Many have written about the disappearance of Isis Corporation and their wonderful Icefields stochastic screening software. One of Icefields advantages was its ability to bypass Photoshop s 30,000 pixel limit (in either width or height) that can become an issue when converting grayscale images to bitmaps at 1,200 or more pixels/inch. Isis hopes to rise like the Phoenix in the future so they don t want older versions of their software distributed for free.
