Hi Darren. Welcome to POE, you will find a very happy, helpful and varied bunch here. Lots of banter and plenty of forum interaction. Feel free to join in the fun, you will be very welcome
But as to your question, my initial thought is WOW what a huge question! ! ! ! . However there are a lot of very competent photographers on POE as I'm sure you will have noticed if you've had a quick through the site.
A very good, and relatively cheap, start would be to buy one of the 'one off ' magazine publications aimed at Photography Beginners, around £10 mark availalable in most good bookshops / bigger newsagents, Smiths, Menzies etc..
I'm sure you will get a good response from us at POE, we are here to help if possible. But we will need to know a bit more about you and your camera though. What camera do you own? What sort of subjects do you think will be pointing the camera at? This will help the members help you...
Digital is basically free once you have your camera and a couple of memory cards, get 2 or 3, you cannot have enough and they are relatively cheap nowadays. Not like the good old days of film, when it cost money everytime you released the shutter. You can go out and take as many pics as you want, if you fill a card simply put a new one in and carry on. Drop the images onto your computer, reformat the card, preferably in camera, and away you're ready to go again.
So let us have a bit more info, but above all get out there and take pictures. It's the only way. To start with just set the camera to AUTO or PROGRAM and blast away.You will gradually learn by your own mistakes and the help you will get from us. I know from my own short time with the site there is a monumental wealth of experience here. So take some pics, upload them and let us help you.
Look forward to hearing from you again, and seeing some pics
