I just heard about the f-stop method of printing B&W, and of the f-stop compensating timer designed for cold light heads.

Any help out there? -- Shel Belinkoff mailto:[EMAIL PROTECTED] - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
