My dad's dead, but thanks.

I know you didn't bust his picture, but you could have worded what you said a little differently so you didn't sound so condencending. Like maybe saying: "Hey man, check this out, there's a feature on DSLR's that allows you to compensate your picture's white balance, for different types of lighting."

All I'm saying is DSLR's are complicated, and not everyone knows how to adjust white balance right off the bat, so try to be a little more helpful.
