Is it possible to modify the 300D to greatly enhance se

It is possible to modify the 300D (as well as most other DSLRs) to greatly enhance sensitivity to long distances objects:

Is true?Did someone do like this?:confused:

IR photography is not "enhancing sensitivity to long distance subjects"...
It IS possible of course to remove the IS filter, but then you do have to know what you are doing photography wise, and you do have to use an IR filter on your lenses for normal photography!!

hmm, i'm guessing you mean that the IR wavelength isn't really affected by atmospheric haze and therefore images come out clearer over long distances. well, i find that to be pretty consistent with the IR images i've shot. you don't have to go modifying your camera to shoot IR, you can just use an IR filter but it requires long exposures and adjustments to the focus. check your private messages as i sent you something.

This is confusing.... an IR filter gets rid od IR... so how can using an IR filter give you IR photography... you indeed need to remove the IR filter in front of the sensor for best results, but then you need to use an IR filter in front of the lens to be able to use your camera normally.

ah, it's just the wording. i forget what the technical term is for the filter built into the camera that BLOCKS IR. anyways, it's different from what i call an IR photography filter that blocks out VISIBLE light and allows the sensor to capture the IR light without being over powered by visible light.

if i understand it correctly, the IR blocking filter is put in place by the manufacturers because the sensor is sensitive to IR wavelengths but that IR light can an unwanted effect on the image. when a camera is modified (standard/common type of modification) for IR photography, the IR blocking filter is removed so the camera is more sensitive to IR so that faster shutter speeds can be used. to take an IR image, the IR filter that allows IR wavelengths to pass but blocks visible light needs to be used. to take a normal picture with an IR modified camera an IR BLOCKING filter needs to be used or the image may come out with some funky colors.

You're spot-on ReF.

I used to a bit of IR in my film days - mainly on my large format camera.

It's really cool stuff. I bought an IR filter (which cuts out the visible spectrum) and it's visibly opaque! It looks like a lens cap!

Here's a result from 4x5". It's not a great scan (buying a new scanner as we speak - haven't forgotten you Pete) but I have a 16x20" print of this image at home and it's stunning:
