The second part is getting out and experimenting with the different functions of your camera. Reading and understanding the different variables of the exposure triangle is just part of the battle of mastering exposure. While it may seem incredibly technical, it is what allows the best cinematographers and photographers to capture the creative images that they envision. Mastering the exposure triangle is a fundamental skill necessary for every photographer and cinematographer. It also will break your cinematic shutter speed so be mindful of this adjustment and decide whether it is needed. Keep in mind that a faster shutter speed will entail an adjustment of another exposure variable to let in more light.

However, there is a decent amount of light in the shot and the ISO will probably not need to be increased from around an ISO 500. The ISO setting will depend on the native ISO of the camera. To balance this out and properly expose the shot, the aperture would open up to about an f/2.8 to let in light but maintain some depth of field. Since the shutter speed is increased, the amount of light let in is decreased. Cranking up you shutter speed in this scene to about 1/125th of a second makes movements more crisp and intense with minimal motion blur. Finding a balance within the photography triangle exposure will help properly expose the shot while maintaining the imageвЂ™s quality.ДЄlthough you should follow the 180 degree shutter rule, there are times to bend it. In this scene, the only source of light is coming from the flashlight practicals. LetвЂ™s take a look at an example of a low light shot from the film 1917. This exposure triangle diagram is a great reference to use when determining what settings will allow more light in and what side effects it would entail. To avoid an underexposed shot, youвЂ™ll need to find a balance of all three light exposure variables that properly expose your shot while also achieving the visual look you desire. This could be the case when shooting at night, within closed interior locations, or shooting without much lighting equipment. On the other side of the lighting spectrum, is shooting with a limited amount of light. Photography triangle exposure Exposing with limited light This will allow you to shoot at a wider aperture without overexposing. If the shot is still overexposed given the harsh sunlight, an ND filter would also be utilized to cut down light without adjusting the aperture. Depending on if the shot is still overexposed, the ISO would be set at 500 or less. No Country for Old Men was shot on an ARRICAM Lite with a native ISO of 500. To determine the ISO of this brightly lit shot, we would look at what the native ISO of the camera is. The aperture of this scene would need to be as small as possible to cut down the amount of light let in.

To maintain a cinematic shutter speed when shooting at 24 fps, the shutter speed would be set at 1/48th of a second. LetвЂ™s take a look at what the different variables of the exposure triangle might have been set to in this scene. This video tutorial breaks down the correlation between ISO values and exposure. A higher ISO value such as 1600 makes a cameraвЂ™s sensor more sensitive to light. A lower ISO value such as 50 makes a cameraвЂ™s sensor less sensitive to light. With new technology in DSLR cameras, a cameraвЂ™s sensor can adjust their ISO and sensitivity to light depending on the available light of a shot. In a film camera, ISO refers to a specific film stockвЂ™s sensitivity to light. ISO determines how sensitive a digital cameraвЂ™s sensor is to light. The sensitivity of the cameraвЂ™s sensor to light is determined by our next variable - ISO. Once light passes through the aperture for a specific amount of time determined by the shutter speed, it finally lands on the cameraвЂ™s sensor in a digital camera. For example, if you are shooting at a frame rate of 30 fps, the cinematic shutter speed to shoot at would be 1/60. A cinematic shutter speed captures motion in a way that is most natural to the human eye.
