Free Software Alternatives to Adobe CS6

Tuesday, May 14th, 2013

Adobe CS6 Alternatives
Adobe CS6 Alternatives

In 2012 Adobe released CS6. What set this release apart from previous versions was the licensing path that Adobe has chosen. For more information about the Adobe Creative Cloud model, see Adobe’s Creative Cloud FAQ.

While I have been using Photoshop since Photoshop 5, it wasn’t until CS4 was released that I bought my first full Adobe suite. Adobe Design Premium CS4 included:

  • Acrobat 9 Professional – for PDF creation
  • Dreamweaver CS4 – for web site creation
  • Fireworks CS4 – preproduction and mockup for web page creation (combines Dreamweaver and Photoshop features)
  • Flash CS4 Professional – Flash creation
  • Illustrator CS4 – for creating vector graphics and for graphic design
  • InDesign CS4 – for desktop publishing
  • Photoshop CS4 Extended – Photoshop with 3D capabilities

Of the programs that make up the Design Premium suite, Photoshop is where I live and is the application which I am most qualified to comment on. I must say that I have become increasingly disenchanted with Adobe’s approach to the software/graphics market. This has strongly influenced my decision as to whether or not to continue to upgrade my Adobe products. From one review of CS6 we have this summation:

"No creative professional will deny the need for Adobe Creative Suite, and 2012′s version, CS6, focuses on some of the toughest demands designers face in an interactive, digital, multimedia landscape."

From a corporate perspective, that is probably true. Once upon a time you could not get criticized if you bought IBM products. With the advent of the desktop computer, Microsoft became the safe buy. With respect to visual creative software, Adobe holds the corporate safe to buy crown. But I am not a corporation. Nor do I have the deep pockets that would allow me to continue to ride the Adobe Upgrade Train.

So this article is for those who are in search of an alternative to Adobe. For this article, I am only going to look at those alternatives that are free. However, I am not going to do this for every program that is a part of the Design Premium package – just those that I use.

Acrobat 9 Professional

When it comes to creating PDFs, I have never had to make use of the advanced features provided by Acrobat. Instead I have found the capabilities of OpenOffice/LibreOffice Writer’s Export to PDF function to be sufficient for my needs. I will note that Acrobat has come in quite handy when it comes to editing PDFs that I did not create.

If all you need is to create simple PDF versions of documents you’ve created then I suggest using Writer – which is available as a tool in either OpenOffice or LibreOffice.

Dreamweaver CS4

While I have experimented with using Dreamweaver as a web site creation tool, I’ve always had a certain disdain for WYSIWYG web site creation tools. Once upon a time I used NetObjects Fusion professionally. If Microsoft FrontPage was a nightmare, then Fusion was a dream. But I never opted to use Fusion for my personal web sites. I much preferred the hand-coded approach – and still do. As the focus of this article is on graphic software, I will comment no further on Dreamweaver.

Fireworks CS4

Fireworks I’ve used a couple times just to give its web page creation tools a try. As I am not engaged in web design as a full time professional pursuit, I was unwilling to devote time to learning how to use this software, preferring to create quick graphic mockups in Photoshop.

Flash CS4 Professional

I confess that I have never even opened the Flash application. I have never had an interest in using Flash to create digital art and as a web designer have deliberately avoided using Flash for the web sites I’ve done – a strategy that in hindsight appears to have been the right one to follow. So no recommendations here.

Illustrator CS4

I’ve never been much of an Illustrator user so am not really qualified to testify on its strengths and/or weaknesses. All I can say is that it has worked for me when I’ve needed it.

As to free alternative vector software it seems that Inkscape is the most popular option. It is worth noting that Draw, which is another of the software components of both OpenOffice and LibreOffice, is also used to produce vector-based art and diagrams. Draw is the one component of OpenOffice/LibreOffice that I have never used. (Note that my chief reason for migrating from Microsoft Office to OpenOffice was that I viewed OO Impress as a superior product to MS Powerpoint at that point in time). Inkscape is available for the Linux, Mac, and Windows platforms.

Inkscape – inkscape.org

InDesign CS4

My use of InDesign has been minimal. For the most part the documents I create are simple enough in terms of layout that they can be created in OpenOffice/LibreOffice Writer. However, for people who need the capabilities of a desktop publishing (DTP) application then Scribus is worth a look. This free software is available for the Linux, Mac, and Windows platforms. Oh – it is amazingly enough also available for those running OS/2 Warp (my favorite operating system of all time!).

