GIMP Plugin Registry

If you ever wanted an easy way to merge three photos with different exposure settings taken from the same scene together to one image with a well balanced dynamic range - well here is the solution.

Shoot three images of one scene (with a tripod) with an exposure difference of 2-3 between two pictures. The middle one should be taken at the [P] (automatic) setting of your camera, then an over- and an underexposed one.

And be sure not to alter the aperture setting! Solely adjust the shutter speed because otherwise you would get different depth of field values.  read more »

This plugin fakes some kind of DRI effect by enchancing the dark parts of a picture and reducing the light parts. After that procedure it enhances the contrast by using the unsharp masking filter.

Because GIMP has no action recorder till now, i wrote this as a simple batch in python ;-).

I hope, you're like this little thing.

Tested with GIMP 2.6.x. Should be fine in 2.4.x too.

Implement a DRI (Dynamic Range Extension)

Input image with two layers:
Upper layer: Darker Image ((under)exposed for highlights)
Middle layer: Correctly exposed Image
Lower layer: Lighter Image ((over)exposed for shadows)
