The D7500 supports the following image quality options:
Image quality can be set by pressing the X (T) button and rotating the main command dial until the desired setting is displayed in the information display.
Image quality options with a star (“”) use compression intended to ensure maximum quality; the size of the files varies with the scene. Options without a star use a type of compression designed to produce smaller files; files tend to be roughly the same size regardless of the scene recorded.
NEF (RAW) Images
Selecting an NEF (RAW) option fixes image size at Large. JPEG copies of NEF (RAW) images can be created using Capture NX-D or other software or the NEF (RAW) processing option in the retouch menu (0 NEF (RAW) Processing).
When photographs taken at NEF (RAW) + JPEG are viewed on the camera, only the JPEG image will be displayed. When photographs taken at these settings are deleted, both NEF and JPEG images will be deleted.
The Photo Shooting Menu
Image quality can also be adjusted using the Image quality option in the photo shooting menu (0 Image Quality).
For information on the number of pictures that can be stored at different image quality and size settings, see “Memory Card Capacity” (0 Memory Card Capacity).
