camera - Picture size question

[myechophone]

There are so many options available.. any quick reference on which is most optimum? I don't mind the biggest resolution/ size. I "plan" to backup my photos regularly. What do you all use?

16:9 All the time

4:3 offers the widest and top resolution. Form there you can crop to 16:9 or anything you desire.

16:9 cuts off the top and bottom of the sensor...

I use the highest resolution as well. If need other form factor can crop.
