Auto Levels - Choice of modes of operation #3356

Open Beep6581 opened 8 years ago

Beep6581 commented 8 years ago

This is a feature request for adding a choice of modes of operation to the Auto Levels button:

A choice of working space is problematic as the whole Exposure tool works in RGB, so changing the working space of Auto Levels would affect the whole Exposure tool. One solution would be to add an "Auto Levels - Fit Histogram" button in the Lab Adjustments tool. Another solution would be to move the Exposure and Black sliders into a sub-frame and add a working space (RGB or Lab) combobox for that sub-frame only, while the rest of the Exposure panel still works in RGB.

I like this new feature. Right now, Auto-Level is useless for me.

I'd love this feature too, right now Auto Levels is useless for me as well because it's not compatible with working together with DCP profiles that already use a tone curve. Let me propose something a bit more radical as well: Get rid of the current Auto Levels completely and instead use only the new "fit histogram" version with a tone curve that is enabled by default in the camera profile section (Just add a new option "use RT default tone curve" to the camera profile options that can also be deselected of course). I'd use the same tone curve in "perceptual" mode that is already shipped with the DCP profiles made by DCamProf. This way the default look of images coming from different cameras would be somewhat standardized and not dependent on what camera profiles (none, DCP with or without embedded tone curve) are available. This default look would probably also be more similar to the embedded JPG preview than what is produced by current auto levels, which would be less confusing and a better starting point for "Newbies".

This would be great - The current functionality is not very useful to me. either

I fully agree. The current implementation is useless also to me! A "proper" auto-exposure (that only adjust exposure, so no black level adjustment either) would be very useful for me. One of the reasons why I don't like a black-level adjustment is because the current implementation of the black-slider does not actually adjust the black level, it does some other fancy things which look similar to that. A proper (auto-)blacklevel-tool would be very useful as well! (currently I resort to using the raw black point tool, which is very cumbersome)
