This last category is a new one for me so what's up is only one part of what will probably be a 3 part series. It's a bit personal - best to just let it flow over you. And my skills for this form (I'm using/learning After Effects) are definitely a work in progress. That said, though I'm not an expert, I've used After Effects to great effect for compositing and retouching, (the names of the particular celebrities will go with me to the grave). It's an area I'm interested in exploring.
