I'm not sure I did much. Lynn did a good job of turning things around.

I can understand just wanting an answer. If you post on a photography site (or some site where you're an amateur) at some point, if you've tried and shown that you have thought about it, you might just want an answer.

And it's probably appropriate to give one if the person has made an effort, and is stuck. You can probably still teach them, but along with the answer.
