EDIT: I had started this as a T1i thread, but realized this could apply to any Canon DSLR and thought it might create more posts... So fellow Canon DSLR owners (and anyone else who's got similar camera features)... I'm hoping we can start a thread to share tips on getting the best images out of the camera. Which of these options do you use for most of your shooting? - ISO how do you select ISO (Auto or select an appropriate ISO for the lighting)? - Do you use ISO Expansion (6400/12800)? Do you avoid high ISO at all costs? - What about White Balance (Auto/Presets/Manual)? Do you generally shoot RAW and do PP on your Mac or do you let the camera do some or all of the PP? What in-camera PP settings do you use or avoid and in what situations? In particular: - Picture Style (Contrast, Saturation, Color Tone (hue shift) and Sharpening)? - Noise reductions (high ISO or otherwise) - Peripheral Illumination Correction (on/off) - Auto lighting optimizer (adding detail to shadows) - Highlight Tone Priority (keeping highlights from getting blown-out but limits ISO to 200-3200) What post processing do you find you need to do most often after you've downloaded the pics to your Mac?
