I am taking an online course by Jim White on the 20D camera. I am posting the photos I am submitting for assignments and a few others on this gallery. Please comment if you have other experiences to share with 20D learners. Lesson one is using the 20D White Balance settings including custom white balance. I did the assignment with Berries, Roses, and ivy leaves. Lesson 2 is on ISO and the difference in quality when zoomed in at the different settings.
