The file name is edited to lower the numerical suffix.

If a blank flash card is inserted afterwards, some cameras like the Canon 60D will continue previous filename numbering for example, will write file IMG_4102.JPG when shutter count is 3752.The shutter count in this case will be only 3751. If a new flash card is inserted with a file IMG_4100.JPG, then the next picture taken with the camera will be written under IMG_4101.JPG. The numbering then continues with this higher suffix.įor example, if the last file written by the camera was IMG_3750.JPG, this indicates that the shutter count is 3750.
