tutorial #01

{1} start out with your base and prepare it (sharpen if needed etc...). Duplicate it and set it to screen, I set it at 87% but you can adjust it as needed.
I used THIS image.
{2} new adjustment layer > selective colour
reds: -100, 100, 100, 0
yellows: 28, 0, 100, 0
cyans: 100, 0, -100, 0
whites: 100, 0, 5, 0
neutrals: -22, 0, 21, 0
blacks: 0, 0, 0, 22
{3} a new fill layer > #2C0202, set to exclusion at 100%
{4} new adjustment layer > curves
RGB:
input: 150 output: 180
{5} duplicate your base and bring it to the top, set it to luminosity at 100% (change if required)
{6} add this texture...

...and set to multiply at 66% (change if needed)
{7} merge visible layers

{8} image > adjustments > curves (this is optional, it just gives your icon a bit more depth)
RGB:
1st point - input: 68 output: 58
2nd point - input: 188 output: 202
