I'm new to photography and would love some feedback about a few questions I have. 1. I'm shooting with a Canon 50D and processing my images with Photoshop CS3. Currently I open my RAW images in Photoshop and make the necessary changes but when I click "save images" I'm getting a tiny jpg that's less than 1MB. What am I doing wrong? I know there's a huge debate over whether it's better to shoot jpgs or RAW data so I'm wondering what are the best post processing steps to get crisp colorful images. 2. When shooting lanscapes how do you decide what to set the aperture, ISO, and shutter speed on? Are their certain formulas that help deciding what the shutter speed should be for a large aperture? Obviously I'm terribly new at this and trying to learn all I can! Thanks for your help!
