New Art, a Poem, and Digital Art Reflections

Impression of Water Lily
Impression of Water Lily

I just added new art to my Nature Gallery. Impression of Water Lily is a digital semi-abstract impression of a water lily. This is what I hope to be the first in a series of evolving impressions of similar botanic pieces. My objective is to experiment with different digital techniques of representing various flower-like structures found in nature.

Regarding computer art, here’s a poem I’ve just written that in part reflects the intellectual challenges faced by the digital artist.

I really like computer art
Painting with pixels is sweet
But reading all those manuals
Is anything but a treat.

One advantage traditional artists have over their digital artist counterparts is that after all these years paintbrushes are still paintbrushes and pencils are still pencils. Given the static nature of their tools, traditional artists can focus on refining their mastery of their tools. The same is not so for the digital artist. It frequently happens that even before one can master a particular digital tool, or explore its full range of potentialities, a new version of that tool or another tool comes along to replace it and the learning process begins anew.

The tools I learned how to use when I was first exposed to digital art (computer art as it was then known) in the early 1980’s are extinct today. In fact, today I’m only using one of the tools that I learned and was using in the 1990’s. It is the one graphics software that I have used the longest. I started with Adobe Photoshop 5 circa 1999 but today’s Photoshop CS4 bears little resemblance to that first version.

I fully expect this rate of change to continue. As operating systems progress and change; as old hardware dies; as graphics software packages cease to be supported and their owning companies go out of business; and as new graphics software offerings supercede in functionality capabilities of older software; we digital artists will remain on the upgrade treadmill with our noses buried in the manual of our newest digital tool.

Bionic Cnidaria Computer Art

Bionic Cnidaria
Bionic Cnidaria

Had a tough time deciding whether or not Bionic Cnidaria belonged in the Computer Art Gallery or in the Nature Art Gallery. One the one hand it is meant to be a tribute of sorts to the phylum of cnidaria, which includes jellyfish. On the other hand it is an artifical creation of my own imagination. In the end I decided to add he/she/it to my Computer Art Gallery.

When visiting Chicago’s Shedd Aquarium or Brookfield Zoo, I’m always drawn to the jellyfish and the slow rhythmic fluidity of their movement. Now I need to decide whether or not to create more cnidaria.

Modern Life
Modern Life

I’ll be leaving in a couple of hours to attend an artists’ reception at Advocate Good Shepard Hospital in Barrington. The reception is for myself and fellow artist Eric Hill. It is being sponsored by the Northwest Cultural Council. Eric and I are both artists in the Northwest Cultural Council’s Corporate Art Gallery program and currently have art on display at the hospital.

So here is a chance for you to have some free wine and cheese, talk with Eric and myself about whatever strikes your fancy, look at some art, and have a good time. The reception begins at 5:30pm and runs until 7:30pm. For complete details on the reception, see
Artist Reception at Advocate Good Shepard Hospital, Barrington

The Illustration

To illustrate this post I used a piece of art that I just added to my Technology Gallery. Titled Modern Life it is based on a digital photograph I took a year ago. For more about the piece and to view a wallpaper sized version of the same, see

New Art: Digital Rain

Saturday, February 20th, 2010

Digital Rain digital art painting
Digital Raindigital painting

Added some new art the other day to my Nature Art Gallery - a gallery I’ve ignored for far to long. Titled Digital Rain, this was simply an experiment in painting a heavy rain - so heavy as to make the sky opaque. The idea came to me while watching a rain storm last year while at Bryce Canyon National Park. From my mountain side viewpoint, a heavy rain in the distance connected the sky to earth and was sufficiently heavy so as to obscure the landscape beyond.

It’s a hazy boundary between being clever and the opposite. We frequently see people creating something that forces us to ask ourselves what on Earth were they thinking when they did that? Now I’m not sure if I’m crossing that boundary here but the thought struck me to write a limerick about my painting to accompany this post - the goal being to make this post a little more entertaining. So for better or worse here goes.

My digital painting of rain
won’t pose a challenge to your brain
As fine art it’s not much
But it does give a touch
To the scope of nature’s domain

For details about the painting, visit the Digital Rain web page.

New Art: Emergent Hand

Emergent Hand
Emergent Hand

I had a tough time naming the newest addition to my Computer Art Gallery. Emergent Hand
started out as a landscape scene inspired by what I observed last year while visiting Bryce National Park in Utah. Upon completion of the piece I realized that I had created a hand. In fact, turning it sideways brought to mind that flying Blue Meanie glove from the Beatle’s movie Yellow Submarine. I found the ambiguity of the piece particularly appealing.

