Silverfast 9 bursts forth - UPDATED

just when they least expect it…

in Silverfast , Friday, December 18, 2020

A totally unexpected email popped up in my inbox yesterday, announcing the release of Silverfast 9. It’s a weird time of year to announce a new product, but Lasersoft are a weird company (I used to think of them as eccentric, which has a certain charm, but now they’re just weird, as in irritating).

I still like Silverfast. Actually, it’s chugging away now on my Mac, but only as a input provider to Negative Lab Pro. But this update… well, let’s see what’s new:

Banner silverfast9 newsletter en

So, the headline feature is a new E-Book, written by Chief Mad Scientist, Wing Commander Karl-Heinz Zahorsky. Ok. I wonder what Mark Segal thinks about that?

Then we have Innovative Design. Well, from the screenshots this appears to be a touch more lipstick, only this time also available in fashionable black. I regret my cynicism, but I very much doubt that any of the outstanding usability issues have been fixed. The actual layout looks 100% identical to Silverfast 8, with - and here we have to recognise a serious accomplishment - even uglier icons.

Next up, My SilverFast Portal.  This is apparently a web page where I can see a list of licenses I own. Awesome.

And last but very much not least, SAC - Single Archive Command. Yes, we get the obsessive Air Force reference. What this does is anybody’s guess, but it claims to be a “One-click-archiving solution”.  Basically it seems to be rearranging some existing deckchairs (auto frame finding, Job Manager, VLT), and is of use only for flatbed scanners. Also, the blurb adds, without evidence, “you too can enjoy the advantages of our scan booster with the Single Archive Command” and “75% faster with SAC”.  I have no idea why scanning speed itself should be faster with SAC, or why it should be only available through SAC. Sounds a lot like bullshit to me.

So, that’s it. Apart from some other unspecified “improvements”.

And how much does it cost? Well, as ever, Lasersift is very coy about this, making you jump through all sorts of hoops to get a price.  Here’s what I found, eventually:


So, the Archive Suite, which includes Ai Studio AND HDR Studio, costs less than half the upgrade price of Ai Studio alone. Ok. Whatever.  Note the “new” prices though - not sure what they’re smoking up in there in Kiel, but I want some too.  Of course, this only allows my to run SF9 on my Plustek scanner, not on my Canon scanner.  I expect I’d have to pay the same price again to have both on SF9. And I would be very unsurprised to find that trying to run SF8 for Canon and SF9 for Plustek leads to System-Fehler-Alles-Kaput.

Anyway, I suppose I’ll buy it at some point, but based on experience the initial release is likely to be a stable as one-legged Bremerhaven dock worker after a night on the schnapps.

There is one interesting thing - apparently it supports the mythical Plustek Optic Film 120 Pro.

The website is of course a total train wreck, but you can try to check out Silverfast 9 here.

UPDATE, 21st December
Well, I did buy it. Part of the rationale was that LaserSoft have been quite generous with their upgrade policy with v8.  Certainly the first 18 months or so was just bug fixing, but some useful new features were introduced in later 8.x releases, particularly the Copy/Paste settings in Job Manager.

Well, what v9 brings to the table is actually a slight improved Job Manager dialog (all it is somewhat a case of 2 steps forwards, 1 step back), and, get this, they’ve actually REDUCED the Copy/Paste functionality.  Apart from that, there is nothing new I can find apart from a bit of a visual overhaul, which doesn’t amount to much.  The “new E-book” displayed prominently in the marketing email is not included in the release, but is yours for an extra €29.99.  This is a clear case of misadvertising in my opinion.  Then again, I doubt that the content amounts to much more than self-promotion.  I’ve had a good look, but I cannot find the “new NegaFix profiles” mentioned on the website.  One new “feature” is that v9 implements internet-managed spyware licensing. Yet another thing for LaserSoft to screw up, and they surely will.

So-called HDR-Raw files produced in Silverfast Ai v9 and processed/saved in HDR v9 open fine in HDR v8, so clearly nothing significant has changed at the level of file processing.  The much vaunted “One Click Archiving” is not enabled for my Plustek Optic Film 120, even though it can take a tray of up to 10 unmounted 35mm frames (or 5 mounted), so it could potentially be useful.

So what, substantially, do you get for your money?  Maybe stability with new OS releases? A nice warm feeling that you’ve given money to that nice Mr Zahorsky & friends?  I’m afraid that’s about it.
It is still, in my opinion, the best scanning software on the market, but from a company that’s even harder to like than Adobe. And that’s quite an accomplishment.


