LaserSoft Imaging

Hi,

i enabled "automatic when ADF" in the options and as a result i get scans with a terrible shade of blue when doing batch scans. Does anybody have the same problem?

Doing a single scan is absolutely fine and when i disable automatic, the scan is fine as well, but without any automatic adaptation. What's wrong here?

Any help is appreciated ....

Dear Willi,

What kind of material are you scanning? (positives, negatives)

Make sure only the image information is inside the scanframe.
If for example unexposed material is inside the scanframe that will disturb the image automatic.

If you are scanning Kodachrome images you will have to use SilverFast's special Kodachrome mode which will remove the blue color cast.

kind regards,

Hi,

thanks for that hint.

There is indeed unexposed material inside the scanframe. It is a very small area but this seems to have a big impact. The reason for the unexposed material is the "Automatic Frame Detection when ADF" feature which i enabled recently. If the frame is not detected precisely (which is actually the case very often for my material) a small black frame remains and the image turns to blue.

I disabled frame detection and selected the frame manually, now the automatic seems to work fine.

To summarize, for me it looks like i have to choose between frame detection and automatic. Since the frame detection anyway is far from perfect i opt for the automatic and choose the frame manually, that's fine for me.

Regards,

Willi

glad I could help.

For all of you out there that are wondering what all the options are doing, here is another hint.

Today i recognized that even with automatic when ADF disabled, there seem to be at least a bit of automatic regarding the illimination. I had a partial frame that was not detected by the frame finder. As a result i got a very bright scan, basically unusable, while halve of the picture was black. The black part forced the rest of the image to be very bright, which makes somhow sense, although it's maybe not a clever concept.

Actually what i would like to see is a one page description of what all these options are really doing instead of the 500 page manual. Of course, i know that's the hardest thing to do.

Regards,

Willi

This has nothing to do with the concept.
Unfortunately Computers are utterly stupid and can not "see" the image.
All that can be perceived are color shades and brightness values.
The Computer unfortunately has no way to differ between unexposed material and the Black Box you took a photo off.
So we have to implement certain standard sizes for the frames which the software expects.
Unusual image size or hard contrast can confuse the program.

That is something I would like to see too. Unfortunately our manual has 500 pages for a reason.
