Scanning either slides or negatives has been found to require rather
|
||||
large gamma corrections of about 2.2 to 2.4 (same value for red, green,
|

and blue). Also, for slides, using "Auto Exposure" helps a lot.

and blue). It is recommended to use the automatic exposure controls
|
||||
of the front end xsane for best results.
|
||||
.PP
|
||||
The "Auto Exposure" function for slides makes the scanner do a first
|
||||
pass on the film to determine the Highlight and Shadow point
|
||||
values. The "Auto Focus" function triggers yet another pass to
|
||||
determine the focus value. After that, the real scanning pass takes
|
||||
place. The "Auto Exposure" function is not available for negatives yet.
|
||||
The "Auto Focus" function triggers a special pass to determine the focus
|
||||
value. After that, the real scanning pass takes place.
|
||||
.PP
|
||||
Even with "Auto Focus" turned on, the scanned image is often a bit too
|
||||
blurred. Using the GIMP to do a "Filter->Enhance->Sharpen" at about 40
|
||||
to 60 improves the image considerably. It is likely that a sharpen filter
|
||||
will be included in a future version of this backend.

The "native" scanner resolutions of the 2700F are the integer
|

sub-multiples of 2720 dpi, i.e. 1360, 680, 340 and 170. Scanning at
|
||||
other resolutions is possible, but there will be noticeably more jaggies
|

in the image than when using one of the "native" resolutions.

Gamma corrections are done not by the scanner, but by the backend.
|
||||
The scanner is always run in 12-bit mode. In "color" mode the image
|
||||
data are corrected for gamma, shadow point, etc., and then truncated
|
||||
to 8-bit intensities; the default gamma value is 2.5. In "raw" mode the
|
||||
to 8-bit intensities; the default gamma value is 2.0. In "raw" mode the
|

image data are exported without corrections as 16-bit intensities; this
|
||||
mode can be recommended if extensive adjustments have to be made to a
|
||||
picture (and if the frontend can handle 16-bit intensities).