Silverfast open wishlist

do feel free to ignore me

in Silverfast , Thursday, September 20, 2018

Some time ago, I submitted a list of carefully thought out feature requests to the appropriate section in the Silverfast forum. This, being one of the most dysfunctional software product official fora I have ever seen, my post was not uncharacteristically ignored. I am used to Silverfast’s public facing support being as unbelievably incoherent as their software, and indeed direct customer support, is good, that I just accepted that my goodwill as a customer means zero to Silverfast / Lasersoft, and the time that I spent compiling the list equally so.

But anyway, in the hope that just possibly another route might work, I’ve finally decided to post a version here. After all, this is not a list of complaints, but rather observations from a heavy Silverfast user, and features I’d like to see implemented.

I have been using Silverfast constantly for over 15 years, and even if I have some criticisms, I am happy with it, and thankful that it exists to enable me to make faithfull scans of both negatives and slides. I’m a Silverfast fan - just, as the French say, “Qui aime bien châtie bien”.

Feature requests: Most of my suggestions pertain principally to Silverfast HDR, since I always use the seperate scan/process workflow, but some may also relate to Ai. So, here we go.


Dear Silverfast,

1. Zooming

Please provide a more intuitive zoom mechanism, following general industry practices, e.g. as in Photoshop, and allows a numeric input ? Also, please provide generic 1:1 / HQ buttons outside of the processing tools, for example in the menu bar, so that these can be activated without enabling a processing tool.

The current Zoom tool is not really a zoom tool at all, more a toggle between a zoom level set elsewhere, and full image view. Therefore, the Zoom tool is only activated if the preview is in 1:1 or HQ mode (only achievable if one of the relevant tools such as USM or iSRD has been activated first), or if command-drag has been used to focus on an arbitrary rectangle. Command-Drag allows an arbitrary zoom of any given area (although it seems rather unstable), but the numeric value is known only after the zoom. Also it does not work if 1:1 or HQ is set first. Afterwards, the zoom tool is active, but only 2 settings - “zoom in” =1:1, “zoom out” = “fit in view”. To get to, say, exactly 200% is more or less impossible. Being able to zoom into an image to evaluate (e.g) sharpness is a key part of the editing process, and until Silverfast HDR offers this, it will never offer a complete solution.

2. Frame cropping

I would recommend making the ability to rotate frames a bit more obvious. The purpose of the handles is not well revealed by the closed hand pointer; a rotate icon would be better. Also, a levelling tool would be nice to have, as would be the ability to constrain cropping to a set ratio, or the existing ratio by, e.g., Shift+drag (although then the shift+click shortcut for the colour sampler would have to change)

3. Startup / Utility screen

It really isn’t clear why needs to be shown at startup, in particular in SF HDR. There is no scanner choice required, so why put up this blocking modal dialog ? It should instead be possible to open the ultility screen from the Help Menu, similarly, if I remember correctly, to SF 6. The problem is the current mechanism prevents opening images directly in SF 8. Say, for example, I have my scans organised in an external DAM application, such as Photo Supreme, which allows me to maintain permanent catalogs. From there I can open, e.g., a TIFF in Photoshop in one click, but I cannot open an HDR-TIFF in SF HDR because of this blocking dialog.

Even better would be to be able send a series of images from the external application to the Job Manager. This is not a criticism of VLT. VLT is a good basic management tool and has its place in my workflow, but it cannot create catalogs, and it is not practical for managing 1000s of scans. As far as I know, Lasersoft is not competing in the DAM software market, so what reason could there be to
not play nice with these applications?
So, please could you consider changing how the service dialog is accessed ? It would massively improve usability within a full-system workflow (And maybe not only just in HDR, although in SF-scan it is less of an issue)

4. Multiple frame selection

Multiple frame selection for film scanners. This might sound strange, but here is a use case: to scan panoramic format 35mm frames on Plustek 120, I use the Plustek-recommended method of inserting the 35mm filmstrip holder but telling Silverfast that it is a 6x9 holder. Then I can preview and set a frame on the 24x66 area. However I can load two 24x66 strips in the 35mm holder, so it would be very useful if I could then set two frames in Silverfast, as I would be able to do on a flatbed scanner. Of course, I do know that you can “queue” scans in Silverfast (set the frame, start scan, set another frame, and click scan again, it will process the second when the first has finished), but that is a feature you discover by accident, and it gives no feedback whatsoever.

5. UI stuff

- remove the IT8 button from the vertical tool bar. Since it is more of a configuration task, and in particularly in Silverfast HDR is a very specialist tool indeed, it really doesn’t belong there and is far too easy to click by accident.

