[filmscanners] Installing LS30 on XP
I've just set up my LS30 under Windows XP. Along the way I was looking at Maxwell Optics' FAQ about the topic (Maxwell are the Australian Distributors for Nikon). The link below contains a link to ASPI drivers for Adaptec SCSI cards which gives me a 404 file not found error. Does it work for anyone else? http://www.maxwell.com.au/support/faq/11448_ls2000xp_jw.html Other than this problem, the information provided on the site about installing the drivers with XP seems excellent to me.

[filmscanners] Re: VueScan file size
Thomas Maugham [EMAIL PROTECTED] wrote: I just scanned a negative and got the following information from VueScan: 5576 x 3669 pixels 4000 dpi 1.39 x 0.917 inch 92.1 mb. The size of the file on my hard drive is 119.885kb or about 119.9 mb. Why the discrepancy between what VueScan says the file size is versus the size on the hard drive? On my PC, an image reported by PSP as 26.5MB, is on the disk 26.56MB in NTFS. The size difference you describe is very large by comparison. There's always a difference between the real size of a file and the size on the drive due to the slack space in the clusters that make up the drive sectors. If you have a large drive (more than 32GB) formatted as one partition with an inefficient file system like FAT32, you may end up with cluster sizes of 32KB. So a file which was 1KB would take up 32KB because that's the smallest space that the drive format can address. This slack space can cause a difference between the actual size and the size on disk, but I can't see it making the 28MB difference you have, unless the drive is really badly fragmented. To keep slack space down, it's better to use a format that's designed for large drives such as NTFS. http://www.pcguide.com/ref/hdd/file/partFAT32-c.html Is the file size still 120MB after it is written on a CDR? I think there must be some other explanation why the size in Vuescan is reported as being so significantly differently. The only suggestions I can think of are that you are resizing the file to a larger output size, or the file you're saving is a raw file which includes a fourth infra red channel. My LS30 scans as RGB are about 27MB but are 33MB as RGBI.

I don't know why this happens, it doesn't happen all the time, and unfortunately the only thing I can do about it is avoid sending messages while logged in through that proxy. :( Further to my comment about PEC12. In the USA it's possible to get special wipes which are presoaked with PEC12. As far as I know it's not possible to get them in Australia - I had to import the bottle of PEC12 I have as it was! PEC12 is very effective at removing dirt and mould, and I am also hoping that it does a good enough job of removing mould that it discourages regrowth. However - the mould eats the emulsion so bear in mind that you may end up with blank spots on your film. It's *not* the fault of the cleaner, but the effect of the mould eating the emulsion. In some cases I would wonder whether it's better to scan the image with the mould on it, because some of the emulsion at the edges of the growth may be unstable - either way it would make sens eto do a before and after scan. PEC12 can leave a residue on the surface of the film. Other than cleaning it again with more clean PEC12 I don't have any suggestions for removing it - but others who have used it more may be able to comment. I doubt the residue would be noticeable in a scan but it *may* alter the contrast slightly. Others on the list have suggested soaking in PEC12 for particularly difficult grime. I've never tried this.

I've managed to resurrect my PC still in Win2K so I don't need to move to XP straight away. I will do so when the current project is complete (scanning pictures for a visa application) and I can afford the time to reinstall all the software.

The loss of the scans is a bummer, but at least I *didn't* lose all my emails, address book etc, and most importantly all my digital pics from the video camera which would have been gone forever. One of the downsides of going fully digital - no backup in the form of film!! The cheap SCSI cadr works with the LS30 in Win2K so hopefully it will still work in XP. It doesn't talk to the old HP Scanjet IIIc however, but the adaptec SCSI adapter on the motherboard of my old PC still does thankfully. Rob PS For anyone who upgrades to Nero 6 to do DVD data disks as a means to save scans - I didn't find the drop-down box at the top left corner of the Nero window an obvious way of selecting between CD and DVD disk types.

