Hi all, I am a beginner so please bear with me. I have a Sony DSC_P7 digital camera and I'm trying to just get some clear shots so I can edit them in Photoshop. I've turned off Red Eye Redcution and Flash and I'm using a tripod to stablize the image but my photos are so grainy! And flesh tones are always tinged with green. Does anyone know if there are some general rules of thumb for setting up a digital camera? I'm shooting at high-res, 1600x1200. What can I do to get clear shots? Any advice is appreicated.
