A 180º shutter angle at 24 frames per second means that you need to shoot with a shutter speed of 1/50 second. If you are shooting for a cinematic look, you will want to record at a frame rate of 24 frames per second. To give a ‘normal’ feeling to your video exposure, you will want to use a shutter angle of 180º. Our article on shutter speed and shutter angle explains this in more depth, but let’s recap. You don’t have so much flexibility with your shutter speed because that will be determined by your frame rate. When it comes to shooting video, you will be much more reliant on adjusting your aperture to control your exposure. If you want to shoot with a smaller aperture for a deeper depth of field but need more light to nail your exposure, you can opt for a longer shutter speed and/or a higher ISO. When you shoot stills, you control the exposure of your images by adjusting the aperture, shutter speed and ISO used to capture them. ![]() The values are not quite the same but are very close. T-stops offer a precise measurement of light rather than a measurement of the gap size in the lens relative to its focal length, which is what an ƒ-stop is. These will use T-stops rather than ƒ-stops. A 50mm lens with an aperture of ƒ/8.0 will have an opening measuring 6.25mm.Ī quick word on cinematic lenses. At a focal length of 100mm, the physical size of an ƒ/2.0 aperture will be 50mm. If you’re wondering why the smaller number represents a larger aperture, it’s because ƒ-stops are calculated by the size of the gap in relation to the focal length of the lens. An aperture of ƒ/1.8 is considered large, while an aperture of ƒ/16 is regarded as small. Lenses come with variable apertures that are measured in ƒ-stops. The opposite is true if you choose a smaller aperture: less light will be able to hit your sensor, but you will bring more of your scene into focus. Creatively, a large aperture will afford you a shallow depth of field. From a technical perspective, the larger the aperture you use, the more light will reach your sensor. Light passes through the aperture in your camera’s lens to reach your camera’s sensor, or film if you’re old-school, to create an image.īy adjusting your lens’ aperture, you will have both a technical and a creative impact on your image. ![]() What is aperture?Īperture means ‘hole’, ‘gap’ or ‘opening’. So if you’ve ever wondered ‘What is aperture?’, or indeed anything else related to camera aperture, we’re here to walk you through it. Whether you are shooting stills or video, there are a few fundamentals that you need to know in relation to how your camera and its optics work.
