I hope this is the best place to post this (because its instructional) , if not I apologize in advance. Basically you add theatrical gels to your goggles to create a low-pass filter for only seeing infrared. Might make them more fun that just to wear on our foreheads.  Tongue



I am wondering if its quite as "dramatic" as seen in the video. I am going to order some filter gel sheet things and try it out.

I think even if it works, it would be very dark. But if you were to add some IR-flashlights it could be interesting. Then you should be able to see in the dark.

It's not actually real IR, but should be an interesting effect anyway, I saw a site that had some very good explanations:

So I ran to the local karaoke/party equipment shot and bought the gels. One deviation from the video (and in line with a previous url in a reply.) only use 3 blue gels and one red. And you MUST have no light leaks in the goggles.

It looks so amazing! Never seen orangish/pink grass and trees. And its MUCH more colorful than the photos posted in the previous url (results). It seems to render better in the human eye than through a camera.

Back in the 35mm film good old days, you could by black and white and colour infrared film. You slapped on a an R72 or #25 filter and shot away. The black and white was more dramatic, the sky went balck, vegetation went bright. Pics had a dreamy moonlioght effect, almost. You can do the same with some modern digicams, just depends on how they filter before the sensor.. Here's a hsot from one of the IR shooters on a Nikon forum...

That's nice, since modern analog SLRs like my trusty Canon EOS 300 (Rebel Ti in the americas) aren't IR-fillum compatible.

Ah, the EOS 300 is a wondrous camera! I am very interested in these, I do wish I could find a place in the colonies that stocks such materials.

Wondered why that would be the case, so I did a bit of reading.    It appears people who have tried IR film with EOS cameras get either no fogging in the image area, or just a very slight amount bleeding in from the sprocket counting side of the film, so if you wish to experiment, do so by all means.
I did a bit of IR photography some years back and the best piece of advice I ever read was "buy TWO rolls of film".     Your first roll will always turn out crap, and if you only bought one roll, you'll never buy another...  but if you'd already paid for the second roll then you might as well use it, and hopefully what you learnt from the first roll will improve your second roll.
The reason being, that the exposure meter on a camera no longer helps you with any meaningful information, so you have to manually expose...  and IR film isnt very tolerant of the exposure being wrong.
But good luck anyway.

I haven't tried IR + EOS, since there's a tag on the inside of the camera back saying basically "Oi, don't use IR film with this camera" and I therefore assumed that it would only be costly.

I do however have a Minolta XG9 that I plan to try on IR with some time in the future...

This is exactly what happened with my eos elanII.  The film was fogged along the bottom 20% of the frame. The camera uses an infra-red light to count the sprockets while advancing the frames and that fogs the IR film. Though I was lucky enough to still get some usable shots.

As for the dSLRs even if they have the IR cut filters, you can still use them for IR shooting it just takes longer.

Quicket way to tell if your digiicam is good for IR, is to set it to IS0 100,  take a long exposure in a low light room and point a standard TV remote at the lens and press the buttons while the shutter is open. You may see a light coming from the remote in the resulting image. If you do, the chances are that your camera will capture IR images relatively easily..

You could try one of these http://www.swpp.co.uk/trade/Retailer%20New%20Zealand.htm

Canon 300X (Rebel T2 in US, Kiss 7 in Japan) is still availble in shops, should be even in the colonies, shouldn't it? Smiley

Oh yes, I own the camera, I was referring to the coloured film that allowed near-infra-red viewing. So far, no places I've enquired have answered in the affirmative...

yeah it's like shooting E-6 process slide film with uncontrolled action...you really need to be within half of an fstop of a perfect exposure to have it come out.

I've had IR filter in my goggles for a good long time after reading the original $10 IR Goggle page linked above.  It's ace and it makes you feel like you're on another planet.  Also, some black clothing looks black while other clothing glows with an unholy red/pink glow!  Great stufff Smiley
