Thanks for the guidelines Jason, that pdf is going into my camera bag. I just realized that I use to many different types of films, so I am going to have to commit to one and learn it upside down. I also recommend to anyone that starts with film photography to take a look at JBrunner videos at his web site or in youtube, he makes explanations really easy and really fun. Fun is one of the keys, as he points out in several occasions. Thanks for putting me back on the right track.
