•The data on your SD Memory Card should be managed at your own risk.
Recorded Pixels and Quality LevelWhen the File Format is JPEG
Choose the number of recorded pixels (size) and quality level (JPEG data compression rate) of pictures according to how you intend to use the pictures you have taken.
Pictures with larger recorded pixels or more stars (E) are clearer when printed. However, the number of pictures that can be taken (the number of pictures that can be recorded on an SD Memory Card) decreases with larger file sizes.
The quality of the captured photo or printed picture depends on the quality level, exposure control, resolution of the printer and a variety of other factors so you do not need to select more than the required number of pixels. For example, to print in postcard size, i(1728×1152) is adequate. Set the appropriate recorded pixels and quality level depending on how the picture will be used.
