Hi! I ran into a site called that does "Infrared Conversion" on Digital SLRs. Although I have NO knowledge at all about what infrared conversions are or how they work, I liked the sample pictures they had on their site. They also say this is better than putting infrared filters on your lens.

So, I was wondering if it is a good idea to send your camera to them and have them convert it. I just a bought a 40D (my wife's actually) and I don't want to risk sending it to them.

Does it affect the camera's functionality? Will I still be able to take normal pictures or will it always have the infrared effect on all pictures?

I am thinking of getting a used XT or XTi and send it to them for conversion. Will this be enough for shooting infrared pictures? How about a 5D?

woah, dont do it man! thats if you have a back-up camera kind of, you send them the back up, what the do is take the IR filter or something of your sensor and all you can shoot from there is IR shots...

Some one else, reinforce this?

why dont you jut buy an IR filter, of if you wanna do it proper, used 300d body, and converted, will work with your existing eos lenses, or :) buy a sigma sd14 body (used $400) where you can remove IR from camera in few seconds :)

That would be a very bad idea unless you want to only shoot in IR. I did it myself to an old 3.2 megapixel PS Fuji I had and it's lots of fun, but it's only good for IR now.

I took a couple of sample shots an put them on Flickr if you're curious. But, don't destroy that perfectly good 40D. Your wife will kill you.

Whew! Thank you very much! My wife will, yes, kill me if I had sent the 40D to them.

I found a couple of used XT and XTi's on-line for less than $500 so I might do that instead. Man, good thing you guys replied quickly coz' I was thinking of buying a new 5D later to send that to them and use as my back up. Didn't know it will screw up my ability to take normal pictures.

By the way, nice IR pics csrussell!

It's absolutely correct that having an IR conversion will affect the way the camera works. For the full-on IR effect the conversion gives the best results but after that has been done you would have to use an IR blocking filter, usually fixed to the front of the lens, to get back to a "normal" image.

There may also be an issue with removing the IR filter in front of the sensor if the same piece of glass also acts as the anti-aliasing filter. Sorry, but I can't remember if that is the case on the 40D.

Bottom line is that I agree that you shouldn't do that to your 40D. A used XT or XTi sounds like the way to go if you are keen to experiment.

Bad idea unless IR is the only kind of photography you are interested in. Definitely start with an XT first, that way it's cheaper if you lose interest or something goes wrong. :wink:

A Canon 5d wouldn't necessarily make a better IR camera, it is the better camera in general but for IR, I don't think anything other than the usual differences apply. Any camera can be converted to IR, even compacts(in theory) although it is much more difficult because they are sealed, I don't think a conversion service exists.

Here's a link to the guide I used to make my old compact into an IR camera. I wouldn't use this guide on an SLR, and in fact would be very hesitant to open up a DSLR period. It's best if used on a compact with slightly better manual controls than others, and shooting in black and white is also a big plus. The only thing I can control in my "Manual" mode is WB, which is why my pictures are all bluish. I find it to be at least more pleasing than the default reddish pink.
