Infrared with canon eos 10/20d

What is the best IR filter to use with a Canon EOS 10/20d body?

 

Thank you

I would suggest IR filters from Harrison & Harrison. The IR filters they manufacture are the 89-B, 88-A and the 87. All three filters in 77mm are $59.45 each.

Good luck!

With the 10d (I'm not sure about the 20d), there is an issue with

"hotspots" showing up in the photos when certain lenses are

used. See this forum for more details:

That being said, I think the Hoya R72 works great with the proper

lens.

I've read on forums that you can and can't get the 10D or 20D to do IR. I also had one pro

camera shop tell me flattly that the 10D would not do IR. So I did some testing.

 

I bought a Hoya R72 filter. I did some test shots today with a 28-70mm f2.8 L lens on a

20D that I just got.

 

The attached photos show the results. Not a great photo, but it demonstrates that the 20D

can, in fact, produce an IR image. The "a" version is right out of the camera, resized, but

otherwise unedited. The "b" version is after conversion to B&W (using the red channel only

in the channel mixer) and cranking up the contrast.

 

This was shot with the 28-70mm f2.8 L, ISO 400, 30 second exposure at f5.6, using a

Hoya R72 filter. It is pretty washed out, which I expect is the result of shooting on a cool

overcast day (in fact, it was drizzling slightly as I shot this).

 

This obviously required a tripod. With IR film under proper conditions, you can get fast

enough to hand hold it. But with most DSLRs, there is a filter that filters out most IR and

UV light (otherwise you'd get some pretty strange photos). Only a small amount of IR light

gets through to the sensor. Thus, it requires a longer exposure to get anything to register.

This may be why some people state it can't be done. If you handheld a shot at, say, 1/60th

second, you would just get a blank image. The shutter wouldn't be open long enough for

anything to register on the sensor.

 

The nice thing about the DSLR is that you can just experiment with different combinations

of ISO, shutter speed, and aperture until it works. Regular metering doesn't work at all

with an IR filter on.

 

On a bright sunny day, I imagine I could get away with a faster shutter speed, as more IR

rays are available for capture. Usually in IR photos on a clear day, foliage is very light (as it

mostly is in this sample), and the sky in nearly black.

Here is the same image, post processed to B&W

That is pretty cool Scott. Thanks.

I do IR with the 10d on a regular basis. You can see my portefolio for picture. <br>I use hoya 58mm R72 on the 50mm f1.8 and the Zenitar 16mm. I particuly like <a href="http://www.photo.net/photo/2720157"> this one </a><div></div>
