A photography exhibition paying tribute to Kodachrome film, axed because of falling sales, has proved so popular that it has been extended.

The Association of Photographers (AoP) in London has bowed to photographers? calls by extending ?A Celebration of Kodachrome? until 25 February.

An AoP spokesman explained that the two-week extension was due to ?popular demand?.

The gallery launched the show in response to news that Kodak had stopped production of the iconic emulsion after 74 years.

These days Kodachrome slide film can no longer be processed, after the only lab accepting the film processed its last roll at the end of 2010.

Kodachrome was the world’s first commercially successful colour film and was respected by amateurs and professionals alike.

It found favour with many high-profile photographers including, Steve McCurry who used the film for his famous 1984 photo Afghan Girl. The image was used on the cover of National Geographic Magazine the following year.

Kodak discontinued Kodachrome production in 2009, saying that it only made up 1% of Kodak’s total film sales.
