LaserSoft Imaging

Hello, Can you tell me if it is possible to manually control the focus of a V700 with Silver Fast and which version of the software do I need? I currently have 6.6 SE. Also which lens does Silver fast control on the V700 I heard that it will not engage the sharper of the of the two lenses on board, is this true? Cheers

dear pgfitz,

It is not possible to manually control the focus of the scanner. It has a very shallow depth of field and only two focusing positions.

Absolutely not true, SilverFast uses both lenses. Under the "original" menu you will find the options "Transparency" and "Transparency full area", the former should be selected when using the film holders, the latter when scanning film material in direct contact with the glass surface. SilverFast SE has this two options.

Cheers

So does this mean that the focusing is determined by the full area or film holder area.

If so what happens if you want to scan 8x10 film wet mounted with the Epson wet mount film holder?
You would need the full scanning area to cover 8x10, but choosing that setting would set the focus to film holder
that is higher up.

Hi Fred,

Correct, full area focuses on the glass surface of the scanner, transparency (not full area) focuses a couple of mm above the scan surface to fit the distance of the film holder.

If you check your fluid mount you will see there is a guide indicating the limits of the scanning area. This guides clearly show the scanning area is smaller than the glass surface, if you place something beyond those limits, obviously it can not be scanned.

Also the fluid mount glass is narrower than 8x10, probably you will have to place those films directly to the scan surface.

Cheers

i remember someone talking about direct wet mount on the Epson glass with some special tape and wet mount fluid for larger films. just can't put my finger on the url just yet.

ok here's one

Gentlemen, where is this in Silverfast Ai Studio 8? I need to find it and I cannot see the menus you are discussing.

Dear customer,

are you talking about the transparency selection?
That is located in the upper left of the SilverFast 8 screen.

No. I was already choosing 'transparency' instead of 'wide transparency', I was trying to figure out if there was some other focus control in Silverfast that would explain why scans are so soft.

Since i posted this I have been doing comparisons with the free Epson Scan utility, and I think there must be a fault in your silverfast software. My logic is as follows:

I am scanning 35mm film using epsons film strip holder.

When i scan using epsonscan, the software knows it is film and alters focus to account for the film holder being raised slightly from the glass. I get a sharp scan everytime. So it would seem my scanner itself is fine, and the epson software knows how to use its fixed focal lengths so i get sharp scans.

With silverfast I am manually selecting 'transparency' which I am told is what I am supposed to do for this scanner, but the scan is soft every time. as focus is fixed, there is nothing I can alter there, and it does not matter what else I alter (USM, resolution), the free epsonscan utility beats your software for sharpness everytime.

This seems very wrong, and somewhat distressing being as I paid handsomely for the v8 upgrade for compatability with my OS (v6 will not run on my OS) only to find that the free software is much better!

I have to assume that silverfast 8 is not correctly accounting for the raise from the glass created by the film strip holder. Being as silverfast is supposed to support this scanner (indeed an older version v6 is supplied with it) I find this very disappointing. Clearly it did factor the raise from the glass as well as the epson utility back in silverfast 6 or epson would not have bundled it. What can be done to restore this functionality please?

Dear customer,

No, the EPSON V750 has a fixed focus.
It can not adjust the focus.
The scanner can only switch between it's two lens systems.

The second image was probably software sharpened.
The resolution is not high enough to say for sure but that heavy grain looks like it results from a too strong sharpening filter.

You can also use software sharpening in SilverFast through the USM tool.

Hallo,

at first, sorry for my bad english.

I have changed to SF8 and the Scans are not sharp since them. I scan positiv, direct from the glas of the scanner.
Idid not font the section for transparency. Where is it?

Regards Volker

Dear Volker,

The selection is in the upper left corner, next to the Positive/Kodachrome/Negative selection button.


Kind regards,
Arne Ketelhohn.

What settings do I use for frame finding with Epson v750 with wet mount?

For wet mounted images you should use the wide area transparency and there the general frame finding.
The holder based frame finding is only used with the standard film holders.

Kind regards,
Arne

Unfortunately I have to tell you that the result is pathetic. i am using this: https://epson.com/listing?q=%3Arelevanc ... _onRefresh

unfortunately the focus of the scanner itself can not be adjusted otherwise.

Have you checked if all other settings are correct? like high enough resolution, USM or any other tools that might adjust the image.


Kind regards,
Arne
