Colour Variations in Photoshop
Create Pop Art Style Variations
Creating Andy Warhol Style Images Using the Multiply Blending Mode
The multiply blending mode is one of a range of modes in Photoshop that allow for radical colour transformations.
The cool thing about the multiply blend mode is that in certain circumstances it operates very predictably.
In this image we are applying bright, pure colours to a black and white image with very predictable and easy-to-control results.
The previous colouring video I made on Photoshop Colour Tinting covers colouring techniques that are more flexible than the one shown here.
Download the image used from Fotolia. Or use the technique on one of your own portraits.
Also, using different black and white versions of your image is a worth a try, but generally high contrast black and white provides better results than lower contrast.
