Re: [APML] Speaking of E100 and Velvia
Hi Robert, I am starting using E200 and as I am reading your message a question
comes to my mind: Does it make a big different to push E200 one stop, or in
other words do I have to always push it at least one stop? By the way I read
your book and is very good. After reading the section on different films for
astrophotography I don't which color film is best suited for this task
considering both negative and slide films. Do you have the answer for this?
Many thanks
