[Bug 193336] New: Fill Flash tool request

https://bugs.kde.org/show_bug.cgi?id=193336

           Summary: Fill Flash tool request
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: unspecified
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.2.3)
Installed from:    Ubuntu Packages

The no-longer available application BrilliantPhoto had a terrific Fill Flash
enhancement. This enhancement worked as the current Colour -> Auto Correction
-> Equalize worked, however, it modified the image in an uneven fashion. The
darker areas would get full treatment, and the lighter areas would get less
effect, thereby preventing the overexposed appearance.

Unmodified image, with dark area. The image needs fixing.

This is the image after Colour -> Auto Correction -> Equalize

In this image, the darker areas now look acceptable, but the lighter areas are
completely ruined. Had the processing been applied in a scale relative to the
darkness of the particular pixel in question, the entire image would look
acceptable.

I think this is more like "Fill Light" option of Lightroom/Photoshop. Short
description:

Not quite sure what the Fill Light slider is doing? Well, think of it this way
- when you adjust your Exposure setting, Lightroom will tend to make the entire
photo brighter. This may be fine most of the time but it may eventually push
some of your highlight areas to the point where they're clipped and become all
white. If you reach that point and you'd still like to make the photo brighter,
you can resort to the Fill Light slider. This will adjust the midtone areas of
the photo and will, for the most part, leave your extreme highlights alone.
It's a good way to brighten the overall photo without blowing out your
highlight areas.

From: http://www.lightroomkillertips.com/2007/fill-light/

On Linux you can see implementation eg. in Raw Therapee.

That could be, Gilles. In fact, I do want to decrease the lighting ratio as I
want to brighten only the darker areas. I am not looking for any special
effects, the end result should be a photo that looks normal.

It is too bad that the BrilliantPhoto application is no longer available, I
would have loved to post before and after pics from it.

Yes, that seems similar. I will go through the related bugs and comment where
necessary, and I will possibly mark this one as a dupe.

All six of them probably could be merged into one wish for Highlight/Shadows
plugin.

@Mikolaj: I do not think that the actually bugs should be merged, as they are
requesting (slightly) different features. But I do agree that such a plugin
could be a solution to all of them.
