Wide Area Transparency - Epson

Postby IanBarber » Tue Apr 05, 2016 10:24 am

I believe the wide area transparent option is used for scanning negatives which are placed directly onto the scanner glass.

Does Silverfast AI use the entire glass area or just a portion of it. If it just a portion, does anyone know what that area is

Dear customer,

SilverFast offers the full scannable area.
There is a small strip at the edge of the glass that cannot be reached by the sensor and the calibration area can not be used for scanning.
Your scanner comes with a "scan area guide" that can be placed on the glass to indicate the scannable area.
For some devices this is a black plastic foil "frame" and for some a black plastic piece. They make sure the calibration area remains undisturbed and indicate the non-scannable area at the edge.

Yes normally that is correct.
Wide area transparency places the focus on the glass plane.

Normal transparency is being used with film holders.
Here the focus is placed above the glass plane where the film in the holder would be located.


Kind regards,
Arne

What about if you use the Epson Fluid Mount Holder ?

Wide Transparency option or Normal ?

Dear user,

That depends on the holder. You will have to ask the manufacturer which mode to use.
If the material is placed directly on the glass of the scanner it would be the full area mode.

Kind regards,
Arne

I used the scan area guide, and laid a full PrintFile sheet of negatives directly on the glass. All of the negatives fit within the scan area. However, the scan included only the narrower 5.5" central area of the glass. I had selected "maximize active frame," but the frame also seemed to be narrow.

One more issue: if I reduce the frame to select a single negative, the color is fine. But when I scan the entire area, which includes a lot of clear plastic, the color does not render properly.

Dear user,

Did you switch from normal transparency to full area transparency?
The normal transparency mode only covers the central area. This mode also has a higher resolution and only using it you have access to the scanner's infrared correction.

Also are you scanning negatives?
Negafix auto adjusts to the histogram and would change.

Normally you should use individual scan frames for each image. A full scan frame wil never show best results because each image has it's own histogram, highlights and shadows.

Kind regards,
Arne
