Time-lapse flicker occurs when one frame or many frames appear to be under or over exposed in relation to the frames around it when we make our final video compilations. What we end up with is a strobing effects that really subtracts from the enjoyment of the time-lapse video.
This tutorial is about what causes DSLR time-lapse flicker and what we can do to minimize it. Here’s a quick overview:
1. The most common source of time-lapse flicker: Automatic settings
- We can overcome this easily by shooting in full manual mode
2. A secondary source of flicker is a mechanical one: Aperture flicker
- To minimize we can shoot at low f-stops (wider apertures = less exposure variations), however this isn’t always practical
- We can use a manual lens
- We can trick our camera into thinking our automatic lens is manual (lens twist trick)
3. We can also experience flicker from the Shutter: Shutter flicker
- This is easily minimized by shooting at slow shutter speeds ( under 1/100th of a second)
4. Sometimes we need to utilize priority modes for scenes with changing light
- We will get flicker but we can correct with deflickering software, a quick overview of some of the software options out there
- Always cover your camera eyepiece
- Quick introduction to bulb ramping
