Infrared filters

Has anyone tried to film with an infrared filter in front of the lens?

I know you won't be able to see anything through the viewfinder, but will the chip in the camera be able to "see" through it, and get something useful?

Maybe I misunderstand the question...

Most camcorders have an infrared filter in them (to remove infrared from incoming spectrum).

The "far red" filters that have been a topic of conversation for the original EX1, EX3, and RED cameras actually filter red in the visible spectrum...not really infrared. These cameras will typically demonstrate a subtle to obvious red sensitivity when looking at a black surface (cloth is usually the worst), and filters like the Tiffen T1 that I use (as well as several other products that are available) reduce that red tint in those dark surfaces.

I know of no filter you could put in front of a lens and "see" infrared through the camera's internal filter, but I have seen a scenario where someone took a consumer camcorder apart and removed the internal filtering system...

Many of the consummer cameras have a "nightshoot" mode that actually moves the IR cut filter from the optical path. Probably one of those cameras in conjunction with an IR pass filter would do the trick.

Alrighty then,

I read someof the past posts, and decided to try it out.

I put my filter on my Optura, and was amazed at how well it worked and the great results.
The colour was not what I expected, a bonus, as I was expecting a reddish magenta colour.
I got a sepia colour tone,which would look interesting, for a period kind of look.

I play some more for the weird look and then mess with it in post, to see what I can come up with.

???????

I have no idea how you read what I wrote and expected a reddish tint... As I said, it -filters- red.

The Tiffen T1 I mentioned takes out the red tint in the blacks that certain cameras have...the opposite of a red tint.
