7.1 Motion Control: Initial Setup
7.1.1 Camera Settings
Before we get into how to use the controller let’s review some strategies for getting that perfect
video. Some of this may be obvious so apologies in advance! These are only guidelines and
certain shooting situations will require deviations from these suggestions.
7.1.1.1 Camera Mode
We recommend that your camera be in manual mode. You will want the exposure to be set
explicitly by adjusting the aperture, shutter speed, and ISO manually (NOT set to “Auto”) to
avoid/reduce exposure differences (flicker) from frame to frame. Make sure the shutter speed
isn’t longer than your interval time – otherwise the gear will be moving while you’re still
exposing.
7.1.1.2 ISO
The ISO setting should not be set to “Auto” to avoid exposure differences between frames.
7.1.1.3 Aperture
This depends on the content that you are shooting. To avoid flicker in time lapse applications
you may want to consider a fully manual lens. What does that mean? It is a lens that you can
adjust the aperture on the lens itself (not through the camera).
7.1.1.4 Auto-Focus
Typically you will want auto-focus off to prevent distortion in the final video.
7.1.1.5 Lens
Do not use a circular polarizer lens filter. The change in the angle of light reaching the sensor
can cause unintended color gradients in large solid color areas (the sky is a perfect example).
If your lens has image stabilization be sure to turn it off.
7.1.1.6 Test Pictures
Before you commit to a 1000+ picture time lapse be sure to take test shots at different positions
along your motion profile. The exposure can change significantly from one location to the other
and it may be a fine balance between over and under-exposure. Embrace your camera’s
histogram if you haven’t already.
