set scan settings (Continued...)
notice:
Higher scanning resolutions result in greater scanning time and hardisk space
requirements.
b. Color depth
Choose between 8 and 16bit. a higher color depth setting will result in
a larger range of colors in the final scanned image.
the Film scanner color depth is 48 bit true color. the scanning software has the
capability of selecting 8 bit color mode or 16 bit color mode when scanning,
this will produce 24 or 48 bit color images, 8 bits or 16 bits per red, Green and
Blue color channels.
Example:
8 bit mode = 8 red, 8 Green, and 8 Blue for a total of 24 bit color
16 bit mode = 16 red, 16 Green, and 16 Blue for a total of 48 bit color
scan mode – normal mode produces a scan in jpeg format while Quality pro-
duces a non-compressed, "loss-less" tiFF image.
nOTE:
make sure there is enough space available
on the computer when changing the scanning
resolution. a high scanning resolution results in
large files that may prove difficult to save.
