Hello Everyone, recently I decided to purchase a DSLR camera to take pictures of my salt water aquarium. The aquarium lights are mostly Blue LED's and White LED's. I have been trying to do a white balance using a white balance card from a local photography shop but the camera keeps telling me that it was unable to do a white balance. I can use the card outside of the fish tank under different lighting and everything works just fine. Am I doing something wrong? Is there a better way to do a white balance. My pictures do not come out nice if on Auto White Balance or even if I chose any of the other pre-set options. The lights are 20,000 Kelvin.
Camera: Nikon D5300
Lens: Nikon 70-300 VR, Micro 85mm VR, and 18-55 VR.
