Just a small tutorial to fix underexposed pics with GIMP.

My under-exposed pic..
DSC_0491_filtered.jpg


Open the pic with GIMP 2.2
if you don't see the "Layers" window around.. you need to bring it out.
Select "Dialogs" -> "Layers" or press "Ctrl L" to get it out.

click on the 'Duplicate' icon (circled in red) see picture below.
You should see a duplicate picture layer called 'Background copy'

Click on the words "background copy" to hilight it.

Next click on the drop down box for "Mode: Normal" (circled in blue) and select "Screen" (boxed in red)

finally, Select "Layer"->"Merge Down" and save your picture.

results:

If you find it too bright, you can adjust the intensity of 'brightening' by adjust the 'Opacity' below the "Mode:" box.

For mild (note the word mild) over exposure, you can try to set the blending Mode to Multiply instead of Screen. For most overexposed pics, the details are lost and cannot be recovered most of the time (unless you're shooting raw).

Hope this helps to promote new users to GIMP. I'm still in the process of discovering more of GIMP's features.
 

Thanks for contributing. Gimp is really a cool programme - a power pact freeware.
 

no prob..but seems like GIMP or freeware isn't really popular in here.
 

Interesting.... Well, I guess they prefer PS... But I am trying to learn how to use GIMP... Sad to say there seem to be a lack of tips/tutorials on GIMP.
 

Oohhh, this cat. Cute, maybe I can adopt it :)

Hi, I teach PS at advanced level, but would recommend GIMP to anyone!! It's slow, it isn't anywhere near as 'pro' as PS but with patience, trial and error, and lots of practice can do a lot that PS can, for free, and is certainly more powerful than some other commercial software. :)

My recommendation for anyone who wants to learn to use GIMP,but can't afford PS would be to learn PS if you can get hold of a trial copy and then download the GIMP and learn to use the same techniques in it. ;)
