@ljmanning I can't tell you exactly what I did. It was one of those things where I tried doing and undoing things and I don't remember exactly all the steps.As far as I do remember, I started with a picture of a tree trunk and I played with contrast and structure to pull up the grain in the wood and then I pulled up saturation to bring out the subtle tones and colours. I added a rusty texture over the wood and then played with blending mode to pull up even more colour. I've probably missed out a few steps but that's what I can reconstruct in my mind.
