Newer cameras store more images in each folder, so the mathematics change.

Modulo 100 may sound frightening, but in reality it means just take the two right hand digits.

Shutter Count = (folder number-100)*100 + modulo 100 file number.Split the image number into two parts: the last 4 digits (call this file number) and the first three folder number.It shares many features with the Canon EOS 1D X.It was publicly announced on April 12, 2012, and was released in March 2013 with suggested retail price of US15,000 (body only). Thus to convert the image number to the number of shots taken we need to do the following: The Canon EOS-1D C is an 18.1-megapixel CMOS digital single-lens reflex camera (digital SLR) made by Canon in the Cinema EOS range. A twist is that looking at one of the early images I took with this camera is that the folder numbers start at 100 rather than 0. The folders each hold 100 files so the first 3 digits increment once every 100 images to reflect the new folder number while the last 4 digits increase to 9999 then rollover to 0. Under DCIM there are two folders at present: 291CANON and 292CANON. I then realised that the first 3 digits are in fact the folder number on the memory card. That makes more sense – the last image was IMG_9222.JPG. One EXIF data tool reports the number as 292-9222. On my 10D, it shows 2929222 approaching 3 million shots which is clearly wrong. The number of shutter actuations on older Canon cameras is encoded in the 'Image Number’.
