Funda indlela yokulungisa i-Distortion ye-Lens evamile
Ukuphazamiseka kwePincushion ngenye yeengxaki ezincinci zekhamera ezinokuthi zenzeke kwaye zenze imiphumo engathandekiyo kwimifanekiso yakho. Nangona kunjalo, kulula ukulungisa okanye ukunciphisa xa uyazi ukuba ukhangele ntoni kwaye kutheni kwenzeka.
Yintoni iPincushion Distortion?
Ukuphazamiseka kwePincushion yiphumo lentsholongwane elibangela ukuba imifanekiso ifakwe kwiphakathi. Cinga nje ngefuthe kwi-pincushion njengepini ephoswe kuyo: isalathisi ejikeleze ipini iyahamba iphantsi kwiphonji njengoko kusetshenziswe uxinzelelo.
Enye indlela yokujonga ukuphazamiseka kwe-pincushion kukujonga i-piece of paper grid. Pushisa kwinqanaba lephepha kwaye uqaphele ukuba imigca eqondileyo yegridi iyaqala ukujika ngaphakathi ngaphakathi kwi-indentation. Ukuba ufufake isakhiwo esinde kunye nemigca eqondekileyo, ukuphambana kwe-pincushion ye-lens kuya kuba nomphumo ofanayo.
Ukuphazamiseka kwePincushion kudla ngokudibanisa kunye ne- telephoto lens , kwaye ngokukodwa, ukucoca i-telephotos. Ukuphazamiseka kuya kufuthi kuvele kwiphepha le-telephoto ye-lens. Impembelelo ye-pincushion iyanda kunye nomgama into evela kwi-axis optical ye-lens.
Ingumphumo ochaseneyo wokugqithisa lensalense kwaye, njengowomlingani wayo, ukuphazamiseka kwe-pincushion kubonakala kakhulu kwimifanekiso eneendlela ezichanekileyo (ingakumbi xa imigca isondele kumda womfanekiso).
Ukulungiswa kwePincushion Distortion
Ukuphazamiseka kwePincushion kunokulungiswa lula kwiinkqubo zemihla yokuhlela umfanekiso ezifana ne-Adobe Photoshop, equlethe i-"lens distortion". Iiprogram zokuhlela izithombe zamahhala nazo zinikeza izilungiso ezingekho ngaphantsi.
Njengokuphazamiseka komgqomo, ukuphazamiseka kwe-pincushion kuphakanyiswa yimiphumo yembono kwimifanekiso . Oku kuthetha ukuba ezinye zezi mpazamo zingalungiswa kwikhamera.
Ngexesha lokutshulwa, ungathatha amanyathelo ambalwa ukuphelisa okanye ukunciphisa ukuphazamiseka kwepincushion:
- Ngenxa yokuba ukuphazamiseka kwe-pincushion kudla ngokuchaphazela izinto ezineendlela ezichanekileyo, unokunciphisa umphumo wokuphambukisa kwe-pincushion ngokudubula izinto ezingenayo imigca eqondileyo. (Akunakwenzeka njalo, kunene?)
- Zama ukuphepha ukutshitshiswa ekuphakameni okukhulu kwe-lens ye-zoom lens. Hambisa kufuphi nesihloko kwaye usondeza xa kunokwenzeka okanye ukudubula umfanekiso obanzi kunokuba ungathanda nokutshala kwikhompyutha.
- Hambisa kwindawo eyahlukileyo kwaye ubone ukuba indlela eyahlukileyo yento iyanciphisa umphumo we-pincushion. Ungaphinda ufune ukutshintsha ingcamango ngokupheleleyo kwaye ugweme ukuyifotola into ngokuchanekileyo ukwenzela ukuba ukuphazamiseka kube yinto entle kwimifanekiso ye-aesthetics. (Xa awukwazi ukuyilungisa, phucula!)
- Ukuba unemizila eqondileyo kwinto yakho, zama ukuwagcina esondele kwiphakathi yesakhelo ngokunokwenzeka. Imigca ecaleni kwecala lokwakheka liza kubonakala lichithwa ngakumbi ngenxa yokuba isakhelo simgca ngokuthe ngqo.
