The next two photos show the drastic light fall off for anything in shade
while the bright stuff holds together pretty good.
Maybe it's the way I photoshop the pics. Here's a raw scan for anyone who wants to try.
Sorry to dig this old post out again.
I have been doing the same approach as you do (scanning the negative in raw and then converting into B&W later in Photoshop), but I am encountering problem with tuning the contrast.
I used to put a straight away invert layer, into a level adjustment layer for tuning the level of each RBG channel (I just drag the sliders to the ends of the histograms), and finally a black & white layer. In this way I usually have a greyish sort of layer over the photo.
I recently try a different method: invert layer > level adjustment layer to drag sliders of each channel > do a calculation combining the red and blue channel with soft light mixing in order to convert to a new black & white channel. In this way I usually have a high-key image.
Apology in advance if I am a bit off topic, I know I should be discussing the film here, not the Photoshop techniques. As you posted the raw scan, so I had a play around with it. It's interesting to see either of my way can't get the result of the final photo you got (which I like the taste of it). How do you get the contrast just right? Do you mind to share with us your workflow of processing the raw scans into B&W photos and some techniques used in Photoshop?
