So I have this image.
In the image, there are hard changes in color like this.
In paint.net, how can I make those transitions less extreme without losing any of the image quality and tileability?
I know the image looks horrible right now, it is still a work in progress. The image was resized and cropped due to the size limits of uploading. Answers for GIMP, Photoshop, and other programs are also appreciated.
