I keep a logbook for every shoot — not the romantic kind, but a plain table: location, hour, light, lens, how many frames, how many kept. After a decade the table has become its own kind of portrait. It knows things about me that I would not have admitted on my own.
It knows, for instance, that my keeper rate doubles in the first hour after sunrise and collapses after lunch. It knows I overshoot reportage and underexpose portraits. None of this is flattering, and all of it is useful. The log does not have opinions about my talent; it only counts.
The notebook does not flatter you. It counts. That is exactly why I trust it more than my memory of the day.
Once a body of work is structured — tagged, timestamped, counted — it stops being only a portfolio and becomes a dataset you can interrogate. Which streets do I return to without deciding to? Which assignments quietly taught me the most? The answers reshape how I plan the next one. Process, written down, becomes method.
I am not arguing that every photographer should keep a spreadsheet. I am arguing that intuition improves faster when you let it check its work against a record. The log is where the two halves of my practice shake hands.
