American Family Radio

American Family Radio (AFR) is a network of more than 160 radio stations broadcasting Christian-oriented programming to over 40 states. AFR is also available to both watch and listen worldwide on their website.

Overview

AFR was launched by Rev. Donald Wildmon in 1991 as a ministry of the American Family Association, with the flagship station being WAFR in Tupelo, Mississippi.

AFR airs original programs such as Today's Issues, hosted by AFA president Tim Wildmon, AFA Report, "a daily panel discussion with members of the AFA staff regarding hot-button issues of the day", formerly hosted by AFA founder Don Wildmon and Focal Point, hosted by Bryan Fischer. AFR also airs nationally syndicated programs such as Focus on the Family, as well as contemporary Christian music by various artists.

In 2009, AFR acquired the rights to its first politically oriented talk show when it picked up Michael Reagan's syndicated program (this show is no longer available on AFR as of Spring 2010).

Film speed

Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to measure the sensitivity of digital imaging systems.

Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.

Historical systems

Warnerke

The first known practical sensitometer, which allowed measurements of the speed of photographic materials, was invented by the Polish engineer Leon Warnerke – pseudonym of Władysław Małachowski (1837–1900) – in 1880, among the achievements for which he was awarded the Progress Medal of the Photographic Society of Great Britain in 1882. It was commercialized since 1881.
