QUESTIONS

1. The best ISO that we used for me is 400 because we were indoor and it was really bright.
2. My second best photo was the ISO of 3200 because I raised the shutter speed to 1/400.
3. Yes
4. I learned that there is going to be a perfect picture but it might take plenty of tries to accomplish it.
