+
+ <para>This is commonly the native format of digital cameras,
+reflecting the arrangement of sensors on the CCD device. Only one red,
+green or blue value is given for each pixel. Missing components must
+be interpolated from neighbouring pixels. From left to right the first
+row consists of a green and blue value, the second row of a red and
+green value. This scheme repeats to the right and down for every two
+columns and rows.</para>
