ReSOLUTION
The picture data can be recorded in JPeG format
with five different pixel settings, i.e. resolutions.
This allows you to adjust the setting precisely to
the intended use or to the available memory card
capa c ity.
At the highest resolution (which also means the largest
data volume), which you should select for optimum
quality for larger prints, it is of course possible to
save considerably fewer pictures to a card than at
the lowest resolution, which is perfectly adequate
for sending a picture by e­mail or for a website.
Note:
raw data (dNG, see next section) is always saved with
the highest resolution.
Setting the function
1. In the image parameters menu (see p. 103/119),
select Resolution (4.2.3), and
2. the desired resolution in the sub­menu.
COMPReSSION RATe/FILe FORMAT
The picture data can optionally be recorded
a. with one of two different JPEG compression rates –
JPG fine
/
JPG basic
, or
b. using the DNG file format, either Uncompressed or
Compressed
, or
c. using combinations of one of the two JPeG com­
pression rates and the set
DNG
format, i.e. two
files are generated per picture. In these cases the
JPG file will always be saved with the selected
resolution.
on the one hand this allows exact adjustment for the
intended usage and the available memory card capa­
city, and on the other hand provides security and flexi ­
bility essential for subsequent decisions on usage.
Setting the function
A. Selecting the DNg format
1. In the main menu (see p. 102/119) select
DNG setup (4.1.19), and
2. the desired option in the sub­menu –
Uncompressed
or
Compressed
.
B. Selecting the JPeg compression or format
combination
1. In the image parameters menu (see p.
103/119), select Compression (4.2.2), and
2. the desired compression/combination in the
sub­menu.
Notes:
• The standardized DNG (Digital Negative) format is
used for storage of completely unprocessed raw
picture data.
• The Compressed format includes a slight compres­
sion, which
– causes only a negligible deterioration in quality
– provides full scope for subsequent processing of
the picture data
– allows faster saving
– takes up less memory space.
• With the raw data setting ( DNG ) the resolution is
set automatically to (18MP), regardless of the
existing setting (for the relevant JPeG format) (see
previous section).
• With simultaneous storage of picture data as
DNG
and
JPG
, the existing resolution setting is used for
the JPEG format, i.e. the two files can have totally
different resolutions.
• A high compression rate such as with JPG basic
can result in very 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.