- a “percentage” option in the Image Dimensions / Output options would be extremely useful.

Allow the auto-frame tool to redefine an existing frame, rather than wipe out the already set filename.

Add a colour picker (similar to the midPiP tool) to the (excellent) global colour correction tool to enable increased selection accuracy.

A configurable high/low clipping indicator would be nice too. Just about every other application has this.

Specific to VLT

- Make VLT Thumbnails update based on HDR/HDRi saved settings - including rotation.

- Make it possible to start Job Manager when in VLT mode.

- Allow deletion of files from VLT browser

Finally: I’m not here to tell Lasersoft how to run their company. My only wish is that they survive and continue to support the current product portfolio. However, I would observe that they are dramatically missing an opportunity in not fully engaging with the #FilmsNotDead movement. For a start, modernising and opening up the Silverfast forum to become the reference place to visit for expert and user to user advice on film scanning would I believe generate significant benefits for Silverfast. This would also mean opening up user to user discussion of competing products, and to be tolerant of reasonable amounts of criticism, even when it is unfair. Appointing moderators from the community can help, so that Silverfast employees do have to engage directly. This is not a revolutionary idea: it’s 2018, but the Silverfast forum is stuck in a 1998 mindset. I cannot see how getting free feedback and input from paying, engaged customers, channeled through product management could have a downside.

(Postscript: I note that Silverfast is inviting visitors to see them at Photokina. I guess to speak to a rep they'll have to line up for a ticket, get the ticket approved by a booth moderator, wait for a reply, get a ticket to reply to the reply, and so forth. Should be fun.)

New Favourite Film

green is the colour

in Film , Friday, July 20, 2018

I think I have a new favourite film. I was tipped off about by Alex Burke, in his excellent eBook, Film in a Digital Age. It’s called Fuji Pro 160NS.

I was only very, very vaguely aware of this film. Actually, I don’t think I’ve ever used Fuji negative film before, ever. I’m strictly Kodak. I’ve just gone back to check what Alex Burke writes about Pro 160: “as with Portra, it has an incredible dynamic range but I felt it to be a tad more contrasty and colorful”, and “this film is all about the greens. Many people say that the Kodak negative films are more for red hues and the Fuji 160NS is about greens”. From my experience so far I completely agree with both statements. Kodak Ektar certainly likes reds - in fact it makes everything red. And indeed, my first impression was of a less washed out Portra, but without the shrill vibrance of Ektar.

The results look fantastic to me, straight out of the scanner. The two examples below were scanned in Silverfast using the Fuji Pro 160S 6x6 Negafix profile, otherwise totally un-retouched.

SRDx Photoshop plugin

A short review of Silverfast’s spinoff

SRDx is a Photoshop plug-in promising to be “new standard for
Dust and Scratch Removal”. It is fact derived from the SRDx feature included in the Silverfast scanning application produced by Lasersoft AG. As a plug-in SRDx is being marketed separately through its dedicated website.


Silverfast also offers iSRD for scanners which include infrared channel output. This provides an effective way to remove the majority of dust and scratches from scans (although the patching itself is not perfect). But for some film types, in particular black & white negatives and Kodachrome, this doesn’t work. SRDx uses some form of contrast detection coupled with a proprietary algorithm to detect dark or light defects. Back in The Old Days (i.e last century) there were a number of such Dust and Scratch removal plug-ins, in particular one from Polaroid. They didn’t work very well, and neither did (or does) Photoshops’s own filter, which is a very blunt tool. However, Photoshops current manual healing tools are very good, so what can SRDx offer ?

Well, in a word, automation. SRDx is actually fast, flexible and effective. I have a large hoard of Kodachrome slides, and every few years or so I try once again to revive some of them.  Many years ago I stored them very carelessly (I had no idea at the time) and they have been infected by fungus and are often very dusty. Sadly SRDx can’t do a lot about the fungus - although in some cases it has helped - but it can make short work of other imperfections.

Here’s an example. The first image is of a complete Kodachrome scan opened in the SRDx plug-in in Photoshop. It presents a simple, clear User Interface.

