Choose the number of pixels (size) and quality level (data compression
rate) of still pictures according to how you intend to use the pictures you
have taken.
Higher quality levels and numbers of pixels produce clearer images, but
the resulting increase in data volume reduces the total number of
pictures that can be taken (stored in the camera's built-in memory or on
the SD Memory Card).
The quality of the captured photo or printed picture also depends on the
quality level, exposure compensation, resolution of the printer and a
variety of other factors, so you do not need to select more than the
required number of pixels. As a rough guide, _
(1600x1200)is
adequate for making postcard-size prints. Refer to the table below for the
appropriate settings according to use.
