No Problem Sally,
I also have some Kindle book suggestions for some good understanding and easy to read about understanding Histograms, Fstop, Shutter speed, and ISO settings for any camera, this guy is a really great author and I suggest anything written by him.
Titles by Al Judge:
Mastering Aperture, Shutter Speed, ISO, and Exposure. Under $10.00
Mastering Histograms, also low priced
Both of these are easy to read and very informative.
