Dimage Scan MultiPro Micro-banding

The “thin red line” problem, and a solution

in Scanning , Saturday, July 23, 2011

After 10 years or so of pretty constant use, I’m beginning to get the hang of my Minolta MultiPro film scanner. Having very belatedly discovered Scanhancer inventor Erik de Goederen’s tip for making a single-sided glass film holder, I’m also getting something close to dust-free scans. So naturally, now was the time for the Minolta to blow a gasket.

Well, fortunately it seems to be a fairly minor gasket, and in fact I may be lucky to have only been hit by it now, because it has a name in the MultiPro community: micro-banding. Somebody even built a Photoshop plug-in (Windows only) to fix it, way back. Actually I think it is more of a stuck pixel, or whatever passes for that, as the effect is of a single-pixel wide red line right across the scan. It is strange that it’s always red though.

the red line, aka “micro banding”


The fix is actually pretty simple, so you don’t need a plug-in. Before you do any other editing - and especially rotating - simply zoom in at 100% and select a thin rectangle, say 5 pixels high, all the way across the image, with the red line centered. Then select the red channel only. Then apply the Dust & Scratch filter with settings Radius 2, Threshold 2 or thereabouts.

It doesn’t completely go away, but you’re never going to see it at anything less than serious pixel-peeping level, and certainly not on a print.

I don’t know why it hit my scanner now. Could be old age. Could be dust, although I’ve opened it up for the first time ever, and it is remarkably clean inside. Could be because I’ve been fiddling around with fluid mounts. I don’t know, I just hope it doesn’t spread, because there’s essentially nothing available to replace it.

Silverfast announces version ... 8!

Silverfast 7 reported missing

in Silverfast , Wednesday, July 20, 2011

With Mac OS X Lion and new MacBook Airs released today after weeks of speculation, today was a good day to bury bad news in the tech world.  So Lasersoft, God bless ‘em, chose today to announce, at long, long last Silverfast 8, the next major iteration of the venerable Silverfast: 

SilverFast, the most popular scanner software in the world, is released as brand-new version SilverFast 8. After many successful years, SilverFast will be available completely renewed towards the end of August for the most important scanners of all major manufacturers.

I guess Silverfast 7 was dropped in the Baltic Sea or something, since we’re jumping straight from 6.x to 8, or maybe it’s just in recognition that nobody could possibly make us wait this long for a new version.

So, we’re promised such joys as a new user interface (let’s hope they didn’t hire PhaseOne’s designer), multitasking (gasp) and much goodness. The bit that leaves me a bit worried is “for the most important scanners of all major manufacturers”.  The place of the Minolta Dimage MultiScan Pro in that august assembly must be less than guaranteed.

Well, I for one am looking forward to this more than OS X Lion.

Old Ways

Back to the Country

in Film , Saturday, July 09, 2011

Today was SWISS HARLEY DAYS (well one of them) in downtown Lugano. Yay. I don’t like Harleys, mainly because of the obnoxious and totally unpleasant noise they make. But I had to go downtown anyway - ironically to go the chemist to try to find something to stop me making obnoxious and totally unpleasant noises while I sleep - so I didn’t have much choice but to grin & bear it. And the streets were crawling with Harleys, Harley Guys, Harley Chicks, and people selling pretty much anything with Harley branding.

Great opportunity for street shooting, no ?

Well yeah, but I don’t do street shooting.

So just for a complete change, since I decided to do some street shooting, of Harleys, why not throw in another spanner and dig out my long-retired Canon A1, put a roll of slightly out of date Ektar 100 in it, and bolt my rediscovered 50mm f1.2L on the front ? And so I set off.

Canon a1

Terrible iPhone photo…but rather gorgeous, isn’t it ?

I took me a little while to get into the groove, but I soon got back into it. Frames 14, 15 & 16 have some great shots featuring bits of a bikini-clad biker chick posing for all and sundry on a very impressive Harley. Unlike the slobbering mob focusing on her more obvious attributes, I went for close up, f1.2 gorgeous-detail. Frame 15 features a close up of the tattoo on her ankle against some detailing of the bike’s chrome. Awesome.  Frame 17 is a KILLER. I got a large Harley dude with a patch saying “great legs, what time do they open ?” on his leather jacket, with the patch in the foreground, and her legs, which did indeed match said criteria, in the background, lying on the Harley. WHOA! I’m motoring here.

Well, of course I would have been if the camera had been switched on.

It’s simple, shooting with film, isn’t it ? Just set the aperture, set the speed, focus and click. Bingo. Well yeah. If, that is, you remembered to turn the thing on. Unlike my digital wonderboxes, or indeed my XPan, the A1’s shutter will fire with the camera - and hence the meter - switched off. I’m not sure why. There’s no control over shutter speed, or is there ? Can’t remember.  I’m not sure why I didn’t realise there was no meter display, either. So, after frame 18, I switched it on.

Oh well. Back to the hot chick, who is starting to look a little concerned at this weirdo with the antique camera.  The rest of the roll was sort of ok, but really not as inspired. What the hell, I’ll rewind it and take it the last surviving 1-hour shop.

