RE: best catalogs for pictures

The following is a simplistic answer to the question explain "adjust the jpg compression ratio". jpg is a compression scheme in that the file size is reduced at the expense of some accuracy of the image. The compression ratio can be controlled. For example an original scanned file of 1 meg can be compressed to 500 kb which is a compression ratio of 2. For an iris photo, the inaccuracy would not be noticeable to almost anyone. If the file were compressed 10 to 1 to 100 kb, most image experts could see some of the inaccuracies. At a compression ratio of 30 to 1, the inaccuracies would be apparent to everyone. Blurred edges are generally one of the easiest inaccuracies to see.
