I would like to see your best photographs that feature measuring instruments from any period of human history. Your entries must not include people or mannequins. A measuring instrument is a device designed to measure a physical quantity of real-world objects and events, examples being clocks to measure time, scales and balances to measure weight, thermometers to measure temperature and rulers to measure length. The measuring instruments that you show me may be located in museums, buildings of any kind or outdoors in-situ. Colour and monochrome submissions are both permitted. I look forward to seeing your photographs of a wide range of measuring instruments both old and new.
Every photo submitted will be available for the crowd to rate once the submissions period has ended. You can see all the images uploaded to a contest, but will need to rate them to see how they’re ranked once the rating period begins.
Some contests on Photocrowd also have a judge. After the submission period closes the judge chooses their favourite images and writes some image reviews. The crowd and judge results will be announced on the same day.
