Simple and easy tutorial how to transform image ( good for portraits ) into drawing-look-like-image. Ok, we're going to do something like this...

First step: - open image you want to edit and then go to
Image >> Adjustments >> Auto Levels ( or just Shift+Ctrl+L ) to correct some levels
Second step:
- duplicate your first layer and desaturate it to get black and white picture
Image >> Adjustments >> Desaturate ( or Shift+Ctrl+U )
Third step:
- copy desaturated layer, and then invert its colors
Image >> Adjustments >> Invert ( or Ctrl+I )
Now starting the fun part : )
4th step:
- click on third layer ( copy of desaturated layer ), and then change layer mode to Linear Dodge
Final step:
- Copy second layer ( we merged third and second, so now we have only first and second layer )
- Change mode of third layer ( copy of second ) to Multiply
- Blur to add some shading ( third layer ) Filter >> Blur >> Gaussian Blur ( 3.5px )
