IR Experiment

This is a Lime. A deep green lime to be precise.

It's white (relatively speaking) because I improvised an IR (infrared) filter over the lens when I shot it.

It's noisy because it's shot at iso1600.

It's blurry because I had to hold the "filter" over the lens by hand and thus introduce camera shake.

And finally, it's not full IR because there was some minor light leaks from the filter and because I didn't have exactly the right material.

So what did I use ? Well ideally you'd use two sheets of unexposed developed slide film. However I only had exposed slide film, so I used two very underexposed slides taped together and then held that over the lens.

Not particularly useful, but an interesting effect none the same.

    That's pretty awesome Greg. I might need to rig a proper filter arrangement and try this out some more.
