Susa isizinda esiluhlaza ku-Photoshop

Isizinda esiluhlaza noma "i-hromakey" sisetshenziselwa ukudubula esikhundleni sayo esilandelayo nanoma iyiphi enye. Isihluthulelo se-chroma singase sibe umbala ohlukile, njengabluhlaza okwesibhakabhaka, kodwa okhehlaza kukhethwe ngezizathu eziningana.

Yiqiniso, ukudubula esizinda esibuhlaza kwenziwa ngemuva kokubhala noma ukwakheka kokuqala.
Kulesi sifundo sizozama ukukhipha isithunzi esibuhlaza kusukela esithombeni ku-Photoshop.

Susa ingemuva eluhlaza

Kunezindlela ezimbalwa kakhulu zokususa ingemuva kusuka kwesifanothi. Iningi lazo lilonke.

Isifundo: Susa isizinda esimnyama ku-Photoshop

Kukhona indlela ehle kakhulu ngokususa i-chromakey. Kumele kucatshangwe ukuthi ngokudubula okunjalo kungathola amafomu amabi, ukusebenza okuzoba nzima kakhulu, futhi ngezinye izikhathi akunakwenzeka. Ukuze uthole isifundo, lesi sithombe sensizwa esendaweni eluhlaza sitholakala:

Siyaqhubeka nokususwa kwe-chromakey.

1. Okokuqala, udinga ukuhumusha isithombe sibe isikhala sombala. I-Lab. Ukuze wenze lokhu, iya kwimenyu "Imodi yesithombe" bese ukhetha into oyifunayo.

   

2. Okulandelayo, iya kuthebhu "Iziteshi" bese uchofoza esiteshini "a".

   

3. Manje sidinga ukwakha ikhophi yalesi siteshi. Kungenxa yakhe ukuthi sizosebenza. Sithatha isiteshi ngenkinobho yegundane lesokunxele bese uhudula esithombeni ngaphansi kwephalethi (bheka isithombe-skrini).

   

   Iphalethi yesiteshi ngemuva kokudala ikhophi kufanele ibukeke kanje:

   

4. Isinyathelo esilandelayo ukunikeza isiteshi esiphambene nesiteshi, okungukuthi, isizinda kumele senziwe ngokumnyama ngokuphelele nentombazane emhlophe. Lokhu kufinyelelwa ngokunye ukugcwalisa isiteshi ngombala omhlophe nomnyama.
   Cindezela inhlanganisela yokhiye SHIFT + F5bese iwindi lezilungiselelo zokugcwalisa zizovuleka. Lapha sidinga ukukhetha umbala omhlophe ohlwini lokudonsa bese ushintshe imodi yokuxhuma "Ukuhamba".

   

   Ngemuva kokucindezela inkinobho Ok sithola isithombe esilandelayo:

   

   Khona-ke siphinda izenzo ezifanayo, kodwa ngezimnyama.

   

   Umphumela wokugcwaliswa:

   

   Njengoba umphumela awutholakali, siphindaphinda sigcwalise, lesi sikhathi sisuka kumnyama. Qaphela: qala ukugcwalisa isiteshi ngombala bese umhlophe. Ezimweni eziningi, lokhu kwanele. Uma ngemuva kwalezi zenzo isibalo asizange sibe mhlophe ngokuphelele, futhi isizinda sisesimnyama, bese uphinda inqubo.

   

5. Isiteshi esizilungiselele, ngakho-ke udinga ukwakha ikhophi yesithombe sokuqala kumaparethi wekhalenda ngesinqamuleli sekhibhodi I-CTRL + J.

   

6. Buyela kuthebhu ngeziteshi futhi usebenzise ikhophi yesiteshi. a.

   

7. Gwema ukhiye CTRL bese uchofoza isithonjana sesiteshi, udale indawo ekhethiwe. Lokhu kukhetha kuzonquma umjikelezo wesitshalo.

   

8. Chofoza kusiteshi ngegama "Lab"kufaka phakathi umbala.

   

9. Yiya kumaphethini wekhalenda, kukhophi yesizinda, bese uqhafaza isithonjana semaski. Isizinda esiluhlaza sisuswa ngokushesha. Ukuze ubone lokhu, susa ukubonakala kusuka kwesendlalelo esingezansi.

   

Ukususwa kwe-Halo

Silahle isizinda esiluhlaza, kodwa hhayi ngempela. Uma usondeza, ungabona umngcele omncane omnyama, okuthiwa i-halo.

I-halo ayibonakali nakancane, kodwa uma imodeli ibekiwe ngemuva kwesizinda esisha, ingaphazamisa ukwakheka, futhi kuyadingeka ukuyiqeda.

1. Cupha imaski engqimba, gcina CTRL bese uchofoze kuwo, ulayishe indawo ekhethiwe.

2. Khetha noma iyiphi yamathuluzi eqembu. "Qinisekisa".

3. Ukuhlela ukukhetha kwethu, sebenzisa umsebenzi "Hlela i-Edge". Inkinobho ehambelanayo itholakala kuphaneli eliphezulu lemingcele.

4. Ewindini lomsebenzi, shintsha umkhawulo wokukhetha bese ubhebhezela "amakhredithi" wamaphikseli kancane. Sicela uqaphele ukuthi ukuze kube lula, imodi yokubuka isethiwe. "Emhlophe".

5. Hlela umkhiqizo "Isendlalelo esisha ne-mask layer" bese uchofoza Ok.

6. Uma ngemuva kokwenza lezi zenzo, ezinye izindawo zihlala ziluhlaza, zingasuswa ngesandla nge-brush emnyama, isebenza kumaski.

Enye indlela yokukhipha i-halo ichazwe ngokuningiliziwe esifundweni, isixhumanisi esinikezwe ekuqaleni kwesihloko.

Ngakho, siphumelele ngempumelelo isizinda esiluhlaza esithombeni. Nakuba le ndlela kunzima kakhulu, ibonisa ngokucacile isimiso sokusebenza neziteshi lapho ususa izingxenye ze-monochromatic zesithombe.
