I have a Canon 20D and would like to know how many picture has been taken with it. Is there a way, and could you describe how to go about it.
Thanks

correct me if I am wrong, but I don't think that program will tell you how many shutter actuations your camera has had. If I'm not mistaken, there is no real way to tell on the 20D.

Caboose is correct, the information is not present in the 20d's exif.
Canon decided to not make the shutter activation information available in their non pro bodies.

It can be read in the 1d series image information, and a Canon Service Center should be able to get the information out of the 20D camera with their diagnostic bench.

Ohhh, interesting find :!:
I'll have to try that when I scurry home.
So far nothing I've tried has been able to find the count.

I know approximately how many images my 20D has taken, and I shoot raw, so I should be able to verify if the number is anywhere close to what I think it should be.

Drat I was really hopeing it would work but unfortunately no go
Here are some values I got using the XVI32 hexeditor, includeing for the very first image I took out of the camera.
The field is changeing but does not show much pattern.

Code:

$95d  actual
value image
6401  0001

7400  1512
7401  1513

8943  3823
8944  3824
8945  3825
8946  3826

Do you by any chance have the 95D,95E value for image 1511 ? I'm curious to see what happens to "7400" minus one image.

Interesting but still can't make out a pattern for the jumps.
This exercize did show me I really need to stop keeping too much, and go purge old bad images :?

Code:

Actual $95d
