I'm using Lightroom to edit my Black & White-photos, but always when I'm resetting a photo, and turning on "black & white", the settings you can see on the screenshot attached, is always on. I don't know why, and I'm always turning them all to 0 in the middle, because I want to edit my photos from scratch, without any pre-made settings, but can someone tell me why Lightroom does it? And it's any settings that I may have changed incorrectly, or what is the reason to this problem?
I'm using Lightroom Classic CC.
Thank you for all answers!
Lightroom evaluates the image as it currently is and sets the sliders accordingly. A quick way to set all sliders to 0 used to double-click on the "Black & White Mix" heading.
There used to be an option Apply Auto Mix When First Converting To Black And White, which you could turn off. But Adobe in its wisdom removed that option in LR 6.7. You could add your constructive opinion to the feature request in the official Adobe feedback forum to add it back: Lightroom CC: "Apply auto tone mix when first converting to black and white" gone | Photoshop Family Customer Community . But in my opinion, it seems unlikely Adobe would do that, given that only 14 people have voted for this in the last two years.
Another workaround is to create a develop preset, which could be useful when converting a large batch of photos to black & white. See here for details on how to do that:
