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.
