Frame counter on a 1D?

| ->> How can I tell how many shots I've taken with my 1D other than sending it back to Canon? I've heard of some software programs being able to read the EXIF data to determine this. Anybody? |

->> Please tell those of us with the same question who have not had time to figure it out.... (I assume you are talking about TOTAL shots, not just the frame counter.)
Thanks! |

->> The info on Fred Miranda's site is *almost* correct. The EXIF data in question is stored as 16-bit numbers, which means the biggest number possible is 65535.
You must actually look at *two* numbers, then do some math:
Unknown (0093)3,9: 18,Y,XXXXX,0,0,0,65535,65535,0
If Y = 0, then count = XXXXX. But, if Y > 1, then count = ( Y * 65536 ) + XXXXX. (In other words, Y is a "rollover" counter that increments every 65536 shots.)
I have tested this with two 1D bodies, and it seems to be reliable. FYI, this is a shutter actuation counter, and it increments even if there is no CF card installed, or when shooting tethered, and is not affected by any type of file number resetting. I *haven't* checked to see what happens if you pull the backup battery, but I imagine that would clear the counter.
I am working on writing a command-line app that will read this data out for you (instead of using the EXIF reader, searching for data, and doing math). It hasn't been a priority lately, but if there's enough interest, I'll finish it. Place your "please finish it" vote by sending me an e-mail through my member profile :) |

->> Reading the Fred Miranda thread then Nelse Hansen's post made me laugh. I bought my first Miata in 1993. Mazda really built a great car, and I drive about 20k miles/year. Needless to say, I'm always shocked when I find someone with "95 Miata with 42,000 miles on it". I mean, it's a freaking $15k car - drive it!. Reading about someone with Canon 1D with 400 shots gives me the same feeling. Get out there and shoot!
I just checked and recent images of the 1D that went into service last January that I share with another shooter show the counter at just under 110k. Not bad for a year's use, but I'm sure some of you guys have some frighteningly high totals. |

| ->> I need help. I need to find out how many shutter actuations i have on my 1d. I have downloaded these programs and can't find it. Can someone help me out? |

->> One thing to note and I'm not sure if it's been mentioned before, but I took my 1D in for a clean/check at Canon and it came back with the "actuations" reset to zero.
So if you are buying a camera, you can't rely on the actuations in the exif data.
