I really want to make a DIY background with the styrofoam and quickrete, but it isn't practical right now with the big move coming up. I hate all those tacky LFS backgrounds, especially when it comes to making pics with the shiny stuff makign the glare off the glass even worse. So, we decided to try something new...
We got heavy duty corrugated cardboard, the kind that feels like plastic and has some sort of coating over it? I bought a huge piece of black material, just plain old cotton, nothing fancy. Actually, I got the end piece of a bolt of material and it was almost 4 yards for less than 6 bucks. We covered the corrugated cardboard with it using staples around the edges to hold the material in place, and then we got out the acrylic craft paints and sponge painted all different colors on it, mostly earth tones like rock and algae colors, with a bit of metallic gold on top. (To sponge paint, you just take any type sponge, dip it in the paint, blot excess out on a newspaper or papertowel, and apply the sponge to the material you want to cover in blotting motions.) You can do colors on top of colors, and it dries really quickly.
The majority of the background is still black, with just a muted hint of color, but it isn't shiny, and it photographs really well. It looks much better than it did before, and if you choose your colors carefully, you can even bring out the coloring in your fish rather than have them blend in with the background.
I will try to get some pics next time we take them off. We kind of spazzed and stuck them on without taking any.
