This is an old thread from 2015 that really helped me with my picture taking. If you scroll down a little bit on this thread there is a picture of how to defuse your lighting that will take the glare off of your coins.
This was a game changer for me back then, and still helps me to this day.
Picture clarity is the most important thing on this site for the experts here to help you. If your coins are too fuzzy or have that bright glare that washes out the details on your coins, it can be frustrating for the picture taker to have to retake photos of there coin, sometimes multiple times.
I hope this helps some of you with your picture taking as it did me.
