Tim I preprint 3x5 cards with a little worksheet that I use to calculate my exposures, it includes information about the subject, location, lighting, filters, bellows extension etc. I fill out the card as I make the exposure, and then slip it under the lip of the film holder after exposure. I usually make the same exposure on both sides of the film holder. After processing the first sheet, I have an opportunity to change processing for the second sheet - which I can note on the 3x5 card. Once both negs are processed, they go into 2 of the 4 pockets in an archival negative storage sheet, and the 3x5 card goes into one of the other pockets. The last pocket is either left empty or has a contact print in it. I make notes about how I print the image either on the back side of the 3x5 card, or the back side of the contact sheet. Mark I record exposure and zone placement for every neg into a portable tape recorder so I later know how to process the neg. This also sometimes helps give me hint during the printing process.
