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]
Tri-X 400 is the more common of the two, available in 24- and 36-exposure rolls of 35 mm and rolls of 120 as well as 50 and 100 ft bulk rolls of 35 mm. Tri-X 320 is available in 4×5", 5×7", and 8×10" sheets. Tri-X 400 is usually rated at ISO 400 when processed in standard developers and remains among the fastest black and white films today.
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 ...

A takeoff/go-around switch (TO/GA; / ˈ t oʊ ɡ ə /) is a switch on the autothrottle of modern large aircraft, with two modes: takeoff (TO) and go-around (GA). The mode is dependent on the phase of flight; usually, on approach to land, the autopilot will be set to approach mode, therefore if the TO/GA switch is pressed it will activate the go-around mode of the autothrottle (about 90–92% ...
When a lens is immersed in a refractive medium, its optical power and focal length change. For two or more thin lenses close together, the optical power of the combined lenses is approximately equal to the sum of the optical powers of each lens: P = P 1 + P 2. Similarly, the optical power of a single lens is roughly equal to the sum of the ...
Then, at a speed of 13 400 000 m/s (30 million mph, 0.0447 c) contracted length is 99.9% of the length at rest; at a speed of 42 300 000 m/s (95 million mph, 0.141 c), the length is still 99%. As the magnitude of the velocity approaches the speed of light, the effect becomes prominent.
