I have the 4.5"x7" Rite in the Rain All-Weather Notebooks.
I record every negative taken (easy when one only takes 4 to 6 different images in a day).
On the left side is recorded date location, film, lens, exposure settings, a drawing of the scene, film holder number in a somewhat standard matter.
On the right side are my meter reading, any notes, and what I how I developed the negs. All this info gets transferred to the negatives' film sleeve (paper 4-fold envelopes).
The notebooks also act as a diary of where I have been...but have not much as far as extra infomation (weather, thoughts, plans, etc).
PS...some of my holders (bought used) came with very small holes drilled in the flap that holds the film in - instead of the notches that johnnywalker uses.
