Before enhancement:

After enhancement:

Open a copy of your image — never work on the original image!
Go to: Tools -> Color Tools -> Levels
Select Auto
Select OK
Go to: Dialogs -> Layers
In the Layers window duplicate your layer ( 2 sheets of paper 4th button from left )
Go back to the image and select
Filters -> Blur -> Selective Gaussian Blur and use the default settings -> click ok
( this part make take a minute depending on image size and how fast your computer is )
When the blur is done go back to the Layers window
In Mode select -> overlay
Adjust the Opacity till you like the result
Back to the image and select
Layer -> Merge down
This makes whites whiter, blacks blacker, greens greener &c. Some images have an almost 3d effect after doing this set of image enhancements.
Also try this with out doing the Gaussian Blur. Every photo is different and you just have to play with each one to get it right.

Nice!
The only problem I’m having is that all my pictures are fairly small, so I can’t use the blur very much because I lose detail.
I should get around to reading the gimp book…

That’s ok, it also works very well with less blur ~3/30 instead of 5/50 in the blur dialog.
Or copy the layer, do the overlay with out any blur.
The blur makes the picture look more 3d. The overlay part is what sharpens things up.
