Chromasia

While searching the web for some interesting photo blogs a few months back, I came across a site called Chromasia - www.chromasia.com

This site is dedicated to providing tutorials on the finer techniques of Photoshop and covers the following;

Masking

Curves

Luminosity masks

Textures

Portraits

Night Photographs

Black & white

HDR & Lab colour modes

The tutorials are very clearly written and have several short videos to help with understanding the techniques. They are not free of charge but are good quality for money.

I particularly liked the tutorials on luminosity masking, and have produced some really great results from using these techniques. Using the luminosity masks one can quickly select any range of tones within a image and then apply adjustments such as curves or colour only to those selected areas. I only had to follow the in depth instructions once using Photoshop 'Actions' and now I have the selection technique ready at one simple click in 'Actions' palette.

Here's a sample from the tutorial on masking.
