Logging rolls while you're actually shooting

You load the roll. You make a great frame. You advance the lever. You make another frame. Somewhere between the third and the eighth, you stop being sure which one had the yellow filter on and which one you metered off the sky. By the time you get scans back eight weeks later, it's gone.

Film Logbook only helps if logging is part of the shot, not a chore you do afterwards. Here's a rhythm that works in the field.

Before you leave the house

Open the app, tap +, and create the roll:

• Film stock (the community database covers most of what you'll find on a shelf — pick from it rather than typing)
• Camera (once you've added your gear once, it's one tap)
• ISO you're actually rating it at, not the box speed
• Expected number of frames

That's the whole setup. Thirty seconds tops. The roll is now Shooting.

If you're pushing or pulling, set the effective ISO now — not when you drop it off at the lab. You'll forget. We've all forgotten.

At each frame: the 10-second log

The goal is a log entry that takes less time than advancing the lever. Film Logbook pre-fills location, timestamp, and the camera you loaded — so in practice you only type three things:

1. Aperture
2. Shutter
3. One word of context (subject, light, or a reminder)

That's it. You do not need to log lens if it hasn't changed, you do not need to log a filter if you haven't swapped it. Film Logbook remembers what you had last.

The bar is: "when I see this frame in four months, will this note tell me what I was thinking?" Usually one word does.

When to add a reference shot

The short answer: when the light is doing something you won't be able to reconstruct from exposure data alone. Snap a quick digital reference with your phone and attach it to the frame.

Situations where a reference shot pays off every time:

• Tricky contrast (deep shade vs. bright highlight in the same frame)
• Mixed light sources (tungsten + daylight, LED + flash)
• You stacked filters you don't normally use
• You were metering off something unusual (a grey card, your hand, the ground, a friend's shirt)

The reference shot is not a composition aid. It's memory insurance.

Handling the weird stuff

Double exposures. Log both frames to the same frame number. Film Logbook keeps them stacked — in the archive you'll see them as one frame with two entries, which is how your eye will remember it anyway.

Metered push/pull that differs per frame. If you rated the roll at 400 but pushed this particular frame to 1600, note it in the frame's notes field, not on the roll. Roll-level ISO is about the chemistry; frame-level notes are about intent.

Filters you forgot to remove. It happens. Log them on the frame where you noticed, and add a note to the previous frames: "yellow filter, forgot to remove." Future-you will be grateful.

Multiple light meters. Pick one and stay with it for the roll. If you switch, note it. The worst logbook is one that pretends to be precise and isn't.

Closing out the roll

When you fire the last frame — or when you give up and rewind a nearly- empty roll — don't leave it sitting in Shooting. Move it to Develop.

Yes, right then. Before you put the camera down.

This is the single change that separates a logbook that actually gets used from one that quietly decays into a graveyard of half-finished rolls. The moment-of-truth is when you advance the film back; if the app is already open to log that last frame, it's one extra tap.

The actual rule

Log like you're leaving a note for a friend who's going to see the scans before you do. Tell them what you were trying to do, not what the meter said. The numbers are on the frame; the reasons aren't.

Everything else — ratings, filters, push/pull — only matters if you log it while the camera is still in your hand. After that, it's archaeology.
