Well get me today! I helped a friend get to grips with her Canon camera, she's designated photographer at her daughter's wedding!!!. We found a few useful functions, worked out how to turn off auto flash, and use manual settings. We reviewed long depth of field, aperture priority with +/- EV compensation, changing ISO and in doing so getting her confidence back. At the end of our session in the low lit church she left smiling and thanked me for keeping it all at her level.
PoJT - I foiled a shoplifting pair of teenage oiks from taking leather wallets from the shop display!
Well, you've had a full day of it! A photographer friend told me when I was first starting that she shot a lot in AP mode. Kept her from having to fiddle around so much with Manual mode when there was a lot of action going on.
