Digital Abstraction
This group is clearly a mixed bag, but in all these works the use of the computer was essential in one way or another. They are based in some cases on the repetition of forms, in some on the manipulation of a photographic image, in one case a multiple scan, and in one case a complete anomaly, a burp of the video card.
In a few cases here, images sizes given are as printed on A3 Plus format artist's paper, which is 13" x 19" (33 x 48.3 cm), with a maximum printable area of about 12 2/3" x 16 1/4" (32.1 x 41.2 cm). However, the master files are generally much larger, and so allow a considerably bigger print.
In some cases, image sizes are provided to give some indication of the quality of definition of the image file. Print sizes are given at 300 pixels per inch, which is the standard resolution for highest-quality digital printing. Most print-on-demand outlets for wall art allow enlargement of the file, when a larger file is needed, by reducing the resolution to as low as 100 pixels per inch, which is three times as large as the 300ppi standard, in both length and width, and nine times the area. For example, one of mine, "Seal", which measures 58" x 58" at 300ppi, would be 174" x 174" at 100ppi, but with a notable difference in quality. This makes no difference for a print not enlarged beyond its original file size at 300ppi.
But my example is too big even at 300ppi to make it clear. If I start with an image of a modest 8" x 10" at 300 ppi (an image file of 2400 x 3000 pixels), it should be fine if I don't enlarge it much bigger than it starts out, maybe up to 12" x 15" (at 200ppi). But if I go to 16" x 20" (at 150ppi), the quality will begin to suffer somewhat, and 24" x 30" (100ppi) is really too much. I think that print-on-demand companies are too willing to sacrifice on quality just to sell a bigger item. (And, let's not forget the framing, whose cost depends on size, and which may cost as much as the print.) The artist can stipulate that his or her works not be enlarged beyond a certain size, but otherwise, the buyer who doesn't know better may get a big print that is less than top-quality.
A few (the "Crucifixion Mandalas") include in their titles some figures that denote (1) the number of repeated sections used to make the image, and (2) their respective principal angles. For example, 22 x 16.4° (which you'd call eleven-sided) consists of 22 sections, each one about 16.4°. (Each set of figures multiplied is 360°, approximately.) The angles actually used in the elaborations were more precise than this - it's really 16.3636° etc. - but with a computer it is at least possible, though painstaking. (Angles like 45°, 30°, and 22.5° are fairly easy.) Still this is much easier and more precise than what I did years ago with the photographic mandalas seen elsewhere on the site, whose prototypes were made entirely by hand. With these I had to print as many as twenty identical prints (and it's not easy to process them so that they are all developed quite the same), cut them precisely, mount them together on a board, then rephotograph the whole in order to make reproductions.
(With respect to the mandalas here, my old essay for the Nicholas Roerich Museum Exhibit - to be found under Artist's Statements - is relevant here.)
