filmscanners: Printdpi
The dpi thread leads me to ask what the best dpi for printing on an Epson printer (Stylus 600 for example) would be. My habit is to correct an image at the scanned resolution then move it to a default blank page for printing, using PhotoShop's free transformation for sizing. I save the 'print' version as well as the full resolution file. The prints look good. I normally use a blank page set for 8.5 x11 inches and 110 dpi. I'm wondering if I'd see better results at a higher dpi or faster results at a lower dpi. Lower dpi would result in a smaller file for storage too. There must be an ideal maximum resolution beyond which the image doesn't print better and a minimum resolution below which it is noticeably degraded. Comments? Rich

Well, yes, it is if it matters to you that the window should bear much relation to what eventually emerges in PS. There's evidently scope for handling things better there, and AFAIK VS makes no attempt at accurate, ICM display. Personally this doesn't matter one bit to me, as I use VS only to acquire a 16bit scan I can deal with in PS - but if you want corrected, 8 bit scans, yes, it's a problem. I think that we have to bear in mind where it started from, as a standalone scanning prog for the Photosmart only, pre ICM. There's a good case for a rewrite as a PS plugin, and another good case for proper ICM implementation, but that would probably lock out a majority of users who cannot afford the level of expense involved in this degree of obsessive behaviour. This might be a plea for a VS Pro version, if the market is really there. But it may well not be. I think if you add up the costs of mid-high prosumer scanning and dig imaging, it is truly scary. I expect most people who have and use PS have thrown $3-10,000 at their entire system incl. scanner, s/w, computer, printer. Then there's consumables and endless upgrades. I doubt many people get away with spending less than $2-3000/year, one way and another - and that's on top of cameras, F&P, etc. Even if you do this for a living, clients don't want to pay any extra and there's the added problem of ignorance messing up results, which makes them even more reluctant. I have mailed Ed and asked that he consider returning as I think there's some useful VS-related stuff happening here now. And I intend stamping my feet a bit harder WRT OT discussions.

Well, it depends on really what your needs are. If your output size is limited, then perhaps you can scan at a lower DPI and you will not see a difference in output. I believe you should always acan at the scanner optical resolution, as this will give you the best image your scanner can give you. I do not re-sample in PS, unless the output resolution falls below 180DPI or so...I uncheck the resample box, and just re-size and let the DPI fall where it may. It has been shown time and time again that there is no magic DPI. Now, your comment on file sizes is completely valid, and that is something I would suggest you experiment with to see what gives you the best results with that compromise, since making a scan at other than the scanner optical resolution will degrade the image. You will always get image degradation scanning at other than the optical DPI of the scanner. In small enough printouts, you will not see this degradation though, so if your requirements are such, that may work fine for you.
Re: filmscanners: Printdpi
The general consensus is printing in the range of 240-360dpi, and it will depend on the paper - for a good explanation of why see http://www.scantips.com/ The best thing to do is to experiment on *your* printer and find the optimal dpi for each type of paper you generally use. I did that for my HP PhotoSmart just the other day on HP glossy, and found that 240dpi appeared the best.

That's more comforting. For taking a raw scan, from any scanner, and into the variety of color spaces Vuescan offers, I assume Ed is assuming (1) a specific scanner may have the potential for delivering a wide gamut of color ... (2) a transform from that gamut to any internal color space can squash that gamut, and you'll never get it back. That being said, and altho I trust Ed, I know little about PCD RGB, and there seems to be little available regarding comparisons with the common working spaces (if comparisons can be made ... some of what I've found would imply apples and oranges). I will assume, until I realize otherwise, VS's internal space is sufficient for 1 & 2. shAf :o)
Re: filmscanners: Color saturation with Vuescan
Jim, I noticed I get "better looking" results scanning my Kodak Supra 400 with Generic Neg setting. Info posted on another thread indicates that Vuescan attempts to make all neg films "accurate" to a Kodak target, which seems to me would make all different types of neg film look alike. So, you might want to experiment using different Neg settings or generic. Also note color balance notes on Neutral vs. White balance etc. I guess it depends on the subject matter, ie skin tones or scenic. Jon __ Do You Yahoo!? Get email at your own domain with Yahoo!

