Kusarudza scanner kuti firimu: anobatsira mashoko

Kutendeutsa negatives kana masiraidhi kuti digitaalinen Manyorerwo vachishandisa chaiyo mudziyo - mumwe scanner kuti firimu. Zvakasiyana kubva kwakajairika scanner zvakagadzirirwa kubata duku segirazi mifananidzo, vane yakakwirira chisarudzo. Kunyange zvazvo dzakawanda scanners flatbed takashongedzerwa chaizvo modules, kunoita kuti atarise masiraidhi, asi chigadzirwa inotengwa somugumisiro chenhando.

Chete CCD (CCD) kushanda pakuvheneka zvinhu anogona kupa zvaida kudzama munda mifananidzo dzakakwirira resolution. Naizvozvo, scanners zvose Makavakwa pamusoro firimu avo kushandiswa. Vamwe mhando vane chete CCD mutsetse. Panyaya iyi, iyo digitization zvaida pemipata nhatu kubudikidza kunaka. It kunosvika Ongororo, asi asingaiti kukanganisa mugumisiro. Zvikurukuru, firimu scanner ane CCD wakazvigadzira, uye digitizing mufananidzo kunoitika nenzira chete zvichipfuura. Vamwe mhando vanoshandisa reusable vanopfuura kuderedza zvikanganiso ari mufananidzo wokupedzisira.

An parameter inokosha yaunofanira kuteerera pakusarudza scanner ndiye Manyiminya resolution. Upamhi nevakariri firimu iri 35 mm, uye mufananidzo pacharwo kukura kunyange chiduku. Naizvozvo, nhamba yemabhuku Manyiminya chisarudzo chinofanira kanenge 2400 DPI (Dots muzana padiki). Pane scanners kuti anopa 4800 uye 5400 DPI. Kunyange zvazvo mamiriro nenhanho zvigadzirwa kuzadzisa kunyange yepamusoro tsika, zvisingaiti - upfu tsanga kukura firimu uchava zvakawanda pixels.

Cherechedzai inofanira kubhadharwa kune simba siyana kana Manyiminya arambe achirema. The yepamusoro mutengo, nani scanner anogona kuparadzira rasterointi negatives kumeso ruvara kuchinja. For Qualitative kukosha Manyiminya arambe achirema firimu kubudiswa inofanira kuva kuwanda anosvika 3,2 D 3,6 D. Wana muenzaniso rukuru Manyiminya arambe achirema hazvina musoro, sezvo ruzhinji mafirimu akadaro rinokosha.

The chatingatevedzera digitization zvakunoita vo zvishoma kumiririrwa munyika, iyo inechirevo ruvara kubereka. Modern scanner firimu anogona 42 kana 48 ikakuruma ruvara amiririrwe, asi mune pamanyorerwo kubudiswa rinoshandiswa chete mukati scanner, uye anoshumira kuderedza "ruzha" kushanduka. The zvichiguma mufananidzo une mureza 24-ikakuruma ruvara yeEncoding zvokushandisa kombiyuta.

Scanner nokuti masiraidhi kakawanda chokuita kuti kombiyuta vachishandisa USB-inowanikwa. More mhando zvinodhura inogona kwakabatana Via SCSI-2 uye IEEE 1394 (FireWire). Muchiitiko chino, kazhinji zvakakwana yaisanganisira ndiro kadhi pamwe date controller.

Scanner firimu dzinenge nguva dzose ane mashoko Hardware kuti mufananidzo enhancement. This Digital chando, izvo zvinoita kuti kubvisa mufananidzo huruva uye anokwenya, pasina kukanganisa mufananidzo mukuru, uye Digital Chanchikwan, izvo anobvumira kubvisa graininess uye Digital Roc, vachibvumira kudzoreredza ruvara kuti vachatorerwa ruvara mifananidzo uye nevamwe. Kazhinji, nzira idzi ikashandiswa mune imwe pasuru Digital ICE4 Advanced. Kushandisa ruzivo izvi kunowedzera zvikuru Ongororo, asi mugumisiro wakanaka. Nokuti zvakafanana transformations muna Photoshop zvinoda nguva yakawanda, uye mugumisiro haisi kodzero.
