Channel Mixing, Calculations, and High Pass

Below are a few channel assignments that I did from Chapters 9 and 10 of Deke McClelland's book, Photoshop CS4 Channels & Masks.
























































This is a screen shot I took of one of the masks - I liked it, so here it is!






































In Chapter 12, we worked on advanced calculations and using "high pass". I haven't listed all the steps I took - writing about masking is not easy. Thank goodness Deke wrote a book about it for us!

This first image is actually just a shot of a one of the channels that I liked - I've found that I often like the effects that appear in the channels. :)
