Two photographers set out to capture the beauty of Yosemite National Park and returned with simply stunning images. Sheldon Neill and Colin Delehanty became friends through Vimeo, where they were inspired by the time-lapse videos of photographers like Terje Sørgjerd. They spent sleepless weeks filming day and night to create this amazing time-lapse video, which pairs their visuals with "Outro" from M83's Hurry Up, We're Dreaming. They describe their adventure in a brief interview and share some of their photographs from Project Yosemite in a gallery below. 

These photographs from the shoot, courtesy of Sheldon Neill and Colin Delehanty, are best viewed full screen. More images are available on their Flickr page.

The Atlantic: How did you get into landscape photography and video?

Colin Delehanty: Mostly I was influenced by my friend Kris. I brought a Canon Rebel XT with me on my first climbing trip to Bishop, CA, and noticed that I was spending more time taking pictures instead of climbing.

Sheldon Neill: I got into Landscape photography nine months ago when I fell in love with a timelapse video called The Mountain by TSO Photography. At that point I made it my goal to eventually shoot and produce a video of similar quality.

What was the inspiration for Project Yosemite?

Delehanty: In 2010, I hiked Half Dome at night just like Sheldon and I had for this video. It was so amazing I wanted to do it again but not alone and with better camera equipment. Sheldon's video Cottonwood Lakes to Mt. Whitney inspired me to follow through on this goal. He convinced me to buy a motion time-lapse dolly from Dynamic Perception so we could both capture motion time-lapses during our trip.

Neill: Six months ago I decided to time-lapse a hiking trip to the summit of Mt. Whitney -- currently the tallest peak in the contiguous United States. It was shortly after that I decided I was going to do something similar, but on a more unique scale that the world can relate to. I wanted to work on the project with someone who shared a similar interest, and that’s when I met Colin Delehanty.

How long did you spend shooting in Yosemite?

We spent around 19 days in Yosemite National park between September and November.

What were some of the challenges of getting these pristine shots?

We had to endure pretty interesting weather conditions, as well as long days with very little sleep, if any. We also had the challenge of lugging heavy gear to a few remote locations, and with the lack of sleep, this increased the demand on our bodies. As we reached November, weather conditions became cold, and really began to test our wills.

What’s next for Project Yosemite?

This last project was a lot of fun so you can expect us to try this again. Follow Sheldon and Colin at Project Yosemite.
