Diagonal lines - in PS, create a new layer, and hit "U" to get to the proper tool set - it may come up as the rectangle tool first - click and hold to see the rest of the tools under that button and you'll see the Line tool - Bingo! At the top you can set the line width, and at the far left, you can see the 2nd section of icons has 3 "boxes" - click the one on the right to "fill pixels". When you hold the Shift key down, you can drag straight up and down, as well as perfect 45 degree angled lines. As far as bump maps, try this excercise (I know, yet ANOTHER excercise...) where you just make a grey square picture (just 512x512) and save it as your "color" image, and then draw white lines, or fill white boxes, and then black lines, and black boxes - save this as your "bump" image. This way you have NO texture in the general color - everything is created by the bump map so you don't have to distinguish what's what. Apply that to a sphere or box and see what it does. You canmake any texture you want just by using different shades of grey, and on the extreme end blacks and whites. If you just turned you copper image above into grayscale and used that it would be far too lumpy and more resemble rust than brushed steel so you'd have to lower the contrast a LOT. Just changing the color image to B&UW is the quickie method, but not necessarily realistic. Actual plates that are copper: (just an idea for you) Try creating an image that is just a truckload of lighter and darker boxes overlapping (make them on different layers) and change their opacity so they even overlap visually. If you just wanna be fast, flatten and save as your bump, then turn it into a copper color. Draw the lines like you want - go nuts with it. Take your brushed copper above and lay it on the top layer (Ctrl+T - stretch it to fit) and change the mode to "Soft Light" so it'll look like brushed copper plates. You can always just apply this to see how it's going to work, and change it/do it differently if you don't like the results - but hopefully you'll have a better understanding of how you can create textures in PS. See how that works for you - I know you're frustrated. I'm kind of caught between giving you exact directions and pointing you in the right direction because I know you want to come up with this on your own (to make it YOUR texture and not someone else's), so maybe this will be a better "point" perhaps? Good luck and happy experimenting- -Lew ;-)
