"Ghost" effect in After Effects
I'm shooting a short film where one of the characters is a ghost. It's being shot outdoor in a cemetery, so it's gonna be difficult to make them transparent. I'm thinking of trying to implement some form of "glow" or something, but I'm not sure how to do it beyond rotoscoping/masking the character in all of her scenes.
Check the film riot dudes. They had a tutorial on this topic somehwen.

The standard way to do this without a green screen is use a tripod, keep it static, shoot the background then shoot the action from the same place, in post overlay the action footage and adjust the transparency of the overlay to get the degree of ghostliness you want. You don't need After Effects, any NLE that lets you adjust transparency, and that's pretty much any NLE beyond Windows Movie Maker, can do it.
What Rainer describes is pretty much how this indiegogo trailer was done (with a bit of roto/masking work thrown in).
The slow and painful art of rotoscoping...
What would be easier would be to re-shoot the scene in front of a green screen and compose in AE with the original material. Depending on what you can do or not though...
Rotoscoping? That's sooooooo nineties! There's the Rotobrush in AE. If you have a good separation (contrast) between your victim and the background, it works terrifically.
