Even brightness in texture


Question

I have a floor tile texture I want to use in my bathroom Sketchup/Unity model (Its a photo I've taken of the actual tile).

I have tried these two tutorials and none of them reduces the uneven brightness and they also remove alot of detail from the texture

This is my texture enter image description here

If i offset the image you can clearly see the problem enter image description here

Do you guys have any ideas on how to attack the problem?

I found this tutorial, http://www.gamasutra.com/view/feature/131482/the_power_of_the_high_pass_filter.php

And I experimented some more with high pass filter only, I got this result which im pretty happy with

Looks like this in Unity (Needs alot of work on lighting) enter image description here

Update: I tried Keavon's method when I was working on this, revisted the method and got this result. below is the high pass filter method for comparison

I would add an adjustment level to the tile and then start painting a mask on the levels layer. Then select both of those layers (the tile, and adjustment) right click and convert to smart object. Then you transform it down and copy it so you can see how it looks edge to edge. You can then tweak this in almost realtime (after every save of the smart object) by having both the smart object open and then 4 tile pattern.

Mostly because you should do this on your own; You'll find a water mark on my attempt below.

Over all this will take a bit of time to get right.

Stone Tile

Settings

You can see my mask here and layers for the single tile. I also added a black and white adjustment because there was some color variation in the stone.

Good Luck!
