To record raw, unprocessed data from the camera image sensor, select a RAW option for image quality in the shooting menu as described below. JPEG copies of RAW images can be created using the RAW CONVERSION option in the playback menu, or RAW images can be viewed on a computer using the RAW FILE CONVERTER EX 2.0 application.
Press MENU/OK in shooting mode to display the shooting menu.
Press the selector up or down to highlight IMAGE QUALITY and press MENU/OK.
Highlight an option and press MENU/OK.
Select RAW to record only RAW images, or FINE+RAW or NORMAL+RAW to record both JPEG copy together with the RAW images. FINE+RAW uses lower JPEG compression ratios for higher-quality JPEG images, while NORMAL+RAW uses higher JPEG compression ratios to increase the number of images that can be stored.
Sensitivities of L (100), H (12800), and H (25600) are not available when RAW image quality is on.
The Fn Button
To toggle RAW image quality on or off for a single shot, assign RAW to the Fn button. If a JPEG option is currently selected for image quality, pressing the Fn button temporarily selects the equivalent JPEG+RAW option. If a JPEG+RAW option is currently selected, pressing the Fn button temporarily selects the equivalent JPEG option, while if RAW is selected, pressing the Fn button temporarily selects FINE. Taking a picture or pressing the Fn button again restores the previous setting.
