  1. In lesson 14 you use channel merges, and I'm wondering how come when i follow step by step I go to the channels menu and channel merge is greyed out. Please help. is there a step that must be done that is not shown or is there a file setting? Lost.

  2. I would love to see some more in-depth training on using the Calculations command and Apply Image command. There is a lot of information from the early days of Photoshop that is being lost.

  3. Whew! I think Corey had way too much coffee before recording this video. It was like a roller coaster ride without a destination in sight. He touched on some very interesting parts of the mysterious panels menu, but it was difficult to follow as far as a practical application. The luminous selection was very interesting, but .... Sorry. Not a very good instructional video.Needed more APPLICATION OF TYHE LESSON.

  4. I am having the same issue with channel merge the Scott is having. I know if I shoot black and white it preserves the RGB info. If I greyscale them in post PS wants to relieve me of the information! Should I have shot them as grey scale in order to achieve this result? I need help please!

    • eureka! I freaked out at first thinking PS might not be able to retrieve the color info after discarding, I was wrong. So, grayscale your image first and carry on!
