Really big IR filter!

I saw something last week about a 6" IR filter on eBay.

It was 7 bucks so I went for it.

It came and sure enough it was a 6"dia. opaque filter so I immediately went out and shot through it to see what was up. It indeed is a deep IR filter, I would guess 900-1000nm judging from the other filters that I have . . .but . . the image was waaaay fuzzy.

Then I realized what it is, . . a light source filter (woo hoo) to project IR.

Well today I saw that the seller was selling 3 more so I snapped them up. This is going to be fun. ;D

Cheers

Hey Jules, so what have you got planned for these filters?

Well you can try rigging up a spotlight and using a B&W IR sensitive film. If you can entice wildlife within range of the IR, they will totally ignore it. You'll need IR sensitive glasses though...

You can use colour IR film and de-saturate it (everything will come out as red instead of whites and greys).

Not speaking from experience of IR film here - did some work with IR illumination for CCTV. Worked fine with low light level B&W cameras, but as soon as we got ambitious and tried using a Camcorder, everything turned red!

Hi Heath,

Basically, studio IR shooting. I shoot sometimes with a Sunpak 622 that has an IR flash head (multiple interchangeable heads on the unit) but would like to have a steady source.

BTW I bought 3 more so I can flood an area.