Some will use digital cameras, some film scanners. We get a chance to really judge the final result, the result beyond all theory, the result that we can see on paper with our own eyes! It's an interesting idea. I suspect that in a lot of cases, the details of the print (paper, printer, ink) will be more significant than the difference between a high end digital camera image and a 35mm film image. Especially if the final size of the prints are limited to say A4. Prints to larger than A4 will require scanning from 35mm at more than 2700ppi, but I suppose that's a question of categories as Yves has already suggested.

If you try to use the IR scratch removal feature on silver based BW film you may end up with a result that looks horribly out of focus. The IR feature cannot be used with silver based film, and may be problematic with Kodachrome. It should work fine with Ektachrome transparencies or dye based neg films. If the focus is also faulty with Nikonscan, there's likely to be a fault with the hardware.

Some scanners do the setpoints automatically in the scanner. Some use profiles to apply the tonal curves...

I'm not assuming any specific interface... Another question then - do you use Vuescan? Because my understanding of the original rationale behind vuescan (which has shifted a little over time) was to get the most possible useful information out of the scan, and leave the a lot of the contrast and tonal correction to editing later. Maybe Ed has changed his rationale completely over the years, but I don't recall him ever recommending that you should do all the image tonal manipulation in Vuescan and virtually none of it in an editor afterward. OK, then I think we agree? Other than what you mean by raw data. Typically, when you get high bit data from the scanner, it's raw data. Raw data specifically means the setpoints have not been set, or the tonal curves applied. What do you think raw data means? I would have taken raw data to mean exactly what it says - the bytes produced by the scanner with no manipulation whatsoever, meaning you'd have to remove the neg mask, invert and do tonal correction in an editor. Perhaps my view of raw is skewed by being a programmer or using Vuescan; whose raw files are exactly as I described above. More importantly, the raw data is useless to me if I want to take advantage of the scanner's IR dust removal feature.

[filmscanners] 24bit vs more
Unfortunately I'm not one of the lucky majority who have scanners that produce data with more than 10 bits per channel. I am still stuck with my LS30. I don't know about other scanners, but I can say that difference between scanning using Vuescan at 10 bits per channel instead of Nikonscan at 8 bits per channel makes a HUGE difference in the information I can get out of film. In particular, I find that subtle shadings of similar colour (eg. flower petals) become posterised with Nikonscan while Vuescan produces smoother results. Because Vuescan doesn't have the facilities to adjust things that Nikonscan does, I always need to do a significant amount of editing later. But Vuescan turns the LS30 into a worthwhile scanner, where with Nikonscan it's VERY ordinary indeed. My point is that for some of us, getting the data into the PC at more than 8 bits per channel makes a lot of sense. I dispute the claim that if you have to do a significant amount of adjustment after scanning that you haven't done it right. It depends on the circumstances. Getting the *right* 24 bits can sometimes better be done with an image editing program than the scanner's interface.

Re: filmscanners: Fuji 800
I just processed a roll of Fuji 800 which has both underexposed frames and overexposed frames. It should give me some idea of the difference in grain. Well, this roll of Fuji 800 doesn't seem to demonstrate the same awful grain I've seen in the past! :-7 Yes, there's quite a lot of grain, but perhaps because the photos are reasonably appropriately exposed, the results are much more useable. The photos I had trouble with before were from a Fuji 800 disposible camera taken underwater - so they were mostly very underexposed. With this film, the underexposed shots are star trails, so by the time you readjust the contrast and brightness they don't look too bad! I was momentarily excited when I picked up the roll today because I thought I had captured a meteor. Then I realised it was lens flare. :( I almost got excited again when scanned one frame - a line had appeared which was not on the print. It turned out to be a scratch. Oh well! Here's a jpeg showing small parts of two frames from the film at 1:1 from the 2700ppi scan. One shows the belt of Orion, and the other shows part of someone's face. The latter was taken with flash and the camera set to +1EV. I haven't adjusted the contrast properly in either image, so they're flatter than they should be and the grain is more obvious. In the 6x4 prints of the overexposed frames, the grain isn't particularly noticeable. The images are sharp and punchy - it's amazing for an 800 speed film. Clearly the grain would become much more obvious in larger prints. I can see why a lot of photographers who don't need big prints love this film. If anyone is interested I put together another jpeg which shows a similar sized snippet from a Provia 100F slide next to the overexposed snippet of Fuji 800.

