BASIC PICTURE SETTINGS
File format
Two file formats are available for recording the picture data
DNG and JPEG.
You can select, whether your picture data
a. is to be saved in only one of these formats, or
b. simultaneously in both (i.e. two files are always created for each
picture).
Setting the function
1. In the
IMAGE menu (see p. 16/26), select File Format (5.10), and
2. then the required format(s) or combination in the submenu.
Notes:
• The standardized DNG (Digital Negative) format is used to store the raw
picture data.
• The remaining number of pictures shown in the monitor does not necessar-
ily change after every picture. This depends on the subject; with JPEG files
very fine structures result in higher data volumes, homogeneous surfaces
in lower volumes. The details in the table are based on an average file size
for the set resolution. The file sizes are often smaller, depending on the
picture content and the compression rate, which means that the remaining
memory capacity is then greater than previously calculated and displayed.
Compression rate
You can select different compression rates independently for the two file
formats. For
DNG format, totally loss-free compression of the picture data or
uncompressed recording are available, while for
JPEG format, you can select
JPEG fine
or JPEG basic.
Setting the function
1. In the
IMAGE menu (see p. 16/26), select DNG Compression (5.11), or File
Format
(5.10), and
2. then
Off or On and the desired compression rate in the relevant submenus.
Note:
A high compression rate such as for
JPEG basic can result in very fine
structures in the subject being lost or incorrectly reproduced (artifacts; e.g.
"stepped" diagonal edges).
JPEG resolution
While in
DNG format the full resolution of 37.5MP is used, with the JPEG for-
mats you can also use two lower resolutions.
Setting the function
1. In the
IMAGE menu (see p. 16/26), select JPEG Resolution (5.12), and
2. then
37.5MP, 9.3MP or 2.3MP in the submenu.
