Sounds like it was a fun class! If you still have them, and a digital camera with a macro lens, you'll be surprised how much better result (actual resolved resolution versus MP "resolution") you'll get with than using a scanner. If I had to guess as why you stopped at 2MP, it was probably a mixture of diminishing returns in terms of extra resolving power and size. Idk when you took them, but I imagine size was also a consideration. A 2MP uncompressed tiff (which I imagine is what the scanner gave you) is ~5MB. Now, you could drop that down to ~1.6 if you could save them as single channel rather than RGB. This is also where the optimal conditions come in (motion blur, camera shake, exposure, and how it was developed).
