I am just wanting to know how to adjust the pro settings regarding ISO, speed, EV etc. My assumption is WB will have to be adjusted to your tanks spectrum of light to match what your seeing; however, I am a total rookie when it comes to picture taking. I am just trying to get the basics down before I go out and buy a high end DSLR or something on impulse. If there is a sticky regarding this my apaologies. Any pointers when using a phone camera?