To Be Anonymous Added to Computer Art Gallery

To Be Anonymous
To Be Anonymous digital art.

To Be Anonymous is the newest addition to my Computer Art Gallery. Looking at this piece you may find it ambiguous and you’d be right. The subject is anonymity. To the outside observer, everyone in this crowd is anonymous. However, inside this digital painting there is one who, while a part of the group, is separate from it. What you the observer need to work out is this: is that individual turned away from us while the crowd face us, or is it the crowd that has their backs to us and the individual who stares out at us anonymously.

Back tomorrow with another new digital painting.

Atmospheric Disturbance Added to Computer Art Gallery

Atmospheric Disturbance computer art
Atmospheric Disturbance computer art

I just finished adding another work of art to my web site. Atmospheric Disturbance is a piece I created earlier this month and which I’ve added to my Computer Art Gallery.

The piece came about as a consequence of considering the invisible turbulence that a particle, ball, or planet creates when moving through some intangible medium. Actually it all started with thinking about that old idea that there was an invisible ether that permeated all space and which would affect the speed of photons as they moved through that medium.

I added Atmospheric Disturbance to my Computer Art Gallery because of the tools and workflow used to create this piece. This piece was created using a combination of my own personal computer graphics software and Adobe Photoshop.

I must confess that one of the reasons that I make use of my own software dates back to a number of years ago when I would be walking through the art shows at science fiction conventions. At that time the range of graphics software used by digital artists was less diverse than today and I prided myself on being able to correctly identify the software the artist used in the creation of their artwork. Especially easy to identify were those pictures created using either Bryce or Poser.

To escape being typecast it seemed best to avoid using mainstream software - Adobe Photoshop being the principal exception. It also seemed like a good idea to diversify and to not become too dependent on any one software package - once again with Adobe Photoshop being the exception.

In the early days I would write using the C programming language. Once Java came along I began using that language. In fact I’m proud to say that I used Java to create the first (as far as I know) web accessible database of Martian feature names which included cross references to Viking images. Java has changed substantially since then. Some recent and useful books on graphics programming with Java are:

In addition to Java, I also make use of a great extension to Java called Processing. While the Java programming language can be pretty intimidating, that is not the case with Processing and I highly recommend it to anyone even remotely interested in doing their own graphics programming. To learn more visit the Processing web site.

I seem to be getting off topic here so to conclude, for a better view of Atmospheric Disturbance, you should visit the Atmospheric Disturbance web page which has a link to a wallpaper sized version of the image.

Look for another new art addition tomorrow

Jim.

Life Pulse - New Digital Abstract Art

Monday, February 1st, 2010

Life Pulse abstract art
Life Pulse abstract art

I must confess. I’ve not been very good at adding art, either old or new, to my web site. In fact I have a rather large backlog for each of the genres of art that I create. To make amends I plan to focus on adding my newest works of art over the coming weeks. The bulk of this art will be added to my Computer Art Gallery.

The first piece I am adding is Life Pulse. This work is currently on display at the Advocate Good Shepard Hospital in Barrington IL as a part of an exhibit of a selection of my digital art. For more, see Art Exhibit at Advocate Good Shepard Hospital in Barrington IL

Additional information about this digital painting and a wallpaper sized version are at Life Pulse abstract art page. Given that the original is 20 inches wide by 15 tall, not much detail is apparent in the wallpaper sized version. It does however provide a good representation of what the full size artwork looks like.

Check back in a day’s time to see what gets added next. And no, I haven’t yet decided what to add next.

Diffusion Limited Aggregation

Diffusion Limited Aggregation
Figure 1.Diffusion Limited Aggregation Graphic

Over the weekend I spent some time experimenting with Diffusion Limited Aggregation. In computer graphics Diffusion Limited Aggregation is a method for growing or creating shapes that have a nature-made quality and which have a fractal dimension. In nature, this type of growth is seen in coral reefs and crystals. Note the dendritic structure in the illustration above - which reminds me somewhat of ice crystals on a window pane. The concept’s origin is with the paper Diffusion-Limited Aggregation, a Kinetic Critical Phenomenon by T. A. Witten and L. M. Sander that appeared in an 1981 issue of Physical Review Letters.

The growth of structure seen when using the Diffusion Limited Aggregation method results from the random deposition of particles on a surface. The basic rule is that whenever a moving particle finds itself adjacent to a stationary particle, it too becomes stationary and a new moving particle is created to take its place. A typical growth simulation will start off with one or more seed particles - particles which are already stationary. A number of moving particles are then added to the system. The movement of the individual particles is random.

