Job 28:28 "And unto man He said:/'Behold, the fear of the Lord, that is wisdom;/And to depart from evil is understanding.' " (C) 2009, Lauren Rothstein.
The cyber objects of art I would sell would be about 900 x 1440 to 1700 x 2338 pixels (full screen), the videos are 640 x 480 (partial screen). This still from VDO Card 08 (above) is about the size of the images in http://netartscrolls.blogspot.com/, a good sample of recent work.
I was taught art by abstract expressionists; I see pinholes and dust as paint drips and thumbprints. The files are high enough resolution for you to correct if you learned art with a post photo editing software aesthetic. Just remember, I own the rights to the work.
The Internet supports at least two art formats: still images and videos. If a virtual reality program could be used for cyber sculpture that would make three.
You could use your old computer to house your art collection as long as it has a slide show program and a media player or you could print the .jpgs for a physical portfolio.
I am trying to find out how much material is needed to accurately represent the work so as to have a no return policy. And yet what is the sense of buying it if you have already seen it in its entirety? I am trying to strike a balance between the two.
I like longer clips because it takes a couple of minutes to adjust to a different outlook. Today's technology handles a one minute clip, tops, uploaded to the Internet using dial-up and takes under an hour to do it. I never tried to download a clip but I do not imagine it would be any faster. I am experimenting with the possibility of a cyber open studio. To sell a digital video one could upload stills and a segment; then burn the clip to CD and physically mail it to the buyer.
