I tried taking some coral photos at a LFS via my mobile to share with a fellow reefer last week but the lights in the shop just made it impossible. Photos just turned out blue. How to see ? Did some reading up that a red or orange filter can help. I happened to have a Tian Ya plastic filter from my old camera (S$7.50 at local camera shops). Photo of my tank taken with iPhone camera : Photo taken with the filter placed in front of iPhone camera. Closer to actual colors seen
