Exposure display prior to negative conversion

When doing negative conversion, one needs to expose the photo of the negative correctly ("Expose to the right without clipping" as per the official docs). This is easy enough to do, but often exposure needs to be adjusted per frame.


At the moment, the negative conversion process is something like this:

  • find correct exposure

  • shoot frame

  • perform conversion/adjustments to the frame

  • shoot next frame

Shooting the next frame is where the problem starts: C1 automatically applies adjustments from the previous frame (good, thank you), but that leaves the user in the dark about what the exposure was for this frame - C1 only shows the histogram with all the adjustments applied, and the photo has to be reset to check whether the frame was correctly exposed. This breaks the flow and slows down the scanning significantly.

Proposal: add a tool that shows the histogram prior to the conversion, but after some adjustments (base curve, crop, wb - what's needed to be done before clicking the conversion button).

Current workaround

Reset new frame to see the histogram (but this also resets the curve back to Auto, and sometimes I forget that, and waste even more time) 😭

    Hi there, thanks for the message!

    This tool actually does already exist 🙂 It's called "Exposure Evaluation", you will find it in the "Scan" tab of the "Film Negative" workspace, or in the "Tether" tab of the default workspace, usually at the very top. This can also be added to any other tab and workspace, even as a floating tool, like any other tool.

    The tool simply shows a histogram before any adjustments - with the small caveat that it will invert itself when switched to the negative mode. In this case, instead of looking for the right side of this histogram, you should look at the left side.
