: Gradient Brightness I'm not particularly experienced in graphic design, so maybe there's an easy way to do this that I just haven't noticed, but... I have a layered PNG image in Gimp. It's

Basically involves making your selection, creating a channel, applying gradient to your selection in the channel and then applying it back to your image.

User ofnuts gives a detailed answer on gimpforums.com/thread-change-brightness-contrast-for-part-of-image

Method 1: create a selection with a gradient:


Create the rectangle selection on your layer
Open the Channels list (Windows/Dockable dialogs/Channels)
Click the "New channel" icon at bottom, and initialize to 100% opacity
Your canvas fills with black, with the "marching ants" still marking your selection
Fill the selection with a black to white gradient (white is replaced by transparency, so the parts of the image that appear are
those that will be selected in the end, in proportion to their
visibility)
Right-click the channel, and "Channel to selection"
Click the visibility icon of your channel (makes is invisible, so you should now see you full image)
The selection looks too small (half the height): this is normal, the ants are really traveling the 50% selection line so they only show
the part where pixels are more than 50% selected.
In the Layers list, select your Layer (if you omit this, you'll be editing you channel)
Play with Brightness/Contrast

You can use the dodge/burn brushes but you can also set a layer style to dodge/burn, allowing you to make a shape layer over the object you want to alter rather than having to worry about the cumulative effect of the dodge/burn brush tools.

Try reducing Opacity of Gradient, which will help in reducing its intensity and in-turn helping out the problem.

Looks like I found something that will help my particular situation. The Dodge/Burn tool. I set it to Burn and Midtones and used a fuzzy circle brush. It feels very much like painting a shadow on the object. The only catch is that it's cumulative so one has to use as few strokes of the brush as possible or it'll get too burned too fast.
