Basic picture settings

File format / Compression rate

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,

b. Simultaneously in both (i.e. two files are always created for

each picture),

AND

c. in the case of JPEG format, which of two compression rates -

JPEG fine or JPEG standard - you want to use.

Setting the function

1. In the IMAGE section of the menu (see p. 13/22), select

File Format (5.10), and

2. Select the required format(s) or combination and the com-

pression rate in the submenu.

Notes:

• The resolution is always 37.5 MP, regardless of the for-

mats/compression rates used.

• The standardized DNG (Digital Negative) format is used for

storage of completely unprocessed raw picture data.

• A high compression rate such as for JPEG standard can

result in very fine structures in the subject being lost or incor-

rectly 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.

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.
