Two questions :)

[teatime0315]

If a negative is underexposed, has it recieved too much light or not enough light?
- I am assuming its "not enough light". Correct me if I am wrong.

What is the difference between digital and optical zoom?
- I know the differences ... but I can't explain it.

I was wondering if you guys could help me out a bit.
Thanks in advance

1: Not enough light.

2: Optical zoom is exactly that: You use the camera's optics to increase detail at the expense of a smaller field of view. Digital zoom basically just means you're making the pixels larger. You might as well change the size in Photoshop.
