An introduction to and tips for operating video cameras
Initially I conducted some research into the use of cameras and discovered the following essential guidance (see below)stand close to the tripod between two of the legs. Most operators use the technique pictured, that is, the left hand controls the focus, exposure and zoom while the right hand controls camera movement with the tripod handle. There are many variations, for example some operators prefer not to use the handle and instead place their right hand on the camera. Before you begin a move such as a pan or tilt, plan it first. Figure out the best standing position which allows you to complete the whole move comfortably. It is usually much better to finish the shot in a comfortable position than to start comfortably and finish awkwardly. Frame up the end of the shot first and get yourself comfortable, then stretch yourself to get the starting point of the move. The drag setting (AKA resistance or tension) determines how much force you need to excerpt to pan and tilt. The setting you choose depends on several things including the camera weight, the type of shot you are attempting and your personal preferences. Use a lighter setting for close or fast-moving subjects. Use more drag for slow moves, longer zooms, or if you're having difficulty keeping the shot steady. Don't just set the drag and forget about it, think about how different settings might help different shots.To set the brightness and contrast:Switch the camera to color bars.Adjust the viewfinder brightness and contrast until you see a smooth grayscale from peak white to black. You should be able to see a dividing line between each bar.Switch the camera to picture.Check your exposure on a reliable monitor, either by connecting a cable from the camera output or by doing a test record.To set the focus/sharpness (diopter adjustment):The "diopter" is the EVF's eyepiece lens. Adjust this to make the viewfinder image as sharp as possible. This adjustment is usually made either with a ring on the EVF or a sliding button.Choose a subject with plenty of contrast - this makes focus easier.Zoom out wide and focus the camera lens normally.Adjust the diaper until you see the clearest image. If necessary, secure the diaper.
