Image file names begin with “PICT” followed by a four-digit file number and an mrw, jpg, jpe, mov, or
thm extension. The thumbnail images (thm) are used in camera and DiMAGE Viewer operation.
When a new folder is created, the first three digits in the folder name will be one greater than the
largest folder number on the card. When the file number in the image file name exceeds 9,999, a new
folder will be created with a number one greater than the greatest folder number on the memory card:
e.g. from 100KM020 to 101KM020.
The file number on the image file may not correspond to its frame number on the camera. As images
are deleted in the camera, the frame counter will adjust itself to show the number of images on the
card and reassign the frame numbers accordingly. The file numbers on the image files will not change
when an image is deleted. When a new image is recorded, it will be assigned a number one greater
than the largest file number in the folder. File numbers can be controlled with the file-number-memory
function in section 2 of the setup menu (p. 136).
Image files contain exif tag data. This data includes the time and date the image was recorded as well
as the camera settings used. This data can be viewed with the camera or the DiMAGE Viewer
software.
If a camera image is opened in an image-processing application that does not support Exif tags, and
then the image is saved overwriting the original data, the Exif tag information is erased. Some Exif
compatible applications rewrite the Exif data preventing the DiMAGE Viewer from reading it. When
using software other than the DiMAGE Viewer, always rename the image file to protect the exif tag
data.
To view images correctly on your computer, the monitor’s color space may need to be adjusted. Refer
to your computer manual on how to calibrate the display to the following requirements: sRGB, with a
color temperature of 6500K, and a gamma of 2.2.
Although it is recommended to format a CompactFlash card with the camera, a card can be formatted
with a computer. The card must be formatted on a Windows system using a FAT or FAT32 file system.
