HDRi (data format)

The proprietary HDRi data format is a 64bit (color) or 32bit (greyscale) data format for saving RAW data of HDR scans including infrared data in a TIFF container developed by LaserSoft Imaging.

Data format

Description

Some image scanners, especially film scanners provide an additional infrared channel. The data it collects during a scan can be used for image optimization, e.g. for scratch and dust removal. The infrared RAW data and the usual image RAW data get saved in the HDRi data format, where 16bit per color channel are used for every pixel and additional 16bit for the infrared channel. Thus, a HDRI color file devotes resources of 64bit per pixel and a HDRi greyscale file 32bit per pixel.

Application

The infrared RAW data is saved lossless with the image RAW data. Therefore, it isn't necessary to process them while scanning. This facilitates the digitalization of larger archives. Afterwards, the so filed originals can be post processed at any time with dust and scratch removal, possibly in batch mode.

Format (Common Lisp)

FORMAT is a function in Common Lisp that can produce formatted text using a format string similar to the printf format string. It provides more functionality than printf, allowing the user to output numbers in English, apply certain format specifiers only under certain conditions, iterate over data structures, and output in a tabular format. This functionally originates in MIT's Lisp Machine Lisp, where it was based on Multics ioa_.

Example

An example of a C printf call is the following:

Using Common Lisp, this is equivalent to:

Another example would be to print every element of list delimited with commas, which can be done using the ~{, ~^ and ~} directives:

Note that not only is the list of values iterated over directly by FORMAT, but the commas correctly are printed between items, not after them. A yet more complex example would be printing out a list using customary English phrasing:

Whilst FORMAT is somewhat infamous for its tendency to become opaque and hard to read, it provides a remarkably concise yet powerful syntax for a specialised and common need.

Format (album)

Format is a double-disc compilation album by English synthpop duo Pet Shop Boys. The album consists of B-sides from various singles released from 1996 to 2009 (Bilingual through Yes, or "Before" to "Did You See Me Coming?"). It is their second B-sides album after Alternative (1995), which collected B-sides from the time of their first version of "Opportunities (Let's Make Lots of Money)" (1985) through "Yesterday, When I Was Mad" (1994).

The album's release was initially announced in November 2011, then officially on 19 December 2011 through the Pet Shop Boys' official website, offering it for pre-order. The album was released on 6 February 2012 in the UK, but was released earlier in various territories worldwide, including Australia, where it was released on 3 February. The album debuted at number 26 on the UK Albums Chart, selling 5,909 copies in its first week.

High-dynamic-range imaging

High-dynamic-range imaging (HDRI or HDR) is a technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present the human eye with a similar range of luminance as that which, through the visual system, is familiar in everyday life. The human eye, through adaptation of the iris (and other methods) adjusts constantly to the broad dynamic changes ubiquitous in our environment. The brain continuously interprets this information so that most of us can see in a wide range of light conditions. Most cameras, on the other hand, cannot.

HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different narrower range exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, resulting in the loss of detail in highlights or shadows.

DATA (band)

DATA were an electronic music band created in the late 1970s by Georg Kajanus, creator of such bands as Eclection, Sailor and Noir (with Tim Dry of the robotic/music duo Tik and Tok). After the break-up of Sailor in the late 1970s, Kajanus decided to experiment with electronic music and formed DATA, together with vocalists Francesca ("Frankie") and Phillipa ("Phil") Boulter, daughters of British singer John Boulter.

The classically orientated title track of DATA’s first album, Opera Electronica, was used as the theme music to the short film, Towers of Babel (1981), which was directed by Jonathan Lewis and starred Anna Quayle and Ken Campbell. Towers of Babel was nominated for a BAFTA award in 1982 and won the Silver Hugo Award for Best Short Film at the Chicago International Film Festival of the same year.

DATA released two more albums, the experimental 2-Time (1983) and the Country & Western-inspired electronica album Elegant Machinery (1985). The title of the last album was the inspiration for the name of Swedish pop synth group, elegant MACHINERY, formerly known as Pole Position.