Re: filmscanners: Nikon Coolscan 4000ED Review
Here are some conclusions regarding Nikon ED 4000. and 3 weeks try out. Sharpness, resolution: There is a problem with the film holders and flatness of the film. No film are exactly flat, and ED 4000 overall sharpness are not good because of curved film.. If the auto focus or manual focus are selected in the middle of the picture there is a excellent sharpness there but not out in the corner. With a test slide in a glass frame the sharpness is excellent all over the picture. It looks like the scanner lens are to open in aperture and lacking depth of field. ( There is the same problem with LS2000 sharpness and film holders.) What is the benefit of 4000 ppi scanner when the scanner not are giving a100% sharp picture? ( test your own film scanner by mowing the selected focus area from the middle and out 2/3 against the side or corner of the film) Scan and compare the sharpness in the middle and corner of the 2 pictures. 2. Regarding colors: Neutral in colors and free from noise. The software NikonScan 3.0 are not optimized yet. Slow in scanning, slow in transferring data to the disk, and do not work well with Photoshop 6.0 as a plugin. ( MAC) All the new features in NikoScan 3.0 as ROC. GEM. are working well but are also very slow. 3 Nikon ED4000 and NikonScan 3.0 will be a very good scanner combination when everything is optimized and the problem with curved film in the film holders and depht of field are solved.

filmscanners: TOtally OT: re copyrights
< Since this post is mostly "FYI" coupled with a short "editorial," feel free to delete at any time. ;-) > A news item of passing interest appears in March 2001 "Art in America" (last page). It seems that pop artist Barbara Kruger is being sued for copyright infringement by German photographer Thomas Hoepker, and (in a seperate suit), for invasion of privacy by Hoepker's model, Charolette Dabney, in US District Court, New York City. For those not familiar with Kruger's paintings, she often takes clips from 1950-60s magazines and blows them up directly, half-tone dots and all, to 3'x6' proportions ala Warhol/Lichtenstein, adding clever political comments of her own (usually of a feminist persuasion). Her work is interesting, well-done, amusing and thought-provoking, although probably more so as "political commentary" than as "art" with capital letters. Kruger's defense lawyers are arguing a "lapsed copyright" rather than the still-hazy "fair use" doctrine, so the case will have little if any implications on the latter issue. Seems that the copyright had run when Kruger picked up the clip, and was then arguably in the public domain, but the copyright was renewed before she finished and exhibited her painting in 1990; so almost any decision by the courts could result in further muddying of the waters, and "bad law" in general. The defense has, naturally, moved for dismissal on grounds the case has no merit. While I know that many members of Filmscanners are photographers and probably take a dim view of someone making paintings of their published pictures, it's my thought that only an idiot or a lawyer could try to make the case that a painting, done in oil, enlarged to the point of caricature and further enhanced by the artist, would constitute a "reproduction" in any commonly-understood meaning of the word. In fact, if I were Herr Hoepker (which I am not, BTW), I'd be secretly pleased that a painting based on my photo appeared in a New York gallery, and would be suing for Photo Credit and a small piece of the action, not copyright infringement! A small matter, to be sure, but a nice ego trip. :-) Anyway, that's my take on it. If anyone wants to comment, it would be best to take it off-list (not you, Laurie--we've already covered that ground! ;-) ). Best regards--LR --- FREE!

Re: filmscanners: Color saturation with Vuescan
Jon - Thanks It's one more thing I'll try... This stuff has about *a million* degrees of freedom, and in the end, I'm still working with something that's subjective. I'm afraid I may have been a bit too lazy so far. It's not going to work though - the canned solution isn't going to satisfy me. Are you happy shooting Supra? I've been using some Royal Gold, mostly 100 speed and I like it. I heard the two films were for all intents and purposes the same film, but I have no way to prove it. The skin tones from the automated prints I've gotten back from the RG weren't too good, but the ones I scanned myself are much better. I've been told by everyone that if I'm shooting people and looking for good skin tones tones I should be shooting Portra, but I really don't want to fool with the refrigeration issue, and I like how sharp the RG is. -- Jim >Jim, I noticed I get "better looking" results scanning my Kodak Supra >400 with Generic Neg setting.

