Below is a time lapse filmed in Aspen, Colorado and pieced together with Adobe CC.
I was planning to shoot this with an interval timer and my Canon 1D mounted on one of my matthews light stands, but I ordered the timer too late, so it didn’t arrive on time. I already knew that iPhone had the capabilities, so I wasn’t too worried, just had to make sure the phone would stay on un-interrupted for 9hrs straight. I tested the phone a couple days prior to the shoot and figured out that I had to set the airplane mode on so that the phone wouldn’t receive any phone calls while filming. The phone had to be plugged for it to last this long, so I brought a super long extension cord to keep it alive.
The footage from iPhone is impressive to say the least and a nice tool in the camera bag or a pocket.