Scribus – http://www.scribus.net/canvas/Scribus

Photoshop CS4 Extended

Photoshop – the software I love to hate due to its frequent crashes and operational glitches. I must say that it seemed to me that each new version of Photoshop crashed more often than the previous version. I was able to eliminate many of the crashes with CS4 by turning off all OpenGL features – which has the unfortunate side effect of reducing Photoshop’s functionality – but I prefer losing features to losing work!

As to free alternatives to Photoshop, there are many. The oldest and most well known of the free alternatives is GIMP. My use of GIMP has been limited but fruitful. My main problem with GIMP is that I would have to learn the GIMP way of doing things. Having used Photoshop for so long, I just know how to do what I want to do without having to think about it. Migrating to new software is always painful in that time must be spent in learning both the GUI and the tools. GIMP is available for the Linux, Mac, and Windows platforms.
GIMP – www.gimp.org

It is not just photographers using Photoshop, but artists as well. Photoshop’s paint brush engine is quite powerful and allows artists to create many painterly effects – serving as a challenge to Corel Painter. One of the free, open source painting software alternatives is Krita. Krita started out as KImageShop, a component of KOffice, a free open source office suite, which was available for Linux, Mac, and Windows. Calligra has apparently stopped development on KOffice (2012) which does not impact Krita. The next version of Krita, 2.7, is expected to be released next month.

Krita is available for Linux and Windows with a beta version available for Mac OS/X. Windows users note that the "highly experimental MSI installer" installs the entire Calligra Suite which includes the applications Words, Stage and Sheets, Flow, Braindump, Karbon and Krita.
Krita – krita.org

Another free open source painting program for artists is MyPaint which is available for the Linux and Windows platforms. What I find appealing is this part of the site’s description of their software: "MyPaint supports pressure or tilt sensitive graphic tablets and comes with an easy-to-use brush collection. There is a complex interface for creating your own brushes, focusing on brush dynamics (changes with speed, pressure, randomly)" Creating my own brushes is one of the Photoshop features that I regularly use so this capability is a must for me.
MyPaint – mypaint.intilinux.com

Adobe Camera Raw

While not listed as a separate product, Adobe Camera Raw (ACR) played a big part in my decision to upgrade from CS to CS4. Adobe did a great job with ACR. In my opinion, it was the best modification made to what was a part of my core work flow as I do a lot of digital photography.

For photographers who are looking for a free alternative to Adobe Camera Raw, one product that is highly rated is RawTherapee which is available for the Linux, Mac, and Windows platforms.

RawTherapee – rawtherapee.com

In Summary

For me, the hardest part of migrating to new software is the loss of knowledge and experience I acquired using my current software. When I started with Photoshop there really were no good alternatives out there. For my money, I prefer to stick with my CS4 software vs upgrading to CS6 or migrating to alternative solutions. However I do anticipate the arrival of a day when I judge some free alternative to my Photoshop CS4 to be of superior quality.

In closing, for artists or photographers who are just starting out and do not have a history of using Adobe products to consider and are not seeking employment that requires a knowledge of Adobe products, this is a great time to investigate the many free software options that are available to you.

Happy Computing, Jim

Spam Spam Spam Spam Comments

spam spam spam
Spam spam spam spam

A week ago I upgraded my blog’s version of WordPress. A big downside of that upgrade was that a couple of "tricks" I had put in place to defeat the spambots were undone. As a consequence my inbox for moderating comments found itself filled with around a thousand comments. Unwilling to dig through a mountain of garbage I simply deleted everything. If I deleted your comment, my apologies. Earlier today I completed the modifications to my blog that will hopefully make me once more invisible to the spambots. Of course this doesn’t stop those humans low enough to stoop to spamming but that’s a volume I can deal with.

Now one of the goals of a blog is to attract comments but not all comments are created equal. All too many blogs allow spam comments advertising all kinds of garbage to be published. Keeping spammers at bay has led me to pursue several tactics. One that is invisible to the visitor are the WordPress "tricks" I mentioned previously. Another layer of defense is to use a captcha to keep robots out. I use a very simple captcha. While some captchas seem to have as their top priority keeping robots out – at the expense of also keeping people out as well, I’ve gone with a simple captcha that anyone should be able to read – even some bots. Another line of defense is to have moderation turned on. That means that no comment appears on my blog until I approve it (which can unfortunately sometimes lead to significant delays between the time that someone makes a comment and the time I actually approve the comment.) And of course there are always the anti-spam WordPress plugins.

Having had to deal with many comments over the years, based on my experience I have found that comments fall into four broad categories.