RE: filmscanners: Printdpi
Austin's pretty much right, here, but I haven't seen much of the degradation he talks about in re-sampling, although I know it *has* to exist, given the nature of the beast. I would add that you should choose an optimum file-size based both on the ultimate end use and the finished size of the output. For example, I found that a 900-pixel maxdim file makes a good 4x6" printout @ 250dpi, and a decent (though improvable) 8x10" printout. By JPEGing, I can get files down to 100KB or less with relative ease. If your needs were more critical (say for magazine repros or later retouching), a higher-res TIF or such would be better. You'd be surprised how little space they actually take up on a 650MB CD disc, and discs don't cost that much, even if you insist on good ones (and you should). For resizing/resampling, Micrografx Picture Publisher 8 is an excellent program, IMO, better and more controlable than Photoshop, particularly for JPEGs. If you have size constraints, that's the one to use. OTOH, I might have read your question completely wrong. :-) Best regards--LRA == > The dpi thread leads me to ask what the best dpi for printing on an Epson > printer (Stylus 600 for example) would be. > > My habit is to correct an image at the scanned resolution then > move it to a > default blank page for printing, using PhotoShop's free transformation for > sizing.

Well, it depends on really what your needs are. If your output size is limited, then perhaps you can scan at a lower DPI and you will not see a difference in output. I believe you should always acan at the scanner optical resolution, as this will give you the best image your scanner can give you. I do not re-sample in PS, unless the output resolution falls below 180DPI or so...I uncheck the resample box, and just re-size and let the DPI fall where it may. It has been shown time and time again that there is no magic DPI. Now, your comment on file sizes is completely valid, and that is something I would suggest you experiment with to see what gives you the best results with that compromise, since making a scan at other than the scanner optical resolution will degrade the image. You will always get image degradation scanning at other than the optical DPI of the scanner. In small enough printouts, you will not see this degradation though, so if your requirements are such, that may work fine for you. --- FREE!

RE: filmscanners: Vuescan: "device RGB"
There is a lot that doesn't add up - - regarding PCD "space", and VS using PhotoCD "space". 1. You will note that you cannot do a profile conversion (profile to profile) in Photoshop to a PhotoCD (space) profile, of which I have about 8 of them in my ColorSync folder. 2. PhotoCD format - - and their ICC profiles ARE proprietary, and any use thereof would require a license. 3. If you examine each PhotoCD ICC profile, you will see a number of CLUT listing, and the sources are labeled "secret". That word. Each 16 bit profile has about 8 listings, all "secret" - - or proprietary. This is NOT the case if you examine Kodak's ProPhotoRGB space - for example. 4. You can open a PhotoCD - or a PictureCD using Kodak's embedded profiles, or can use one of the other Kodak CD profiles in your ICC profile bank, but you cannot save to PhotoCD, meaning you cannot embed (or format) Kodak's space. 5. If VS uses PhotoCD, what is he (Ed) using for tables, if the CLUTS are proprietary? And anyway, what good does it do in this case? I really wonder if this is fact that he is "assuming a space", and he thinks that space looks like a PhotoCD space. In an (off-list) correspondence with me Ed championed sRGB The sRGB profile consists of about 16 data points. That's it. A synthetic space meant for video and graphics on the web. 6. The scanner has its own RGB color response, usually evidenced by its profile. The profile merely maps the scanner's RGB data in a way consistent with the scanner capabilities, and therefore does not try to "remap" into a space either smaller or larger, or distorted, from the scanner response. Therefore what you get in Photoshop is "undistorted" RGB values, as delivered by the scanner. Most modern scanners have RGB responses far in excess of the media they scan, including E6, or Ektachrome, the media generally acknowledged to have the widest color gamut. In fact, the Nikon LS1000 has a gamut,or color response that well exceeds Ekta Space; the Imacon is way, way out there. Anyway, the scanner profile neither adds or subtracts from its intrinsic gamut. 7. If a profile is not used by VS, you have what is called "raw data", meaning as is, and not mapped. That is, if Ed isn't "remapping" in the background that you don't know about. And, even if the scanner profile is applied, that RGB will not budge from the untagged values. This is because the profile merely maps out what the scanner is doing in the first place. 8. All Kodak PhotoCD profiles exhibit very unusual gamut profiles, in either L.a.b., Yxy, or XYZ space. The are all complex. The only thing you can say is that they universally fit within Kodak ProPhotoRGB space. I don't know why Ed would even consider these spaces - - unless for PR reasons. 9. If VS is using some sort of "space" which alters the RGB values, and then doesn't "tag" the resulting image - you never know how much distortion has been introduced from "real" values. The image comes to you as untagged. If you apply a profile in VS, then the image should come to you as "Tagged", and you should see that (ICC profile) in Photoshop. Without this requirement, or data trail, you are in never never land regarding the fidelity of the original image. You might be bridging into touchy, unsafe waters by forcing out clarity on this issue - - Ed has a useful product to many on this list. And a good product to many.

