So, I guess all of this means that I can postpone ordering a Coolscan V for the time being?
The following page might be helpful: This is the great scanner comparison.infrequent said:i am looking into buying one of those plustek 7200. seems very good value for money. there is a plustek 7200 group on flickr if you wanna judge yourself.
Those are not "real" dpi, but only "nominal" dpi. The 5400's resolution is below 4000dpi.amateriat said:Oh, dear. Let me see if I can help things out here...
Firstly, while the Minolta 5400 (I) isn't the swiftest boat in the fleet, I've gotten scan times of about 7 minutes average, at maximum resolution, with ICE engaged (Power Mac G4, dual 1.25GHz, 2GB RAM, several big, fast internal HDs, FireWire connection to scanner). Sometimes the scans are actually faster, sometimes slower. And, while I wouldn't regard a 10-minute scan as fast, what would this be compared to, a 4000dpi scanner? I'll trade a few minutes scan time per frame for that extra 1400dpi without question. Your priorities may vary. 🙂
You're referring to the manufacturer's implementation of ICE and not VueScan's "Infrared Cleaning", right?And: I have scanned Kodachrome with ICE, and, in my opinion, It Depends. Depending on age (and Dog knows what else), some K'chromes manage "okay" via ICE, while some do badly. Verdict: when in doubt, scan it without ICE, and do the retouching grunt-work yourself.

This has been bandied about, but I've yet to see it substantiated. "Not real" might suggest interpolation, but from my own experience I don't see it.R2-D2 said:Those are not "real" dpi, but only "nominal" dpi. The 5400's resolution is below 4000dpi.
Yep, although I've also used VueScan. Generally speaking, running K'chrome through ICE, IMO, isn't a great idea, so I'm with you (and the manual) on that 🙂You're referring to the manufacturer's implementation of ICE and not VueScan's "Infrared Cleaning", right?
One other factoid to take in is that this company's previous top-end scanners had an optical-resolution spec of 3600dpi. Not to rain on anyone's parade, but what does the spec sheet on the 7200dpi model actually spell out?venchka said:IF those three things were possible, 7200 dpi-48 bits AND a sales price of $200, don't you think everyone would be making them? As things stand today, there is no independent testing and verification of scanner resolution. The builders can claim anything they like. For what it's worth, most consumer flatbed scanners max out between 2100 & 2400 dpi REAL OPTICAL resolution.
Regarding dedicated film scanners, I wouldn't suggest postponing anything if funds allow. That's just the way things are now.dexdog said:So, I guess all of this means that I can postpone ordering a Coolscan V for the time being?
No, the 5400dpi are not interpolated. The stepper and the CCD unit just aren't capable of resolving 5400dpi. The measured resolution (USAF-1951) for the 5400 II is 4598dpi horizontally and 3649dpi vertically according to this test:amateriat said:This has been bandied about, but I've yet to see it substantiated.

The 5400 I(!) might be the best scanner (without Digital ICE Professional as found in the Nikon 9000) for trying to scan Kodachrome slides with ICE, because of it's integrated "Grain Dissolver" (which, when used, automatically enables ICE). Diffuse light sources are supposed to work better with B/W negs and Kodachrome slides.Yep, although I've also used VueScan.

FWIW, I believe I read not too long ago that they now support the Mac. Oh yeah....sitemistic said:The Plustek's are PC only, aren't they? Or did they ever get MAC drivers?
They have all the detail of higher-spec scanners (e.g. Coolscan V), able to fetch from a good neg more than an average user is ever willing to print. Their main weakness is low DMax, sufficient for well-exposed stuff but struggling in extreme cases.myoptic3 said:They don't have the detail of the higher priced film scanners, but not bad at all.
