Sharpening versus Not In Focus

[BRIANPHOTO2]

How can you tell whether a scan is not sharp because (1) you did not apply enough sharpening in AI or (2) the film was not physically focused (i.e., the film holder was not the correct height on the scanner)?

Hi Brian,

How can you tell whether a scan is not sharp because (1) you did not apply enough sharpening in AI or (2) the film was not physically focused (i.e., the film holder was not the correct height on the scanner)?

You can turn the auto-sharpen filter and check pure optical outcome.
If you are using the filter" Sharpen (USM)" you will have a preview window where you can see the strength of effect applied.

Hi i have a problem, i checked the filter spot and i used that in none.
I scanned an slide and i compared that with another V750 with same settings and mine
seems out of focus. I think is the height, how can i know the correct height of the holder? or any solutions?

thank you.

dear dessmond,

The V750 has two fixed focus planes.
These are activated in the general tab.
The normal transparency mode is for the use of the film holders.
The transparency (full area) for use with filmmaterial placed directly on the glass plate.

Neither can be directly influenced.
The only way is to use special film holders with adjustable hight which some companies offer.
These can be used to bring the images to the correct focus hight.


kind regards,
Arne Ketelhohn.

Thank you.

I have one more problem.
The lamp to scan slides is working strange or the upside of the scanner, it was working really good and then
it works really slow and it makes a strange sound, it seems like something is stuck.
I can't scan anymore, at first it scanned with some color lines, and then it was dark.
What could be the problem?
Im working in batch mode.
Thank you some much

dear dessmond,

That is something you will have to contact Epson about.

kind regards,

While reading various helpful dialog, I did not see reference to the 'height adjustments' on the Epson V700 film holders. The following URL will provide this and much more information re: this scanner: http://www.imaging-resource.com/SCAN/V700/V700.HTM. The following paragraph from that source is quoted:

"When installed with the arrow facing the plus, the holder rides 0.14 inch (3.5mm) off the document table. With the arrow facing the circle (as shipped), the holder sits 0.12 inch (3.0mm) from the table. With no height adjusters installed, the gap is 0.1 inch (2.5mm). They are easier to push out than pull out and when you do, you'll see the small notches on either leg are not the same height. So when you turn them around, the notches click into the holder at a different depth."

There are some very clear pictures on the referenced page (tried to paste in here; failed)

I turned my 'adjuster arrows' to "plus" and focus improved over the factory suplied adjustment of " 0 ". It is only a 0.5mm difference. I ave experimented with 0.2 mm card stock as shims and this makes perceptible changes, but I am staying with the "plus" setting for now. Such shims could be permanently attached and used on spare height adjuster provided.

I am curious on any other comments and experiences with this approach.

Earlier post suggests that you can select foucus plane in the general tab. This option is not available in Silverfast 8. Am I missing something?

Thanks

Can not someone at LSI answer this?

Thanks

You can change that in the same selection it has been previously.
The transparency/reflective selection is above the settings dialogs.
