Exposure time: 1/6 sec (0.16666666666667) F-number: f/16: ISO speed rating: 200: Date and time of data generation: 12:34, 20 August 2014: Lens focal length: 60 mm: Pixel composition: RGB: Orientation: Normal: Horizontal resolution: 150 dpi: Vertical resolution: 150 dpi: Software used: Adobe Photoshop CS6 (Windows) File change date and time: 13: ...
With ISO 200, set it to 1/200 or 1/250 second. With ISO 400, set it to 1/400 or 1/500 second. As with other light readings, shutter speed can be changed as long as the f-number is altered to compensate, e.g. 1/250 second at f /8 gives equivalent exposure to 1/125 second at f /11. Generally, the adjustment is done such that for each step in ...
On a sunny day at ISO 100 ("100 speed film"), the aperture is set to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [2] seconds (on some cameras 1 / 125 second is the closest available setting to 1 / 100 second). On a sunny day at ISO 200 and aperture at f /16, set shutter speed to 1 / ...
Originally, ASA values were frequently referred to as American standard speed numbers or ASA exposure-index numbers. (See also: Exposure Index (EI).) The ASA scale is a linear scale, that is, a film denoted as having a film speed of 200 ASA is twice as fast as a film with 100 ASA.
A scene will be properly illuminated for every combination of f‑stop and distance shown on this flash device's exposure calculation dial, each of which equals the same guide number. The guide number here (full power setting, ISO 100, and normal-angle coverage) is 37 for calculations made in meters (yellow arrow) and 120 for feet
Scientists have documented the widespread exposure of more than 600 animal species to toxic “forever chemicals,” in a new interactive map released on Tuesday. As contaminated wildlife crop up ...
An appropriate exposure for a photograph is determined by the sensitivity of the medium used. For photographic film, sensitivity is referred to as film speed and is measured on a scale published by the International Organization for Standardization (ISO). Faster film, that is, film with a higher ISO rating, requires less exposure to make a ...
An example of the use of f-numbers in photography is the sunny 16 rule: an approximately correct exposure will be obtained on a sunny day by using an aperture of f /16 and the shutter speed closest to the reciprocal of the ISO speed of the film; for example, using ISO 200 film, an aperture of f /16 and a shutter speed of 1 ⁄ 200 second. The f ...
