Umboni Wofewa Kuti Mukwaniritse Mitundu Yofanana Kwambiri Paintaneti komanso mu Photoshop

Kungoganiza kuti mumasintha zambiri pazithunzi zanu Adobe RGB kapena ProPhoto RGB (malo amtundu wa LR), muyenera kusintha zithunzi zanu musanatumize patsamba lanu kapena blog.

Kutsimikizira mofewa ndi njira yothandiza kuwonetsetsa kuti kutembenuka kwanu kudzawoneka momwe mumafunira mukadali mukugwiritsa ntchito zithunzi zanu. Njirayi imagwira ntchito pazotsatira zingapo (ie CMYK komanso mawindo osasintha a Windows ndi Macintosh).

Mutha "kutsimikizira mofatsa" kutembenuka kwanu mwa kupita ku View> Proof Colours (Cmd + Y pa Mac, Ctrl + Y pa PC) kapena Proof Setup, ndikutsatira posankha imodzi mwa Standard Mac / Windows Mbiri (kusiyana kokha pamenepo monga momwe ndikudziwira ndi Gamma; 1.8 vs. 2.2).

Nachi chithunzi changa choyambirira chomwe ndikuyamba kugwira ntchito ku Photoshop.

Malo anga ogwira ntchito a RGB ndi sRGB, koma fayiloyi ili ndi malo a Adobe RGB. Mutha kudziwa chifukwa mawu omwe ali pamutu wazithunzi amasintha, ndipo tsopano ali ndi asterisk pafupi ndi RGB / 8:

Kuti "ndikhale ndi umboni wofewa", ndikupita ku View> Proof Setup…> Mwambo…

Bokosi lotsatirali litsegulidwa:

Onetsetsani kuti mwasankha "sRGB" mu Chipangizo Chotsanzira, ndipo onetsetsani kuti mwasankha "Sungani Manambala a RGB." Ngati simutero, mutsimikizira momwe zingawonekere ngati mungatero zopatsidwa mbiri m'malo mwa kusintha kwa imodzi. Izi ndi zomwe chithunzi changa chikuwoneka ndikasiya bokosilo litasankhidwa:

Sindikusowa kuti ndikuuzeni momwe chithunzichi chikuwonekera moipa kwambiri; wataya kusiyanitsa ndi kukhutitsa. Ndipo muchenjezedwe, izi zikuyimira zomwe zimachitika ngati mungasunge fayilo yanu ndi mbiri ya Adobe RGB yolowetsedwa m'malo mwa sRGB pa msakatuli yemwe sangathe kuzindikira mawonekedwe amtundu (IE, imodzi). Tiyenera kuwonetsetsa kuti izi sizichitika pazithunzi zanu, pokhapokha mutakhala kuti mwatsatira. Ndimakonda zithunzi zanga zabwino komanso zodzaza ndi thanzi labwino!

Sankhani "Relative Colourimetric" poperekera Cholinga, ndipo onetsetsani kuti Black Point Compensation yasankhidwa. Izi zidzaonetsetsa kuti mukugwiritsa ntchito mtundu wamitundu ikuluikulu potembenukira ku sRGB. Mutha kuwerenga zambiri zamitundu ingapo yoperekera cholinga mu Adobe's Online Help Center:  Kuthamanga mu Photoshop

Mukamaliza kuchita izi, yambitsani umboni wanu wofewa ndi Cmd + Y (Mac) kapena Ctrl + Y (PC), kapena posankha View> Umboni Wotsimikizira:

Tawonani zomwe zikuchitika tsopano pamutu wazithunzi wa chithunzichi:

Imeneyi ndi njira yachangu kwambiri yodziwira ngati chithunzi chomwe mukuchiwonacho sichinali chofewa kapena chithunzi choyambirira.

Ngakhale izi zikukuwonetsani chinthu chomwecho monga chithunzi cha "optimized" mu bokosi la Save For Web dialog box, ndichosavuta chifukwa chitha kugwiritsidwa ntchito nthawi iliyonse mukamagwira ntchito, kapena nthawi iliyonse mukafuna kuwona ngati mtundu wina onetsani mu sRGB monga momwe zimakhalira mu Adobe RGB kapena ProPhoto RGB.

Muthanso kugwiritsa ntchito njira yofewetsayi poyesezera Windows Monitor (Gamma setting ya 2.2) kapena Macintosh Monitor (Gamma setting ya 1.8). Sindikulimbikitsa kuti mugwiritse ntchito "Monitor Colour" chifukwa imakhazikitsira pazowunika zanu zokha, chifukwa chake sizingasunthire bwino kwa owunikira ena, omwe atha kukhala osakwanira kuposa anu.

Nazi zina zambiri zamitundu yofewa yochokera ku Adobe: Umboni Wofewa

Njira ina yosangalatsa yowonera ikhoza kupezeka mu bokosi la Save For Web. Pali menyu omwe akutsikira kumanzere kwa bokosilo omwe angakuthandizeni kuti muwone chithunzichi mkati mwa msakatuli womwe mwasankha:

Ndalongosola mndandanda wa asakatuli atatu omwe ndimakonda kugwiritsa ntchito pa Mac, koma mutha kuwonjezera asakatuli ambiri momwe mungakondere pamndandanda, kuphatikiza IE mu Windows. Izi zikuthandizani kuti muyese asakatuli angapo kuti muwonetsetse kuti mawonekedwe amtundu wanu akulemekezedwa m'masakatuli ambiri momwe angathere.

Onetsetsani kuti mwasiya "Embed Colour Profile" yomwe yasankhidwa, kuti munthu amene akuyang'ana tsamba lanu kapena blog agwiritse ntchito Firefox 3 kapena Safari, azikhala ndi mbiri yanu yamtundu woyenerera bwino msakatuli.
