Metal texturing is something that is all too often done poorly by simply overlaying photos on top of one another. While this can look alright if done properly, it usually ends up looking like stone or concrete, which does not look or act the way that metal does in real life. We can counteract this by making our own low-contrast base texture, using our own brushes, and also using lots of layers and masks, and finally end up with a hand painted texture that looks and acts much more like real life metal.
