With Ilford's difficulties and the interruption in availability of\nilfochrome supplies I am starting to see the writing on the wall. I would\nlike to ease into the digital realm by purchasing a scanner for my 2-1/4 and\n4x5 transparencies. Admittedly, I am at the very beginning of the learning\ncurve so I have a few questions.\n1. Since most printers print at 300dpi and to make a 30 inch print I would\nneed 9000dpi but for 4x5 film I would require a scanner with an optical\nresolution capability of 2250 ( 300 x 30 = 9000dpi, 9000dpi divided\nby 4 = 2250 ) ?\n\n2. Any opinions on epsons 4990 vs microtek i900? One sales person at\nCalumet suggested microtek because it is glassless\nand therefore obtains a sharper scan. This thought is also echoed in an\narticle in July's Photo Technique but I haven't heard\nmuch discussion about microtek.
