If you have queries about the book, or about Photoshop, your best bet is to post a question on the Reader Forum. It only takes a moment to register, and you'll usually get at least one solution the same day.

You can also contact me, Steve Caplin, directly. If your query is a Photoshop issue, though, I'd greatly prefer to deal with it through the Reader Forum so that other members can both learn and weigh in with their suggestions.

If necessary, email me at c@plin.com but if you're after Photoshop advice, the Reader Forum is the best solution.
