I have had many questions regarding photography, how to improve, equipment, etc etc. Whilst I agree with a recent post by Bruce Percy, a certain level of technical understanding is always required. Hence, the reason why I thought I'd pass on a great website I recently stumbled across that gives a fantastic overview of all the technical aspects you need for photography.
It's called Cambridge in Colour and it includes information and guides from everything to basic exposure concepts through to lens corrections, histograms, and stitching. I noticed also a photographically thought-provoking section regarding the human eye.
Anyway, there is plenty for you to peruse so the rest I'll leave to you. There are lots of other sites, but this is one of the best I have seen.
Enjoy.
