In-Depth Information
If you want the best qual-
ity pictures always make
sure that your scanner or
camera captures in 16 bit
per channel or 48-bit
mode. On most cameras
this is referred to as the
'TIFF' or 'Raw' setting.
The Raw advantage
The real advantages of editing and enhancing at the raw stage are that these changes
are made to the file at the same time as the primary image data is being converted
(interpolated) to the full color picture. Editing after the file is processed (saved by the
camera in 8 bits per channel versions of the JPEG and TIFF format) means that you
will be applying the changes to a picture with fewer tones and colors.
A second bonus for the dedicated raw shooter is that actions like switching from the
White Balance option selected when shooting, to another choice when processing, are
performed without any image loss. This is not the case once the file has been processed
with the incorrect White Balance setting, as anyone who has inadvertently left the
tungsten setting switched on whilst shooting in daylight can tell you.
