I-wand wand - elinye lamathuluzi "ahlakaniphile" ku-Photoshop yohlelo. Isimiso sesenzo sinokukhethwa okuzenzakalelayo kwamaphikseli wezwi elithile noma umbala esithombeni.
Ngokuvamile, abasebenzisi abangayiqondi amakhono nezilungiselelo zethuluzi badumala emsebenzini wakhe. Lokhu kubangelwa ukubonakala kungakwazi ukulawula ukukhethwa kwethembo ethile noma umbala.
Lesi sifundo sizogxila ekusebenzeni "I-Magic Wand". Sizofunda ukubona izithombe esisebenzisayo ithuluzi, kanye nokwenza ngokwezifiso.
Uma usebenzisa i-Photoshop version CS2 noma ngaphambili, "I-wand wand" Ungayikhetha ngokumane uchofoze kwisithonjana sayo ngakwesokudla. Esikhathini se-CS3 version, ithuluzi elisha livela, libizwa "Ukukhetha okusheshayo". Leli thuluzi lifakwe esigabeni esifanayo futhi ngokuzenzakalelayo kuboniswa kubha yamathuluzi.
Uma usebenzisa inguqulo ye-Photoshop ngaphezu kwe-CS3, kuzomele uchofoze kusithonjana "Ukukhetha okusheshayo" futhi ohlwini lokudonsa olutholayo "I-wand wand".
Okokuqala, ake sibone isibonelo somsebenzi Magic Wand.
Ake sithi sinesithombe esinjalo ngesizinda se-gradient kanye nomugqa ohamba phambili we-monochromatic:
Ithuluzi lithwala endaweni ekhethiwe lawo maphikseli okuthi, ngokusho kwe-Photoshop, analo ithoni efanayo (umbala).
Lolu hlelo lunikeza amanani adijithali emibala bese ukhetha indawo ehambelana nayo. Uma le ndawo inkulu kakhulu futhi inokugcwaliswa kwe-monochromatic, khona-ke kulesi simo "I-wand wand" kubaluleke kakhulu.
Isibonelo, sidinga ukugqamisa indawo eluhlaza okwesibhakabhaka kusithombe sethu. Konke okudingekayo ukuchofoza inkinobho yegundane lesokunxele kunoma iyiphi indawo yebha yombala obomvu. Uhlelo luzonquma ngokuzenzekelayo inani le-hue futhi lilayishe amaphikseli ahambisana nalesi silinganiso endaweni ekhethiwe.
Izilungiselelo
Ukubekezela
Isenzo sangaphambilini sasicacile, ngoba isakhiwo sasine-monochromatic fill, okungukuthi, kwakungekho nezinye izithunzi eziluhlaza okwesibhakabhaka emgqeni. Kuzokwenzekani uma sisebenzisa ithuluzi ku-gradient ngemuva?
Chofoza ku-gray area endaweni ye-gradient.
Kulesi simo, lolu hlelo luhlonze ububanzi be-shades eseduze kakhulu nombala ompunga kusayithi esichofoze kuso. Lolu hlu lubhekwa izilungiselelo zensimbi, ikakhulukazi "Ukubekezela". Isimiso sisesibha yamathuluzi phezulu.
Le parameter inquma ukuthi mangaki amazinga isampula angase ahluke (iphuzu esichofoze ngalo) kusuka emthunzini ozolayishwa (okugqanyisiwe).
Esikhathini sethu, inani "Ukubekezela" isethwe ku 20. Lokhu kusho ukuthi "I-wand wand" engeza ekukhethweni kwe-shades 20 emnyama futhi elula kunesampula.
I-gradient esithombeni sethu ifaka amazinga angu-256 wokukhanya phakathi komnyama nomhlophe ngokuphelele. Ithuluzi liqokomile, ngokuhambisana nezilungiselelo, amazinga angu-20 wokukhanya kuzo zombili izinkomba.
Ake, ngenxa yokuzama, zama ukwandisa ukubekezelelana, uthi, kuya ku-100 futhi uphinde usebenzise "I-wand wand" kuya ku-gradient.
Nge "Ukubekezela"ekhulisiwe izikhathi ezinhlanu (uma kuqhathaniswa neyaphambilini), ithuluzi liqokomise le ndawo izikhathi eziyisihlanu ezinkulu, ngoba hhayi ama-shade angu-20 ayengeziwe ku-value yesampula, kodwa 100 ohlangothini ngalunye lwezinga lokukhanya.
Uma kunesidingo ukukhetha kuphela umthunzi lapho isampula ihambelana khona, khona-ke inani lokubekezela lihlelwe ku-0, elizofundisa uhlelo lokungafaki noma yikuphi amanye ama-shades ekukhethweni.
Uma inani le "Ukubekezela" 0, sithola umzila omncane wokukhetha onomthunzi owodwa ohambisana nesampula esithathwe esithombeni.
Izincazelo "Ukubekezela" ingafakwa ebangeni kusukela ku-0 kuya ku-255. Okuphakanyisiwe ngale nani, indawo enkulu izokhethwa. Inombolo 255 ekhonjiswe ensimini yenza ithuluzi likhethe sonke isithombe (ithoni).
Amaphikseli akhona
Uma ucabangela izilungiselelo "Ukubekezela" Umuntu angabona isici esithile. Uma uchofoza i-gradient, uhlelo lukhethiwe ngamaphikseli kuphela ngaphakathi kwendawo ehlanganiswe i-gradient.
I-gradient endaweni engaphansi kwesiqephu ayifakiwe ekukhethweni, nakuba ama-shades kuso afana ngokuphelele nesigaba esingenhla.
