Hi !
This is my first tutorial. I hope it enough clear. If you have any question, please ask!
Made with PSP8, easily translatable (it’s just a work with the layers). The caps are in french cause my soft is in french ^^
Step 1
Crop your image and resize it at 100x100px
Step 2
Duplicate the image twice.
Step 3
On the first layer: Adjustement>Invert
Step 4
On the 2nd duplicated raster: Layer setting: Hue (H)
Copy - Merge (ctrl+shift+c) [See 1st picture] and paste it as a new layer. Hide the 2 duplicated layers
Step 5
Raster 1> Layer adjustement> Hard Light.
Copy-merge (ctrl+shift+c) and paste it as a new layer. Hide the Raster 1
Step 6
Raster 2> Layer adjustement > Soft Light
Copy-merge (ctrl+shift+c) and paste it as a new layer. Hide the Raster 2
Step 7
Raster 3> Adjustement> Brightness and Contrast
And that's finished!
