I got a job today at a small photo studio (at the mall). They do family photos, class pictures, Christmas cards ... etc. And they recently (like 2 weeks ago) switched to all-digital. The cameras they use for the sessions are Cannon D60s plus lightroom 2 and CS3.

I'm comfortable with the software, I've never used the C60 outside of a camera shop. Any tips or general advice to make a good impression or avoid looking like too much of a noob?
