The 'Delta 3200' product is not actually rated at ISO 3200/36°. Its speed is only 1000/31° following the ISO methods, but it has a very wide exposure latitude. Thus it can be successfully push processed to EI 3200 or 6400, or even 12500. [1] Delta 3200 was introduced in 1998, 10 years after Kodak's similar T-MAX P3200. It replaced Ilford's ...
Kodak announced in February 2011 that Portra 160 was to be similarly replaced by a single version like the 400 and incorporate the same upgrades as the new 400 speed version. [10] This has been available since mid-2011 in 135, 120, 220 and sheet format. The new film is easy to scan, according to reviews. [11]

Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Polflucht (from German, flight from the poles) is a geophysical concept invoked in 1922 by Alfred Wegener to explain his ideas of continental drift.. The pole-flight force is that component of the centrifugal force during the rotation of the Earth that acts tangentially to the Earth's surface.
The 8th parallel north is a circle of latitude that is 8 degrees north of the Earth's equatorial plane. It crosses Africa, the Indian Ocean, South Asia, Southeast Asia, the Pacific Ocean, Central America, South America, and the Atlantic Ocean. The parallel defines part of the border between Somalia and Ethiopia.
The 85th parallel north is a circle of latitude that is 85 degrees north of the Earth's equatorial plane, in the Arctic.This parallel lies entirely within the Arctic Ocean.. At this latitude the entire sun is visible for 24 hours, 0 minutes during the summer solstice and during the winter solstice, the latitude is under total nighttime during the entire day.
The 44th parallel north is a circle of latitude that is 44 degrees north of the Earth's equatorial plane.It crosses Europe, the Mediterranean Sea, Asia, the Pacific Ocean, North America, and the Atlantic Ocean.