I think there may be an issue here with what is "apparent grain" and what is "real grain" and what is "grain aliasing". In any case, I have yet to find a neg film which *doesn't* show unacceptable amounts of "grain" in things like blue sky, while pretty much *every* slide film gives reasonable results. A frame from Velvia last night made an absolutely stunning print on Heavyweight Matte. Changed my mind about photo prints on matte paper!

After looking into it only a little bit, I came away believing PCD RGB is sufficiently large and well defined to be used as an intermediate space. Vuescan does tag the images it exports in a variety of working spaces (including ProPhoto and Ektaspace), the only offering it doesn't tag is "device RGB" ... and it should be easy to see if it is anything remotely resembling sRGB. I'm quite curious ... I would ask VS for an sRGB image, and Ektaspace image, and the "device RGB" image.

filmscanners: OT: Photoshop LE
This is a "rant," so delete now if you've heard it before. ;-) I've just reverted to PS-5.0-LE--partly because a bigger PS was giving me problems, and partly to see "What are the Peasants, Doing, Tonight?" (bad joke, I admit--it needs the music). :-) Someone, a few months ago said PS-LE was a P.I.T.A.--oh, wait, that was me! But that was only after I'd just come off more friendly graphic programs on another machine which I've promised never to mention again. Well guess what: it still is! I doubt very seriously if anybody from Adobe is monitoring this channel. That's not like them, unfortunately (as opposed to *some* who regularly do, and you know who you are, and thank you). I also guess that if I could regularly sell upgrades and programs for $500 to $700 a pop after practically giving away "clipped" versions, I would surely do that, too. I might be a rotten businessman, but I'm not *that* stupid! ;-) OTOH, there's the little matter of Volume vs. Profits. It's like the kid who was imploring people to buy his pencils: "Hey, mister, would you buy a pencil to help put me through college? They're only $20,000!" "That seems a little expensive for a pencil," sez the well-dressed man. "Yeah," sez the kid, "but I only have to sell ONE!" It's an old joke, so I s'pose the price of the pencils has gone up to $60,000 ($150,000 if the kid wants to go to Harvard), but I guess I've made my point and I'll shutup now.

Re: filmscanners: Printdpi & A3 from 2720
Having just experimented with print resolutions using a very sharp Kodachrome 25 with lots of fine detail, I would agree with Bob's figures. I found that I could push the print resolution down to 140 dpi before I began to detect a noticeable difference in the prints when viewed at about 30cm (12"). (That indicates a good 25" x 17" print! is quite possible from a 2720 dpi scanner :), but by crikey your original needs to be spot on!) If you want the images to stand closer inspection, then 200 dpi is usually enough. There is very little difference (for naked eye viewing) above this, but it *does* depend on the subject, and I guess, your eyesight! Try it yourself.. And to answer the other enquiry - print times are dependent on your *printer* resolution setting, eg a 1440 dpi printout will take much longer than a 720 dpi one. Changing the image resolution will not help here. I suggest you stick to the highest printer resolution for the paper in use - at lower figures you get much worse dithering effects, esp. on a 4-colour inkjet printer.. Mark T.

Re: filmscanners: PhotoCD format
Graphics Workshop Professional can write the Kodak PhotoCD format, as I previously posted. From the FAQ page on the web site http://www.mindworkshop.com/alchemy/gwsproqa.html Q: Graphic Workshop Professional can write PCD files. Does this mean it can create complete Kodak PhotoCDs? A: Sadly, no. While Kodak has licensed us the technology to create PCD files a useful format for high quality imaging they have thus far refused to disclose the details of the other bits required to create a complete Kodak PhotoCD which would be readable by Kodak's set-top players. They seem to want to keep this facility for their own authoring packages. Graphic Workshop Professional can create multiple-resolution PCD files which are effectively identical to those created for a commercial PhotoCD. If you write these to a CD-ROM using the directory structure of a Photo-CD as discussed in the Reference document for Graphic Workshop you'll have a pseudo-PhotoCD readable by most PC-based applications, such as Graphic Workshop Professional itself. We're still working on the rest of the PhotoCD standard, but at the moment, this is as good as it gets. you wrote: >There are a whole host of imaging programs which can handle or open >PhotoCD format, including Photoshop.

