Chinese New Year 2005

On Sunday 13th 2005, 17 years ago, London was celebrating the Chinese New Year of the Rooster which started the previous Wednesday – it was 4072.

Chinese New Year in Soho is something I’ve avoided in more recent years – as I wrote in 2005: “I used to enjoy the rather anarchic celebrations in Chinatown, but it’s now more of an ordeal, with far too many people coming in to watch and too much organisation.”

Trying to photograph in such crowded situations was a problem, and one I confronted in two main ways in 2005, something reflected in the two pictures above. At the top is a picture taken standing back some distance with a telephoto lens, while the lower picture is taken with a fisheye lens, both on a Nikon D70 DX camera.

De-fished version

Usually now when I use the a fisheye lens like this, I would convert the perspective to give straight verticals – as in the above image. But back in 2005 I didn’t have a good plug-in to do this conversion, and although it was possible with various programmes I was using for making panoramas it was a rather time-consuming process.

For this particular event I rather liked the fisheye effect, at least in some pictures. Although it does clearly misrepresent those faces close to the edges of the picture, for me it pulls the eye towards the centre of the picture and perhaps gives a greater impression of the crowding I was working in.

A small problem is that the image you see in the viewfinder is the fisheye one, and not that in the ‘de-fished’ version. But as you can see, the fisheye image which you see has the same horizontal limits at the centre of both the horizontal and vertical sides, with just a little of the image towards the four corners being lost. It’s still possible to frame accurately when working.

It’s not I think correct to call the effect of the fisheye lens ‘distortion’. It is simply a different way of recording the subject on a flat rectangle. Most fisheyes I’ve used (and I own four different examples, for DX and full-frame Nikon, for Fuji and for micro 4/3) seem actually to have rather less actual distortion than my ultra-wide rectilinear (i.e. ‘normal’) lenses.

In the de-fished image you can see that as well as the verticals of the building being straight, people at the edges of the picture are also shown naturally, unlike in the fisheye version. I was also taking some pictures with an ultra-wide 12-24mm lens (equivalent to 18-36mm full-frame) and with that at its widest faces at the edge would have been rendered a little stretched out horizontally.


I’m not sure what some major agencies would make of conversions using software like this, whether they would regard it as an unacceptable alteration of the image. For me its just one of many acceptable corrections of the image, but clearly it does alter the image as recorded by the camera. It would be possible to design a specialised wide-angle camera which carried out the correction in firmware but the market for this would probably be small. Rather it could be provided into normal digital cameras as an option – far more useful than all those special effects which clutter the menus on many cameras now.
