I-magic wand - elinye lamathuluzi "ahlakaniphile" ohlelweni lwe-Photoshop. Umgomo wokusebenza ukukhetha amaphikseli wethoni noma umbala othile esithombeni.
Imvamisa, abasebenzisi abangaqondi amandla nezilungiselelo zethuluzi bayadumala ekusebenzeni kwalo. Lokhu kungenxa yokwenzeka okungenakubonakala kokulawula ukwabiwa kwethoni ethile noma umbala.
Lesi sifundo sizogxila ekusebenzeni naso I-magic wand. Sizofunda ukuthi sizibona kanjani izithombe esisebenzisa kuzo ithuluzi, futhi sizenze ngendlela oyifisayo.
Uma usebenzisa i-Photoshop CS2 noma ngaphambili, I-magic wand Ungayikhetha ngokuchofoza okulula kusithonjana sayo kuphaneli kwesokudla. I-CS3 ingenisa ithuluzi elisha elibizwa Ukukhetha Okusheshayo. Leli thuluzi libekwa engxenyeni efanayo futhi ngokuzenzakalelayo yilo eliboniswa kubha yamathuluzi.
Uma usebenzisa inguqulo ye-Photoshop ephakeme kune-CS3, kuzodingeka uchofoze isithonjana Ukukhetha Okusheshayo futhi uthole ohlwini olwehliswayo I-magic wand.
Okokuqala, ake sibheke isibonelo somsebenzi. I-magic wand.
Ake sithi sinesithombe esinjalo sangemuva gradient nomugqa oqinile oledlule:
Ithuluzi elilayisha endaweni ekhethiwe lawo ma-pixel athi, ngokusho kwe-Photoshop, abe nethoni efanayo (umbala).
Uhlelo lunquma amanani wedijithali imibala bese ukhetha indawo ehambelana nayo. Uma uzungu lukhulu impela futhi lunokugcwaliswa okumbumbulu, khona-ke kuleli cala I-magic wand ayinakubekelwa indawo.
Isibonelo, sidinga ukugqamisa indawo eluhlaza okwesibhakabhaka esithombeni sethu. Konke okudingekayo nje chofoza inkinobho yegundane kwesobunxele kunoma iyiphi indawo yomucu oluhlaza okwesibhakabhaka. Uhlelo luzobona ngokuzenzakalelayo inani le-hue bese lilayisha amaphikseli ahambelana nalelo nani endaweni ekhethiwe.
Izilungiselelo
Ukubekezelela
Isenzo sangaphambilini besilula, ngombana indawo leyo ibigcwele ukugcwala, okutsho ukuthi, azikho ezinye izithunzi eziluhlaza okotshani. Kwenzekani uma usebenzisa ithuluzi ku-gradient ngemuva?
Chofoza endaweni empunga ku-gradient.
Kulokhu, uhlelo luqokomise uhla lwama-shades asondele ngenani nombala onsomi endaweni esichofoze kuyo. Leli banga linqunywa izilungiselelo zamathuluzi, ikakhulukazi, "Ukubekezelela". Isilungiselelo sise kubha yamathuluzi ephezulu.
Le pharamitha inquma ukuthi amasampula amangaki (iphuzu esichofoze kulo) angahluka emthunzini ozolayishwa (uqokonyisiwe).
Kithi, inani "Ukubekezelela" isethwe ku-20. Lokhu kusho ukuthi I-magic wand Faka ekukhetheni kwama-shades angama-20 amnyama futhi akhanyayo kunesampula.
I-gradient emfanekisweni wethu ifaka phakathi amazinga wokukhanya angama-256 phakathi komnyama nomhlophe ngokuphelele. Ithuluzi elikhethiwe, ngokuya ngezilungiselelo, amazinga angama-20 wokukhanya kuzo zombili izinkomba.
Ake, ngenhloso yokuhlola, sizame ukwandisa ukubekezelelana, sithi, kuye ku-100, siphinde sisebenzise I-magic wand kwi-gradient.
At "Ukubekezelela", ikhuliswe amahlandla ayisihlanu (ngokuqhathanisa neyangaphambili), insimbi yakhetha isigaba ezikhudlwana amahlandla ayisihlanu, ngoba akuzange kufakwe imithunzi engama-20 kunani lesampula, kodwa libe li-100 ohlangothini ngalunye lwesilinganiso sokukhanya.
Uma kudingekile ukukhetha kuphela umthunzi ohambelana nesampula, khona-ke inani le- "Tolerance" lisethelwe ku-0, elizokwazisa uhlelo ukuthi lungangezi ezinye izithunzi ekukhetheni.
Uma inani lokubekezelela lingu-0, sithola kuphela umugqa wokukhetha omncane oqukethe i-hue eyodwa ehambelana nesampula ethathwe esithombeni.
Amanani "Ukubekezelela" ingasetwa ebangeni kusuka ku-0 kuye ku-255. Ngaphezulu kwaleli nani, indawo enkulu izogqamiswa. Inombolo 255, esethwe enkundleni, yenza ithuluzi likhethe sonke isithombe (ithoni).
Amaphikseli asondele
Lapho ubheka izilungiselelo "Ukubekezelela" umuntu angaqaphela ukungajwayelekile okuthile. Uma uqhafaza ku-gradient, uhlelo lukhetha amaphikseli kuphela endaweni egcwaliswe yi-gradient.
I-gradient endaweni engaphansi komucu yayingafakwanga ekukhetheni, yize izithunzi ezikuyo zifana ngokuphelele nendawo ephezulu.
