Here your can find a simple instruction how to convert your photos.

Step1:

Find a picture of a beautiful lady.

Ideal pictures will include as few clothes as possible (without being starkers, because that really grosses out Jeasus or something) and plenty of cleavage/leg.

Click on the circle you like (color doesn't matters). Drag it on a naked skin (remember that you can resize it).

Add as much circles as possible.

Step3

- Photoshop

Select the transparency on your dot layer. You can do this either by holding down CMD (or CTRL) and clicking the layer, or by right-clicking the layer and choosing "Select Pixels".

Now invert your selection by either holding down CMD (or CTRL) and SHIFT and then pressing "i", or got to Select > Inverse.
