Selecting the DNG compression
1. In the main menu (see p. 154/246) select
DNG compression
(page 2,
IMAGE section), and
2. Select the required option in the sub-menu (
On [=compressed] /
Off [=uncompressed]).
Notes:
•The standardized DNG (Digital Negative) format is used for storage
of completely unprocessed raw picture data.
•The available compression for DNG format
– is loss-free, i.e. it does not cause any deterioration in quality
– retains all of the post-editing performed on the image data
– allows faster saving
– takes up less memory space.
•If simultaneous storage of picture data as DNG and JPEG is
selected, the existing resolution setting is used for the JPEG format,
i.e. the resolutions of the two files can be quite different.
•A high compression rate, such as with
JPEG standard, can result
in fine structures in the subject being lost or incorrectly
reproduced (artifacts; e.g. "stepped" diagonal edges).
•The remaining number of pictures shown in the monitor does not
necessarily change after every picture. This depends on the
subject; with JPEG files very fine structures result in higher
quantities of data, homogeneous surfaces in lower quantities.
RESOLUTION
The picture data can be recorded in JPEG format at four different
resolutions. This allows you to adjust the setting precisely to the
intended use or to the available memory card capacity. At the highest
resolution (which also means the largest data volume), which you
should select for optimum quality for large prints, a card can hold
significantly fewer pictures than at the lowest resolution.
Setting the function
1. In the picture parameters menu (see p. 154/246) select
JPEG resolution , and
2. Select the desired resolution in the sub-menu.
Note:
In DNG format, the resolution is 24MP, i.e. regardless of any different
setting made for JPEG format.
