| ->> I don't think there is anyway of knowing. I know there is a program to figure out the 1D series, but I haven't seen anything for the 20D. |

->> I think that information is usually embedded in the exif info of a picture taken with the camera. I use a program called exif viewer (this might be it, not sure though: http://homepage.mac.com/aozer/EV/) and that shows me all the information i need. The information should be common no matter what kind of camera you use.
Try that. Good luck. |

->> I downloaded a program and it lists the number of acuations as this:
Camera Actuations: 427884581
So which would be the actual number among this group? |

->> Jeff,
I use a program from a company called Opanda. Here is the link
http://www.opanda.com/en/iexif/index.html
I shoot Nikon and it works great. I am not sure how it will work with Canon. It only will read the actuations on Jpeg's also, not RAW files.
Hope this helps.

| ->> I got the acuations number from EXIF viewer, but don't know what the numbers mean or what sequence I should be looking. They are listed above. Can anyone help on this? Jeff |

->> Jeff,
It's pretty obvious the EXIF viewer isn't interpreting the values in the data correctly for the 20D. EXIF info seems to change with each new camera. Though there is some standardization, there are holes in the standard.
The value for the actuations is really the result of two numbers, but the software is using the wrong two. That's a common problem when programming and dealing with "kinda-standards".
My brain is a sieve these days, but I'll try to remember to dig out my software when I get home and see if I can't make some sense of it.
BTW, are you sure you didn't fall asleep with your finger on the shutter release one night? :-) |

->> I looked at the program, then at the underlying program it was built on. It's built on some Windows/Unix code called exiftags.
I opened the source-code for exiftags and found a couple things.
1 - It's aware of 1D and 1DS settings. It could be updated, but that's a lot of work.
and B - the value is based on two numbers embedded next to each other in the EXIF header in a manufacturer-specific block, kind of like their own sandbox. They get to use it for whatever they want. In Canon's case, the first number has to be multiplied by 65535, then added with the second number.
The problem is, if Canon (or any other manufacturer) adds some information ahead of that data location in their sandbox, then all the other following numbers and data will be off. And, there's nothing to keep Canon from doing that. (Well, except for maintainability and consistency, but those are programmer concerns.)
This leads to a conversation I had with one of the programmers for one of our favorite photo browsers, where we (the computer-nerd photographers) could define the locations of the vendor-specific data in an image using a truly standard data definition language (XML), and the app would use that to decode the info. There's too many changing vendor-specific EXIF implementations for any one company to do it, but they could leverage their loving customers to provide the necessary slave labor to figure out those fields. |

->> Jeff,
Fire off a shot, and see if the counter goes to 427884582. Just a thought. Maybe you can see the pattern by shooting a shot at a time and seeing how the number increases. It might also show that it's incorrect if the number just goes haywire. |

->> I downloaded the IEXIF 2 software from Opanda and spent a couple hours yesterday trying to figure out the actuations on my 30D. I shot a series of about 50 jpgs and looked for a pattern in Field 93. I definitely found a pattern, but it doesn't tell me much. When I went back to one of the very first photos I took with that body, I tried to apply what I thought I learned from the pattern and as it turns out I have a little over 529,000 actuations since I got the body in March. Hmmm I don't think so.
On the bright side, installing the software does give you a right-click option (on Windows) to view EXIF summary information for any image on your computer or online (provided the image has EXIF info.) I'm having fun surfing around and seeing what cameras and settings were used on different photos on the web, in e-mail attachments, etc. |

->> David,
I'm pretty sure that Photo Mechanic lists acutations for 1d seires bodies.
However, when you view the Frame# in photo mechanic on a 20d/30d ect. it lists it a little funky. These cameras make folders so the first 3 numbers are the folder #. Then, there is the image # within that folder. It is something like that. I'm not sure exactly how it works or if the program you are using displays the numbers the same way.
