The distance slide turns red when a distance below safety is selected. How ever, depending on light intensity there is a minimum safety distance defined individually for every lamphead. Please note: Distance can be selected in between 0.5m and a viable maximum value defined for each lamphead. The other values and sliders change and display results accordingly. Use the sliders or enter values directly into the corresponding text boxes to select your target values. Choose the desired metric system using the radio buttons. The actual photometric measurements are displayed in this section. Different configuration possibilities exist for different technologies.Ī click on the underlined product name brings you to the product home page. Lamphead ConfigurationĬonfigure the selected lamphead according to your needs. The last dropdown finally selects your lamphead. Select category first, then continue with product group. Usability is best when the phone is in portrait mode and the web site is scaled to this mode (via double click). Its design and usability are optimized for smart phones with touch screen. It also helps to get an idea of the correct camera setup.

However, unlike aperture and shutter speed, a lower ISO speed is almost always desirable, since higher ISO speeds dramatically increase image noise.The ARRI Photometric Calculator is designed to demonstrate the photometric performance of ARRI lampheads at different lamphead setups and distances. Similar to shutter speed, it also correlates 1:1 with how much the exposure increases or decreases. The ISO speed determines how sensitive the camera is to incoming light. It is specified in terms of an f-stop value, which can at times be counterintuitive, because the area of the opening increases as the f-stop decreases. "Shutter speed" and "exposure time" refer to the same concept, where a faster shutter speed means a shorter exposure time.Ī camera's aperture setting controls the area over which light can pass through your camera lens. The shutter speed specifically refers to how long this light is permitted to enter the camera. For example, aperture affects depth of field, shutter speed affects motion blur and ISO speed affects image noise.Ī camera's shutter determines when the camera sensor will be open or closed to incoming light from the camera lens. The key, however, is knowing which trade-offs to make, since each setting also influences other image properties. One can therefore use many combinations of the above three settings to achieve the same exposure.
ISO speed: controls the sensitivity of your camera's sensor to a given amount of light Shutter speed: controls the duration of the exposure An圜 Paula Deen News And RecipesĮ Įach setting controls exposure differently:Īperture: controls the area over which light can enter your camera This calculator can be used to plan long exposures outside a camera's typical range.EV S = EV 100 + log 2(S / 100) where S = desired ISO.EV = log 2(N 2 / t) where N = f-number and t = exposure time in seconds.Output will change as you enter different camera settings.Tweak indivdual settings, watch the others adjust to keep exposure consistent.Enter the camera settings for a known exposure.
