If you’ve ever looked at an archaeological photograph and wondered “how big is that, really?” — you’ve just discovered why photo scale cards exist. They’re a small, simple tool, but they play an outsized role in how Aboriginal cultural heritage sites are recorded, interpreted, and protected across NSW and QLD.
What is a photo scale card?
A photo scale card is a small reference card placed alongside an object or feature before it’s photographed, and a good one does far more than just show size. A typical field card combines several reference elements in one: a black-and-white checkerboard border for measuring scale, a greyscale strip for calibrating exposure and contrast, a bold directional arrow for recording orientation, crosshair registration marks for precise alignment, and a strip of primary colours for true colour calibration. Whether it’s a stone artefact, a scarred tree, an engraving, or a shell midden, the card is included in the frame so that anyone viewing the photograph later — a colleague, a regulator, a future researcher — can accurately judge size, orientation, and true colour without needing to have stood there in person.
Why it matters so much in Aboriginal heritage recording
Recording Aboriginal sites and objects isn’t just about taking a nice photo — it’s about creating a defensible, permanent record that will often outlive the site itself. Photo scale cards matter because they:
- Preserve accurate measurement. Photographs without a scale reference can be badly misleading — a flake that looks palm-sized in a photo might actually be a few centimetres across, or vice versa. The checkerboard scale removes the guesswork.
- Record true orientation. The directional arrow on the card captures which way the object or feature is facing, so orientation isn’t lost or misremembered once you’ve left site.
- Keep colour and exposure accurate. The greyscale strip and colour bars allow photographs to be corrected for true colour and exposure later, which matters when subtle colour differences — staining, patination, pigment — are part of what’s being recorded.
- Support consistent, comparable documentation. When multiple people record sites over months or years — as often happens on larger heritage assessments — a standard, calibrated card ensures every record can be compared like-for-like.
- Underpin legal and regulatory processes. Site recordings often form part of Aboriginal Heritage Impact Permit (AHIP) applications, due diligence assessments, and cultural heritage management plans. Poorly documented photographs can weaken an assessment or require costly re-visits to site.
- Protect cultural information for the long term. Many Aboriginal sites cannot be revisited easily, whether due to access, disturbance, or cultural sensitivities. A well-scaled, well-composed photograph may become the primary — sometimes only — record of that site’s condition and features.
- Demonstrate professional rigour. Correct use of a scale card is one of the clearest markers of a properly trained field recorder, and something assessors and regulators specifically look for in site reports.
In short: a $2 piece of laminated card can be the difference between a heritage record that stands up to scrutiny and one that raises more questions than it answers.
Learning it properly, not just reading about it
This is exactly the kind of skill that’s hard to learn from a slideshow — and it’s why ECHAM Training builds its courses around genuinely interactive, hands-on learning rather than passive content. Our students don’t just read about photo scale cards and site recording standards; they practise setting up shots, positioning cards correctly, and building a compliant site record from the ground up, guided by trainers who do this work in the field every week.
Our trainers — including Len Roberts, Senior Archaeologist with over 30 years of field experience — bring real, current industry practice into every session, whether it’s delivered face-to-face, online, or through our hybrid model. Online components are delivered through an interactive course platform that keeps learners engaged with real scenarios and checks for understanding, rather than static text, while practical skills like site recording are refined face-to-face with direct guidance from experienced archaeologists.
The result is training that reflects what’s actually expected of you in the field — not just the theory of heritage recording, but the practical habits (like never taking a site photo without a scale card) that make the difference between an adequate record and a genuinely useful one.
Train with industry experts
If you’re working toward a career in cultural heritage, archaeology, or land management — or your organisation needs staff trained to a professional standard in site recording — ECHAM Training’s courses are built by practising heritage professionals for the realities of the job.
