Hmmm, not sure what this is, but itll help your bushing and colour for sure. I use it a bit.
Begin
1.Open a new document 600x600 and fill it with black. Grab the brush tool and put your colour to white. Start brushing with abstract or grunge brushes in the centre until you get something like this:
Part 12. Do a Hur/Saturation on the shapes. I chose a nice tech blue (my fav ^_^):
Part 23. After you have your chosen colour, go to edit>transform and click perspective. Fiddle around until you get something like so:
Part 34. You should have some pixally bits, so gaussion blur to around this:
Part 45. Right, then edit>fade gaussion blur. Click the blending mode to Darken, like so:
Part 56. Ok its looking well, but lets get some defintion eh? CTRL+Click the layer to select the shape. Contract by 20 and then grab your abstract brush with a brightest colour of the one you chose. I chose the really bright blue. Brush over the selection fairly, like so:
Part 67.Finally, to get them edges to stand out against the centre, go to selection>inverse. Hue/Saturation it to make it darker, like so:
Part 7Your done! Now use that shape for your abstract graphics or your gtnge if you wanna get experimental ;)
Hope that helps for brushing begginers.
