In cameras that save in a lossless format, resizing in post-production yields results equal or superior to digital zoom. [citation needed] Lower-end camera phones use only digital zoom and do not have optical zoom, while many higher-end phones have additional rear cameras, including fixed telephoto lenses that allow for the simulation of ...
Videos usually feature animals getting into humorous circumstances caught on camera; while others include animals displaying interesting capabilities or behaviors. The show also features interspersed animal facts, which often introduce connected videos, or are formed as trivia questions to the audience to bookend commercial breaks.
Video magnifiers are electronic devices that use a camera and a display screen to perform digital magnification of printed materials. The display screen is usually LCD or a similar flat-screen technology (although older video magnifiers have used CRT displays), and the device usually includes a lamp to illuminate the source material.
Live preview on LCD. The concept for cameras with live preview largely derives from electronic TV cameras.Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism.

But unlike changes in camera position, zooming does not change the perspective (the relative sizes of near and far objects); it only magnifies or reduces the size of the entire image as a whole. Zooming can either be performed towards longer focal lengths, giving a "zoom in" effect: The filmed object will then increase in apparent size, and ...
From mountain lions to a pizza delivery guy foiling a robbery attempt, cameras meant to protect post-pandemic purchases provided endless entertainment this year. Here are some of the wildest ...
Digital photography can also accommodate algorithms that compensate for optical flaws, both within in-camera processors and post-production software. Some photographic zoom lenses are long-focus lenses , with focal lengths longer than a normal lens , some are wide-angle lenses (wider than normal ), and others cover a range from wide-angle to ...