Esinye isilungiselelo sethuluzi sinesibopho salokhu. "I-wand wand" futhi ubizwa "Amaphikseli aseduze". Uma ubusuku bubekwe eceleni kwepharamitha (ngokuzenzakalelayo), lolu hlelo luzokhetha kuphela lezo pixel ezichazwe "Ukubekezela" njengelungele ububanzi bokukhanya nomthunzi, kodwa ngaphakathi kwendawo eyabiwe.
Amanye amaphikseli afanayo, ngisho noma echazwa ukuthi afanelekile, kodwa ngaphandle kwendawo eyabiwe, ngeke awele endaweni elayishiwe.
Esimweni sethu, yilokho okwenzekile. Wonke amaphikseli afanayo ngaphansi kwesithombe ayenganakwa.
Sizoqhuba esinye isilingo bese susa ibhokisi lokuhlola eliphambene "Amaphikseli ahlobene".
Manje chofoza engxenyeni efanayo (engenhla) ye-gradient. "I-Magic Wand".
Njengoba sibona, uma "Amaphikseli aseduze" wonke amaphikseli esithombeni afana nemigomo avunyelwe "Ukubekezela", izoqokonyiswa ngisho noma ihlukaniswe nesampula (itholakala kwenye ingxenye yesithombe).
Izinketho eziphambili
Izilungiselelo ezimbili zangaphambilini - "Ukubekezela" futhi "Amaphikseli aseduze" - yizona ezibaluleke kakhulu ekusebenziseni ithuluzi "I-wand wand". Noma kunjalo, kunezinye, nakuba zingabalulekile kakhulu, kodwa futhi nezilungiselelo ezidingekayo.
Uma ukhetha amaphikseli, ithuluzi lenza lokhu ngezinyathelo, usebenzisa ama-rectangles amancane, athinte ikhwalithi yokukhethwa. Kungase kubonakale imiphetho enamahlombe, evame ukubizwa ngokuthi "isiteji."
Uma isakhiwo esinomumo ovamile wejimethrikhi (quadrangle) sigcizelelwa, inkinga enjalo ingase ingavezi, kepha uma ukhetha izingxenye zesikhala "esingenalutho" esingafanelwe, azikwazi ukugwema.
Amaphethelo amancane ahlelekile avulekile azosiza "Ukumangalisa". Uma ngabe ubusika obuhambisanayo bubekwe, i-Photoshop izosebenzisa ukufiphaza okuncane ekukhethweni, cishe kungabi nomphumela kukhwalithi yokugcina yamaphethelo.
Isimiso esilandelayo sabizwa "Isibonelo esivela kuzo zonke izendlalelo".
Ngokuzenzakalelayo, i-Magic Wand ithatha iphethini ye-hue ukuze ukhethe kuphela kwisendlalelo okwamanje esikhethiwe ku-palette, okungukuthi, esebenzayo.
Uma uhlola ibhokisi eceleni kwalesi silungiselelo, lolu hlelo luzothatha ngokuzenzakalelayo isampula kuzo zonke izendlalelo zedokhumenti futhi lufake ekukhethweni, okuholwa "Ukubekezela.
Hlanganisa
Ake sibheke ngendlela efanele ngokusebenzisa le thuluzi. "I-wand wand".
Sinesithombe sokuqala:
Manje sizobe sithatha indawo yesibhakabhaka ngeyethu, equkethe amafu.
Ake ngichaze ukuthi kungani ngithatha lesi sithombe esithile. Ngoba kuhle ukuhlela nge Magic Wand. Isibhakabhaka cishe siphezulu esiphelele, futhi thina, ngosizo luka "Ukubekezela", singayikhetha ngokuphelele.
Ngokuhamba kwesikhathi (ukuzuza okuhlangenwe nakho) uzoqonda ukuthi yiziphi izithombe ithuluzi elingasetshenziswa.
Siyaqhubeka nomkhuba.
Dala ikhophi yocingo ngesinqamuleli somthombo I-CTRL + J.
Bese uthatha "I-wand wand" futhi usethe kanje: "Ukubekezela" - 32, "Ukumangalisa" futhi "Amaphikseli aseduze" kufakiwe, "Isibonelo esivela kuzo zonke izendlalelo" ukhutshaziwe.
Khona-ke, ekubeni ungqimba ngekhophi, chofoza phezulu esibhakabhakeni. Sithola okulandelayo:
Njengoba ubona, isibhakabhaka asikwabiwe ngokugcwele. Yini okufanele uyenze?
"I-wand wand"njenganoma iyiphi ithuluzi lokukhetha, linomsebenzi owodwa ofihliwe. Kungabizwa ngokuthi "engeza endaweni ekhethiwe". Umsebenzi usebenze ngenkathi ukhiye uphansi SHIFT.
Ngakho, siyaziphoqa SHIFT bese uchofoze engxenyeni engabonakali ebhakabhakeni.
Susa ukhiye olungadingekile DEL bese ususa ukukhethwa ngenkinobho yokushothikhathi. I-CTRL + D.
Ihlala nje ukuthola isithombe sesibhakabhaka esisha bese uyibeka phakathi kwezingxenye ezimbili kule palette.
Kule thuluzi lokutadisha "I-wand wand" kungabhekwa njengokuphelele.
Hlaziya isithombe ngaphambi kokusebenzisa ithuluzi, sebenzisa izilungiselelo ngokuhlakanipha, futhi ngeke ungene ezinkambeni zalabo abasebenzisi abathi "I-wand eyingozi". Ziyiziqhamuka futhi aziqondi ukuthi wonke amathuluzi we-Photoshop asebenza ngokulinganayo. Udinga nje ukwazi ukuthi uzowasebenzisa nini.
Inhlanhla emsebenzini wakho nohlelo lwe-Photoshop!
