Timelapse The Milky Way shines above Lake Tahoe

first_imgThe time-lapse above has been around for a bit so apologies if you’ve seen it already, but if you haven’t you’re in for a treat. It’s a series of images of Lake Tahoe at night. What’s special above the video is not the lake though, it’s the amazingly starry sky above it. It’s a simple video as some of the time-lapses we’ve highlighted before go, but it’s still quite fantastic.The time-lapse was taken with a Canon 5D MKII and a Sigma 24mm f/1.8 lens. An Opteka battery grip was used to get the battery life of the 5D up to a point where it could last all night. The photographer, Justin Majeczky, was even nice enough to reveal the some data about his photographs–they were 30 second exposures at f/1.8 every 35 seconds. He says the ISO was around 1500.AdChoices广告Just to do a little back of the napkin math… It’s a 41 second video and let’s assume it’s at 30 frames per second (it could be less but this will give us a ballpark). That’s 1230 shots. The intervalometer was going off every 35 seconds with makes for 43050 seconds total. Divide that by 60 seconds and then 60 minutes and this was about a 12 hour time-lapse. If the video is at 24 fps then the total time would be more like 9.6 hours which makes more sense given the 9 hours of battery life he mentions in the video’s notes. Anyway, this is why you need an extended battery pack (or a few extra batteries and a lot of patience) if you will be taking time-lapses with long intervals between shots.Bonus: Don’t miss the shooting stars in the first few seconds. You can see one of them in the frame grab below.last_img read more
