Tutorial: Creating the Che Guevara Effect
Take a picture of yourself or anyone else. Open it.
To get an optimal effect you’ve to mask your face. You don’t have to take special time being very exact. Maybe the fastest way to this us the free selection tool. Make a selection around your face, invert the selection (Select / Invert) and remove the parts.
Again, it is not important to be too exact.
Now choose #aeaeae as FG-Color and press CTRL+, (EDIT / Fill FG) to fill the selection with that color. Press CTRL SHIFT A to deselect.
Now go to (Layer /) Colors / Desaturate. That step is not totally necessary but i helps us to higher the amount of gray tones in the picture.
Next go to: (Layer/) Colors / Threshold and move the little triangle-controls to similar places as I did. Alternatively you could enter 120 to the left and 215 to the right.
You should have good results with it.
You’re done ;) Congratulations!
