representative of subject matter. most my work is on a white backdrop.

absolutely but check below.

This thing was dumb for me to put in "can see how well my Summicron does." That
was basically meaningless I didn't even state which focal length. (50 by the
way) and it's a fairly standard thing that can be checked out better elseware if
we are not already aware of the lens.
I'm just talking about a general feel of the subject matter and composition
which I picked and the tonality which has half a chance of coming across the waY
I intended. The Dolls I had printed already in the darkroom and here I got a
chance to work from the negative again but this time in the digital realm.
I also Thursday copied that print onto EPN Ektachrome (with my 105 2.8 Nikkor)
so I will compare the apparent resolution and tonality of the two slides myself.
Again: Slides of the same image darkroom verses scan and Photoshop and output. A
whole new ballgame that I will learn from. If the scans don't output well the
copy slides will probably be ok.
