I just bought a Canon Powershot A75. I have always just taken point and shot 35mm pictures. I am getting ready to go to Disney for a week and need to know what size compactflash I should buy and what setting for my resolution (I think that is what it is called.) The default is large normal. A tech suggested super fine or fine. I have no idea. I just want to take pictures that I can get developed later if I want into regular 4 x6 pictures just like my 35mm. I know I need a bigger memory card but have no idea how big, what kind, etc. I would appreciate any help.
