This is more or less the raw image - all I've done to it is stretch the contrast, since it was originally squashed up at one end of the spectrum:

This is the same image with the sky left coloured (more or less) and the rest colourised back to grey-ish. This isn't a particularly neat job, it's more a test of the method than anything else.

A couple of shots I took with the aperture wide open - not surprisingly they're out of focus, but converted to grey scale they look quite interesting.


Afterwards I walked on through the park and saw a couple of parakeets flying around - they seem to be established fairly well in Hyde Park. I was changing to a telephoto lens when one flew within three or four feet of me - REALLY annoying - then they both retreated to the tree-tops and I couldn't get a decent shot. So have a squirrel instead...

I've picked up a cheap Sony Cybershot DSC-V1 that has a built-in infrared mode for night photography; unfortunately you need to use an IR filter and a neutral density filter to take infra-red in daylight, and a special holding tube since Sony didn't put a filter ring on the lens. I'm gradually sorting this out and hope to post some pictures soon.
