The postproduction tutorials for the 9th edition of Complete Digital Photography use Adobe Lightroom and Photoshop, but if you don’t have a lot of experience with either app, or need a refresher, we’ve posted a page with introductory videos from Ben Long.
Links to all of our support material can be found on the Complete Digital Photography 9th edition support page. If you’re still using an earlier version of the book, we also have dedicated support pages for the 8th edition and the 7th edition.
