I have some questions:
1. what is the difference between EOS and powershot (Canon)
2. For taking picture of moving objects like people during parties & kids, which one is the best camera?
3. what feature in camera I should be looking at for good night shots and less light (60W bulb) indoor pictures?

I have Canon SD990, it used to take good picture but is not doing that anymore..I only use Auto mode..so either it needs servicing or I have changed some settings by mistake. How do I check what is wrong?

Thanks in advance for all the help.
