Paper for Exposure Records
I bought some 65lb. white cardstock to make some large format exposure records: the idea is to carry it in the field, record the exposure, filter, etc. using one of the many templates available either in Ansel Adam's books or even better, Ralph Lambrecht's Way Beyond Monochrome. I was going to put the negative in a 8x10 plastic print sleeve and then stick the exposure record in the print sleeve as well; this way, I keep the exposure record with the negative and can look at the negative to see what the picture is.
My questions are such: should I be using acid-free cardstock (3x the price) as I worry about chemical transfer to the negative? Or should I just keep the exposure record next to the file folder as the paper might scratch the negative or affect the negative in some way?
