Photographic register discipline in historic building recording

The photographic register is where a historic building record usually falls over. The images themselves are generally fine. What fails is the document that tells a reader what frame 47 shows, which direction it was taken from, at what scale, on what date and by whom. A conservation officer who cannot reconcile the register to a floor plan will not discharge the condition, and the building may already be gone.

This matters most for a reviewer signing off someone else's record. The register is the one part you can audit without visiting the building, and it is the fastest indicator of whether the rest of the work was done properly.

Why the register is the part that fails

Four failure patterns recur, and all four are avoidable on site rather than in the office.

• Frames with no direction of view, so a photograph of a blocked opening cannot be placed on the plan.
• A numbering sequence that jumps, because deleted frames were not accounted for, leaving a reader to wonder what was removed.
• Scales absent from detail shots, which makes a joint, a moulding profile or a mason's mark unmeasurable.
• Dates and photographer omitted, which breaks the chain of evidence if the record is ever relied on in an enforcement or appeal context.

Each of these is a recording discipline problem. None of them can be fixed after the scaffold comes down.

Choosing the recording level

Historic England's guide to good recording practice sets out four levels, and getting the level right is the reviewer's first check. A record at the wrong level is wrong however well executed.

The condition wording usually names the level, sometimes with a reference to the guide. Where it does not, or where it simply says "photographic survey", agree the level in writing with the conservation officer before mobilising. A Historic Building Recording exercise carried out at Level 2 against a condition that intended Level 3 is a discharge refusal waiting to happen.

Coverage, scales and lighting

Work from a checklist tied to the floor plans. Every space gets at least one general view. Every elevation gets a square-on frame where a viewpoint allows it and an oblique where it does not. Every feature identified in the descriptive text gets a detail frame.

Scales belong in every frame where a dimension matters, which in practice means every internal detail and every structural junction. Use a graduated ranging rod for whole elevations and spaces and a smaller metric scale for details, placed so the scale reads in the plane of the subject rather than angled to it. A north arrow belongs on the drawings rather than in the photographs.

Lighting is where most records lose information. Roof spaces, cellars and blocked openings need supplementary lighting rather than a flash fired from the camera position, because direct flash flattens exactly the raking evidence, tool marks and phasing joints the record exists to capture. Bracket exposures in high contrast interiors and keep the darker frame as well as the balanced one.

Archive to uncompressed TIFF masters with JPEG access copies, and do not sharpen, crop or correct the masters. Historic England's guidance on digital image capture and file storage sets out the practice that archives expect.

Metadata and the register table

The register is a table, and it should be capable of being read on its own. Eight columns cover it.

1. Frame or file number, matching the file name exactly.
2. Subject, in the same terms used in the descriptive text.
3. Location, referenced to a room or space number on the plan.
4. Direction of view, as a compass bearing or a cardinal direction.
5. Scale used, or a note that none was appropriate.
6. Date.
7. Photographer.
8. Notes, for anything a reader would otherwise query.

Then produce a photographic location plan showing every viewpoint as an arrow with its frame number. This single drawing removes most of the questions a conservation officer would otherwise raise, and it is the item most often missing from records submitted for discharge.

Keep the file names and the register numbers identical. A register that numbers frames 1 to 120 while the files are named by camera sequence forces the reader to build a concordance, and reviewers are entitled to refuse on that basis alone.

Drawings that accompany the photographs

At Levels 3 and 4 the photographs are one part of a record that also includes measured drawings: floor plans, sections and elevations at a stated scale, with the phasing shown where the analysis supports it.

The drawings and the photographs have to agree. Room numbering consistent across both. Features shown on the drawing appearing in the register. Any opening identified as blocked in the text visible in a frame. Where an existing survey drawing has been reused, state its source and date, and check it against what is on site rather than assuming it is right.

Where the record is being produced alongside a condition survey for structural reasons, the two documents cover overlapping ground, and our note on condition grading and defect schedules in a structural survey shows where the boundary sits. The photographic disciplines there are similar, as they are in photomontage methodology, where viewpoint recording is equally exacting.

Deposition with the historic environment record

A record that stays on a consultant's server has not been made. Deposition is the point of the exercise, and conditions increasingly say so.

The normal route is a copy to the local Historic Environment Record, held by the county or unitary authority, in the format that HER specifies. Some HERs want digital only, some want a bound paper copy as well, and their requirements differ enough that you should ask before producing the deliverable. Where the work is archaeological in character, an OASIS record should be completed so the project is discoverable. Where the building is of national interest, the Historic England Archive may accept a copy.

Ask three questions of the HER at the start. What file formats and naming conventions do you require. Do you want a paper copy. Is there a deposition fee or a charge for digital ingest. The answers change the budget and the programme.

Discharging the condition first time

Submit a single document with a clear structure: introduction and scope, the recording level and the authority for it, methodology, the building description, the phasing analysis where the level requires it, the register, the photographic location plan, the drawings, the archive and deposition statement, and the images as an appendix or on accompanying media.

Then check four things before it goes. That the level matches the condition. That every frame in the register appears on the location plan. That the HER's format requirements are met. And that the descriptive text and the register use the same names for the same spaces.

Where a Heritage Statement accompanied the original application, read it again before writing the record, because the significance it identified is what the record is supposed to capture. Records that ignore the earlier assessment often photograph the wrong things thoroughly.