Category 1: The Blatant Spam Comment

These comments have nothing to do with the blog post and are simply a commercial directing readers to some web site to buy some product. I’m amazed that this class of comment is so popular because that popularity means that they work often enough to make it worth the spammers time and energy. These spam comments take three forms. First is the url the spammer enters into the address field; second is the link they include in the text of their comment; third is the sales pitch they make in the body of their comment.

Category 2: The Sneaky Spam Comment

These are comments that are little more than a line saying "great post" or "I love your blog" In other words the spammer forgoes the posting of a link and sales pitch in the body of the comment. The spam component is in the url they provide, like loweryourmortgage.dummy (I put in the .dummy part because only a dummy would follow a link like that). The publishing of such comments provides two benefits to the spammer. First there is the chance that someone will be dumb enough to click the link and visit the site. The second benefit is that the link becomes indexed by the search engines and potentially improves the spammer’s search engine ranking.

Category 3: The Generic Comment

The only difference between this comment and the Category 2 Sneaky Spam Comment is the absence of a spam link. I take these short congratulatory comments as directed to me personally rather than as comments that others are meant to read. So while I smile and appreciate receiving these complimentary comments, I do not publish them on my blog because they do not provide original information that benefits the next reader.

Category 4: The Golden Comment

These are the rarest of comments. They are comments that add value to the post. They can be as simple as the asking of a relevant question, or an expansion on what I have written, or a reference to a source of relevant information on another web site. In short these are comments that leave the reader more enlightened.

Conclusion

So if you’re visiting my blog and leave a simple compliment like "nice article", please don’t be surprised if it is never published. While I do appreciate the feedback, I only publish those comments that leave the readers that follow more enlightened about the subject at hand.

Ad Astra, Jim

Goodbye Facebook Fan Page Widget

Wednesday, December 12th, 2012

Artsnova Facebook Fan Page
The Artsnova Facebook Fan Page

As a consequence of a change in Facebook policy I’ve decided to drop the Facebook widget promoting my Facebook Artsnova fan page from my blog’s sidebar. I also plan on changing how I use my Facebook fan page. The policy change that has led me to this course of action was Facebook’s decision to limit how many of a page’s fans actually see the posts in their news feed. This was done so that Facebook can monetize posts. You see you can still reach all your fans – if you are willing to pay for it. This is implemented via the relatively new Facebook Promote option.

With this policy change, unless you pay to promote your posts the reach of your posts is decreased by approximately 85 percent on average. Quoting from the article Paying For Promotion (referenced below):

Dave Seligman, founder of popular geeks culture blog Geeks of Doom told me recently that "Of the 18,000 fans of our Facebook page, only about 900 (5%) of them ever have the opportunity to view one of our posts at a given time."

My Solution

My solution going forward will be to use my Facebook fan page only to post announcements of new posts on my blog. Also, instead of creating short original content posts on Facebook, I will move those posts to my blog. Who knows – perhaps Facebook’s policy change is a good thing for me since it will mean more new content on my own blog rather than on Facebook.

Goodbye Facebook widget. Note that I never liked the way you munged my posts to fit your widget anyway.

Google Image Search Now Dumber

Tuesday, November 13th, 2012

Google Advanced Image Search
Google Advanced Image Search
What Happened to the Image Size Filter?

It seems that with every passing year Google throws away some search capability that I found useful. The latest victim is Google’s Advanced Image Search tool. In using Google’s Advanced Image Search one of the features I used most regularly was the ability to filter results based on image size. I had the option of doing this either at the time I was entering my search criteria or from the filter sidebar on the search results page.

When I’m searching for a photograph I don’t want to be bombarded with every thumbnail image that has a tie in to my search term(s). I therefore ALWAYS specify a minimum image size. Of course when I am specifically looking for icons and such I specifically want small images. I have found the ability to search based on image size the single most useful image search filter Google offers.

Earlier today I headed over to Google’s Advanced Image Search to look for an image of Uncle Sam to use for a presentation I was working on. I looked once, twice, thrice and could not find the image size option. Thinking something was askew with the page itself, I reloaded the page but still no option to specify the image size. Thinking that maybe I’d be able to select an image size on the search results page (an option I had frequently used in the past), I pressed enter to start the search. Yikes. Google has eliminated ALL search options from the sidebar area on the image search results page. What on Earth are the Google developers thinking? Perhaps I was only imagining the size filter?

