Black and white dropper in levels tool

[marciomendonsa]

 

Dear, could you add the functionality of Black and white dropper, automatic adjustment, in the level tool?

 

Thanks.

The functionality of setting the black and white points is there, in a different way. The eyedroppers would be nice, but the alternate way may be more accurate?

If you hold the Alt key while you drag the black slider, the image will start out black. As soon as anything starts appearing you've located the black point. Similar processing is done with the white slider to find the white point. Hold Alt, and the image starts out white as you drag the slider. When something appears you've found the white point.

Walt, it would be a plus to be beyond this feature, we could count on the dropper and the automatic adjustment

I agree that the droppers would be nice, but the current implementation may be more accurate as it will show the brightest/darkest spots, which might not be where you thought they were. It also illustrates what you're going to lose, which you can't see by simply using the eyedroppers.

Hi Walt and tks for your answer, I asked for a similar feature about 2 years ago as I need not 2 but 3 droppers (white, grey and black) to easily correct color cast on scanned positive films;  your suggestion is welcome and useful (I didn't know this method) and I think it could be a good workaround for marciomendonsa; anyway it would be very useful having the 3 eyedroppers under level adj.  This is my old request:

Complementing the request, there is a request for "automatic adjustment". Please don't forget.

Thanks, Walt. but it would still be interesting to also have that option but its own tool.

Walt, those are destructive tools and they cannot be adjusted after using them. The aim is to click "auto" in non-destructive levels/curves tool panel and refine result that manually in the same go.
