What is a fast lens in photography? A fast lens refers to a lens with a wide maximumaperture. The larger the maximum aperture, the faster the lens. Note: A lens’saperturerefers to a hole in the lens, which opens and closes depending on your camera settings. A wide aperture has certai...
Photography has a lot of confusing terminology, and often there are several ways to describe the same idea. One of the more annoying ones is when lenses are called “fast”. How can a lens have a speed? If you drop two lenses, they’ll both hit the ground (and break) at the same ...

If you're looking for really big amicable pairs, say bigger than 2^64, then on a small number of machines you can't do it by factorising every single number no matter how fast your factorisation is. The short-cuts which you're using to find candidates might help you factor them. Share...
what is a camera? a camera is a device that captures light and processes it into an image. it does this through a lens, which focuses the light onto a light-sensitive surface where a picture is formed. this could be film in traditional cameras or an electronic sensor in digital cameras....
Aperture is the adjustable lens opening that controls the amount of light allowed into the camera. It functions much like the pupil in a human eye, which dilates to let in light and narrows in bright settings. Your aperture setting is measured in what’s known as an f number, also called...
It is a 1/2.6″ (Diagonal 6.8 mm) optical format CMOS sensor with a 3.0 μm x 3.0 μm pixel size. It is a global shutter sensor that is used for accurate and fast capture of moving scenes at 120 frames per second at full resolution.See3CAM24_CUG fr...
The kind of lens you should use depends on the kind of photography you do. If you need a fast, low-light lens for astrophotography, then an aperture of f/2.8 or wider is the way to go. But if you’re a landscape photographer in broad daylight, a low f-stop might not be as impor...
