Howto composite over- and under-exposed images

Hello,

is there an easy way to to take shadows from over-exposed image and highlights of under-exposed image and composite them together? (Assuming the two images are exactly the same, e.g. take from tripod or in a quick bracketing sequence.)

I know I could use manual masking of affected areas of one image, however, I would prefer to have GIMP create a mask for 'highlights' automatically (with soft transition to shadows) or even manually on a basis of a transition curve.

Thanks,
Milan

You can do it with layer masks:

..or you can use an automated tool to build up a high dynamic range composite:

Cinepaint 0.20 has a plugin that does a similar thing.

Thanks for the extensive answer, I have been using cinepaint but was not aware about the new plugin.
