@Mark1616, I am allowed to use a flash and I will try both of your recommendations. When you state 1/50's and 1/100s, is that the Shutter setting? Or?
Yes, that is the shutter speed and it is a pure guess as to what you might get for the correct exposure but you could find that these are not even close to what you will get. Let us know how you get on and post some of your results.
