So I've been meaning to snag a yellow filter for taking pics of my tank. Then it dawned on me. I have yellow lense sunglasses. These are taken with my iPhone. First is right now. Second is glasses halfway over lens. Final is full coverage. Can't believe how it filters the blue out and actually allows a photo to be taken. They were rush photos, but think I may be able to actually take decent pics of the tank now. Yay!!
