Re: A column on white point

Dean Wilmot

Hi Dan,

Forgive me if this is a basic question esp for this group.

Where in your books does it talk about the best method for setting the black and white points? (for colour and especially B&W images) (and for adjusting mid-tones).

Im starting to use the Howtek 4500 drum scanner I bought last year alot more now and although I've been using a technique recommended by Image Science from the The Fundamentals of Digital e-Book ( section attached) I was wondering though if this is really the best method?

Thanks again

Certainly. All posts to this list should be considered in the public domain. Images, no, but text, yes.
