[APML]: scan test results -- Microtek ScanMaker 35t Plus

[Cameron Tully-Smith <shareimg@wco.com>]

Scanner: Microtek ScanMaker 35t Plus using the Windows scanner software.

All images: gray CCD filter: Green (which is the one that 
Microtek selects by default).  Maximum optical resolution of this
scanner is 1950dpi.  Auto contrast was turned off unless otherwise
noted (this is the default for the Microtek scanner software).

The images are available at
http://www.wco.com/~shareimg/apml/scantests/microtek35tplus/
with the following filenames:


targetgrayscalenormalcontrast1950dpi.gif

Scanned with default scanning values by resetting scanner
software.  Scanned at 1950dpi as a straight positive
and saved directly to GIF format.


targetgrayscalemaxcontrast1950dpi.gif

Same as targetgrayscalenormalcontrast1950dpi.gif except that
the contrast option in the scanner software was set to 100%.


targetcolor1950dpi.tif and targetcolor1950dpi.jpg

Scanned as a straight positive with the default scanner
software settings.  Color correction was turned off
(it is turned on by default).  Scanned at 1950dpi with the
"millions of colors" option and saved directly to TIFF 
and JPEG, respectively.  The JPEG version was saved with
the highest quality (lowest compression) available.  The
TIFF version is uncompressed.


testnegnormalcolor800dpi.jpg

Scanned as a negative at 800dpi.  Saved with a compression
level of 15 (with 1 = least compression and 99 = most compression).
Scanner software was reset to its default settings and then set to
a film type of Gold II 100 (the negative is Gold 400, and I've
found that my scanning results are generally better with any Gold
or Royal Gold film if I use this setting) and an exposure correction
one notch to the left of center (resulting in a darker final scan).


testnegnormalcolor400dpi.jpg

Scanned at 400dpi with the gray CCD filter set to gray (instead
of green).  Otherwise the same as testnegnormalcolor800dpi.jpg.


testnegnormalcolor400dpi2.jpg

Exposure correction set to two notches to the left of center.
Otherwise the same as testnegnormalcolor400dpi.jpg.


m8negcolor1950dpi.jpg

Scanned as a negative at 1950dpi with the "millions of colors"
setting.  The scanner software was
set to the defaults.  Saved at a compression level of 1 (least
compression) and a "save at DPI" setting of 1950.  gray CCD
filter was set to "gray."


m8negbandw1950dpi.jpg

Scanned as a negative at 1950dpi in 256 shades of gray.
Otherwise the same as m8negcolor1950dpi.jpg.


m8negbandw1950dpi2.jpg

Exposure time setting: -18%; brightness setting: 21%.
Otherwise the same as m8negbandw1950dpi.jpg


m8negbandwcolor1950dpi.jpg

Scanned as a color positive with the "millions of colors"
setting.  Scanner software set to default settings.
Saved at a compression level of 1 (least compression) 
and a "save at DPI" setting of 1950.  gray CCD
filter was set to "gray."


m8negbandwcolorreversed1950dpi.jpg

Negative image of raw data for m8negbandwcolor1950dpi.jpg
(that is, before exiting, so reading a JPEG before manipulating
it was not involved).


ngc7000color400dpi.jpg

Scanned at 400dpi.  Scanner software set to defaults.
gray CCD filter was set to "gray."  Didn't change
the settings at all.  Saved with a "DPI to save" setting
of 400 and a compression level of 15.


ngc7000color400dpi.jpg

Changed settings in scanner software to match Chuck's
scan as best I could without tons of back and forth.
Otherwise the same as ngc7000color400dpi.jpg.
