Brian has given good advice do not rush in. I am at a point where I have been wanting to try this paper, that developer, this film, etc. However the best advice I have been given, is find what is working for me now and stick with it - now that does not mean not using wt or ct papers. The developers could be different - the point is to not introduce to many variables into your work so that if something happens you do/don't like you will know why and can do or not do again.

BTW - I think Tim Rudmans toning book is excellent, but again take it slow.

Shoot more film, print more prints..it's not only fun, but it helps us become better at our craft.

Good Luck