Oops. Seems I didn’t quite remember how to load a roll of film into an A1.  Oh well. Again.

So I went home and did a bunch of chores, for example lying on the couch thinking about what part of the gardening to do.

And later I went back into town with two more rolls of Ektar, the first properly loaded, camera switched on, Av mode, ready to rock.  The hot girl was looking a bit frazzled by now (it was a hot day) but was still game and so was I, but the bikes and been moved around and the geometry wasn’t there any more. Nevermind, I still took a few shots, and then wandered off to take some details of bikes, and some more street shots, including a nice candid of two pseudo-Angels. At least I hope they were pseudo.

And then I came home. And I decided to write this post. And I took the photo above. And while fooling around with the A1, I noticed that the aperture on the 50mm seemed to be stuck wide open, as it was when I first tried to put it on my E-P2.  Oh well once more. At least a good number of shots were at f1.2, so I guess something will have worked.

But in any case, it was really, really fun using this camera again. I felt, I dunno, somehow sleek and graceful (ha!) compared to all these people lumbering around with huge DSLRs, constantly chimping, photographing from 2 miles across the street with zoom fully extended.

Film is fun. Even when it doesn’t work. Oh, and Harleys are ok, too.

New Medium Format film scanner

Reflecta throws out a lifebelt

in Film , Thursday, June 30, 2011

For those of us still in the Stone Age of film, and slide film at that, there’s a lot to worry about. Dwindling film supplies and variety, processing labs dropping like flies, and especially that day when the film scanner goes bleeeeeep-kerTHUNK. And then it’s Game Over, unless of course you’re willing to sell your soul to Hasselblad for a Flextight. The last (and first, really) wave of affordable, high quality medium format scanners from Nikon, Minolta, Polaroid and Microtek are fast approaching Lights Out. But remarkably, a potential saviour has arisen in the shape of Germany’s Reflecta. Although they’re probably not well known outside of Central Europe, Reflecta is a company with a long history. Typically they’ve made various low to mid-range accessories and devices, including slide projectors (I believe some Leica slide projectors were rebadged Reflectas) and cheap and cheerful 35mm film scanners. However, as the mid to semi-pro market collapsed, Reflecta has been cautiously and quietly edging upwards, acquiring a credibility-enhancing partnership with Silverfast on the way, as well as some encouraging reviews. Although the fact that they have practically no credible competiton must help. And now, well they’ve taken the major step of announcing their first medium format scanner.

And note, unlike any of it’s comparable predecessors it goes up to 6x12. It doesn’t appear to have a dedicated 35mm panoramic holder, but I guess one can be cobbled together.

On paper the specifications look modest. A DMax of 3.6 (I wonder how many people remember what that means) and an optical resolution of 3200dpi. Probably enough, and actually probably closer to the truth than claims of 4800dpi and similar, but not terribly exciting for the marketing men. But then it doesn’t need to be. It has no competition whatsoever, if you discount worn out overpriced eBay fodder.

From pre-release photos it appears to have a mechanism and construction similar to the Microtek / Polaroid 120 scanner, with a moving holder and fixed sensor, which is a pity. Moving sensor systems generally provide a much better platform for multisampling.

It is due to be available in July, but so far no pricing has been announced. I would expect something in the range of €1000, but I suppose it could be higher.

And will it be any good? Well, we’ll have to wait and see. But with the alternative being Nothing, I suppose the bar’s not set too high.

Ethical quandry

to edit, or not to edit ?

in Film , Saturday, May 21, 2011

I recently spent some time on the Eolian Islands, out of season, avoiding the (extreme) heat and the tourists. While I was there I visited one of my favourite locations, the main crater of Vulcano, a couple of times.

I was to find that since my last visit, the crater floor had been adorned by some “urban art” in the form of stones spelling out various declarations.

Vulcano crater scan

Straight from the scanner: the crater floor

I don’t really want to start a rant about this. Some people will find it unacceptable, to the point of wanting the perpetrators skinned alive (and they’ll likely as not have British or German passports), others will just take it as part of the scenery, others will find it amusing. The question is, should I include it in my photograph ? Certainly the last I time I visited, it wasn’t there, or at least if it was I didn’t notice, so it wasn’t in my pre-conceived photo either.

Vulcano crater scan zoom

Not quite what I had in mind

So should I edit it out ? It’s not a very challenging task in Photoshop CS3. Possibly even less so in CS5. But is it “cheating” or “wrong” ? It is after all a fairly major part of the scene, and there’s a very long tradition of graffiti in the Mediterranean area. Pompeii, for example, has plenty. So in fact it could be considered to augment the interest.

To start off with, I didn’t think too much of it. I’d decided right from the outset that first I was going to edit it out, and second, most probably, it was going to be converted to black and white. Like this:

Xpan vulcano11 2 07

What I had in mind

Apart from any ethical issues, am I actually playing it safe and traditional here, and churning out yet another boring, bland photo with nothing to say for itself ? Justified, worthwhile edit - or lost opportunity ?

I’m really not so sure…
