There was an event recently at the Apple Store in Montreal and Unsplash showcased my photo in a huge 60x40" frame and then shared a photo of it through Twitter. I'm not a professional photographer but it made my day to see my photo displayed and enjoyed by so many people.
While I don't usually toot my own horn, pardon me while I do just that here.

"Unsplash x Apple Inc. Partnership in Montreal. Last night, we got to feature some of Unsplash's photographs that were shot on an iPhone. The photographs were super awesome, and we received lots of love 😍 Thank you Apple and everyone that came out to support us."
