Development time is, about 1 minute or 1.5 minutes. I was told to keep the development time low and consistent. You may want to read a book by a woman named Bea Nettles called the Photo Cookbook. It has a section about pinhole and ortho film.
If You develop your ortho film for too long you will get a higher contrast neg. It depends on what you want. I am currently using some of the ortho litho film from Freestyle - pre cut into 3.9x4.9 sheets. This is item number #519-44. I use this film for 4x5 work. You can also use Agfa neutol plus diluted 1 to 20 - it is supposed to yield similar results to the dektol. I like neutol as you only have to add water to the premade chemistry. Hope this helps. ----Wendy garfinkeldes...@aol.com
