Blender Compositing and Post Processing Review


1127OS_Cover_0So I got my hands on this book written by Mythravarun Vepakomma called Blender Compositing and Post Processing. This book is an excellent resource for Blender users at any level.

It is clear and concise for beginners, explains advanced techniques for intermediate users, and is a great reference for experienced users. The first few chapters deal with a lot of critical concepts for beginners in any field of digital graphics including:

  • Bit Depth and Color Modes
  • Layer-blending techniques
  • Color Grading with Bezier curves
  • Masking

In addition to these introductory concepts, Mythravarun also talks about more advanced techniques, such as taking advantage of Blender’s multi-layer render output to cut down on render times, and work nondestructively. These techniques include:

  • Relighting
  • Post-render texture mapping
  • Post-render depth of field
  • Chromatic Aberration and other lens effects

I would highly recommend this book to all blender users, no matter what level of experience. You can get it from Packt Publishing here or from Amazon here


Zoom Blur Filter

Pixelmator has a lot of really cool effects that you can apply to layers called filters. One filter that I’ve found that is very useful is called the zoom blur filter. The zoom blur filter does exactly what it sounds like it should do. It takes the pixels on a given layer and applies a vortex-like zoom effect to it. It is very similar to the radial blur filter in Photoshop when it is set to zoom blur. But, I’ve found that Pixelmator’s zoom blur filter is a bit more robust, and is much more versatile then Photoshop’s radial blur.

Levels and Curves

Within Pixelmator and Photoshop, there are often unused tools called levels and curves adjustments. They are not often used because they have a overwhelming exterior interface which looks much too complicated for the average user. However, the levels and curves adjustments are simple, yet powerful toning tools that can take images from looking static, to vibrant and dynamic.
Basically, They both control contrast, but they are much more robust then your typical contrast slider. They allow you to have much more control over your image then a contrast or brightness slider would.
