Rises above horizon 21:49:58 0° 300° (WNW) 2,121
Reaches 10° altitude 21:52:00 10° 295° (WNW) 1,285
Maximum altitude 21:54:48 47° 217° (SW ) 459
Enters shadow 21:56:04 25° 158° (SSE) 729

The visual magnitude for Atlantis and ISS were given as -0.9 and -0.4 respectively. This combined with the pass times told me that STS would be in the lead as the pair moved across the sky from northwest to southeast and that Atlantis would be the brighter of the two. I grabbed my pager and set its alarm to sound about two minutes before the start of the pass.

Stepping outside, I quickly inspected the sky. While it was not the best of skies, it was clear enough that sighting the space shuttle and space station pair wouldn’t be a problem. Me and my youngest son Thomas then walked to a near-by soccer field, which has a good horizon line, about 10 minutes before the pass. I wanted to have time to get set up and to experiment with shooting images of the Moon using a variety of settings. The last thing that I wanted to be doing was fiddling with camera settings while the pass was in progress.

My son Thomas gets credit for being the first to spot the pair as they traveled over our site. I was able to take several shots while simultaneously trying to answer my son’s questions about what he was seeing.

Following the pass, we headed back home. My son was somewhat disappointed – he expected to “see” the shuttle and the space station. His disappointment diminished when I explained to him how much farther away the shuttle and space station were as compared to the commercial jets that we observed at approximately the same time.

In the picture shown here, Jupiter is the bright “star” in the lower left hand corner of the picture. The bright streak of light in the center of the picture is the Space Shuttle Atlantis and the slightly dimmer streak of light in the upper right hand corner is the International Space Station. The pair were about one second of time apart and were traveling from the upper right to lower left in the frame.

Following are the camera settings used for the above photograph:
Nikon D50
2007/06/20 21:02:54.5
Compressed RAW (12-bit)
Image Size: Large (3008 x 2000)
Lens: 28-80mm F/3.3-5.6 G

I believe that the best part of this photographic experience was taking the opportunity to use my digital camera in a way I hadn’t previously. Novel shooting situations should be sought out, not avoided.

Ad Astra, Jim

A Review of Serif PanoramaPlus 1

Wednesday, May 23rd, 2007
Before and After Using Serif PanoramaPlus
Which Flag Do You Prefer? Before and After Using Serif PanoramaPlus 1

I was in a local bookstore last week going through the magazine section and pulled the current issue of the astronomy magazine BBC Sky at Night. I’m in the habit of going through all the astronomy magazines in search of interesting articles. Unfortunately for Sky at Night I’ve never came across an article in their magazine that would make it worth its price. Looking at the May 2007 issue, it wasn’t what was inside the magazine that grabbed my interest but what was on the CD that comes with the magazine.

The CD has a full version of Serif’s PanoramaPlus, version 1. This program automates the creation of panoramic images given a list of individual source images. Previously I had created my panoramas by using Adobe Photoshop’s Transform Tool and layer masks. Needless to say the Transform Tool is definitely suboptimal – especially when it comes to altering the geometry of the individual images. While I wasn’t thrilled that as a part of the software activation process I had to call the UK offices of Sky at Night, I figured that would be cheaper than going out and buying the software. What bugged me about this is that for all other magazines containing CDs with full versions of software being offered, I’ve never had to make a phone call to activate the product: either it was ready to go or all I had to do was point my browser at the specified web page to complete the registration.

Fortunately the software did have a one time use without registering so that I could fire it up and test it out. I fed the program a total of 11 images from an Apollo 16 EVA to merge. Their combined file size was 8.5 megabytes. PanoramaPlus quickly stitched them together and as far as I could tell from the software’s preview window, had done a good job of it.

The final step was to export the newly created panorama. Therein lies the source of my disappointment. The only export format available was to save as a jpeg. Not only that but there was no option to specify image quality and no documentation identifying what compression setting the software was using. The other shock was the size of my new panorama – just 3000 pixels wide. PanoramaPlus had taken 11 separate images with a combined width of 25,740 pixels and combined file size of 8.57 megabytes and created a panorama just 3000 pixels wide with a file size of 880K.

As a before and after comparison I took the American flag from the panorama and enlarged it to match the flag in one of the source images. The comparison of the two flags is shown at the top of this article. Note that the image shown is a scaled down version of the full size comparison. On the left is the original source flag image and on the right is the flag image from the PanoramaPlus panorama, upsized to match the size of the original flag. The qualitative difference is obvious.

Going to the Serif web site, I see that they are now on version 3 of the software so it is probably no longer the same product. Bottom line: if you’re thinking of buying the May 2007 issue of Sky at Night because of the PanoramaPlus version 1 software, don’t – big mistake. And the special upgrade offer they are running in the magazine: if you’re in the U.S. and paying in U.S. dollars, the standard price for the software is cheaper than the Sky at Night special “discount.”
Ad Astra, Jim