I think what you may have here derives in part from the sky and other nominally bright parts of images on negatives being the darkest -- most dense -- in the film.

The "Transforms" you can download from Kodak - ASFICT are profiles, used to open files formatted in PhotoCD format. For opening files only. But you cannot open an image which is tagged in ColorMatchRGB, or AdobeRGB (say - scanned with VS and selecting one of these spaces), and then convert the *embedded* profile to PhotoCD profile, and then save to PhotoCD format. Even PictureCD. Such that when you open the file again, the profile (as denoted in Photoshop window - at bottom) will say "pcdcnycc"," pcdekycc", "pcd4050e", ", pcd4050k", or about 4 others that start with "pcd-". These are the Kodak PhotoCD profiles that are invoked when you open a PhotoCD file on a disk provided by a licensed service provider. These files, by definition of the PhotoCD format, come in at least six resolutions, depending on whether or not the file is "Pro", "Master", "Picture" - - . But at no time does the format permit only one saved file - as was implied by another poster. And, you can't even do this unless you are licensed, and are provided authoring software included in the license from Kodak. As mentioned before, the CLUT definitions are proprietary. And, you can't open a file into "photoCD space", You cannot load any of the profiles mentioned above as a working "space". If Ed is "doing this" - somehow - he is not doing this without Kodak's permission, unless he is licensed and has obtained proprietary authoring software. But even then, Kodak would take a dim view of anybody mucking around with their technology, that they invested so heavily into. They would have to insist that all licensees conform to standards agreed upon in the licence contract. > >I recall a long time back he said he was deriving some part of his >film type correction curves or matrix data from film type data from >Kodak for PhotoCDs. > >>9.

Re: filmscanners: File format
What would be the point of storing and reopening and saving the same image in a compressed format repeatedly. Each time there would be some generational loss. Store in an uncompressed native format to your graphics program. If you open a jpeg in Photoshop it automatically takes on the characteristics of a PSD. That's why you should save it as a PSD prior to working on it. Then use Photoshop's "Save for the Web" to create your compressed jpeg.

They are all different: pcd4050e.pf for E6 pcd4050k.pf for K-14 pcdcnycc.pf for color negative pcdekycc.pf for universal E6 pcdkoycc.pf for universal K-14 I can't tell you which one is used where. I have seen both the "pcd4050e and k" come up. All are Kodak device profiles, and have the ".pf" extension. And, all of them contain text detailing their *Copyright* information.

Just to paraphrase slightly, the best option is to keep a master copy of the image in a lossless format, and only convert a copy of the image to jpeg at the point when it has been edited to the final requirements. I use LZW compressed TIFF because it is transportable between different editing programs. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

I believe that for some reason there is more CCD noise in the blue channel than other channels. It may be that the effect of Nikon's collimated light is more pronounced in the blue channel than elsewhere - certainly shorter wavelengths might show different focus than longer wavelengths. However, the negative has the blue channel inverted doesn't it? :) I'm not hugely concerned about what the source of the effect may be - the fact is that on my LS30, all slide films scan far better in terms of apparent grain than the neg films I've tried. AFAICS slide grain is far more homogenous than neg film - which I presume is also why negs have much more latitude than slides. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

If you open and close ( or resave) the compressed file without changing the compression from one quality level to another in the case of .jog or without resampling the image prior to closing or resaving the file, there will be no more degradation than opening and closing or resaving a raw uncompressed file.

This is the main reason I am considering selling my Sprintscan 4000 and buying a Nikon 4000ED. The ability to drop a 36 exposure roll of 35mm film in and walk away.

