Lesson 1. The scanner (Epson Perfection 3200 PHOTO) accepts six frames on a strip. Best to initially cut the negatives to six frames each. The first frame does need to be trimmed as close as all the other frames.
I usually use the Silverfast driver, but the recently installed version of Photoshop Elements doesn’t have it in the menu. No problem, i’ll try the Epson driver. Turns out it will automatically recognizes the frames of the 35 mm. So, i reset the driver settings to se what it would do. In “Auto” mode, it thought i had 12 color transparencies. So i switched to pro mode and toggled to b&w film transparencies. It scanned the images in roughly 400 x 300 pixels. I then ran the contact sheet function and produced a fine 8×10 inch sheet.
Lesson 2: For the quick scan of all 12: Black & white film output to 8 bit greyscale, with the “large” thumbnail option, producing 400 x 300 pixel images for contact sheet.
