    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!

    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.

    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.

    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.

      i had a little trouble following that one too.. i think the images have to be in grayscale, no layers, and have to be the same pixel dimensions.. then splitting the channels before merging them seems to allow for more interesting final results..

    Good, refreshing. Would enjoy some realistic application.
