Forensic photography is a photography genre and a branch of forensic science: the art of producing an accurate reproduction of a crime scene (Wikidata Q2918100). I am not a crime-scene tech. I am the first uniform on a lot of Third Shift calls in Columbus. My job with a camera is narrower and more perishable: freeze the room before EMS moves the chair, before rain takes the glass, before a well-meaning neighbor “tidies.”
What I inherited
Alphonse Bertillon (1853–1914), a French police officer and anthropometrist at the Prefecture of Police of Paris, is the ancestor I actually respect. He didn’t invent “taking a picture of a crime.” He invented a system: metric photography, standardized viewpoints, a body of measurements that could be compared later by someone who wasn’t there. He died in the 16th arrondissement in 1914. The Getty holds work under his name. I cite him because patrol officers still fail the thing he solved — we shoot what looks dramatic instead of what can be reconstructed.

Chain of custody is not a slogan
A chain of custody is a legal concept (Wikidata Q738898): documentation of how an item — or an attribute of an item — is transferred, monitored, and controlled as it moves. It is a subclass of documentation, of chronology, and of evidence. It sits next to provenance. A JPEG sitting in my camera roll with no note is an orphan. An orphan cannot testify.
On a good night the chain for a patrol photo looks like this:
- Create. Camera clock set to radio time before the shift. I check it against dispatch when I log on. If the clock is wrong, every later timestamp is a defense exhibit against me.
- Label in the frame. A card, a glove wrapper, my notebook page with date / CAD / my badge — something that exists in the photograph, not only in a filename I’ll rename later.
- Transfer. Offload to the report system before I go 10-42. Not “in the morning.” Morning is when cards get lost in cupholders.
- Restrict. Personal phone is not a backup. Personal phone is a leak. I have seen a well-meant text become a Brady problem.
- Account. If I delete a bad frame, I say so in the supplement: “three additional exposures discarded for motion blur; files not retained.” Silence reads as concealment.
I told Fernando the same thing about a cash drawer: count it like evidence, or don’t pretend the count means anything. Different job, same chain. See also: chain of custody.
The twelve-shot minimum I actually run
Television wants the overhead God-shot. I get a parking lot, sodium vapor, and ninety seconds before the fire crew needs the doorway. This is the sequence I can finish on a cold sidewalk on the Near East Side. It is not a lab protocol. It is a patrol floor.
| # | Shot | Why it exists | Failure mode |
|---|---|---|---|
| 1 | Approach — from the direction of arrival, whole façade or lot. | Establishes how I entered and what a civilian would have seen. | Zooming in. You lose the mailbox, the camera, the witness’s car. |
| 2–5 | Four corners of the room / four sides of the vehicle. Overlap 30%. | Lets someone later build a panorama without me. | Standing in one spot and pivoting. Parallax lies. |
| 6 | Floor / ground, from waist height, looking down the long axis. | Blood, glass, casings, phone. Gravity is a witness. | Shooting only at eye level. Most evidence is not at eye level. |
| 7 | Ceiling / overhead (one frame). | Spray, holes, a camera you will otherwise miss. | Forgetting it. I forgot it for six months as a rookie. |
| 8–9 | Mid-range: object in context (door + lock; table + bottle). | Connects the close-up to the room. | Jumping straight to the close-up. Courts hate orphans. |
| 10 | Close-up with a scale in frame (dollar bill if that’s what you have). | Size without a ruler is a guess. | Using a coin and then not saying which coin. |
| 11 | Close-up without the scale. | Shows the surface you just covered. | Only shooting with the scale — then the scale is accused of hiding a mark. |
| 12 | ID slate: notebook page with CAD, date, my name, in the same light. | Binds the set. Bertillon would have made me do this twice. | Writing the slate later, in different light, in the car. |

What I do not photograph
Victims in states that don’t serve the report. Bystanders’ children. The inside of a wallet I already inventoried in writing. Anything I would not want read into a record at 09:00 in front of a family. The camera is not a trophy case. Le Guin wrote that the revolution begins in the imagining of a different kind of person — I’ll settle for a different kind of file.

The same overlap rule is how I shoot the Short North off duty — four façades, 30% overlap, a slate with the date. See Short North Studies. Cover: Field File 21.
Neighbor — different beat, same chain
When I answered Fernando on cash-handling, I meant this page. Count it like you will have to reconstruct it. Carolyn’s retail “shed to protect the landing” is the same load-shed I run on a radio net. Different uniforms.
