C.Fn IV -3 Add image verification data
0: Disable
1: Enable
Data for verifying whether the image is original or not is appended to the
image automatically. When the shooting information of an image
appended with the verification data is displayed (p.167), the icon
will appear.
To verify whether the image is original, the Original Data Security Kit
OSK-E3 (sold separately) is required.
C.Fn IV -4 Add aspect ratio information
During Live View shooting, vertical lines corresponding to the aspect ratio
will be displayed. You can thereby simulate framing for medium- and large-
format film sizes such as 6x6 cm, 6x4.5 cm, and 4x5 in.
This aspect ratio information will be appended automatically to the captured
image. (The image will not actually be saved to the memory card as a
cropped image.)
When the image is transferred to a personal computer and the Digital Photo
Professional (provided software) is used, the image will be displayed in the
aspect ratio you specified.
0: Off
4: Aspect ratio 6:7
1: Aspect ratio 6:6 5: Aspect ratio 10:12
2: Aspect ratio 3:4 6: Aspect ratio 5:7
3: Aspect ratio 4:5
The images are not compatible with the image encryption/decryption
features of Original Data Security Kit OSK-E3.
Aspect ratio information will also be appended if you shoot through the
viewfinder.
During image playback on the camera, vertical lines for the respective
ratio will be displayed.