It occurred to me to wonder whether some of the softness in the use of ICE or infra-red cleaning may be due to the difference in focus needed.

Jawed wrote: An 8-bit A/D really would struggle. I agree but it was as I mentioned, an artificial example. Maybe I should have worked with what I actually have, which is a scanner with a 12 bit A/D that the firmware drops out the 2 LSB from to return 10 bits per channel. It doesn't matter how many bits are on the A/D - it could be 32 for all it matters. What matters is how large a range of numbers is produced. With a neg film, the range will be much more narrow than a slide film. If it equates (by your estimates of 6 to 7 bits) to a range of only 5 to 6 bits of variation, the output will posterise easily. 7.x bits of scanned data are gonna be stretched a bit thin by the time the image has been decoded. Even more so when you start doing Levels/contrast adjustments or curves. Exactly. So you need as many bits per channel as possible on the input side to get the best quality at the other end. [CCD linearity] integration time. Whether this effect is ever significant is something I don't know. Really needs someone who's implemented a scanner at this level of detail to comment. In the past it's been stated on this list that the CCDs used are linear for all intents and purposes. sensitivity compressed into a much more narrow range. If you don't have enough bits, you won't get the subtle tones whichare in the film. Agreed. Though this does depend on how far from the desired result the scan is. Sure. The less you have to manipulate it, the better - yet isn't this contrary to experience? Most people seem to be saying that it's easier to get good scans from colour negs than slides, yet they require a LOT more manipulation of the data than scanning a colour slide. When you scan a true b+w film, it seems the scanner loses a very significant amount of dynamic range, a bit or more (I don't know what the mechanism for this is - is it solely because scanning is not done across the R, G and B channels - but only on, say, G?). I don't know what Nikonscan does, exactly - it seems to take the output of only one channel, and only as 8 bit data. That immediately cuts the dynamic range. Vuescan combines the colour channels into a high bit file. But AFAICS it's the density of BW film which is the problem fot a Nikon, aside from nasty interactions between the LED light and the silver grains. No, they don't. As Ed explained, they change the exposure time not the brightness of the LEDs. I believe you're misquoting Ed. No. Ed posted very emphatically that he had traced the commands used by the Nikon scanners, and they changed the integration time, nothing else. He also mentioned that changing the analog gain affected the speed of the scan. If it was LED intensity, the scan time would be unaffected. The manual says the brightness changes, too The manual is misleading. Either the tech writer was trying to explain things in photographic terms of exposure compensation or they were misinformed. Unless you mean that there is no connection between Nikon Scan's auto-exposure algorithm and LED brightness. There isn't. The LED brightness is fixed and the exposure is adjusted by varying the integration time. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

For reasons analogous to the use of 16-bit scans (really 10, 12 or 14 bits, generally): to maximise tonal smoothness and provide resilience under further editing. Maybe I'm misreading this, but something I've wondered is whether any scanners actually remap the data. It's hard to describe without a diagram - suppose you have a monochrome scanner with an 8 bit A/D. The A/D can only produce numbers from 0 to 255. If the actual image information is all between (say) 10 and 245 then you've effectively lost 8% of the resolution possible from 8 bits. But if you remap that range so that 10-0 and 245-255, you're stretching the values in between. I presume this stretching is what adjusting levels actually does. But presumably the fewer bits from the A/D, and the smaller the input range, the poorer the result would be. Does setting the black and white points cause the data to be remapped? I presume this remapping is always post A/D. Are there any scanners which attempt to adjust the input levels to maximise the range of values from the A/D? As far as I can tell, setting the black and white points in (say) Nikonscan is no different to doing the same thing to a flat file in Photoshop with Levels? BTW as far as colour shifts are concerned, I found Picture Window Pro's ability to do levels in colour spaces other than RGB helped a lot. RGB levels in PS tends to shift the colour balance, but HSL levels in PWP doesn't. What am I missing here? Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

