Algumas fotos de scanners iguais ao meu :
O meu traz dois alimentadores, como este:
Comprei-o usado por 50 contos ha mais de 10 anos ... e cheguei a fazer algumas digitalizações na altura, e era bastante lento, talvez 1 minuto ou mais por cada imagem (com resolução elevada).
O PC era um PIII e a interface é SCSI ... talvez num pc recente seja bem mais rapido...
Tenho-o parado e encaixotado há uns 8 anos, pois ando à espera de ter tempo para me dedicar à digitalização dos milhentos negativos de fotos que tirei com a minha canon EOS 500N .... sendo que muitos deles nem nunca os vi em mais do que negativos, pois não havia dinheiro para revelar tudo
Uma coisa fantastica neste nikon - e que provavelmente causa parte da lentidão - chama-se digital ICE . Quando está ligado remove a maioria dos riscos, poeira e danos do negativo . Penso que alguns scanners mais recentes voltaram a usar esta tecnologia ... salvo erro até o Epson V500 faz isso ...

Exemplos do que o digital ICE faz
Enquanto escrevo isto, li que ha quem diga bem do ICE, e quem diga mal, por exemplo:
For me a scanner is used purely to capture the most detail from a print, negative or slide. I have ICE available on my slide scanner & flatbed but never use it as the process will always modify the image which defeats the object. The introduction of content aware tools in CS4 & 5 make repairing/editing old photographs so much easier, scratches and other marks can be removed in seconds without any impact on the rest of the image.
Será que o ICE é algo fisico , ou é algo que qualquer software pode fazer posteriormente ?
Alguns samples de fotos digitalizadas com o Coolscan III
Ha muita discussao na net sobre estes scanners da nikon ... pelos vistos ao fim de uns anos precisam de ser desmontados para limpar as lentes:

E pelos vistos ha quem consiga usar com sistemas operativos recentes, por ex "The images it produces exceed in quality more expensive flatebed scanners. "I am using it with WINDOWS 7 64 bit with VUESCAN. "
Pelos vistos o Vuescan é um plugin à parte...
Ta aqui alguem a dizer que consegue melhores resultados do que com um epson V300..
Nikon Coolscan III. A almost prehistoric dedicated filmscanner. This device is more than 10 years old but almost unused. Operated with an old computer under Windows NT.
Tiff file postprocessed in Lightroom 3.
Scanner testing with a borrowed negative. The Nikon Scanner only supports 2700 DPI. But I get a lot more details than from my Epson V300 when it claims to use 4800 DPI.

E a explicarem o processo de limpeza:

No fundo a minha duvida é o que fazer às centenas de negativos que tneho num dossier, a aguardar por digitalização - E que se vão detioranto à medida que os anos estão a passar ...
O Nikon é lento ... mas valerá a pena quando comparado com os scanners da Rollei ou Epson que coloquei no post anterior ?
Acho bastante atraente o facto de o Epson V500 fazer logo 12 negativos de cada vez assim despacharia o trabalho num instante
Tenho ainda um scanner destes na Epson, de uma gama de preços superior ao V500, mas é um scanner documental ... será que haverá forma de digitalizar 35mm com isto / ficaria alguma coisa de jeito ?
E dai talvez não, pois os Specs do GT-1500 são bastante inferiores aos V330 e V500 em termos de resolução...
