20D and IR Photography

This is probably a stupid question, but I need to ask it nonetheless.

 

To take digital infrared photos with a 20D all I need is a IR filter

(i.e. Hoya RM-72), correct? I aimed my IR remote control at my 20D

and the 20D picked up the IR beam.

 

Will the 20D take average to above average IR photos?

 

Thanks,

 

Todd

most digital camera have a special filter that will make IR photography impossible to make.... there is a IR version of the 20D called the 20Da that will let you capture IR photos.

I thought all digital cameras could take IR images to one degree or another. And there's a guy on Flickr who is taking nice IR photos with a so-called modified Canon 20D. I don't know what he means by "modified," but I would sure like to know.

 

You can find his images at:

you can MOD your 20D (void any warranty) or use photoshop to fake the IR look.

Here is my quick tutorial for this: http://www.escrappers.com/infrared.htm

<p>If the IR cutoff filter of the 20D is like the one in the 300D (which I suspect is true), then you *can* take IR pics.

</p>

The problem is, you need really really long exposures to compensate for the IR filter.</p>

This is a shot I took with the 50 1.8, using an RM100 filter, f/8 20 seconds on a sunny day!</p>

From what I read, the DP&S are far better in that regard. Their build-in wider DoF only helps in this regard. Consider buying a used G2 or Sony 717 for that. They sell rather cheap nowadays.

 

Happy shooting,

Hi, think you`ll find that conversion means removing the filter in front of the sensor and replace with another to change IR sensitivity this link may help

You can just about do IR on a standard 20D but its hard work and not very satisfactory. Problem is that all current digital cameras have an IR blocking filter in front of the sensor. Cheapest entry level solution is to buy a used Olympus C2020-Z which is very IR sensitive (no blocking filter) and put an IR pass filter R72 or equivalent on the lens. In reasonably good daylight you can then actually handhold and get good IR images (all be it a 2MP).

<p>

For a high quality IR solution you need to have the IR blocking filter removed on your camera. There are companies that advertise new EOS 350D's (DRebel XT)with this change made.

<p>

I took a slightly different approach - I bought a used D60 (a very underrated camera in my mind) and had the IR blocking filter over the sensor replaced with an IR pass filter (R72 equiv). This means I have a permanent IR camera which I can hand hold and I can use the viewfinder (since I don't need the visible light opaque R72 filter on the lens itself). The UK based guy that did the conversion for me also adjusts the focusing parameters to correct for IR wavelegths.<div></div>

<p>Bob briefly mentions IR in <a href="http://www.photo.net/equipment/canon/digital_rebel_xt/">this review of the DRebel XT</a> and compares its IR performance to that of the 20D.</p>

Example from D60 modified as described above.

Exposure was 1/90 f11 ISO 100 using 17-40f4 L<div></div>

Hi there,

I shoot digital infrared photography using a 300D and I have friends who shoot it with a 20D as well. The 20D is capable of shooting IR photos but the exposure time is long, you must use a tripod. <br>

Also, not all Canon lenses are good for IR photography... the list below is taken from the IR section from Clubsnap but hope it helps.

<p>

It shows which of the Canon lens are good or bad for IR photography :

FYI- David Sparer of irdigital.net is a thief! I sent him a Canon 10d to have converted to IR along with $500 cash for the fix. He never sent me anything back. He will not respond to phone calls or emails. And basically, he stole my camera along with $500 cash. BEWARE! Dana Hoff
