One of the primary factors to achieving footage that looks good is exposure. In practice, exposure is a result of 5 factors. The actual light in a scene, filters that control that light, and a set of three camera controls known as the exposure triangle. The three points of the triangle are aperture, shutter speed or angle, and iso or gain. Overexposure occurs when too much light hits your sensor. Portions of your image that are overexposed appear as pure white, and no detail can be seen or brought back in post production in these areas, unless you happen to be shooting RAW. Underexposure occurs when too little light hits your sensor. Portions of your image that are underexposed are pure black, and no detail can be seen or brought back in post production, again, with the exception of shooting RAW. Getting proper exposure is somewhat subjective. It’s not uncommon for highlights in your scene to be slightly overexposed, or for areas with very little light to be underexposed, but you want to make sure that the main subject of your scene retains the details that you want to show. So, how do we control the 5 factors to get our shots to look exactly like we want them Let’s begin by talking about the exposure triangle. The camera controls that affect exposure are your iris, which controls aperture, shutter speed or angle, which controls how long each frame of video is exposed to light, and gain or iso, which controls the sensitivity of your sensor to light. Each of these controls can have dramatic effects on your final image, So it’s extremely important to have a solid grasp on each control.
