Funda indlela yokulungisa ukuhlukaniswa kweLenphoto Lens Distortion
Ukuphazamiseka kwe-Pincushion kungenye yezinkinga ezincane zekhamera ezingenzeka futhi zenze imiphumela engathandeki ezithombeni zakho. Noma kunjalo, kulula ukulungisa noma ukunciphisa uma wazi ukuthi ungabheka nokuthi kungani kwenzeka.
Kuyini ukuphazamiseka kwe-Pincushion?
Ukuphazamiseka kwe-Pincushion kuwumphumela we-lens obangela izithombe ukuthi zikhonjiwe phakathi. Cabanga nje ngokuthi umphumela owenziwe nge-pincushion njengephini iphoqelelwe kuwo: indwangu ezungeze iphini iyahamba phansi iphinde iphinde iphinde ingcindezi isetshenziswa.
Enye indlela yokubona ukuphazamiseka kwe-pincushion ukubuka ucezu lwephepha legridi. Pushisa maphakathi nephepha bese uqaphela ukuthi imigqa eqondile yegridi iqala ukujika ngaphakathi ekubhekisweni kokungena. Uma ubuka isakhiwo esinde kakhulu ngemigqa eqondile, ukuphazamiseka kwe-pincushion kwe-lens kuzoba nomphumela ofanayo.
Ukuphazamiseka kwe-Pincushion kuvame ukuhlotshaniswa ne- telephoto lens , futhi ikakhulukazi, ukusondeza i-telephotos. Ukuphazamiseka kuvame ukuvela ekupheleni kwe-telephoto ye-lens. Umphumela wokuphazamisa we-pincushion ukwandisa ngebanga le nto ivela e-optical axis ye-lens.
Kungumphumela obhekene nokuhlanekezela kwamalensi lensimbi futhi, njengokufana nomlingani wayo, ukuphazamiseka kwe-pincushion kubonakala kakhulu ezithombeni ezinemigqa eqondile (ikakhulukazi lapho imigqa iseduze komkhawulo wesithombe).
Ukulungisa ukuphazamiseka kwe-Pincushion
Ukuphazamiseka kwe-Pincushion kungalungiswa kalula ezinhlelweni zesimanje zokuhlela isithombe ezifana ne-Adobe Photoshop, equkethe isilungisi sokulungisa ukuphazamiseka kwamalensi. Izinhlelo zokuhlela izithombe zamahhala nazo zinikeza izilungiso ezincane kancane eziyinkimbinkimbi.
Njengokuphazamiseka komgqomo, ukuphazamiseka kwe-pincushion kukhuliswa ngemiphumela yombono ezithombeni . Lokhu kusho ukuthi ezinye zalezi ziphazamiso zingalungiswa kwikhamera.
Ngesikhathi ukudubula, ungathatha izinyathelo ezimbalwa ukuqeda noma ukunciphisa ukuphazamiseka kwe-pincushion:
- Ngoba ukuphazamiseka kwe-pincushion kuvame ukuthinta izinto ezinemigqa eqondile, unganciphisa umphumela wokuphazamiseka kwe-pincushion ngokudubula izinto ezingenayo imigqa eqondile. (Akunakwenzeka njalo, akunjalo?)
- Zama ukugwema ukudubula ekukhuliseni okukhulu kwe-lens zoom lens. Hamba eduze nendaba bese usondeza uma kungenzeka noma udonsa isithombe ngokubanzi kunalokho ongakuthandayo nokutshala kukhompyutha.
- Hambisa endaweni ehlukile bese ubona uma umbono ohlukile wezinto kunciphisa umphumela we-pincushion. Ungase futhi ufune ukushintsha umbono ngokuphelele futhi ugweme ukuthwebula isithombe ngokuqondile ukuze ukuphazamiseka kube isici esihle ku-aesthetics yesithombe. (Uma ungakwazi ukulungisa, phuthukisa!)
- Uma unemigqa eqondile entweni yakho, zama ukuwagcina eseduze nendawo yefreyimu ngangokunokwenzeka. Imigqa eceleni komkhawulo wefreyimu izobonakala ihamba kakhulu ngoba uhlaka luwumugqa oqondile.
