This weekend my husband and I attempted to make a home-made macro studio. It was fun, but actually harder than I was expecting. We did it all for under $10 though, which is the best part. I think the biggest problem was that we didn't have the right kind of lights to use, so we just used flash lights! It worked alright, but it was not ideal. First, we cut holes in three sides of a cardboard box, we covered each side with white tissue paper and put black poster board on the inside to use as a back drop. Check out strobist.com for more detailed information on how to make one.
I took some pictures of my great grandmother's purple glass bowl. She lived in Phoenix, AZ and would turn clear glass purple by leaving it outside in the sun. I don't think they make glass like that anymore! I think the hardest part of using this light box was not getting reflections from the surrounding environment. This one turned out alright though, let me know what you think!
