gimp

Inspired by the comments to one of my old article, write a short guide to clarify any questions on 'graphic interpolation.

Today I report an interesting site from which I often take inspiration for the writing of my tutorials. The site is PhotoShopTutorials.ws, and as you can easily guess from the name of the domain is a site full of resources for PhotoShop, usable for most of the cases even with Gimp.

Today we see the "Lomo Light Leaks" pack, a collection of effects to add to their photos to make them look old. In pratica si tratta di 71 different images with the effect "flare" or reflex lenses. To apply the effect to the picture you want, simply open the "Light Leak" as a new layer overlaid on the main and change the mode from "Usual" a "Screen". I also recommend you to resize the "Leak" to be applied to the size of the main image.
