How is all this possible?

Firstly, by the the skill, persistence, and generosity of the Developers, and other contributors to the CHDK project.

Secondly, in the same way that your computer hardware runs an operating system, such as Windows, Mac OS, or Linux, your Canon camera also has an operating system in it. And in the same way that your OS runs Photoshop or Zoombrowser on your computer, the OS in your camera is also able to run programs such as CHDK.

Does CHDK permanently alter the camera?

No. CHDK is simply software. Just like your computer, when the camera is turned off all the software disappears from memory until it is turned on again and CHDK is loaded again. Also like some software, there is an option to automatically start CHDK when the camera starts.

How does CHDK get on the camera?

In the same way that you install Photoshop or Zoombrowser onto your computer (by copying the software onto your hard drive,) CHDK is installed by copying the CHDK software onto the camera’s 'hard drive'...the SD flash memory card.

How does CHDK software get copied to the flash card?

You can copy software to your SD flash card using a file manager such as Windows Explorer. A card reader must be used to connect the SD flash card to your computer. Once connected, the SD flash card appears like any other hard drive on the computer. Your printer may contain a usable card reader. Card readers are fairly inexpensive, and can simplify transferring of files, although given the right file naming, files can be transferred via USB. See:- Raw Parameters, and DNG visible via USB.

Atkinsons Carillon Tower in London

Atkinsons Carillon is the only carillon tower in London.

See the detailed information found at:

British Carillon Society

London Remembers

The Plaque

Atkinsons Carillon is located atop Atkinson's Building at 24 Old Bond Street. It has 23 bells which are described in detail at the Westminster Love's guide.








Some of the links on this posting take you to websites which have better photos of Atkinsons Carillon than we show you here, but for our photos here we had to take the weather, the hour - and camera - as they were. There are only a limited number of carillons in the world, and there is an incomplete list in the Wikipedia at List of carillons. Our own domicile, Traben-Trarbach, in Germany has an Old City Tower with a carillon, restored in the year 2004.

Handbags to high heels at Selfridges : The Man Who Made Shopping Fun : How Many Shopping Days are Left Until Christmas?

The founder of Selfridges was the first entrepreneur to promote retail Christmas sales using the phrase "Only (so many) Shopping Days Until Christmas".



Christmas 2008. "Handbags to high heels" at Selfridges.

As written at the Wikipedia, Selfridges is the 2nd largest department store in the UK after Harrods, and, amazingly enough, it was founded by an American:


"Selfridges is a chain of department stores in the United Kingdom ... founded by American entrepreneur Harry Gordon Selfridge. The flagship store in London's Oxford Street is the second largest [department store] in the UK (after Harrods) and was opened on 15 March 1909....

... Selfridge was born in 1858 in Ripon, Wisconsin, and in 1879 joined Field, Leiter and Company (later to become Marshall Field & Company), where he worked under the Chicago retailer of the same name. He worked his way up through the firm, married into the prominent Buckingham family, and amassed the fortune with which he built his new London store.

Selfridge's innovative marketing led to his success. He tried to make shopping a fun adventure instead of a chore. He put merchandise on display so customers could examine it, put the highly profitable perfume counter front-and-centre on the ground floor, and established policies that made it safe and easy for customers to shop — techniques that have been adopted by modern department stores the world over."

Piccadilly Circus, London, England, UK

Piccadilly Circus is London's comparable to New York's Times Square. These are the neon signs viz. LED screens on the northwest side of Piccadilly Circus. As written at the Wikipedia:

"Piccadilly Circus used to be surrounded by illuminated advertising hoardings on buildings, starting in the early 1900s, but only one building now carries them, namely the one in the north-western corner, between Shaftesbury Avenue and Glasshouse Street. The site is unnamed (usually referred to as Monico after the Café Monico which used to be on the site); its addresses are 44/48 Regent Street, 1/6 Sherwood Street, 17/22 Denman Street and 1/17 Shaftesbury Avenue, and has been owned by property investor Land Securities Group since the 1970s.

The earliest signs used incandescent light bulbs, these were replaced with neon lamps, as well as moving signs (there was a large Guinness clock at one time). From December 1998 digital projectors were briefly used for the Coke sign, while the early 2000s have seen a gradual move to LED displays. The number of signs has reduced over the years as the rental costs have increased.

As of 2008, the site has six illuminated advertising screens above three large retail units, facing Piccadilly Circus on the north side, occupied by Boots, and GAP and a mix of smaller retail, restaurant and office premises fronting the other streets. A Burger King located under the Samsung advert which had been previously a Wimpy Bar until the late 1980s had closed in early 2008 and is presently being converted into a Barclays Bank.

Coca-Cola have had a sign at Piccadilly Circus since 1955. The current sign dates from September 2003, when the previous digital projector board and the site formerly occupied by Nescafé was replaced with a state-of-the-art LED video display that curves round with the building. On November 23, 2007 the very first film was broadcast through the board. Paul Atherton's film The Ballet of Change: Piccadilly Circus was allowed five minutes to show the first non-commercial film depicting the history of Piccadilly Circus and the lights.

The former Nescafé advert site had also been occupied by a neon advertisement for Fosters until about 1999 and for three months in 2002 between the display of the Nescafé advert and the enlarged Coca Cola advert this part of Piccadilly Circus had featured the quote "Imagine all the people living life in peace" by the late Beatle John Lennon. This was paid for by his wife Yoko Ono who spent an estimated £150,000 to display an advert at this location.

Sanyo's sign is the oldest out of the six, the current incarnation having been installed in the late 1980s and remaining unchanged ever since. However, earlier Sanyo signs with older logos have occupied that position since at least 1980.

TDK replaced the space formerly occupied by Kodak in 1990. Their sign has remained almost unchanged since, although in 2001 the colour of the background lamps were changed from green to blue, and the words 'Audio & Video Tape' and 'Floppy Disks' under the logo was removed.

McDonald's added a sign in the mid-1980s, replacing one for BASF. In 2001 the sign was changed from neon to an animated LED screen, which was further changed to a bigger, brighter LED screen in 2008.

Samsung replaced a sign for Panasonic in November 1994, and the sign was upgraded from neon to LED in 2005.

Piccadilly Lite was added on 3 December 2007, placed under the Samsung and McDonald's signs. This is an LED screen that allows other companies to advertise for both short and long term leases, increasing the amount of advertising space but using the same screen for multiple brands."
