I have spent several email messages with Christine about this process and got the chemicals together to begin work. Of course this was last summer, and we have yet to get to experimenting, but now you can see why it struck my attention.
In addition, I purchased her book as a research aid for my classes. It has a great deal of basic information about a wide variety of photo techniques which could be helpful. Simple and straight forward and no I donot get a "kick back".
For some advance workers it may be too basic but it is great to hand to students and have them wander around looking for something fun to try.
