One of my tutorials got published yesterday at the photography site CÓMO LA HICE. It is a tutorial about how to turn color images into black and white photos and emulate the Kodak Tri-X 400 film. Again, the tutorial is in Spanish, but the good thing is that it includes a free Photoshop action that you can download and use in any photo you want.
You can take a look at the tutorial HERE. And go to the end of the article to get the link to download the action. Hope you like it.
