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.
