The 2016 Epson International Pano Awards are now open for entries. The Pano Awards began in 2009 and recognizes the best of panoramic photography, (including a VR/360 category since 2011). The prize pool is worth over $60,000, including $25,000 in cash.
Last year's contest had 4,345 entries from 60 countries. Below is last year's Major Open Award Winner by Max Rive of Netherlands:
Here are the top 20 entries for the VR/360 category for 2015.
Notably, the rules are more respectful of photographers' copyright than other competitions. While other contests give the organizers as many rights as an owner to control a submitted image, including selling and sublicensing the image, the Pano Awards rules state that their license is for "marketing and promotional purposes of the event only" (emphasis in the original).