Okunye ukubekwa kwamathuluzi kunesibopho kulokhu. I-magic wand futhi ubizwa Amaphikseli asondele. Uma amazinyo abekwe phambi kwepharamitha (ngokuzenzakalela), uhlelo luzokhetha kuphela lawo amaphikiseli achazwe "Ukubekezelela" kufanelekile ebangeni lokukhanya nokukhanya, kepha ngaphakathi kwendawo ebekiwe.
Amanye amaphikseli afanayo, noma ngabe athile afanelekile, kodwa ngaphandle kwendawo ekhethiwe, awazukuwela endaweni elayishiwe.
Kithina, lokhu kwenzeka. Onke amaphikiseli afanayo ngaphansi kwesithombe awanakwa.
Masenze olunye ucwaningo bese sisusa izibunu ngaphambili Amaphikseli asondele.
Manje chofoza engxenyeni efanayo (ephezulu) yegradient I-magic wand.
Njengoba ukwazi ukubona, uma Amaphikseli asondele ikhubazekile, bese wonke amaphikiseli asesithombeni ahambelana nenqubo "Ukubekezelela", kuzoqokonyiswa noma ngabe bahlukaniswe yisampula (etholakala kwenye ingxenye yesithombe).
Izinketho ezingeziwe
Izilungiselelo ezimbili zangaphambilini - "Ukubekezelela" futhi Amaphikseli asondele - ebaluleke kakhulu kuthuluzi I-magic wand. Noma kunjalo, kukhona ezinye, yize kungabalulekile kangako, kodwa futhi nezilungiselelo ezidingekayo.
Lapho ukhetha amaphikseli, ithuluzi lenza lokhu ngokulandela izinyathelo, lisebenzisa amaxande amancane, athinta ikhwalithi yokukhetha. Kuvela imiphetho eyindida, evame ukubizwa ngokuthi “ileli” kubantu abavamile.
Uma isiza esinojamo bejometri eyiyo (i-quadrangle) siqokonyiswa, khona-ke inkinga enjalo ingaqhamuka, kepha lapho kukhethwa izindawo ezingajwayelekile, "izitebhisi" azinakugwenywa.
Imiphetho ebushelelezi encane eyisisekelo izosiza Smoothing. Uma isethi ehambisanayo isethwe, i-Photoshop izosebenzisa ukufiphala okuncane ekukhetheni, okungacishe kuthinte ikhwalithi yokugcina yemiphetho.
Isilungiselelo esilandelayo sibizwa "Isampula evela kuzo zonke izingqimba".
Ngokuzenzakalelayo, iMagro Wand ithatha isampula le-hue ukugqamisa kuphela kusuka kusendlalelo esikhethwe njengamanje kwiphalethi, okungukuthi, okusebenzayo.
Uma uhlola ibhokisi eliseduze kwalokhu kulungiselelwa, uhlelo luzothatha isampula ngokuzenzakalela kuzo zonke izendlalelo ezisencwadini bese ulufaka ekukhetheni, oluqondiswa yi-Ukubekezelela.
Prakthiza
Ake sibheke ukusetshenziswa kwensiza okusebenzayo I-magic wand.
Sinomfanekiso wokuqala:
Manje sizothatha indawo yesibhakabhaka nesethu, equkethe amafu.
Ngizochaza ukuthi kungani ngithathe lesi sithombe. Futhi ngoba ilungele ukuhlelwa nayo I-magic wand. Isibhakabhaka sicishe silinganiselwe ngokuphelele, futhi nathi "Ukubekezelela", singayikhetha ngokuphelele.
Ngokuhamba kwesikhathi (ulwazi olutholwayo) uzoqonda ukuthi iziphi izithombe ithuluzi elingasetshenziswa kuzo.
Siyaqhubeka nalo mkhuba.
Dala ikhophi yesendlalelo somthombo ngesinqamuleli sekhibhodi I-CTRL + J.
Bese uthatha I-magic wand futhi ulungiselele ngokulandelayo: "Ukubekezelela" - 32, Smoothing futhi Amaphikseli asondele kufakiwe "Isampula evela kuzo zonke izingqimba" inqanyuliwe.
Ngemuva kwalokho, lapho ungqimba lwamakhophi, chofoza phezulu kwesibhakabhaka. Sithola lokhu kukhethwa:
Njengoba ubona, isibhakabhaka sasingabonakali ngokuphelele. Yini okufanele uyenze?
I-magic wand, njenganoma yiliphi ithuluzi lokukhetha, linomsebenzi owodwa ocashile. Kungabizwa ngokuthi "engeza ekukhetheni". Umsebenzi uyenziwa lapho ukhiye ucindezelwa I-Shift.
Ngakho-ke, sibambe I-Shift bese uchofoza indawo esele engakhethiwe yesibhakabhaka.
Susa ukhiye ongadingekile DEL futhi ususe ukukhetha ngesinqamuleli sekhibhodi I-CTRL + D.
Kuhlala kuphela ukuthola isithombe sesibhakabhaka esisha bese usibeka phakathi kwezendlalelo ezimbili kwiphalethi.
Kuleli thuluzi lokufunda I-magic wand kungabhekwa njengokuqediwe.
Hlaziya isithombe ngaphambi kokusebenzisa ithuluzi, sebenzisa izilungiselelo ngobuhlakani, futhi ngeke uwele ezinhlwini zalabo basebenzisi abathi "Wand okwesabisa." Bangama-ameshaurs futhi abaqondi ukuthi wonke amathuluzi e-Photoshop awusizo ngokulinganayo. Udinga ukwazi kuphela ukuthi uzisebenzisa nini.
Inhlanhla emsebenzini wakho ngohlelo lwe-Photoshop!