filmscanners: Comparing the sharpness of scans
Is anyone else interested in taking a couple of photos of a resolution target to attempt to compare the sharpness of your lenses? I won't be able to compare the results of the photos I took last weekend until I finish the roll in my own camera. I just have to think of something to use 2/3 of a roll of 100F on... The photos from the Canon lenses look nice. I've scanned a couple with a SS4000 and they don't look amazingly sharper than photos from my own camera, but I'll need to scan the photos I took with mine on the same scanner to compare them side by side. One thing I noticed was that it was much easier to focus the big lenses because the viewfinder image was much brighter. I just priced a 43mm Pentax prime as an import from Japan. Much cheaper that way for me, as the Australian prices are silly. Now I just need to find US$450... Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

Laurie wrote: (spanning). I understand what RAID 1 (mirroring) is and how it works; but I really do not understand how RAID 0 works or what parallel operation of the two drives on the channel means and entails. Striping simply means that data is interleaved on different disks. In a simple two disk stripe set, you interleave between two drives. When the file is read or written, you're using both drives, so (in an ideal world) you get twice the speed of a single drive. In practice it's not quite double, but it can be close. While it may be different for third party RAID controllers, the manual for the RAID controller on the ABIT KG7-RAID motherboard says that you need 4 drives to use RAID 0+1 and that the second pair duplicate the first pair. In RAID 0/1 you have four drives - two sets of interleaved drives, with the data mirrored between the pairs. So you get the speed increase of striping plus the security of mirroring *but* you lose storage space by mirroring. If you have two 20GB disks interleaved, you get 40GB of storage with almost double the speed. Mirrored you have normal speed but greater security. To get the combination you have the expense of four 20GB drives giving you 40GB storage with security and speed. A better system with multiple drives is RAID5 where you have parity - it's a bit complicated to explain but in RAID5 any of the drives can go down and you can rebuild the data from the other drives. This sort of thing tends to be expensive to set up, just like 0/1! IMO the higher RAID types are fine for servers, but not worth the hassle for home use. I think for home/SOHO use with film scanning, go for striping to get the speed and if you're worried about security, get a tape drive for backup. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

This is true - however most of us rely on one hard drive for *everything*. Striping across two drives gives you much greater speed with no significant difference in reliability (and yes I know there's two devices involved). Personally I copy my data to CDR, and if the hard drive dies I'll have to rebuild the OS from scratch. There's better options, but the cost and hassle isn't worth it for me. I'd rather be running a two drive stripe set and halve the time I sit around waiting to load and save 27MB film scans.

Ezio, I know we've been here before, but SCSI isn't a cheap option for everyone. Certainly, if I was in the US and had access to the sorts of prices you quote from ebay, I'd use SCSI... well, there's other problems. If I wanted to use a 10Krpm SCSI drive I'd also have to fit a cooling fan in my computer and move house to somewhere that had air-conditioning.

Hi Rob! Again, I envy your opportunities for combining excitement and photography! You wouldn't envy my income from it! :) He claims that suspending the camera by the tripod is much better than using a fixed tripod that transmits the vibrations from the airplane to the camera through the tripod. That makes sense. Unfortunately due to money limitations I couldn't afford either as gyroscopic tripod or stabilisation lens. Maybe one day! Good to know about the options in any case. The best photographic platform I've flown in so far was an ultralight called a Drifter. Sitting in the front seat, the nose cone and windshield only come to about mid-chest height, so you basically have 180 degrees of unobstructed view. More if you shoot down to the left or right. The plane has a pusher prop, so it's behind you. But it's very windy, even if the aircraft only flies quite slowly compared to a general aviation aircraft like a Cessna.

