(Redirected from 4:3)
Full screen or fullscreen refers to the 4:3 (1.33:1) aspect ratio of early standard television screens and computer monitors.[1] The 4:3 aspect ratio became the standard in film because it mirrored film stock and was the easiest to use.[2]Widescreen ratios started to become more popular in the 1990s and 2000s.
Film originally created in the 4:3 aspect ratio does not need to be altered for full screen release, while other aspect ratios can be converted to full screen using techniques such as pan and scan, open matte or reframing. In pan and scan, the 4:3 image is extracted from within the original frame by cropping the sides of the film. In open matte, the 4:3 image is extracted from parts of the original negative which were shot but not intended to be used for the theatrical release. In reframing, elements within the image are repositioned. Reframing is almost exclusively a method used for entirely CG movies, where the elements can be easily moved.[3][4]
History[edit]
Full screen aspect ratios in standard television have been in use since the invention of moving picture cameras. Early computer monitors employed the same aspect ratio. The aspect ratio 4:3 was used for 35 mm films in the silent era. It is also very close to the 1.375:1 Academy ratio, defined by the Academy of Motion Picture Arts and Sciences as a standard after the advent of optical sound-on-film. By having TV match this aspect ratio, movies originally photographed on 35 mm film could be satisfactorily viewed on TV in the early days of television (i.e. the 1940s and '50s). When cinema attendance dropped, Hollywood created widescreen aspect ratios (such as the 1.85:1 ratio mentioned earlier) in order to differentiate the film industry from TV.[5] However, since the start of the 21st century, broadcasters worldwide began phasing out the 4:3 standard entirely as manufacturers started to favor the 16:9/16:10 aspect ratio of all modern high-definition television sets, broadcast cameras and computer monitors.

What is screen gain?
Every screen product on the market has a 'gain' factor. Some screens are 'low gain' and some are 'high gain.' Most white home theater screens are low gain, and carry ratings in the range of 1.0 to 1.3 gain. Some of today's gray screens are rated as low as 0.8 gain. On the other hand, one vendor is marketing screens with gain ratings that they claim are as high as 6.0. However, unless you have gone shopping for a screen before you are not likely to know what any of these numbers mean.
Gain is a measurement of the reflectivity of any screen or projection surface. The gain number represents a ratio of the light that is reflected from the screen as compared to the light reflected from a standard white (magnesium oxide) board. Copy pasta 1 0 2 download free. Therefore, a screen with a gain of 1.0 will reflect the same amount of light as that from a white board. A screen rated at 1.5 gain will reflect 50% more light as that from a white board, whereas a gray screen with an 0.8 rating will reflect 80% of the light from a white board.
Gain is measured from the vantage point where the screen is at its brightest, which is directly in front and perpendicular to the screen. Technically the measurement of gain at this point is known as Peak Gain at Zero Degrees Viewing Axis. Alfred 4 powerpack v4 0 7 (1130). If you move to the side and view the screen at an angle the brightness of the projected image drops. The angle at which the gain reading drops to 50% of the peak value is known as the Half Gain Viewing Angle. A person viewing the screen from this angle will see an image half as bright as the person seated at the center position.
Low gain screens have wider Half Gain Viewing Angles than do high gain screens. That is because the low gain screen diffuses light more evenly over a wider angle of view. A high gain screen is constructed to reflect more of the projector's light energy back toward the centerline of the projection path, and less light energy to the oblique angles of view. Thus brightness falls off more rapidly as you move away from the zero degree viewing axis, and the Half Gain Viewing Angle is relatively narrow.

Is high screen gain good?
It is easy, and wrong, to jump to the conclusion that a high gain screen must be preferable to a low gain screen. After all, higher reflectivity means a brighter image and a brighter image seems like a good thing, right? The problem is that there are some downsides to higher gain in a home theater environment.
First, as just noted there is a trade-off between gain and viewing angle. A 1.0 gain screen diffuses light evenly in all directions. Thus seating can be placed in a wide viewing angle relative to the screen and all seats will afford a similar viewing experience regardless of the angle of view. With a high gain screen the brightness of the image increases to those seated in the center, and diminishes for those seated at the outside. Furthermore once you move off center axis the relative brightness of various portions of the image can shift quite dramatically. Thus a high gain screen can put limitations on the number of optimum viewing seats you can have in your theater.
Second, a high gain screen does not typically reflect red, green, and blue equally. So it can generate color shifts in the image that are noticeable as you move around the screen viewing it from different angles. Once again, the image looks different to each viewer depending on where they are seated.
Third, any screen with a gain higher than 1.0 has some degree of hotspotting. That is, when viewing the screen from a center position, the middle portion of the image will appear brighter than the edges. On screens under 1.3 gain or so this is not very noticeable, but as gain increases beyond 1.3 it can become a real distraction.
High gain screens have a definite place in the world. In conference rooms and classrooms where you want some lights on and most of the seats can be positioned within the screen's narrow cone of reflectance, high gain screens can be quite effective in boosting image brightness.
