Post by z***@gmail.comSto scannerizzando vecchie diapositive con un V600 e software in dotazione ho impostato profondità colore 48-bit e risoluzione 2400 dpi.
Sono impostazioni corrette o è meglio cambiare qualche cosa per esempio 6400 dpi?
Lo scanner arriva fino a 12888 dpi ma credo che fino a 6400 siano reali poi sono interpolati.
Grazie per l'aiuto
Ciao,
io dopo i deludenti risultati ottenuti con un Canon 8800F avevo guardato
su questo sito, che mi sembr ail più autorevole sugli scanner per film:
http://www.filmscanner.info
(In alto puoi scegliere la lingua e c'è anche l'inglese e il francese se
non sei avvezzo al tedesco).
Per il V600 riporta:
But how does it look like with the higher resolutions that are important
for the scanning of the film material? In our testscan done with the
USAF test chart with the V600, the vertical lines of the element 5.2.
and the horizontal lines of the element 4.5 are barely recognizable.
According to our resolution table, an effective resolution of 1560ppi
results from that. This is less than a quarter of the resolution of
6400ppi declared by the producer. This is much too less for high quality
scans of negatives or slides! For the 35mm format, some image files of
only approximately 3,6 megapixels result. Any modern digital camera
performs considerably more. The Canon CanoScan 8800F achieves
approximately the same resolution. But there are also good news: In
order to achieve the maximum resolution of 1560ppi, one does not have
only to scan the with the highest optical resolution but it is
sufficient to digitalize the original with 3200ppi. The effectively
achieved resolution does not differ, no matter if one scans with 3200ppi
or with 6400ppi - in both cases, an effective resolution of 1560ppi will
be achieved! By this way, it does not make sense to scan with the Epson
Perfection V600 Photowith 6400ppi.
