* When photographing from behind tinted glass, they should remember that they will lose at least one f-stop
(i.e., the function that regulates the amount of light coming through a camera lens).
Kodak Professional's proprietary Extended Range Imaging Technology provides two f-stop
exposure latitude in JPEG workflow.
The Vari-Focal TV5513 for 1/3" cameras features an f-stop
of f-1.3 for low light conditions.
The camera features manual focus and shutter controls, six shooting modes and 13 f-stop
aperture control settings, as well as a multiple exposure mode and histogram display like the ones found on Fujifilm's advanced digital SLR camera, the FinePix S1 Pro.
The focus range is 36 inches to infinity, the f-stop
is 2.0, and it has shutter speeds from 1/15 to 1/500 second, There is a 2X zoom in the higher resolution mode.
Start by making the exposure indicated by the camera's light meter, then make another exposure a half f-stop
over the indicated exposure and another one a half f-stop
Sometimes there is as much as a two f-stop
difference because the filter blocks out some light.
Famous landmarks snapped by Steve Mayes, including the Angel of the North, Druridge Bay in Northumberland, Bamburgh Castle, Holy Island and the Baltic are on sale at the F-Stop
Gallery, on Stepney Bank, Newcastle.
The latitude in digital exposure is much narrower and color sensitive than the 'three f-stops
under' latitude of color negative emulsions.
Iris and f-stop
. The iris of the lens is referred to as the center focal point of the lens and is mounted at the aperture of the lens.
If a mirror is not available and the puddle is in shadow but the people or objects are in sunlight, there will be a two f-stop
exposure difference between what is darkest and what is lightest.
As a general rule of thumb, the lower the f-stop
, the blurrier the background, and the effect is accentuated by getting closer to your subject.
