regardless of the background color if it does get "absorbed" i believe it will be minimal light loss. when not using a background thats when the light is just escaping completly out through the glass. so i guess a background is better then no background
Onefish is dead on in regards to the light *escaping* from the tank with no background. At least that's what I've noticed when first setting up my tanks.
I've read that a black background can be more *calming* for certain fish. I don't recall all the fish they mentioned in the article. One of the reasons I chose black (besides the contrast) is that I felt it would be more calming for my pictus. He used to be quite the radical teenager but for now he has settled into behaving like a serene adult.
I use photoshop usually to change the image size of my photo's, But there is a free solution called "Gimp" That will allow you to change the image size.
Here is a link to download the program: GIMP - Downloads
You did your research...good for you! That's a great choice for your tank. I added a bristle to my tank for that very same reason, their small size. I purchased mine as a little 1" albino baby but now he's scaring me as he's a good 4" and it seems I've only had him for two months. What will I do if he ends up being a common plec??
