Prince Regent Royal Pavilion

nobody@flickr.com (Dominic's pics) — Mon, 02 Mar 2009 13:54:26 -0800

Part of a set photographs of the Prince Regent's Royal Pavilion (also known as Brighton Pavilion).

Built in the Indo-Saracenic style, borrowing ideas from Indian architecture in the days when that region was still part of the British Empire.

Unlike the originals, the building's frame is Cast Iron - cutting edge technology at the time when the building was redeveloped by the architect en.wikipedia.org/wiki/John_Nash_(architect) are actually very small scale - much too small for an adult to fit inside. Like the shrunken higher up windows and tapering outline of the Senate House of London University, the reduction in size of the minarets adds to the illusion of scale.

There is an official Royal Pavilion website.

During Work War II, Adolf Hitler is famously claimed to have spared the Pavilion from bombing because he wanted to use it has his English headquarters. This is reputed to be based on statements by William Joyce, an American born German radio propaganda broadcaster (named Lord Haw-Haw by British listeners), statements presumably made to demoralise listeners into the belief that this outcome was inevitable. Brighton was bombed, however, so maybe the Luftwaffe just missed.

The image is made up from High Dynamic Range (HDR) files. A large number of (identically framed) bracketed exposures were merged into a single HDR file. This 32 bits per channel file (over 4 billion shades of red, green or blue) was converted to a more mundane 8 bits per channel jpeg file. (It is not currently technically feasible to fully display 4 billlion shades per colour on a computer monitor, or on a print.) In the conversion process Local Adaptation was used, a trick that enables the detail in both very bright (floodlit) areas and very dark (moonlit) areas to be viewed in the same image. The human visual system is particularly sensitive to detecting edges, and "overlooks" intervening smooth gradients. This makes Local Adaptation a viable technique / optical illusion.

The image has also been modified using transformations to remove any barrel distortion, and also adapted to ensure a classical perspective with parallel verticals.

Moon and Venus

Photograph of the Moon and Venus in approximate alignment - taken about 5:48 p.m. (GMT) on Monday 1st December 2008 in Brighton, East Sussex, UK (50° 50' N 0° 09' W).

Jupiter also appeared nearby.

A 300mm lens was used on a Canon DSLR body.

Moon, Venus and Jupiter with Earthlight

Jupiter is in the top right hand corner.

This is a composite image, a combination of two exposures. The more sensitive exposure (with a very high, noisy, ISO setting) revealed two stars near the moon, and two more near Jupiter. The illumination of the dark side of the moon (by light reflected from the earth) is also apparent. The dark band on the moon is an artifice - the more sensitive exposure was swamped by glare spilling out of the brighter crescent, which was "Photoshoped" out for cosmetic reasons. Most of the very noisy brighter exposure was removed from the image, except for the earthlight and the areas in the immediate vicinity of the four new stars that were revealed.

The viewpoint (often used in picture postcards) is also deceptive. By perching the camera on the edge of a small (four paces by ten paces) ornamental pond, the false impression is created that the pavilion is adjacent to a huge lake.

A Canon 300D DSLR was used. The number of exposures ranged from 1/250 sec. to 30 secs. in 2 EV/stop increments. Two large, nervous, ornamental carp live in the pool. I think that they moved about between exposures, causing the feint, strange, multiple streaks in the surface of the pond.

The image has also been overlaid with a simulation generated by the NASA JPL (Jet Propulsion Laboratory) Solar System Simulator at: space.jpl.nasa.gov/ The simulator generates "point to point" views between solar system objects. The (grey) computer generated moon appears displaced from the position of the real moon because the JPL viewpoint is from the centre of the earth (and not Brighton).

The JPL overlay confirms the feint blobs as stars, and indicates a few more. And also adds labels to Venus and Jupiter!
