Do you need to load the right kind of film, check the F-stop
, or even focus the thing?
Each change in f-stop
corresponds to a doubling or halving in aperture size.
"Our new HDR camera technology and software enables us to capture and display dynamic HDR images, covering at least 20 f-stops
, at full high-definition resolution, and at 30 frames-per-second.
The N86 is Nokia's new 8 megapixel camera phone and it will sport a wide-angle Carl Zeiss Tessar optics lens with a mechanical shutter up to 1/1000 and a f-stop
range of 2.4-4.8 to suit low light conditions.
The lens is infrared (IR)corrected to keep FlexiDome day/night cameras in focus at all times, and has an f-stop
of f/1.4 to allow a greater amount of light to pass through the lens to the image sensor--resulting in enhanced sensitivity and fast reaction to light-level changes.
They had already practiced the technique of reciprocity: making shutter speed, f-stop
, light and film speed agree.
Your shutter speed stinks, F-stop
is funky and your lens cap is on.
(1) For instance, while taking a picture, a person can use a narrow f-stop
and a fast shutter speed to make a photograph taken during the day appear as if someone took it at night.
The HDRC camera does not require an F-stop
, shutter control, or an additional light source.
It delivers unprecedented image quality, 10 f-stop
dynamic range, a 7-inch LCD touchscreen interface, gigabit connectivity, battery-powered operation, and up to 4 hours of continuous shooting on its USB2.0 hot-swap 160GB notebook hard drive.
They provide a high-resolution image and fast F-stop
with infrared corrective feature for removing the focus shift between day and night modes.
The electronic lens control allows speeds to 1/500 second an 1/10 f-stop
intervals, producing accurate and consistent shutter performance.