Srd full

SRDx automatically detects imperfections, and marks them (by default) in red. It has several tools for manual adjustment, including a brush for marking undetected defects, and iteratively strengthening the effect, an eraser for zapping false detection, a mask tool for adjusting area for consideration. The automatic detection can be fine-tuned using the detection intensity and tile size sliders. Settings can also be saved as presets.  So, it is simple, but quite comprehensive. The view can be switched between Original / Mark / Optimised. An example at 100% is shown below:

Srd correct

As mentioned, SRDx is also available within Silverfast & Silverfast HDR, but there I find it a lot less useful. Since Silverfast works with by default previews, for SRDx to work you first need to make an “HQ Preview”, which is Silverfast Marketingspeak for a full scan. You then have to wait while it applies all its processing, which for a medium format high resolution scan can take forever. In such a scenario SRDx is an exercise in frustration and essentially useless. It isn’t that much better in Silverfast HDR. On the other hand, in Photoshop, it is very fast. Finally the patching is also better in the plug-in version.

The masking took is useful but it would appear that despite the fact that you can name the mask (in Silverfast you have to), in fact you can only have one mask. Also, for some reason, in the Windows version masking is not included. This would be a major issuer are if I was a Windows user.

In conclusion then: 15 or 20 years ago this would have been a no-brainer. Lasersoft AG have taking SRDx out of its constraining environment in Silverfast and given it a new role. This enables a much faster workflow. If, like me, you have a lot of non-Infrared compatible film to scan and clean, SRDx is a considerable timesaver and recommended. At least the Mac version. At €49 it is reasonably priced, much more so than the initial €99 which was ambitious even by Lasersoft’s standards. For Windows, due to the mask issue, personally I would not recommend it. From time to time Lasersoft offer special pricing - I had an offer last year at €20 which I missed out on. At that price I’d say go for it, on both platforms.

SRDx doesn’t work miracles but it is pretty good - better than I expected in fact - and if you have a need for it, it is worth the price. Unfortunately for Lasersoft, I suspect the market is small, and getting smaller. But I wish them good luck with this initiative.


OpticFilm 120 vs. Flextight X5 - Round 2

the plot thickens

{categories limit="1"}in {category_name} {/categories}, Wednesday, August 30, 2017

Last week I published the first part of my Plutek OpticFilm 120 vs Hasselblad Flextight X5 scanner bake-off. The results from scanning XPan frames were surprisingly close, with the X5 subjectively winning by a whisker.

The key word in the above paragraph is “subjectively”. Because film scanning is nothing if not subjective. While preparing this second part, I once again fell down the rabbit hole of comparing output from different scanners, different software, different settings, reproducible bugs, irreproducible bugs, and indifferent customer support.  I learned, or-relearned, a couple of key points about scanning, which can be summed up by saying that magic features - like “multi-exposure” - generally don’t work. It’s better to keep to the basics.

That out of the way, this time around I’m going to look at two Medium Format scans, a Portra 400 negative taken with the Voigtländer Bessa III 667, and a Provia 100F positive taken with the Linhox 612.

First up, the Portra shot. This was taken in a secluded spot in Venice, far from the tourist gyres.  Note, you can click on any of these images to see them in larger size on Flickr.


Left: Plustek OpticFilm 120 (OF120), right Hasselblad Flextight X5 (X5)

In this case I decided to apply a simple grey balance using the same reference (the letter box in the background, on the right) in Silverfast HDR for the OF120, and in FlexColor for the X5. For the OF120 I used Silverfast’s Negafix Portra 400 profile, for the X5 I used FlexColor’s Portra 400NC. As you can see, they’re pretty close. Preferences are subjective. I could show you a similar frame from my Sigma DP0, and you would see that there are differences, but if I went down that path it would never end.

So, what about detail ? Well, I decided to zoom in on the notice in front of the staircase. Since the OF120 allows a scan a 5300dpi, and the X5 only at 3200dpi, the size at 1:1 is different.


1:1 zoom - left: Plustek OpticFilm 120 (OF120), right Hasselblad Flextight X5 (X5)

The extra resolution of the OF120 doesn’t really seem to add much, here. But it might be interesting to downsample to 3200dpi to get a better idea.


Matched resolution - left: Plustek OpticFilm 120 (OF120), right Hasselblad Flextight X5 (X5)

Well, that’s interesting, isn’t it ? As we saw in the last episode, the X5 is perhaps slightly less noisy, or possibly the diffuse light source is decreasing grain contrast, but in terms of resolution it’s pretty much a dead heat.  The OF120 scan is a little more contrasty, which may give the impression of more detail. On the other hand, it may really be delivering more detail.

So far so good, the Plustek has nothing to be ashamed about.  Let’s move on to the Provia frame. While colour negative film presents substantial challenges in colour representation, it is generally low contrast. Slide film , on the other hand, should present less problems for colour accuracy, but contrast is another matter altogether. Shadow areas can be extremely dense, and detail easily visible on a light table can be completely lost in a scan. Provia isn’t too bad in this respect, but Velvia is very tricky.  It’s just as well that I don’t much care for Velvia.

