Response to Scanning negs with dense base

from Ryuji Suzuki (rsuzuki@rs.cncdsl.com)
The biggest complaint is mottled shadows and blacks. It is unlikely that grain is solely responsible for it because D3200 (120) developed in Microphen didn't have as much problem at the same 1600dpi resolution. This D3200 in 35mm is processed in my metol-ascorbate formula tweaked for T-grain films, producing finer grain than Microphen. On prints shadows are as clean as Microphen version at similar magnification.

When I exclude red channel's contribution to the final image, it seems that I lose readable Dmax range without improving the clarity of the shadow.

I have manual control over the black and white points as well as contrast on my scan software, and I can make more shadow to be black by playing with them, but it doesn't make my shadow cleaner.

I tried to wash out the base dye by soaking it in 2% sodium sulfite solution and then rinsing and drying. I'm not sure how much it helped (can't tell by looking or scanning) so it's not a solution.

I put some minimally processed scans from 35mm D3200 on my web server (unlinked from anywhere). I kept rather large images in high JPEG quality so that you can see it better, so they are about 300KB each.

where ? is 1, 2 or 3.

Continuing to seek solutions... besides switching films or the scanner. To me 35mm is an usable toy and I don't want to invest much resource on it :-)

Note: Those pictures were taken with original black Hexar 35mm f/2 at f/2.8 with 1/15 to 1/60 exposures. The bokeh (out-of-focus blur) is very nice, if you haven't figured out what that term means. (I've seen several confused people when Photo Techniques published an article on the topic.)
