On one hand, there are statements like the above - 12,000dpi to extract anything like the full information from a 35mm frame. On the other, there are the "6mp is enough" brigade. I know they are not exclusive. > Back to the practicality of the issue: suppose some D3200 were shot at and > processed to yield 1600ISO or higher then scanned at sufficient resolution to > reveal individual grains (2000dpi+).

Is the ISO scale linear wrt grain size? If so, I assume that to get the same effect from a 25ISO frame you will need to scan at 128,000dpi. mike ----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information
