How To Do A Lens Twist

(slow psychedelic instrumental music plays) Okay. We're here at the cabin and we're just gonna set up a time lapse, right by the cabin looking out off into the distance. We have some clouds developing and we just had a storm come through. So it's a good time to set up a time lapse. And this is just to show you that you can do time lapse anywhere. You don't have to go out far away from your house. You can just look out your back door, look out the window and you never know what you're gonna see. Just keep your eyes open. So right now I'm gonna do a lens twist on my time lapse. What that is, is you're locking the aperture so that every time the camera takes a photo, it doesn't send a signal to the lens to open and close the aperture to the correct aperture that you have set electronically through the camera. So if you hold this button down and you look through the lens, you'll see the aperture ring change to 5.6, which is the aperture that I'm setting for this time lapse. When I let go...

, it goes back to wide open, which is 4.5. And... if I hold it down then disconnect the lens from the body just enough so that it's not connected electronically anymore but it's not gonna fall off. So that's important. So now we have it locked at aperture 5.6. It'll help create less flicker in our shot. We won't be able to see the aperture on the camera anymore but the aperture will be at 5.6. We're just gonna have to take a few test photos to make sure the exposure is still correct since the camera can't meter as well without that information anymore. (birds chirping) And that looks pretty good. We're using settings of 5.6, 1 over 200, ISO white balances locked, auto focused stabilizers off. And we can set since this is a storm we have full battery and more than enough memory. So with these clouds, they're moving super fast. I've seen, I see 'em come and go. So I'm gonna use a interval of five seconds and that works just fine for the shutter speed. We're gonna take the camera outta live view. We're just gonna put image review on so we can preview the shot from while it's going. (camera clicks) I'm not too concerned about battery life. So that's not a problem.

I have seen tons of timelapses, but there is no other timelapse film that touches my soul as much as Project Yosemite 1 I never forget the moment when I saw Project Yosemite for the first time! That moment I knew that that’s what I wanna DO! Colin is the reason that I bought my first DSLR! Thank You Alex for getting together with my hero and make this awesome idea happen!

Clear and concise workshop to understand the process of Time-lapse photography Being new to this aspect of photography, I found this workshop informative and directional. If I were to give a critique, it would be regarding equipment choice for the entry level bridging to pro-level for the introductory student. Otherwise, it lays a nice foundation to build from.
