Hello there, I am looking at memory for a digital camera at the moment on the internet and I'm getting a bit confused! I don't yet have my digital camera, just wanted to compare proces of memory before I have it. Firstly, do different cameras take different memory or is it standardised? Whats the difference between 'compact flash', 'secure digital', 'SmartMedia' and 'MultiMedia'? Sorry about the questions, I'm new in this game! Thanks!
