1. Open it in The GIMP. 2. Create a new layer. 3. Set its mode to "Overlay" or "Soft Light." (The mode selection is in the Layers dialogue box.) 4. Select the entire layer and fill it with white. 5. Experiment with opacity of the second layer or with colors or gradient fills if you wish. 6. Experiment more. 7. Menu: Image: Flatten. 8. Save.
I've recently discovered this while trying to make pictures taken without a flash in a dark room more or less decent---pick the overlay or soft light layer color appropriately and it's like you've turned on the light in the room. Whee.
I'd been trying to handle it with just the 'levels' and 'curves' tools; I've started experimenting with your technique now as well. Thanks for the tip. The "digital darkroom" means not being able to ask the lab, "hey, can you salvage this frame for me?" -- and my GIMP/Photoshop chops are not at the level I'd like them to be yet.
