Feature request regarding Auto-adjust levels
Hello all,
My camera, a Nikon D7200, supports "ADL" which automatically underexposes raw files a little bit if the lighting conditions would blow out the highlights. I like this protection so much that I always leave it on, but of course the brightness levels in my images are a bit more variable now than with the feature disabled.
So one of the things I was really excited about in Capture One is the possibility to perform an "auto-adjust" upon import, this makes sure that the initial levels of my images are more or less correct.
However, there's something I find disturbing about this auto-levels feature, and that is that it will often increase the black level of my images. The side effect of increasing the black level is that it also increases color saturation and I dislike that. I find myself *always* resetting the black level to zero in every image. This very much reduces the usefulness of the auto-levels feature for me.
Therefore my request... Would Phase One please consider enhancing the auto-level feature, giving us the option to leave the black level unchanged?
Kind regards,
Arthur

Have you checked the possibilities in preferences? On the Exposure section of preferences, you can set target levels and you can set "Auto Levels Clipping Thresholds". I have the Shadows in the latter set to 0.00. So it might adjust the black level, but never to the extent of clipping the shadows.

Arthur,
Have you tried a test by taking the same shot with and without ADL to see how Auto-levels treats each of the 2 versions?
I have no idea how ADL works but I would assume that it compresses the dynamic range of the resulting image - which you may not need to do when processing a RAW image in Capture 1.
The other point, in addition to Ian's observation, is that Auto Levels can be run in two modes.
I find the mode that adjusts the RGB values separately is the most valuable in terms of providing optimum results but then I am using a different camera system and no ADL.
Finally it's probably worth mentioning that this is a User to User forum by intent so if you really want to pursue your enhancement request the optimal approach is to create a Support Case, include "Enhancement Request:" in the title with a brief outline of what the request is for and then describe it in more detail (as you have done here) in the body of the text.
HTH.

I am sorry for the very late response in this thread, I was travelling abroad.
In the Exposure section of preferences I have disabled target levels, set the auto-clipping shadows threshold to "0.00" percent and highlights to "0.1" percent. My purpose is simply that the auto-levels determines the white level and nothing else. It should keep the black level as-is.
You know, many real-life images simply don't contain any black. I want the software to respect that instead of artificially raising the black threshold. A RGB color like (10,10,15) is much less saturated than (0,0,5).0 -

ADL does indeed compress the dynamic range in an automatic fashion, but *only* if the camera stores the image as a JPG. To the best of my knowledge, the RAW file is simply stored a little bit underexposed if the camera thinks it needs to protect the highlights. I use the feature simply as a protective measure.[quote="SFA" wrote:

Okay, will do!
