5. Now go to FILTER...Blur...Motion Blur. Angle 0°, Distance: 40px.
You should now have a "satin-polished" plate as to the right. The higher the distance you set in step 5, the finer the grain on the metal will be, but be careful not to completely "blur out" the grain.
6. Click on the Layer Styles button at the bottom of the layers palette and add some Drop Shadow - not too much.
What we have done so far is a Photoshop basic - whether we are creating metal, wood, rust etc. We "rough up" the surface using Noise and then smooth it out using Motion Blur. If, for example we had left "Monochromatic" unchecked in Step 4, we would have had a basis for a wood effect.
The remainder of this exercise is, again, basic Photoshop. Having created the plate with its Drop Shadow, we're going to "punch out" holes etc.
