Hi everyone! This is my 1st post here on the forums. Hope its the begining of a posting frenzy and my new found hobby becomes a passion in life for me. Well my story is this... I had a few things laying about I wanted to sell on eBay and so I took it upon myself to buy a digital camera. Well I went down to my local computer store and the guy recommended me some obscure branded £50 silvery thing. "Takes a good snap and its dirt cheap too!". Erm I got sold a turkey. This darn thing couldnt even focus properly. Anyway I took it back and had a word or 3 with my good friend Google. Anyway I decided upon a Canon EOS 350d or a Digital rebel XT as is known in USA. Wow! I love it. Erm well I love the autofocus at least. Ok dont laugh I'm getting there....Things I get and dont get are as follows, please help me out if you can? ISO -- keep it low and I dont get the grainy pics? WB -- changes the pic from a warmer yellower colour to a cool bluer. I tend to just keep this one on automatic unless taking pics under tungsten indoors. Appature/Shutter speed - I still dont get the F stops and the rest of it, anyone have a quickie explaination? Sorry Also I shall be going Greece shortly and need recommendations on a reasonably priced lens and a macro lens. Also if possible the best place to buy them. Sorry its question overload but im a newbie and im hence allowed!