The random motion that the particles undergo is described as a random walk. The path that an individual particle takes is determined by a random process with the two components being direction and distance (think vector). In my implementation of random motion, collisions between moving particles was ignored. The nature of the random walk is related to Brownian motion. Brownian motion is the type of movement exhibited by particles suspended in a liquid medium. Figure 2 below shows the random motion of three particles using the same algorithm as used in the Diffusion Limited Aggregation process that created the growth in the Figure 1.

Brownian Motion example
Figure 2.An example of Brownian Motion

As you can see in Figure 1, the Diffusion Limited Aggregation growth is rather symmetrical. This particular growth would have been more symmetrical except that there were additional growths, cropped out of the image shown, that captured particles that would have otherwise been deposited on the growths shown. There are several other ways to obtain non-symmetrical growths. One method for achieving directional growth is by omitting one or more of the eight moveable directions on the rectangular grid. Another method would be a preferential bias in the detection of adjacent stationary particles.

Diffusion Limited Aggregation can be a very inefficient way, in terms of CPU cycles, to generate growths. Depending on the size of the playing field, the number of seeded stationary particles, and the number and nature of the living particles, a Diffusion Limited Aggregation algorithm can take quite a long time to create a growth of any meaningful size.

Writing a program to create imagery using Diffusion Limited Aggregation was instructive but I do not know whether or not I will ever make artistic use of this technique. However, I have yet to attempt a 3D version which should offer greater artistic possibilities.

June in Review: New Art and a Vacation

Friday, July 3rd, 2009

Self Portrait at Bryce Canyon National Park
Self Portrait at Bryce Canyon National Park

I can’t believe the month of June went by without a single post to my blog but it was a very busy month. Following is a review of my activities for the month. I’ll write later about the drive crash that delayed this update.

It began with my return from the International Space Development Conference in Orlando FL. I arrived at the conference hotel on Wednesday and departed on Sunday with my only excursions out of the hotel being to grab some fast food as a low cost alternative to the hotel restaurants. At the conference I gave a formal presentation on space solar power and an informal presentation about the National Space Society to a group of students from India. I also was a participant in the conference’s space art show. That show was a terrible disappointment to me. There were only a few artists participating and we were hidden in a back corner of the exhibit room with no signage indicating that there even was an art show or that space art was on display. There were also other problems which I won’t go into detail on here. I did take a number of photographs and submitted a selection of them to Ad Astra magazine for possible publication - several of which will appear in the magazine’s next issue.

The next week was spent playing catch-up and preparing for a two week trip to Arizona and Utah. While in Arizona we visited my Mother and did a number of jobs for her around the house. We then took off for a quick tour of three national parks. Our first stop was the Grand Canyon. From their we proceeded to Bryce Canyon National Park in Utah and after a couple days there headed south to Zion National Park. So which was our favorite national park? A poll of the family afterwards gave the award to Zion National Park with Bryce coming in second and the Grand Canyon bringing up the rear. I will write in more detail about my experiences at each of these parks at a later time.

Upon returning home, it took me some time to catch up with email. I also went back to work on my web site. In addition to making a number of minor cosmetic changes to the site and correcting some previously undiscovered errors, I spent some time doing SEO (search engine optimization) work. Earlier in the month I had purchased the book The Truth About Search Engine Optimization by Rebecca Lieb. I’m only half way through the book but am quite impressed with what I’ve seen so far and am using its advice to improve my own site’s standing in the search engines.

In addition to the aforementioned site maintenance, I’ve also added two new art galleries. The first is a Computer Art Gallery featuring art that combines elements of algorithmic art with freehand digital painting. All the art in this gallery will have been created using interactive algorithmic software of my own design.

The second gallery is a Space Art Gallery featuring art that commemorates human space exploration. I previously had a Space Art Gallery that contained astronomical art. All of that art, depicting astronomical scenes including planets, moons, nebula, and stars, has been migrated to a new Astronomical Art Gallery.

I also prepared an application and submission package for participation in a corporate art gallery program. My inclusion in that program is a long shot as none of the artists in that program are digital artists nor does my artistic style match that of the other artists. However, nothing ventured nothing gained.

The Illustration

The picture I used to illustrate this post is a self portrait taken at Bryce Canyon National Park. This photograph was taken about an hour after sunset. With my camera on a tripod, I set my camera to its slowest ISO speed and the lens aperture to its widest opening. Opening the shutter for a 13 second exposure, I had ample time to amble around to a position in front of the camera after several seconds of exposure had already elapsed. I remained in the field of view for several seconds before exiting the scene. The result was the ghostly effect seen in the photograph.