filmscanners: RE: filmscanners: grain in negs/slides
Tomasz wrote: Why do scans of color negatives appear grainier than those from slides? From what I've read on this list, it's related to the exposure latitude of colour negs. To get greater latitude, the grain in neg film varies in size much more than in slide film. The very narrow exposure latitude of slide film results in more consistent grain. My experience with a 2700spi scanner is that the larger elements of the neg grain cause aliasing and makes the grain appear to be worse than it really is. Scanners with collimated light sources like the Nikons will tend to see grain more than those with diffuse light sources like the Polaroids. I haven't used a 4000spi scanner enough to know for myself, but other such as Tony Sleep have said that apparent grain in negs is a lot less with a 4000spi scanner like the SS4000 than with a Nikon scanner. Tony (and others I think) have also mentioned about the visibility of different sized grain patterns depending on how the film is exposed and developed, but I think that's an issue better covered by someone who understand the chemistry. I have always read and experienced myself that color negs are less grainy, especially in high ISO emulsions and that in slides everything above ISO 100 shows pronounced grain (ok - naow we have Provia 400F). I think virtualyl all my slide films are ISO100. As far as I can remember, I've shot one or two rolls of Kodak Extachrome push film at EI1600, and a roll of Provia 400F. I didn't mind the grain in the Provia. Ah- I've also used a couple of rolls of Kodak 320T and they were very grainy, but I expected that under the circumstance (dark stage lighting). I'm just curious what's so peculiar in film structures that different effects are achieved although both types of film use dye clouds. FWIW the different dye clouds seem to behave quite differently with light. Colour neg film grain seems to look sharper and more coarse, while slide film grain seems to look smoother. I've seen photomicrographs of Provia 100F and it looks quite amorphous. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

If you have an image that is that good get a drum scan from Nancy Scans (11,000 dpi?) or somewhere.

Re: filmscanners: Multiple passes
Ken Durling [EMAIL PROTECTED] wrote: Someone feel like expounding briefly on the multiple pass technique? It just means the scanner does several passes and combines the result. I'm using Vuescan and a FS2710, slides and both color and BW negs. What is the purpose and what determines the number of passes you set? Usually to get more shadow detail and less noise. By averaging the passes you should reduce noise and effectively increase the ability of the scanner to pick up details. But the scanner registration must be exact - the passes have to line up precisely. The Nikon LS2000, 4000 and 8000 have an advantage here because they can do multi-exposure in a single pass. Each exposure line gets done multiple times in one pass. No registration problem. I tried a couple at 2 passes, and saw no noticeable effect, although I'm not at all sure what I'm looking for. I don't know if it's terribly useful with a 2710. Any other 2710 owners use multipass? I don't use it much with my LS30, but when I have tried it the registration has been OK. It seems to cause a slight loss of sharpness, but also seems to reduce aliasing. Rob

It's the lens quality of a poor lens that would show up in a scan. Or other factors like aperture, camera shake etc. You don't need to buy a Lieca lens in order to get quality. Check out www.photodo.com for unbiased lens test data. I was pleasantly surprised to see that some Pentax lenses rated very well on that site.

Check out www.photodo.com before you buy a given lens. Makes sense. Shoot the lens under optimum conditions. If only that were always possible! My photos taken from ultralights are under pretty challenging conditions - no chance of a tripod, vibration and wind buffeting, hand held... but at least the bright conditions make a high shutter speed possible! :) Again, I take your point.

One word only: basically all 28-80 (especially those of f/3.5-5.6) are so-called kit lenses produced especially to e sold in kits with low and low-mid specified bodies. They featured by very cheap glass capable of delivering mediocre results, since the main goal of such lenses is the lowest possible price rather then quality. Sure, I'd expect that. The 28-80 zooms are essentially thrown in for free when you buy the camera. In optics the rule: you get what you pay for has almost 100 % meaning... I'm usre this is generally true, although I imagine there's such a thing as limiting returns. I find it hard to believe that the price difference between the Pentax 50mm f1.7, f2.8 and f1.4 lenses would be obvious in the results.
