Cutaway drawing of an early photographic lens design, the Petzval Portrait The invention of the camera in the early 19th century has led to a large array of lens designs intended for photography.
Monitor/EVF Holder. Untitled. History of photographic lens design. Spherical aberration. Not to be confused with barrel distortion, in which the image appears to be warped onto a sphere.
The bottom example depicts a real lens with spherical surfaces, which produces spherical aberration: The different rays do not meet after the lens in one focal point. The further the rays are from the optical axis, the closer to the lens they intersect the optical axis (positive spherical aberration). (Drawing is exaggerated.) What is the Aspect Ratio? (4:3, 16:9, 21:9) A TV's (and every other image's) aspect ratio is the proportion between the width and the height of a picture.
It is often expressed in the W:H format, where W is the width and H the height. For example, a 16:9 aspect ratio means that for a width of 16 units, the height must be 9 units. The most common aspect ratios in the video industry. Most televisions and computer monitors currently available have an aspect ratio of 16:9, which offers a perfect fit for high definition television shows. However, movies are usually filmed with a ratio of 21:9, which will result in black bars at the top and bottom of the picture when it is displayed on the average TV.
In theaters, this is why the screen widens at the beginning of a movie. Everything You Wanted To Know About Rolling Shutter. Rolling Shutter is the way that most DSLR are shooting video.

La temperatura de color: cómo conseguir el ambiente ideal con lámparas LED.
Temperatura de color. A Tedious Explanation of the f/stop. By Matthew Cole Photographers set their exposure using a combination of shutter speeds and f/stops to get the correct amount of light on the sensor (or film).
The shutter speed regulates how long the sensor is exposed to light coming through the lens. The f/stop regulates how much light is allowed through the lens by varying the size of the hole the light comes through. For any given film speed (ISO) and lighting combination there is one correct amount of light to properly expose the image. Photography and Math. Photography and Math Copyright 2004, 2010, Mark D.
