How to check shutter count..........

[roanjohn]

On the Rebel??? :?

Anyone??

Count? meaning what? speed? number of times released? If you enabled continuous numbering, your file number count should be close enough for gov't. work on total releases. For shutter speed, one home standby's been photographing a TV screen and seeing how big the illuminated band is (NTSC refreshes at 30 frames/sec., so anything under 1/30 sec should show a diagonal band proportional to the shutter speed)..

I mean.........how do you check how many pictures you've taken........??

If you've got continuous file numbering turned on, the folder (100CANON, etc.) and frame (IMG_0001.JPG) will give you the count. Folder count starts at 100, so subtract 100 from that number and add 4 zeroes at the end to get the 10000s place. The frame name (0001) gives you the number of frames (to 9999, when the folder comes into play) you've taken. So, \DCIM\293CANON\9346.JPG would be photo #19346. Last 2 digits on the folder and first two in the file should match unless someone's been sending files all over.

This all relies on:
1) keeping continuous frame numbering turned on and
2) not (inadvertently or otherwise) inserting a card from someone else's camera, which will throw off the tally
It also presupposes you don't spend a whole lot of time clicking the shutter with no card in the camera.

I assume that using multiple cards (exclusively in one camera) does not throw off the numbering/count??

Thanks.......!!!............

Not if you're using continuous numbering. If you've opted for file number reset, it'll start over every time you put a clean card in.

When I bought my D-Rebel, I noticed the photo numbers were already in the hundreds. This led me to believe I had got a used camera. I returned to the store and looked at another Rebel. Same thing. Just a slightly different number.
I e-mailed Canon and asked if there was a way to find out how many photos the camera has taken. They assured me there was absolutely no way of knowing.
So Jon's math would even be useless as there is already a count on the camera. You would have to physically keep count from day one how many times the shutter has been actuated.

AYA!!! They should implement something.........

I agree! :x

It would really be helpful. In my case, I mixed up the CF cards between my two 10Ds, and instantly my new 10D had about 3,000 shots on the counter.

I mean.........how do you check how many pictures you've taken........??

What you probably saw was a camera that had been pulled out of the box for a potential customer, who shoved his own card in there while testing. After you walked out with it, they started using the other one as display model. Either that or they keep a CF card around to use in their demonstrator. If you got an unopened box, the count should have been zero. Sort of like buying a car off the lot.

You will notice the question was "how many pictures you've taken", after I asked for the clarification and included "number of times the shutter's been released" as one of the options. This method will allow you to determine how many pictures you have taken, i.e. committed to chip. If someone else used the camera before, or you did a lot of dry-firing with no card in this won't match, exactly, the number of times the shutter's been fired, but unless you got a fairly-well-used camera, should be close enough to reality for anyone's purposes.

But knowing how the numbering works, you can reset the values as needed by creating a file at the correct number settings, loading it into the camera while temporarily enabling file number reset, and then re-enabling continuous numbering.

I will assure you that neither camera checked was a demo or had been previously opened. I challenge you to take a look the next time you are in a store. This is something that I have researched extensively.

Keep all your raw files, count them, divide by two ;-)

I only shoot JPEG!!! :twisted:

Well then you dont have to divide by two.

Even when i'm shooting in JPEG (which is becomeing more frequent lately) i keep the "raw" image. (raw as in untouched jpeg, not a .raw file).

Ahhh!! As in the "JPEG negative".
