✦ 3:2. This is the standard aspect
ratio used in photography. Because
the sensor is in the same aspect
ratio, this ratio uses all the avail-
able pixels.
✦ 16:9. This is the aspect ratio of
high-definition televisions. Sony is
a leader in the high-definition tele-
vision field, and with the HDMI
output on the camera, this camera
can produce high-definition images
in a native format for the 16:9 tele-
visions. Because the 16:9 aspect
ratio does not use areas on the top
and the bottom of the sensor, the
resulting image is smaller in size
than one taken using the 3:2
aspect ratio.
File quality setting
When a photograph is taken, the image is
saved to the memory card. The file format is
the type of file and the format of the infor-
mation that is written to the memory card.
The Sony Alpha A700 has seven different file
format settings.
✦ RAW. The information in this for-
mat is the RAW data that the cam-
era sensor captures.
✦ cRAW. The cRAW mode is a com-
pressed RAW mode. This file for-
mat saves space by compressing
the image 60 to 70 percent com-
pared to the regular RAW mode.
Everything else is the same as the
regular RAW mode.

the bottom show what information would not be recorded when the camera is set to the
