Photography scale cubes
10MM plastic cubes, intended to be used as a size reference in photography.
Photography scale cubes - for specimen photography
These brightly coloured plastic cubes measure 10MM cubed, and are intended for use in photography, to give scale to an object.
We currently only sell these in a packet of ten - they come in random mixed colours which may include white, brown, red, yellow, green, blue and black.
These cubes can be very helpful in a few different fields, including gemstone jewellery, mineral identification, and fossil identification.
While we could use a coin, the Internet is international - many experts live abroad and may not know the size of a 50p, a ruble, a quarter or a yen coin.
A 10MM/1CM cube is as close to universal as we can reasonably get, in my opinion.
The worst item I've ever seen used for scale is a paint roller, in a photograph of minerals - it didn't just look bad, but there are multiple sizes of paint rollers, too. Technically these are often slightly more or less than 10MM, but only by a fraction - typically 9.9MM.
