Canon 350D/ Digital Rebel XT IR Performance (Part 1)

Infrared test.
The Canon 350D is my latest camera (owned, rather than on loan for review), so I was very curious to see what its IR performance would be.


This RAW shot was taken at 1.6 second and f5.6 at 100ISO


Red only


Green


Blue

Noise is reasonably high with this camera and shooting in IR with a Hoya R72 filter.

Below are 100% sections of an image:


Red


Green


Blue


Despite the noise, the 350D is capable of returning some lovely IR images. Exposure was 0.3 second at F2.8 and 100ISO.


Exposure 1 second at f5.6 and 100ISO


From the red channel only. Exposure was 15 seconds at f5.6, 100ISO in rain.


Or the green channel


1 second at f8 and 100ISO

A followup article explores 350D performance with varying ISO.

  1. Greetings!
    I found your web page very useful for IR settings, however I would still like to ask regarding one issue:
    At the very first tries I had done at home taking shots from my window (exposure needed quite long,indeed) and I get pinkish image (I didn’t adjusted white balance as I’m not sure how to do that yet), do I proceed this pinkish raw image in photoshop later to remove blue and green channels so that only red is left for those fancy pictures with white grass and black sky? Or is there any settings such as perhaps adjusting white balance on dslr (i work with Eos 50D, filter is Hoya 72) that can take visible shot on lcd camera monitor without editing it on computer? I mean is the pinkish image – natural original that will later be edited and turned into high contrast bw infrared? I haven’t found out yet how to adjust colour balance for colour IR photography but I will try,surely…
    I would appreciate your reply.
    Thanks for attentnion,
    -M.

    I shall do some white balance adjunstments on green grass shots, as I indeed want to make some full spectrum images such as those involved with IR, HDR and soft fancy colours. Usually I used to produce fake IR on photoshope using individual adjustments for each color channels too, however I always was interested and now I’m glad to have a chance to work with it!
