V700 - not sharp?

[Brian Vuillemenot]

The best plane of focus on my 4990 corresponds to the height of the 4X5 film carrier supplied with it.

I recommend scanning at 3200 dpi some high radius sharpening (perhaps 1.8-2.5 pixel (maybe more depending on the image), 30-70% on smart sharpen or unsharp mask) then pulling it down to your desired output resolution (800-1200 dpi) using bicubic sharper filter (there are -much- better filters/methods available, but not without a plugin or external program).
