• Standard File Number Assignment
Method
The camera records the number of the
last image that was recorded. When an
image is next shot, it adds one to the
previous number to create the new file
number. However, if there are images
already on the CF card that have higher
file numbers, the camera adds one to
the highest number on the CF card to
avoid duplication. This means that a
particular camera will not create two
images with the same file number. As a
result, the file numbers on a particular
CF card may not be consecutive if other
cards have been used in between
recording sessions with that card.