Google Advanced Image Search Help Page
Google Advanced Image Search Help Page

Nope. Visiting the image search help page, there it is – the image Size option. So Google’s Advanced Image Search is now much less advanced than it used to be, as well as much less useful. I can’t imagine what justification there was for removing not only the image size option, but also the entire search results sidebar. I hope that Google’s decision to drop size as a search option generates enough uproar that Google brings back what I found to be the single most useful filter that the Advanced Image Search tool offered. I also hope that they bring back the results page filters sidebar that allowed me to change my search options without having to return to the main site search entry page.

My Art Blog Posting History

Saturday, October 27th, 2012

Blog Post History Bar Chart
Blog Post History Bar Chart

Checking on the date of my previous blog post immediately after posting AVG Anti-Virus and Comodo Firewall To The Rescue, I was slightly shocked to see that it was my first blog post since August 18th, 2012. It seemed to me that I had posted much more frequently in the past and I became curious about my track record. Just how well does my current blog posting frequency compare with previous years?

My first step was to collect the necessary data. I logged in to my phpMyAdmin account and ran the following SQL query on my WordPress database:

SELECT `wp_posts`.`post_title` , `wp_posts`.`post_date`
FROM wp_posts

It turns out that I’ve written 210 posts since starting this blog on Oct 13 2006, which was 2206 days ago. Considering the number of days that have elapsed since that time, that works out to just one post every 10 days. That doesn’t sound so bad until I look at the average period between posts for 2012 – which is one post about every 17 days. 2012 compares poorly with 2008 which was my best year with me averaging one post a week.

My next step was to write a Processing program that would read my data file and graphically summarize my monthly posting record (yes I could have produced a bar chart with Calc or Excel but where’s the fun in that?). The graph above is the output from that program. Each vertical bar represents the total number of posts for that month with each year being assigned its own color. A quick scan makes it clear that my posting frequency/quantity has declined. Clearly my posting isn’t what it used to be.

One thing I plan to do to up my posting frequency is to blog about some of my art projects, principally small screen-size experiments with digital painting, photo manipulation, and algorithmic art techniques.

So until next time (which hopefully won’t be too long a time) I leave you with the words of American humorist Robert Benchley (1889-1945) who quipped "It took me fifteen years to discover that I had no talent for writing, but I couldn’t give it up because by that time I was too famous."

AVG Anti-Virus and Comodo Firewall To The Rescue

Thursday, October 25th, 2012

AVG Anti-Virus and Comodo Firewall
AVG Anti-Virus + Comodo Firewall

ZoneAlarm Review: Strike 1, 2, 3 – You’re Out

The McAfee anti-virus software that came installed on my Dell laptop was about to expire so I decided to search for a free alternative. Even though my license was good for another 10 days, I decided to get rid of McAfee ASAP as its daily pop-up reminders telling me that it was about to expire were causing Windows Explorer to hang.

My top replacement choices were Avast, AVG, Comodo, and ZoneAlarm. Based on protection and not performance review grades from several sources, I decided to go with ZoneAlarm Free Antivirus + Firewall. Sunday night I uninstalled McAfee and downloaded and installed ZoneAlarm Free Antivirus + Firewall. The install went off without a hitch – although it took a fair amount of time to complete.

Strike 1 was when I tried to use my printer. Attempts to print to my USB-connected (not network-connected) Epson printer failed. Testing revealed that the problem disappeared as soon as I turned the firewall off. Searching the ZoneAlarm forums I found that others had experienced similar problems. I configured ZoneAlarm’s firewall based on the recommendations I found there. These changes did not fix the problem. So it appeared that if I wanted to use my printer, I would have to turn the ZoneAlarm firewall off – an unacceptable option.

Strike 2 occurred when I set up an account to ask about the firewall/printer problem on their forum. I registered, then clicked on the activation link in the email they sent me and my account was activated. Unfortunately 12 hours later I was still waiting for authorization to post questions to their forums.

Strike 3 occurred when I tried to use my clipboard with OpenOffice Calc. The Copy operation took some time to complete but when it came to pasting, Calc would just hang and I had to use Windows Task Manager to force a shutdown. Again searching the forums I found a similar post with regards to Microsoft Office Excel but no solution.

It is worth noting that ZoneAlarm is identified as an under performer in terms of system utilization in the reviews I saw but this took a back seat to my desire for protection – the category in which ZoneAlarm held a slight advantage. And I definitely noticed that my laptop behaved in a clunkier (yes that is the technical term) manner than before with McAfee, which is a rather poorly rated anti-virus solution itself.

