Chapter Five. Basic Image Compositing
Now that we’ve taken a look at a number of different methods to modify a particular sequence of images, we can start to discuss the manipulated combination of multiple sequences. This process, combining two or more image sequences, is the true heart of digital compositing. It requires the use of special operators that are capable of dealing with more than a single input sequence, and so we will refer to these operators as “multisource operators.” As was the case with our discussion of basic image manipulation tools, we will only take an in-depth look at a few of the most important image-combination tools. There are numerous others, and a bit more information on several of them can be found in Appendix A.
