To the OP... when you hear these things like that... take special note. There is TONS of cross over between painting (artwork) and photography. It is not to be ignored if you want to become a really good photographer.
There are a ton of books out there that can tell you how the sensor works in your camera or what terms and definitions of things mean... but at the end of the day you might need to know that stuff... but mostly it won't help you be a better photographer...
"Drawing on the right side of the brain" was one that was recommended to me by an artist friend of mine...
There are a lot of resources out there... you won't be able to read everything... so when you do read books follow it up with some practice trying to put what you read into a photo or several photos.
It's not just reading... it's practicing what you read.
For example I read something about lighting and this and that once and it really struck me... so in my back yard I have this bird house... I went out at all different times and hours and weather and took pictures of the same bird house... it wasn't that I wanted pictures of the same birdhouse... it's that I was studying how the different types of light fell across and presented things...
I probably took 500 pictures of that same birdhouse....
