I am scanning 35mm Black and White negatives using SIlverfast 8.8 with a
plustek scanner. I have a theoretical question.

 

The first thing I do in my work flow is set the resolution that the optimum
seems to be 3200 ppi at the original negative size.  But SIlverfast seems to
suggest using

300ppi for printing. I am in conflict with this idea for the following
reason; When I open up in photoshop cc  I  do my adjustments and the ppi is
still at 3200 but when I go

To print and raise the paper size to say 11 x 14  or 8 x10 the ppi goes down
with the increase therefore reducing my resolution. That is fine as long as
I start high with the

3200. But if I do  what Silverfast suggests I will be down to  like  72ppi
by the time I get to an 8 x 10. I am printing fine art so that seems counter
productive.

 

 

Am I thinking clear on this one?
