Having Problams Turning Out Good Pictures?

Ahhh. you've learned the first lesson.

Photography is all about lighting.

Your lighting source is causing the glare.

Are you using the on-board flash? if so, turn it off.

Then- you might not have sufficient light for a short shutter speed, so put it on a tripod (ideally) or table, or beanbag to stabilize the camera. You can use the timer with a 2 sec delay to avoid hand shake.

Now- your light source needs to be extended. Outdoors on a cloudy day is good. Or, perhaps with a broad open window behind the card, and a white wall reflecting the broad light behind the camera, in front of the card.

you may need to be creative, but the idea here is to get the broadest light source you can.

Morey is correct and his detailed answer is better than mine, but I just want to "add and amplify." The easiest solution is to shoot the pictures outdoors on an overcast day or at least in the shade. Avoid getting your shadow on the cards, though.

Indoors, you can set up two lights on opposite sides of the cards, aimed about about 45 degrees to the cards. Look for a direction where you have minimal glare and try shooting from that vantage point.
