Here is a non-official way (do-it-yourself-at-home) on the forum to map out dead pixels on Canon EOS 5D.

Make a shot with lens cap on at eg. 1/5 seconds and 1600 ISO with auto-focus off (or turn off noise reduction in CF and make shutter open for longer). After that go to Sensor Cleaning and turn it on (as cleaning the CMOS when mirror is up and shutter is open, but leave lens on) for a minute. Yes, it should be long enough. After that, switch camera off, then - on and - YOUR DEAD PIXELS ARE GONE!

Since I got my first digital camera, I have been enjoying the adventure of taking IR pictures. I was amazed by how easy an image due to the invisible IR light could be seen right there on the LCD panel, and was further amazed by how striking it could turn out to be after some straightforward post processing.

What I have been experimenting with shooting IR is, however, toward the opposite direction of the traditional IR avenue while retaining its fantasy. I do appreciate the attractiveness of an IR image by its well recognized dreamy appearance. On the other hand, I also found out that an IR image can appealingly wake the viewer up by the possibility of great clarity and crisp sharpness …..full article.
