Coming late to this thread.
I studied photojournalism at Uni. Why? Because my wife bought me a Cannon 550D and I had no idea how to use it. On top of that, my late father left me all his camera gear (also Cannon) and again, I had no idea what it was. To me an F Stop was something from a TV series.... no... wait... that was F Troop, and DOF was something you did with your hat.
The first thing I learnt was to never again use my "auto" setting. You want to be able to control your camera and your shots and not have them controlled for you by some guy in a Chinese factory. The second thing I learnt was to make sure my camera was set up to take "RAW" shots and not JPG. This is for a few reasons:
1. Camera RAW allows you more freedom to correct and adjust your shot post production
2. Camera RAW allows you to imbed info in the final result such as copyright, your details etc.
3. Camera RAW embeds details of the gear you were using including what lens and how it was set up.
So class one, day one was switch to Camera RAW and switch to Manual - even before starting to learn what F stops, Depth of Field ISO settings or any of that other confusing jazz was.
If you are really keen on taking great shots that you control, then I recommend you do the same - switch to manual and change settings to shoot RAW not JPG - you might as well; if you have gone to all the trouble of spending your hard earned on a great camera, make it work for you.
Just a note - I took photojournalism, which is all about telling a story with a camera. Scene / portrait shooting is a very different kettle of fish, but I can confidently say I learnt much (including that taking photojournalism was perhaps not quite what I wanted to achieve!).
Anyway, I am still learning every time I take my camera out so am by no means a pro - or even a semi-pro. More like a sometimes confused ameture who takes the occasional good shot. If I can help in this thread in anyway, that would be great.
