Welcome to the community
the Black Ham. Hope you enjoy your stay. [excited]
I haven't gone over that tute myself, but i'm going to just say that if he's used the texture properties in the brush palette options in PS7+, you won't have that ability in PS6. You'll simply have to create that texture from an image and add/save (Define) it to your brush palette. From there you can paint with it. But you'll also need to tweak a few more settings than you'd have to in PS7+.
[EDIT]
Ok i just went through the tute, and yes, he's using at least PS7 for that effect. However... it's not completely necessary to use that version for that effect. You have the "Layer Style" filters in PS6 that can create the effect also, very quickly/easily.
Try this:
1) New document, medium to dark grey bg colour.
2) New Layer.
3) Grab a 4px, hard edged brush.
Open the brush palette options and change the "Spacing" for the brush to around 200% or so. Use more if you like.
4) Using black, "spray" the brush over the layer in the manner you want the bullet holes to appear. Don't be afraid to paint more than one row of holes. Be creative.
5) Open the Layer Styles for that layer. Assign the Bevel & Emboss filter. Set the "Direction" to "Down". Click on the "Contour" option as well. From the "Style" menu choose "Out Bevel". Reduce the "Size" to 1 or 2. 1 usually looks ok.
6) Now... under the "Contour" option in the B&E tabs is one called "Texture". Click that one on. The default texture used should suffice. Reduce the "Scale" to -50 (
all the way left), and the "Depth" to -1000 (
all the way left).
7) You can also help the effect by applying a little "Outer Glow" as well. Click that filter on. Change the colour used to black. Set the Blend Mode to Normal. Set the Opacity to 100%. Add 35% Noise. Increase the "Size" till you like the look;
i used 4 for my example.
8) Optionally now, after applying the Layer Style filters... you can 'spread' the holes a little by applying a 1px Gaussian Blur.
Note that for step 8, if you do this to small holes, the effect may well be lost because there's not enough solid colour for the filter effect to be visible on. So generally, step 8 is done more for larger holes.
Here's an example of the effect applied in a similar way to Deelo's.
It should be noted that my image was scaled down a bit so the holes look smaller than they originally were; using a size 4 brush.
Hope that helps.
