As a member of the directory, 500px users can receive shoot assignments from would-be clients directly (among whom the site counts Google, AirBnb and Lonely Planet) or from the site’s own team of scouts. Directory members are also eligible to have their images included in Adobe’s Stock Premium collection of stock photos, thanks to their recent partnership with the software giant.
Interested photographers can sign up with a simple form that asks them to specify their talents, gear and interests. For instance, one can select whether or not they’re interested in still photography, video or both, as well as their specialities in shooting architecture, weddings, sports or fashion. https://500px.com/
Be sure to have your gear handy though, the site
requires that you list at least one camera (you can add more) but gives the option of reporting additional equipment like 4K and 360°-capable devices.
