ResolutionThe picture data can be recorded in JPEG formatwith five different pixel settings, i.e. resolutions.This allows you to adjust the setting precisely tothe intended use or to the available memory cardcapa c ity.At the highest resolution (which also means the largestdata volume), which you should select for optimumquality for larger prints, it is of course possible tosave considerably fewer pictures to a card than atthe lowest resolution, which is perfectly adequatefor sending a picture by e-mail or for a website.Note:Raw data (DNG, see next section) is always saved withthe highest resolution.Setting the function1. In the image parameters menu (see p. 103/119),select Resolution (4.2.3), and2. the desired resolution in the sub-menu.Compression rate/file formatThe picture data can optionally be recordeda. with one of two different JPEG compression rates –JPG fine/JPG basic, orb. using the DNG file format, either Uncompressed orCompressed, orc. using combinations of one of the two JPEG compressionrates and the set DNG format, i.e. twofiles are generated per picture. In these cases theJPG file will always be saved with the selectedresolution.On the one hand this allows exact adjustment for theintended usage and the available memory card capacity,and on the other hand provides security and flexibilityessential for subsequent decisions on usage.Setting the functionA. Selecting the DNG format1. In the main menu (see p. 102/119) selectDNG setup (4.1.19), and2. the desired option in the sub-menu –Uncompressed or Compressed.B. Selecting the JPEG compression or formatcombination1. In the image parameters menu (see p.103/119), select Compression (4.2.2), and2. the desired compression/combination in thesub-menu.Notes:• The standardized DNG (Digital Negative) format isused for storage of completely unprocessed rawpicture data.• The Compressed format includes a slight compression,which– causes only a negligible deterioration in quality– provides full scope for subsequent processing ofthe picture data– allows faster saving– takes up less memory space.• With the raw data setting (DNG) the resolution isset automatically to (18MP), regardless of theexisting setting (for the relevant JPEG format) (seeprevious section).• With simultaneous storage of picture data as DNGand JPG, the existing resolution setting is used forthe JPEG format, i.e. the two files can have totallydifferent resolutions.• A high compression rate such as with JPG basiccan result in very fine structures in the subjectbeing lost or incorrectly reproduced (artifacts; e.g.“stepped” diagonal edges).• The remaining number of pictures shown in themonitor does not necessarily change after everypicture. This depends on the subject; with JPEG filesvery fine structures result in higher quantities ofdata, homogeneous surfaces in lower quantities.125
