*Disclaimer and Introduction*
I was asked by Packt Publishing to write a short, independent review for “Blender Compositing and Post Processing” in exchange for a free copy of the ebook.
Since the Blender Compositing Nodes (next to the Blender VSE, the Video Sequence Editor) are one of my absolute favourite feature in Blender I decided to go for it: I like to use them for post processing video footage/creating looks and love the fact that you can do this with Blender (a very powerful free and open-source 3D etc. solution) on all major platforms/can share your .blends across all those platforms!
So this is my personal, general impression of the “Blender Compositing and Post Processing” ebook while being someone with a more creative mind rather than a technical one:
First thing I noticed is that the ebook comes without DRM (Digital Rights (or as some say “Restriction”)) management and you can download it in four different formats. I went for the .pdf version.
The ebook seems very well structured. It starts off with a condensed overview for all chapters and at the end of each chapter there is a brief summary of what you’ve just read. This allows you to quickly find/read what you are looking for when you need it/to just dive into those topics that you feel not so familiar with. At the end of the ebook there is an Index with the most important keywords/page numbers where to find those topics in the text.
The ebook probably requires some basic Blender knowledge or some familiarity with (3D, video) post production related technical terms/concepts. I think you could use it with not much prior know-how but would need to do some extra research (Wikipedia, Blender Wiki etc.) in order to really understand what it all means/find it useful. More to this at the end of *Content, Approach and Concept*.
*Content, Approach and Concept*
While I was very pleased with the ebook’s structure I was (a bit) disappointed by the fact that this is not what may be called a “workbook”. While there are many visual examples for e.g. how a particular Node works you won’t find more complex examples for Node set-ups to re-create.
For those new to Blender/Nodes a short introduction to the concept: basically compositing in Blender works via “Nodes”, individual sort of filters etc. that allow you to manipulate an image/a series of images in a very specific way while you can combine those filters etc./the order in which they are applied to your 3D renders or footage by connecting those Nodes via sort of wires called “Noodles” and this way create your own very complex set of filters etc. using a very flexible tree like structure. This concept is much more powerful as compared to what you can do in your average image manipulation or video editing programme where you usually only can lay one filter on top of another one and combinations therefore are limited…
My feeling is that a technical minded person or someone with a compositing background/coming from another 3D programme etc. would probably be able to quickly get started with compositing in Blender using this ebook. Someone with a more creative mind who likes/needs to play around with actual examples/set-ups in order to grasp the concepts on a visual or sort of holistic level might need to invest more time and would need to do extra research in order to be able to fully understand the concepts introduced in this ebook.
*Summary and Thoughts*
“Blender Compositing and Post Processing” seems to be a well structured, clearly written ebook that explains the basic concepts involved you need to know in order to get started with using the very powerful free and open-source 3D programme Blender (available for all major platforms, .blends can be shared across all platforms) for post processing either your 3D renders or video footage.
This ebook seems to either requires some prior related technical understanding or the will to research/experiment on your own if you start from scratch. It is not a “workbook” in the sense that you won’t find more complex example Node set-ups to re-create.
I think from a learning point of view (and for the purpose of having fun with the Blender Compositing Nodes/learning them while playing around with them) this ebook could be accessible to an even wider audience with either one or two extra chapters that show how-to re-create specific Node set-ups (like e.g. a toon look, that’s always lots of fun) or the introduction of a practical example section/project for those chapters where appropriate.
I hope this general, personal review was both helpful and describes the ebook in a meaningful and adequate way, thanks for reading, have fun with Blender, the very powerful Compositing Nodes and if you choose so with this ebook!
