Nik software (makers of HDR EFEX PRO) has a really good 50% off academic discount on their programs. The discount covers individual programs or the program suite.

Magic Lantern software allows HDR video and FPS control it can also be used for single shot. This software will require a hack of your cameras software, which they take you through. But it opens up your camera to a new level of control. This is not for the weak of heart, however if you are okay with software hacks it's a really cool program.
