It’s 20th shot already 😉 I hope you enjoy this project. This week I was again in Wroclaw for a one day shot and it’s one shot from that day. I love that city because of the amount of really beautiful locations. So, check out the shot and then read a little how-to below 😉
This is a shot from my 52 Timelapse Project. You can check out the details of the project or full list of the shots.
As you can see, this is a slider shot using a rack focus technique (it’s when you are changing your focus point during the shot). But how to pull that in a timelapse shot?
Rack focus technique
I planned to use a mobile app from Panasonic to change the focus, however it turned out it won’t work with a shutter cable attached to the camera. As usually, I had to improvise, so I’ve decided to change the focus manually. I set the interval to 3 seconds to have some time to rotate the focus ring. I would prefer a little bit slower change, but still it’s pretty smooth 🙂
If you follow my blog you probably know from this article how to achieve long shutter speed during the sunlight. However, here we combine a shallow depth of field with a long exposure time! To do that I had to use really strong ND filter. I combined two filters: ND1000 and ND8, which gives me 13 stops darker image (equivalent of ND8000). This let me shoot at f/1.2 to get shallow depth of field.
All the camera settings were as follows:
- Shutter speed 0.5″
- f/1.2 (speedbooster value, f/1.8 lens)
- ISO 320
- Sigma 18-35 @24mm
- ND1000 and ND8 screwed together on the lens
There is one interesting thing I’ve added in post – tilt (vertical) movement. That’s I think the only post production movement I like to use, because it doesn’t look totally fake.
The idea is simple. You deliver video in 16:9 or even wider aspect ratio. Your camera sensor is 4:3 or 3:2, which means it’s higher than your final video. In video mode, your camera just doesn’t use those pixels, which are over and below 16:9 frame. In photo mode you usually shoot with your full sensor, so you can mess with it in post 😉
So, I’ve just added two simple key frames to get this movement. It gives me fake 2 axis movement in my shot.
I love to experiment with timelapses and that’s one of those experiments. What’s yours timelapse experiments? Let me know in the comments and share that on Facebook group: https://www.facebook.com/groups/timelapse.hyperlapse/
