Stabilisation – Method of camera movement control - Tripod, monopod, rig, gimbal, digital in-camera, optical in-camera / lens, etc
Applying consideration to the movement of the camera will go a long way to improving the quality of the images you will capture.
Stabilisation can be as simple as a tripod or monopod, to professional rigs, gimbals and sliders, to full film sets with tracks, dollys, cranes & steadycam body suits where every movement of the camera is carefully considered and controlled.
At the very least I would advise having a tripod as part of your kit, ideally one with a fluid head to minimize camera jerk.
In addition to external stabilisation, a lot of cameras now come with some form of internal stabilization. These take different forms, with varying results.
Examples of these include floating lenses, Optical Image Stabilization (OIS) within the lens, sensor-shift stabilization in body, and digital E-Stabilization.
I’d advise testing the stabilization options to see if the aesthetic created supports your vision. In-camera stabilization is improving all the time and is allowing us to create handheld shots which only a few years ago would have required large professional kits to achive.
