This is a 6000dpi scan of a frame of Superia 1600 taken on an OM2
The advanced CCD array and XY zoom mecanism help the Cezanne Elite attain its remarkable 589 t0 5,300dpi range of scanning reolutions across the entire scanning bed.
By all accounts it does actually meet those figures in real tests.
Brocure
Well I only paid £400 for it ;-)
Wondered who had won
that a friend had asked me if they thought it was a good buy.
I'm getting a Heidelberg Tango in at the end of the year which should manage about 9000dpi
Well the manafactuers spec was
11000dpi however I recall in one test a figure of more like 5000dpi ish and a lot of people doubting that the usual arguments centre around the size of its aperatures from a post by Bruce Watson on Large Format info it has a wheel of 25 aperatures the smallest of which is 10microns now conventional drum scanner wisdom would say that limits its optical resolution to about 2500dpi however I did find a page yesterday where someone attempted to explain how it reached its claimed higher resolutions but that is not currently loading and it should be noted that they operated a service using one. Myself I don't see the Tango as the ultimate drum scanner I can however see the attraction from a comercail point of view as you can mount a hell of a lot on that drum and leave it to do its thing.
Lots of interesting debate on the merits of the Tango on LFInfo when its back up latter I'll post the links.
It's often informative / amusing to see how scanning services base their range of services around the limitations of the equitement they are using.
Are you finding the limitations of the Scanmaster 4500 irritating Tim ? They are certainly capable of good results but I found some of its limitations irritating with 10x8 and its build quality is in my opinion no where close to say the Optronics Colorgetters or Dianippion Screen scanners and I'm aware of others who switched to the Scanmate line. Just about every drum scanner has some annoying limitation hidden away in the specs.
As to size of files.
I did some mucking around with some 20 year old 35mm and a 6000dpi well ok 5950dpi (seeing as I was being anal earlier) came out about 300Mb for a 8000dpi scan the file was about 500Mb.
I don't normally scan 35mm. Size for a 5x4 scanned at 3200dpi is about 1Gb you can scan higher but I think Bruce Watson about has it right in this
disscusion on photo.net
For a 10x8 a 1600doi scan is about 1Gb I did do a stiched 3200dpi a couple of weeks ago which is where you find out that Tiff only suports upto 4Gb so I ennded up with a 9Gb PSD
Now here are some I did earlier or rather I went hunting for old negs etc, first attempt at scanning negs usinng the Screen Negacolour software which seems to have done an ok job the scans are horrible because I just nailed them to the drum currently in there and these are 20 odd years old not very well stored negatives you can click on them to get the all sizes and download the originals subject matter isn't thrilling either if I find better conditiion one I'll have a go at it later.
http://www.flickr.com/photos/abbandon/8923072709/ <-- 6000dpi or thereabouts Kodack Ektar 25 pro around 1990 so a Nikon FM2n and 35mm F1.4Ai RSM fieldtrip think its Tulle in the Limousin.
http://www.flickr.com/photos/abbandon/8923069819/lightbox/ <-- same again at a Gold mine in the area
I haven't upped the 8000dpi scan as it got attacked by the dreaded Magenta Tinge of doom which I should probably look into.
Somewhere I should have some Kodachrome 25 from around the same time but I haven't unearthed that yet so the one below acccoring to the stamp in the mount is from Aug 84 which would probably be a Nikkormat Ftn and a 50mm F2
http://www.flickr.com/photos/abbandon/8923074939/ <-- ok so I was never a fan of Kodachrome
I would say the Cezanne went for about the going rate a Howtek 4500 went for about 280 the other day I paid 685 for one in Nov 08 with mounting station and two drums and a large quantity of consumables (must get round to fixing the poxy thing).
Optronics ColorGetter II Pro was 123 can at least do 4000dpi across its whole drum but the software I have for it is 8bit and the 16bit software for it by the time you get vat and shippinng on it new would be about 850
Dianippion Screen DT-S1045AI 250 buy it now exchanged some services for another drum and a mounting station and also ended up with a mint set of Konica Hexagons as well.
Now why can't the Chinese make a scanner to give that result for £250
The Howtek was about 20 000 new the colorgetter 36 000 and the screen 56 000 Tim's Cezanne I believe was marketted for 18 000 when it was new the precision enginerring and high quality components in these is just never going to be cheap back when they could sell 500 - 2000 it was possible for firms to make these profittably now only IGC and Aztek claim to offer new Drum scanners prices believed to be about 20 - 30 000. I could be wrong but I don't think any of the pro flatbeds are still in production either. Three HV psu's and the photomultipliers new in small quantities would likely cost 3000 +
Drum scanners get given away / scrapped not infrequently fewer people know what they are or have the inclination to try then I saw 3 colorgetters II Pro's plus 2 parts machines go for less than $20 in the US a couple of years ago there was a buy it now on an 11 000dpi screen for under $500 that machine got scrapped and the seller was trying to sell the boards and manuals.
Most of these are laughingly called desktop drum scanners average ish sort of size is 4 foot by 2 foot by 2 foot and say 100Kg its a bit bigger than an Epson V750 as are the pro flatbeds I know what I would get whats a V750 now ? 650ish now that I am happy with the Screen I pobabaly haven't used the V750 since Febuary.
Health warning you may end up exposing yourself to the horror known as Mac OS9 its not nice and I never thought it was pretty myself and MAC hardware is suprisingly a lot more incompatable than people might think if people get tempted for something that will only run on OS9 and a lot of drum scanners fall into that catorgory you need to be aware that you need a Mac that will natively boot OS9 running in classic will not cut it as it will not talk to the SCCI or GPIB interface you usually need as a few pointers G4 Power Macs are a usefull buy but don't get one with a third party upgraded processor they generally need OSX best bet is the Mirrored Drive Door models as its Dram and larger drives are suported but note that the firewire 800 one of then will not natively boot OS9.
