I just got my Canon 20D (wahoo!) at the weekend and am concentrating on getting used to the 50mm/1.8. Loving it so far! 1. f/2, 1/60s (deliberately overexposed by a stop), ISO-800, natural light only. Post-processing just to remove signs of a cold (snotty nose etc...). 2. f/2.8, 1/1500s, ISO-100. Natural light only. No post-processing. 3. f/2, 1/1500s, ISO-100. Natural light. No post-processing.
