To produce a very high resolution digital >image (400+ megabytes) takes time just to move that amount of data. I don't know much about digital imaging but I've seen the following estimate a few times: a 35mm frame of Velvia has about 64 megabytes of useful information. "Useful" I think referring to how close shades human eye can distinguish. Scanning resolution set somehow according to the size of the grain. So is your figure referring to a bigger format or is this just simply a hard thing to judge? I guess the bottom line is: Are there any standards/agreements currently of what constitutes a digital equivalent of an image on film? Kari
