Hi
In general the images processed with the new option look quite good. Thanks! I
think that the value for WP is a bit too high - burned highlights are probably
even worse than underexposed pixels.
After a lot more testing i can only agree with you...i'll try to find a
smaller threshold for WP.
On the other hand, I am not really sure that having a combined 'Auto BP/WP' is
the right thing. May be seperate options for 'Auto WP or Auto Exposure' and
'Auto BP or Auto Contrast' would be better. This would also simplify the naming.
And you might think about offering the user some keyboard shortcuts or buttons
to do this - I am no really fond of context menus when working on large numbers
of images.
I'm kinda glad about the BP and WP names, cause i think that if we go to
"auto exposure" and "auto contrast", it shouldn't be in curves but on
the sliders instead... I myself, never used curves before, but after all
the curves development, i never use the sliders anymore, curves are
EVERYTHING! :)
I've made a shortcut for myself during testing, as soon as we have some
final here, i'll commit one or two shortcuts for this :)
Just my 10 cents ...
Thanks :)

Hi guys
I've committed auto white/black point calculation to trunk. I hope to
get some testing help from you guys :)
There are 2 values i've been trying to adjust a little, black_threshold
and white_threshold in toolbox.c (line 365 and 366). I'am hoping to find
the magic values that will be good for every image...but it needs
testing to find those...
My idea about it is that a very few pixels should be underexposed and
some pixels should be allowed to be overexposed. It's just an idea i
have, so i'm open for any suggestions...
An other thing is the name... check the context menu in curves...any
suggestions are welcome :)
