Master Techniques for realism using postwork [link]
Master Techniques for realism using postwork [link] teaches you how to transform a simple rendered image into a photo realistic one.
To make an image look realistic with some postwork is not that complicated and if you read my tutorial you can see/learn how I do that.
I'm not saying it's the only possible way to do it, it's just the way I paint. Of course there are many ways to make a photo realistic image and every artist over time will develop its own style, techniques and trick but, what you can learn reading this tutorial is still useful for both beginner and advanced artists.
The tutorial is 35 pages long and has a lot of new, easy to learn and useful techniques and many large examples in images. Most of them are at their original size, cropped from a 3000 x 2500 px image so you can see exactly the way I make my artwork.
You are welcome to learn my techniques and use them in your future work.
