A showreel of my best compositing, matte painting, 3d and roto/prep work produced during my VFX degree at The University of Hertfordshire. This includes personal as well as freelance work completed up to the Summer of 2012.
Compositing software typically refers to programs that assemble different types of media, usually visual media, together into a final product. If you are looking for a program for compositing still images, then you should typically consider a 2D compositor for editing photographs or creating illustrations. These programs often have different tools and can create images as either vector or images. You should consider what type of images you want to work with so you can choose the best compositing software for your needs.
