To capture an image, there is one thing you absolutely need, which is light. I'm very sure you had of the exposure triangle before. It consists of the aperture which controls the amount of light led into a camera. We also have ISO which controls the gain or amplitude of the light. And then the last mechanism known as the shutter. But light isn't the only thing that shutter affects. It also plays a major role on how motion is captured and not all motion looks the same. So how does an image make use of shutter to control light and motion? Let's get talking. What is shutter speed and how does it work? Along with aperture and ISO shutter speed is part of the exposure triangle. To understand this, let's recap how a camera captures light. Light enters the lens and passes through the aperture and learns on the digital sensor or phone stock to create an image. In between the lens of the sensor is a barrier known as the shutter. The shutter's job is to block light from the sensor. Now the shutter opens for a predetermined amount of time before shutter. This repeats many times per second. The amount of time the shutter is opened is known as the shutter speed, which is usually measured in fractions of a second. For example, a shutter speed of 150 light for 150th of a second. The two direct effects of shutter speed are exposure and motion blur. First, let's talk about exposure. The shutter controls how long the frame is exposed to light. The slower the shutter, the longer the frame is exposed to light, resulting in a brighter image. The faster the shutter, the less light reaches the frame, resulting in a darker image. With the rise of digital camera, came a new kind of shutter. In fact, shutter speed in digital camera is more of a function of the camera sensor. The camera sensor is populated with thousands of receptors called pixels. These are in charge of collecting the light when the images are recorded. But until then, they are always off. When the shutter release button is pressed, the pixel turns on and off for a predetermined amount of time. And this is how shutter speed works on the digital realm. Maybe this could be a lot of information to digest. So, for a complete breakdown for mechanical versus digital shutter, rolling versus global shutter, then the rule of shutter angle, kindly give me a sub as I take time to break them all down for you in my upcoming videos. For now, let's focus primarily on the different visual effects of shutter speed. Now, the function of shutter speed in the exposure process is straightforward. But how it affects motion is a little complicated. Every motion picture contains some amount of motion blur. Faster shutter speed reduces motion blur, while slower shutter speed increases motion blur. The most cinematic shutter speed for a film and video is found using the 180 degree shutter room. When shooting from a video, there are certain look that many image makers are after. You probably heard of cinematic video or the way motion is captured that may make a trial film. Together, all you need to do is follow the 180 degree room. The room explains the relationship between shutter speed and frame rate. Frame rate is the frequency at which consecutive images called frames appear on a display. The 180 degree shutter room says the shutter speed should be double your frame rate. So, if you are shooting 24 frames per second, then your shutter speed should be set to 148th of a second. And this same technique is applied to any other frames you go into. Most cameras don't have 148th, but it's 158th. So, if you are shooting at 24 frames and your camera doesn't give you the option of 148th, but 158th, it's the same. You can go in for 24 to a 158th. But why this ratio? For most cinematic history starting in the late 1920s, the industry standard for film has been 24 frames per second, with a shutter angle at 180 degrees. This remained unchanged for decades. Over time, we have become accustomed to this amount of motion blur, which is just what movies are supposed to look like. It's only when filmmakers deviate from this 180 degree shutter room that we notice the motion blur. So, let's take a look at why cinematographers use various shutter speeds for different effects. Starting with slow shutter speeds, anything set above 180 degrees. As slow shutter speeds create more motion blur, which has a unique storytelling effect. For example, flashbacks. They come to his home in the afternoon looking for his business. They find his wife and kids in the house and decide to wait for sunset. In usual suspect, cinematographer Newton Thomas shot this at 6th frames per second. And wide open shutter when played back at 24 frames receives a motion stutter with lots of smearing. He lets the last Hungarian go. He waits until his wife and kids are in the ground and then he goes after the rest of the mob. John, are you f***ing high? This was also used in Wolf of Wall Street, as Jordan stars Treppenov. Director of photography Rodrigo used the 360 degree shutter angle at 12 frames per second to increase the motion blur of the image. However, if you are shooting at higher frame rates, the 180 degree rule applies less. The Hobbit was famously shot at 48 frames per second, but needed a 270 degree shutter to compensate for a more natural motion blur. Another reason to use a slow shutter speed is for long exposure shots. We've been talking about shutter speed infractions over a second, but long exposure can last for a minute of the time. Picasso experimented with what we call light drawing by using a small light at slow shutter speed. Slow shutter speeds can be a creative way to capture highly stylized shots. On the other hand, eliminating motion blur has its own unique applications. This is done with faster shutter speed and anything below 180 degree. A faster shutter speed reduces the amount of motion blur, making the video appear more hyper realistic. See the photographers use faster shutter speed stylistically to amplify intensity or realism. This is commonly used in scenes with common actions, often coupled with a handheld camera. Yanushikunsky refers to this effect as staccato. He shot his sequences with either a 45 or 90 degree shutter. This extreme lack of blur means we can see individual dead particles in the air, creating a chaotic visual experience. Yanushikunsky also used the shutter for a different effect by offsetting the timing of the shutter so that light hits the frame while it's moving. He was able to create this vertical streaking highlights. As we've discussed, there are certain filmmaking rooms when it comes to using shutter speed to create a cinematic look. However, some of the best cinematographers rig those rooms to create something unique. Mastering shutter speed and exposure triangle as a whole would give you the tools necessary to best tell your story.
