Effect filters to compensate very common problems

[B.Douille]

The list of filters that are provided by default are more "effect" filter and doesn't really help to fix common issues.

One example is when a photo was taken at extreme positions of a zoom with the largest aperture : Corners are slightly darken.
Applying a correction on contrast/gamma for the whole picture is not applicable as the dark zone is progressive, outside a circle.

Another common issue is over-exposure due to the flash for items and characters close to the camera. In this case, again a progressive filter is required to darken the front scene and keep the background unchanged.

Third in my list of "most frequent" is an error in the light source type. Having a filter to set automatically the right balance for a given, target light type would be helpful.

Note: I searched through the various providers of add-ins. Most of them provides "Effect filter" rather than correction. Maybe these filters exists somewhere, nice if it could be integrated.
