I use Photoshop, not Gimp, but I believe Gimp has "Curves".
Brightness can be increase by adjusting Curves, and the use of Curves
usually results in a better image.

In one of my earlier posts I mentioned that the background is often
reflected in the object being photographed. That's where that purple
cast comes from on the side of your chuck.
Not a biggie, and it's only a problem with reflective items with
curved sides. Try keeping a block of modeling clay around, and when
you photograph something like this place a strip of clay under the
object so it's off the surface of the background by a half-inch or so,
but out of sight of the camera. That will eliminate or reduce the
reflection. The clay can also be used to position the object.
You are doing much better, BTW.