With ZoneAlarm failing to meet my usability expectations, I turned to my backup choice – AVG Free Anti-Virus and Comodo Firewall. Uninstalling ZoneAlarm, I first installed the Comodo firewall software. Wow – opening a document and printing it worked perfectly – unlike with ZoneAlarm which apparently refused to trust my printer. For the novice, it is worth noting that Comodo is more demanding of the user in terms of configuration and the issuing of alerts – which I personally prefer. I prefer it when my computer asks me what it wants me to have it do – versus the alternative of it thinking for itself. Give me the wheel and let me drive – which may not be for everyone.

My next step was to install AVG Anti-Virus Free 2013. I would like to point out that I always choose the custom install option when given the choice. I do this because so much free software these days installs additional components that are of little or no benefit to the user. Personally I want to know as much as I can about what an installer is doing to my computer. With respect to AVG, I did opt to install the AVG Surf-Shield but have not yet seen any benefit. There was a similar toolbar with ZoneAlarm but as far as I could tell it provided no benefit either (at least none has been apparent in terms of the very limited surfing done with either/both).

One nice benefit of AVG Anti-Virus Free is that the install says they offer free 24/7 support. Wow. ZoneAlarm offered none – just their forums. Testing, things appear to be speedier with AVG when it is performing a full scan than with either McAfee or ZoneAlarm when not scanning. Also I can now copy and paste with my clipboard when using OpenOffice Calc.

The Bottom Line

The bottom line is that you may experience different results. Also, if you are pursuing the free anti-virus/firewall route, it could do you no harm to have a couple of alternative options ready to go in the event that your first choice fails to meet your expectations.

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.

Free Software Downloads: Bryce, Daz Studio, and Hexagon

Monday, February 6th, 2012

Bryce, Hexagon, DAZ Studio Free Download
Bryce, Hexagon, DAZ Studio Free Download

Saturday I learned that DAZ (Digital Art Zone) is making available the following software as free downloads until February 29:

  • Bryce 7 Pro 3D Landscape Software (retail price $249.95)
  • Hexagon 2.5 3D Modeling Software (retail price $149.95)
  • DAZ Studio 4 Pro 3D Software (Winner of 3D World’s 2011 Software Innovation of the Year Award) (retail price $429.95)
  • 3D Photoshop Bridge (retail price $199.00)

In addition there are a number of free models and textures available as well. The total retail price of the basket of software, models, and textures that I downloaded was $1,350. The one requirement is that you subscribe to their newsletter – meaning you give them your email address.

Note that your order will show up in the Available Downloads link from your Account Dashboard and that you are allowed 4 downloads of each product you have ordered. The serial numbers for your software are retrieved separately via the Available Serial Numbers link. All downloads are in the form of executable files. The largest downloads are:

  • Bryce 7 Content – 670 meg
  • Daz Studio 4 32-bit – 441 meg
  • Daz Studio 4 64-bit – 439 meg
  • Bryce 7 Pro – 254 meg

I’ve never used Hexagon or DAZ Studio Pro but Bryce was the first 3D software I ever used – back when it was version 3. I haven’t used it in years but I still have a large collection of Bryce files and it would be nice to perhaps resurrect some of them. The name is taken from Bryce Canyon, which I had the pleasure of visiting a few years ago (there’s a photo of me at Bryce on the bottom of my home page). The first version of Bryce was released as a Mac only product in 1994. Version 3.1 of Bryce 3D was released in 1997 by MetaCreations Corporation – this was when I first purchased Bryce. Bryce was acquired by the Corel Corporation in 2000 who released version 5 of Bryce in 2001. Bryce was sold to DAZ in 2004 who has gone on to release versions 5.5 and 6.0 with Bryce 7 being released in 2010. Bryce 3D has always been looked down upon as a package for newbies with limited capabilities. While these criticisms are true, it’s important to remember that for many digital artists, Bryce was what opened the door for them to explore the world of 3D graphics software. It’s low price and easy-to-learn interface made it a perfect software solution for those digital artists looking to get their feet wet.

Hexagon is a tool for creating 3D models. According to the DAZ web site:

Hexagon delivers all the tools a graphic artist needs to create detailed 3D models ready for final render. Packed with features such as; DAZ Studio Bridge, sculpted primitives, freehand modeling brushes, micro-displacement modeling tools, comprehensive UV-mapping modules, advanced 3D paint, and instant ambient occlusion. Hexagon provides you with all the options of expensive competitor software, but at an affordable price.

