Ok, I'll give both sugestions a try. Thanks!
Well few angles to approach it. Photography is painting with light, so first and foremost a good study into light mechanics is a must. There is a ton of math formulas involved if you wish to go down that path but its not necessary beyond some very basics. Then there is the glare, reflection and depth of detail path and other still like bringing out hidden details that is not seen. Each of those areas deserve full study and they complement the other greatly.
