Hi Shel, It should be that easy but it seems that many operators have set there systems up just so and insist that the output is what will be most beneficial according to their experience, there is no good reason why, it's just my experience locally. Remember many of pre-press bureaus and production houses have been scanning for print long before this digital consumer printing thing came about, old habits die hard I guess. > But if one were to make large prints, 16x20 or larger, wouldn't more ppi > be beneficial?

It's a strange effect, you will have to experiment but from my experience when you scan at a higher resolution than the grain its self the nature of the file changes in that it becomes more lithographic. There ceases to be continuous tone, so adjustment and manipulation becomes more difficult. This is from my experience, hopefully Aaron or someone else similarly experience will step in here? > That may, or may not, be an advantage, depending on the photograph and > effect desired.

In most cases (visible transitions between colours or grays in skies can look pretty bad) however you might want a more lithographic feel in the image too? > You mean I can be even more critical than I am now?!

Aw come on, gotta squeeze every last drop of performance out of your 35mm frames, that's what its all about :-) Cheers, Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://members.ozemail.com.au/~distudio/publications.html - This message is from the Pentax-Discuss Mail List.
