1. Open a simple texture that you want to prepare for making it perfectly seamless.
2. To counter the uneven level of brightness you can simulate a highpass filter in GIMP.
- Duplicate the background layer (the image you want to homogenize).
- On this duplicate use Filter / Blur / Gaussian Blur. The pixels you enter in this filter determine how big the parts (that need to be homogenzied) should be. In this texture the brigher parts are distributed over a bigger part of the image, therefore I take a larger value – around 20-40 px.
- Then do an Colors / Invert
- Colors / Desaturate
- Set the layers mode to “Overlay”
By doing this the too bright parts get a little darker and vice versa – thats how the images brightness is equalized.
Make the effect stronger by just duplicating the “overlay”-layer.
