Converting a Webcam to Infrared
Inspired by this post, I decided to have a bash at converting an old webcam to infrared.
The camera was a cheapy Phillips (one with a lens that completely unscrews exposing the ccd). Don’t use a camera that you care about. This process may knacker it!
First the infrared filter needs to come out - In this case I had to use a knife to prize the end away from the lens housing. There’s a groove around the top which gives way allowing you to pull the filter (a tiny square piece of glass) out.
Next, you need to filter out the visible spectrum. I used the really dark bit that you get at the beginning of a strip of negatives (the blacky/blank bit that comes before the pictures). Cutting out a small square of that, I popped it back into the lens housing (in place of the infrared filter I’d removed) and forced the end bit back on trapping it in place.
That’s about it. It seems to work reasonably well, although of course you loose quite a bit of quality. I’ll add any photos I take to my infrared experiment gallery here. I’ve attached a couple here too.
Check out the coke - It’s transparent when viewed in infrared!
Not a very good shot, but the grass looks pretty wierd.
