Infrared: The Campsie Hills from Bishopbriggs

wow.. you're quick.. just uploaded it. It was taken with a sony cybershot dsc-v3 which I'm abusing a little in order to photograph in infra red. There's lots of hacks on the net about removing the ir filters from your digi cam and replacing them with chips of exposed developed film which cuts out all light except infrared..

I'm not ready to pull this camera apart but fortunately it has a night shooting mode which removes the IR filter. Unfortunately when the mode is activated it severely hobbles the cameras aperture and shutter controls. I'm experimenting with overcoming these problems without doing anything drastic to my cam - I'm forced to shoot at 1/30th of a second @ f2.8 this causes over exposure and camera shake.

So it's a case of use a tripod and cut the light going into the lens. At the moment I've got 2 layers of exposed film over the lens. Even then it tends to over expose a bit so I'm going to try adding an ir filter next.

I'm going to start a thread in the forum about IR to discuss this further.

1: yes. some cameras have a night vision mode. Think of the infamous Paris Hilton video. These modes are sensitive to IR light. You can also hack a digi cam to make it more sensitive to IR light.

2: not quite. The DSCv3 night vision mode forces the camera to take a long exposure. It would be better if it didn't but it thinks you're shooting at night.

3: I need a tripod because of 2.

4: pieces of negative films, yes. A processed exposed bit of negitive film. I suppose a processed unexposed bit of slide film would work too. The point is this will block all the visible light but let the infrared light through.

the conversion is in your camera. you can't see IR but a ccd imaging chip sure can. Quick experiment to prove it. Take your digi cam and go find your IR TV remote. You can't see the infrared LED flashing when you press the buttons on the remote (unless it also has a colored led) but look again through the preview screen of a digicam (not the viewfinder).. You CAN see the ir - or rather your camera can and it converts it to visible light.

I've created a thread on the message board for IR discussion so if you've got any more questions put 'em there and we may get input from a few other people too.

I love the ethereal, ghostly effect of this shot. I have just bought a B+W 093 filter for my Nikon Coolpix 950. I am waiting for a bright sunny day so I can have a go at infrared photography.
