I am planning on going on a cave tour this coming weekend and was hoping someone could help me with the proper settings. I will be visiting a cave that is lit by some type of flood lights. I am not sure what type of lights they will be (tungsten, fluorescent, etc). I own a Nikon D70 and was sure what I should do about setting the white balance. I will also be using a flash, so that adds another wrinkle (I think) to the equation. I once took a similar tour and shot it was color slide film, but all of the caves walls came out very yellow (I am guessing because of the light source the tour was using). I hope this all makes sense. Any help would be greatly appreciated - Thanks!!!
