I am using Illustrator/Photoshop CS6.
I found a texture pattern online that I really like online. It's a JPG image from an older iPhone background. The problem is that there's a light effect shining on the image. I'd like to back that out to just have the pattern. I've made various attempts with Adobe Illustrator to convert the image to vectors -- I thought maybe I could get it to just trace the lines by telling it there were only 3 colors in the image, but that didn't work out. So in Photoshop, I've tried a few different filters, but I haven't found one that essentially deletes a gradient overlay.
Here's the image I'm wanting to cleanup:
At the end of the day, I'd like a flat version of that graphic that I can tile. A vector render that I can scale would be even better. Any ideas?
Funny... I tried to select the specular highlight and then do Content-Aware delete. It didn't a good enough job, but I was surprised at how close it got!
