There are two primary types of photographic film: Print film, when developed, turns into a negative with the colors (or black and white values, in black and white film) inverted. This type of film must be "printed" — either projected through a lens or placed in contact — to photographic paper in order to be viewed as intended. Print films are available in both black & white and color. Color reversal film after development is called a transparency and can be viewed directly ...

Large format SLR cameras were first built in the early years of the 20th century but were not very popular. Although the Soviet GOMZ sport (1935) was the first 35 mm SLR, it was the Ihagee Kine-Exakta (1936) that was truly influential. Further Exakta models, all with waist-level finders, were produced up to and during World War II. Meanwhile, Zeiss developed the eye-level viewfinder and pentaprism in prototype form, but the war i ...

The first motive power set on Super Chief-1 consisted of a pair of blunt-nosed, diesel-electric units (EMD 1800 hp B-B) designated as Nos. 1 and 1A. Santa Fe employees quickly hung the nicknames "One-Spot Twins" and "Amos & Andy" (from the popular radio show of the day) on the units, which were always paired and ran back-to-back. In a little over a year the EMD E1, a new and improved 3,600 hp (2.7 MW) streamlined diesel-electric locomotive set (one hood unit and the other a cabless booster unit) ...

The lowest end point and shoots are similar to disposable cameras, but can be reloaded. These cameras have focus free lenses, with fixed apertures. They may have a light meter. Most have a wheel or lever for advancing the film and cocking the shutter, and a crank for returning the film to the canister for unloading. Because of the fixed apertures, models with flash have no way of controlling the exposure from the flash. Therefore flash pictures have to be taken with the sub ...

The Parthians were members of the Parni tribe, a nomadic people of Iranian origin, who spoke an Iranian language and entered the Iranian plateau from Central Asia. They were consummate horsemen, known for the 'Parthian shot': turning backwards at full gallop to loose an arrow directly to the rear. Later, at the height of their power, Parthian influence reached as far as Ubar in Arabia, the nexus of the frankincense trade route, where Parthian-inspired ceramics have been found. The power of the early Parthian empire seems to have been overestimated by some ancient historians, w ...

In one of the first chapters of the Agricola Tacitus said that he wished to speak about the years of Domitian, of Nerva, and of Trajan. In the Historiae the project has been modified: in the introduction, Tacitus says that he will deal with the age of Nerva and Trajan at a later time. Instead, he will cover the period that started with the civil wars of the Year of Four Emperors and ended with the despotism of the Flavians. Only the first four books and 26 chapters of the fifth book have survived, covering the year 69 and the f ...

132 is a Catalan number, a Harshad number, a pronic number. If you take the sum of all 2-digit numbers you can make from 132, you get 132: 12 + 13 + 21 + 23 + 31 + 32 = 132. 132 is the smallest number with this property. But there is no number that, when added up to its own digits, adds up to 132, making it a self number. ...

While other Christian denominations also lay claim to the description "catholic", including the Eastern Orthodox Church and those Protestant Churches possessing an episcopate (bishops), the term "Catholic Church" is usually associated with the Church that is also called the Roman Catholic Church, whose over one billion adherents are about half of the estimated 2.1 billion Christians. At the First Vatican Council of 1870, it referred to itself as the "Holy, Catholic, Apostolic and Roman Church",[1] but normally, both before and afterwards, it ...