Re: filmscanners: Vuescan: "device RGB"
Richard writes ... > Yes it is large. It will encompass Ekta Space (almost), which is the > definition of E6 Ektachrome media, and thus E6 gamut. I'm posting th results of my little test regarding the capacity of Vuescan's gamut, "device RGB" (... whatever it is ...) First ... some prelims ... I scanned an image into sRGB space 1st just for getting the colors approximately correct on my gamma=2.2 monitor ... and then loaded it into Photoshop 6. Next ... I scanned another image, without changing anything, into a wide gamut space, ProphotoRGB (gamma=1.8) ... and loaded it into Photoshop. Both of these "appear" identical, so there is nothing wrong with my monitor compensation. Second ... I scan having chosen "device RGB" which doesn't embed any profile, but is supposed to be Vuescan's color space. I can choose to "assign" any profile to it, and the profile which makes it appear like the others will give us an idea of "Vuescan RGB" color space. If I assign a profile and it appears over-saturated, then VS RGB has a smaller gamut than what I assigned, and vice versa if it appears under-saturated. The result is VS RGB is somewhere inbetween ProPhotoRGB and sRGB, and most like EktaspaceRGB. Unfortunately, VS RGB is a smaller gamut than what Nikon believes belongs to the LS-2000 ... if I assign "Nikon_wide" the over-saturation is obvious. Fortunately, and as Richard stated before (at least with respect to Nikons), the scanner's gamut is designed to exceed that of the media ... so Ektaspace is an easily accepted compromise. Ektaspace is also respected for its editabilty, and its wide gamut is very suitable for highbit editing. Its gamut is also sufficiently wide for archiving. The downside of VS RGB, besides being smaller than some scanners' device spaces, is that it is significantly smaller than "Adobe wide gamut" and ProPhotoRGB. That is, you get nothing by choosing these two color space options ... unless you like a lot of headroom for serious Photoshop adjustments ... but the "beyond gamut" results of such adjustments cannot be seen in monitor space, so what's the use(?) The good news is VS RGB is sufficiently large. No one should complain for lack of gamut ... no matter what the application post scan. It is also sufficiently large for some serious and creative highbit adjustments. On the other hand, if Ed wanted to extend Vuescan's market into professional work, he might want to consider a different internal color space for Vuescan 'Pro'. my US$0.02
RE: filmscanners: File format
This is what I thought, too, but before venturing to say so, I actually performed an experiment, repeatedly saving the JPG file at the same compression factor. It got smaller by about 2% each time I saved it. It is probably honing in on some optimized compression at that level of quality. Visual inspection couldn't detect any degradation.

Re: filmscanners: File format
Just a note on LZW compressed image portability - I have run into one instance where an LZW compressed image was not portable - when exporting a 48-bit compressed TIFF from Vuescan to Corel PhotoPaint 9 it opens but the image is unrecognizable. If exported uncompressed there is no problem, and once in PhotoPaint it can be compressed using LZW. This appears to be one exception.

The raw scan is in an unspecified device space, scanner RGB. Ed's transform, applied during the production of the Crop file, munges that against his characterisation and the result is a scan with altered data values within Vuescan's working space (which I previously said I thought was maybe sRGB, but as has been pointed out it ain't, it's Kodak's PCD space - too many facts, too little brain:). This isn't classical ICC-type colour management (=don't change the data, just append a tag which provides a map for interpretation of device colour). Vuescan does change the data, so you can't go backwards - the original scanner RGB has gone. However you do now have a scan in a known colour space (PCD) which can be mapped and tagged to any other colour space, sRGB, AdobeRGB etc. It's perfectly legitimate, nothing is broken - but you should regard VS internal working space as the device space here. So you don't want to go applying other profiles for the scanner, from other sources, at that stage, as the image is no longer in scanner RGB. >(Tony > ... correct me if I'm wrong ... I think this is what your > 'step-by-step' Vuescan method implied.

Quite. The whole point of VS is to avoid all that - either because VS does it better (=design aim) or because the OE scanner software doesn't use ICC at all. > To impose (assign) one on top of the other makes me uncomfortable ... It's an either/or proposition; you should never be applying scanner profiles to the Crop file. If you want VS to produce legit, tagged files, corrected for the scanner's deficiencies (and film characterisations too), use the Crop file. If not, use the raw file, or other software, and DIY. > I certainly am more comfortable with the scanned image inheriting the > device space because nothing was done to it (... not implying the > 'raw' scan' because we are still trying to use Vuescan's cropping > tools ...) ...) But VS doesn't implement CM 'properly' - if it did, Ed would have to bundle his scanner characterisations as ICC profiles and he declines to do that as everybody would pinch them and not buy VS. For the same reason, you'll find vanishingly-few PD profiles on the web, and people like Jon Cone making a living by selling them (for Epson piezos). The downside is that this approach locks VS out of using any device profiles you might make yourself for your personal scanner/film combination, to produce the Crop file. However VS still gives you the wherewithawl to create and save a raw scan which you can then work with in PS, using device profiles or anything you like.
