How to shoot (read once)
- Background: plain white sheet for dark/grey stone, black mat for white stone. Daylight in shade, flash off, no hard shadows.
- Scale: a steel ruler along one edge of the photo. Anything touching the photo edge is ignored.
- Spread photo: particles separated, not touching. Phone flat (green level bubble), 25–40 cm high, no zoom. Washed and surface-dry stone gives the best colour and texture reading.
- Texture and angularity need a close photo: at least 8 px per mm (the app tells you). Shoot the 10–20 mm fraction close up if needed.
- Row pair: 8–15 particles in a straight line. Top photo first, then a front photo at table height (phone upright) with a ruler standing upright. Keep the order.
- Add photos until you have 200+ particles. Weigh the part passing 4.75 mm and enter it in step 4.
Best accuracy: print the calibration mat, put the stones inside its four markers and shoot. The app removes camera tilt and sets the scale itself — no ruler needed.

6 Specification check (lab + camera)
Enter your laboratory results. Rows marked CAMERA are filled from the photos; a lab value you enter replaces the camera value.
Bitumen stripping (coating & stripping test) is done at a different time and has its own tab: Stripping. Its result is picked up in the suitability report below.
Camera vs lab — accuracy check
Enter the lab result next to each camera value above. The Camera vs lab column shows the difference and whether it is within the tolerance. Save each sample to build up your own accuracy record.

3 Camera measurement (optional)
After immersion, drain the stones and spread them, separated, on the printed calibration mat (or a plain blue sheet) in shade, phone flat. On the mat the photo is straightened and the printing is ignored. The camera measures the share of each stone's surface still coated with bitumen.
