EXACTLY. Go to a crafts store and get a few different color sheets of poster board. I have black and white. It doesn't reflect, and allows you to phtograph your models in whatever pose you want without any background except the color of the poster board.Here is a little help from ANOTHER Martin:
Good start on your photography there Guy, but you might want to remove the glass before you try to take pictures of you models with a flash. Or at least put the models in a place away from the glass enclosure for the taking of the pictures.
The reflected flash causes the picture to come out more blueish than it should be. Never use a flash while photographing something in a glass enclosure.