I’m not sure what to make of 3D Photoshop Bridge. The DAZ web site describes it as a " DAZ Studio plug-in designed to connect the power of Photoshop with the unlimited content possibilities of DAZ Studio. It’s the next step to maximizing your creativity. It will also save you money by eliminating the need for costly photo shoots and stock imagery, save you time with quicker rendering, and save your brain by swiftly and easily integrating the best features of DAZ Studio and Photoshop…Easily pose characters and objects three-dimensionally with the 3D Photoshop Bridge while in DAZ Studio,"

Of course it would help if I knew more about Daz Studio. In this case, download first then investigate was my motto. According to DAZ:

DAZ Studio is a feature rich 3D figure customization, posing, and animation tool that enables anyone to create stunning digital illustrations and animations. DAZ Studio is the perfect tool to design unique digital art and animations using virtual people, animals, props, vehicles, accessories, environments and more. Simply select your subject and/or setting, arrange accessories, setup lighting, and begin creating beautiful artwork.

The free 3D software is available via download only from DAZ3D.com between now and February 29, 2012:

Note that there are a number of video tutorials available for Bryce, Hexagon, and DAZ Studio on YouTube.

Here’s to happy and creative computing. Jim

Digital Art and Unintended Consequences

Monday, December 12th, 2011

Example of unintended consequences in digital art
An example of unintended consequences in digital art

Yesterday I was working on an image processing program to use as a part of my art creation workflow. I was writing a program to texturize an image so that I could incorporate the output as a layer in a Photoshop document.

As a part of the development process, I decided to use as the source image the painting Paris Street, Rainy Day by French artist Gustave Caillebotte. This is the same image that I used to serve as the "discovered" painting for my article and applet Particle Painting: Name That Painting.

To create the look I was after I needed to use the third dimension, aka the z axis. The addition of the z axis made it possible for me to use that axis as the source of distortion while keeping the correct color information in the x,y plane. Using 3D also allowed me to rotate the image relative to the "camera" thus introducing another level of distortion.

All was going well until I made one small change to the variable I was using to control the distortion along the z axis. This single change took what had been output that was recognizable as the source image and produced an image that was completely unrecognizable. I’ve used a cropped version of that output to illustrate this post. Below is a side by side comparison of the source image that my program used as input and the resulting output.

Caillebotte's Paris Street, Rainy Day before and after
Caillebotte’s Paris Street, Rainy Day before and after.

This can not be called an algorithmic oops or a glitch. Rather it is a case of parametric discovery. It is this discovery opportunity, whether by design or by accident, that makes digital art such an interesting and revolutionary arena for artistic creation.

It remains to be seen whether or not I will ever make use of this program in a production environment. Even if I don’t, what I learned during the process will serve me well in the future. So remember the golden rule of digital art: never be afraid to experiment.

Tutorial on Recursion Published in CMD Journal

Wednesday, June 15th, 2011

CMD Journal cover
CMD (Computational Media Design) Journal cover

This spring it occurred to me to write an article about recursion for my Artsnova web site. I must confess that I really haven’t put any of my recursively created algorithmic art on my web site or made it available for sell but as a programming artist, I find the concept of recursion fascinating. The principal interest for me is in the creation of the program that creates the art. In other words, what excites and interests me most is the act of creating the recursive algorithm. The article/tutorial was to be one in a three part serious about the three "R’s" of algorithmic art: Random Numbers, Recursion, and Repetition. The tutorials were to be written using the Processing platform rather than C++ as Processing seems to have broader appeal to programming artists and is simpler to learn for people new to the field.

Shortly after completing the recursion tutorial I learned of a new magazine being published: CMD (Computational Media Design) Journal. From the CMD Journal website comes the following description of the publication:

THIS IS WHY WE’RE HERE
We are interested in the exploration of the intersections of art, design and computer science to encourage new ways of seeing, thinking and creating in order to empower and inspire inventive, innovative and creative research, artistic and design practices.

THIS IS WHO WE ARE
CMD Journal is an educational magazine about computational media design. The magazine was started by Marjan Eggermont and Laurel Johannesson in 2010 both to learn more about and to become a forum for this relatively new field.

Rather than publishing the article/tutorial on my web site, I decided to submit it to CMD Journal. I’m pleased to say that my submission was accepted and appears in issue 2 of the magazine, which is now available online.

I did have to do some trimming of the tutorial in order to have it fit within the submission word limit. Now on my long list of to-do items is an entry to create an expanded version of the tutorial to use for my three "R’s" of algorithmic art set of tutorials.
