| − | Here's a neat trick.

| − | The problem you are seeing here is that there is a lot of repetitive variation and contrast in the VALUE of your bricks. This technique will help you remove that value variation, but retain the hue variation.

| − | In your channels, notice that you now have a LIGHTNESS channel. select that channel.

| − | Go to Filters -> Other -> High Pass and run it at something in the 2-5 radius range.

| − | This is useful for removing contrast, but some of that contrast is good to have and you may not want to remove it all. Experiment with keeping a copy of image that hasn't been equalized in this way, and masking contrast back in only where you want it.

| − | This is useful for any source image that has high value contrast (for instance, if part of it is lit very differently than another part). If you've ever offset an image only to see that each edge is vastly different in value, then this is the technique to use at that point in time. You could make a value-equalized version and paint it in only over the seams you are trying to remove, for instance.