So, here’s our Provia frame:


Top: Plustek OpticFilm 120 (OF120), bottom: Hasselblad Flextight X5 (X5)

You can immediately see a colour difference. The X5 scan is direct from FlexColor with all settings zeroed, and sharpening off. The OF120 scan has had some magenta removed from the highlights and shadows, and contrast reduced slightly. The FlexColor scan is a remarkably accurate representation of the slide on the light table, to my eyes. The greens especially are more accurate. The OF120 scan seems to be lacking a certain amount of tonal separation in the higher midtones. Still, I’m not sure there’s $23’000’s worth of difference.

So what about detail? Slide film is generally sharper than negative film, so this also could be more challenging.  Note, however, I’m not really very familiar with the Linhof 612 yet, and I have some question if I was using an optimal aperture here.


Top: Plustek OpticFilm 120 (OF120), bottom: Hasselblad Flextight X5 (X5)

In the above illustration I have downsampled the Plustek scan to 3200dpi. Although contrast and micro-contrast might be playing a part here, I have to - just - give the prize to the X5. Looking at the tree branch, you can see a smidgeon more detail. But let’s face it, unless you make a print the size of a bus, it is totally insignificant.

Note though, if you allow FlexColor to do post-capture sharpening, the gap widens considerably. FlexColor appears to have very good sharpening algorithms, tuned to scan resolution and scan type.  Silverfast’s USM on “automatic” setting is also not so bad. But nowhere as good as the FlexColor / Flextight combination. Still, there are many options for sharpening.

However, there is one area where the X5 nails it. Just as we saw for the XPan slide scans, for shadow detail the X5 wins easily.  In the sample below, I haven’t even touched the shadow depth slider in FlexColor, which can widen the difference still further with significant downside.


Shadow detail - left: Hasselblad Flextight X5 (X5), right Plustek OpticFilm 120 (OF120)

So, from this point of view, it is difficult to avoid envious glances in the direction of the X5, or at least it’s X1 sibling, which is only astronomically priced rather than absurdly.

But wait.  There’s an elephant in the room, keeping very quiet over there in the corner. Well, a very small elephant.  Take a look at this:


Same slide scanned using the Canoscan 9000F

The above version was scanned on the Canoscan 9000F flatbed scanner using Silverfast Ai Studio, calibrated with the same IT8 slide as the OF120. This is straight from the scanner, with all Silverfast settings flat. The colour accuracy is quite noticeably better than the pre-adjusted OF120 version, and it appears to have more shadow depth.

This is a bit scary. So what about resolution ?


1:1 - top: Canoscan 9000F, middle OpticFilm 120, bottom: Flextight X5 (X5)

Well, the 9000F can’t quite keep up, but at less than 1/100th of the cost of the X5, I guess it does a reasonable job. I only really bought the 9000F some years ago because I needed a document scanner, and remarkably it came bundled with Silverfast HDR: this was easily the cheapest way to acquire that software. So really I haven’t paid that much attention to it. It just sits there and does what it’s told. I am vaguely aware that it has a reputation of being rather under-appreciated, especially compared to Epson flatbeds.  These days you can pick up a 9000F MkII, sadly without Silverfast, for just $200. The film holders are truly horrible, but otherwise, it’s pretty good.

So, what about the OF120 vs X5 ? Well, I think the OF120 delivers quite enough resolution. Colour accuracy is another matter. Of course, one could blame Silverfast, but I have used the latest versio of Vuescan as well and have found similar issues. And the same Silverfast delivers much better results with the Canoscan.  I have made a whole series of Portra 400 scans with various combinations, which I may present as addendum, but in that case getting good colour out of the OF120/Silverfast combination proved quite a challenge.

On balance I think the Of120 put up a pretty good fight against the Flextight X5, but at the same time it is not as superior to the 9000F as it should be.  For scanning 35mm film I’d still go with the higher resolution of the OF120, but for medium format, honestly I’d be tempted to recommend the cheap but excellent Canoscan, or perhaps the more expensive but theoretically superior Epson V850 (which I’m tempted to try). One advantage that a dedicated film scanner should have is delivering better shadow depth and tonal separation for slide film. I’m not convinced that the OpticFilm 120 achieves that.

As a final note, I should point out that I haven’t yet extended testing to black & white film. That brings a completely different set of issues, and may well result in very different conclusions.  I don’t generally have much to do with black & white, but since I have 5 rolls of Ferrania P50 to burn through, I may have something to say on this later.

Finally, if you have any questions, feel free to ask…
