How to photograph cast iron for identification
A logo close-up is rarely enough. These views give identifiers—and future you—the evidence needed to compare a casting.

Start with the whole object
Use soft, even light and a plain background. Make one straight-on photograph of the cooking side, one of the underside, and one low side profile. Keep the full rim, handle, spouts, feet, bail, or tabs inside the frame.
Then collect the clues
Move closer only after the overall shape is recorded. Photograph marks both straight on and with light raking across them. Even an unreadable ghost of a letter may become useful when paired with handle shape or heat-ring construction.
- Full top and bottom
- Side profile and rim
- Handle top and underside
- Maker marks, numbers, notches, and gate marks
- Damage, repairs, movement, and lid fit
- One frame with a ruler for scale
Do not clean away the record first
Take the photographs before restoration. Buildup can hide details, but it also documents the condition received. Repeat the same views after cleaning so claims about change remain verifiable.
