Topic: Auto Histogram Equalization ?

would it be possible to get a new function in the batch plugin :

"auto histogram equalization"

in the same way as "auto black white point".

It can save a lot of severely under-exposed or  over-exposed pictures.


Thanks.

Did you try the AutoColorCorrection methods? They do something similar to histogram equalization.

I am not sure what the problem is but try what admin said. I think he is right.

Re: Auto Histogram Equalization ?

AutoColorCorrection performs histogram stretching (Black-white points) and (somewhat excessive) gamma correction. It works well for under-exposed or over-exposed images. It does not work properly for back-lit scenes, with both over-exposed highlights and black shadows.
I still think auto-histogram equalization should be a nice thing, especially if coupled with the opacity slider. Both should be made available in the batch plugin.

Some day, perhaps.... But IA is already a very nice and very powerful tool.
Thank you very much...

The Increase local contrast feature does something similar but usually with better results than histogram equalization, and that is also available in the batch processing plugin.
