I am Brand New to this. My current camera is a: Cannon PowerShot S5 IS 8.0 Megapixel 12x Zoom Lens 6.0-72.0 mm I know this camera is good enough for a beginner and I can certainly read the manual, but what might be some pointers to learn about the camera first? Aperture? Auto vs. Portrait? Just looking for the best place to start learning. thanks. Yes, I know to aim at the subject when shooting. lol.
