Numbers, Numbers, what do you mean?

Answer from my neighbor!

"The numbers between 100 and 150 (in your view finder or info screen) were probably your shutter speed. Put a 1/### and it tells you how long your shutter is open for. So, if it said 100 it was open 1/100th of a second. The shorter it's open the better it can stop the action. If it's open too long it will be fuzzy due to camera shake or the subject moving.

A good rule of thumb is that you can hold 1/mm of the lens. But since your camera has a 1.5x smaller sensor you need to multiply it by 1.5. So, your 35mm lens can probably be hand held at 1/50th of a second assuming your subject is holding still. 1/100+ is a good number for an infant. 1/200 is good for a moving toddler, maybe even more."

I will experiement soon and post my results!!

Thanks for your help neighbor!!!
