4.Uyilo lwezakhiwo kunyeingaphakathipi-hotography
Ukufota ngobugcisa bokwakha kuphawulwa ngokufuna kwayo imigca ethe tye yobugcisa bokwakha, ubungakanani obuchanekileyo, kunye neenkcukacha ezicacileyo kumfanekiso wonke. Ukukhanya kunokuba yinto yendalo okanye eyenziweyo, kwaye kulula ukuba kubekho iimpazamo ezifana nokugqwetheka, ukugoba kwentsimi, ukuphazamiseka kwe-chromatic, kunye ne-astigmatism.
Iilensi ze-Tilt-shift zezona zikhethwayo xa kufotwa ngezakhiwo. Zingalungisa ngokupheleleyo ukuphambuka kwembono kunye nokuphambuka kwe-barrel/pincushion ngokuyitshintsha okanye ukuyijika i-optical axis, ngelixa zisusa ukugoba kwentsimi, ziqinisekisa ukuba umbindi kunye nemiphetho yomfanekiso zibukhali ngokulinganayo, ngaloo ndlela ziphepha ukuphazamiseka okuphakathi ukusuka kwi-optical view.
Ukusebenzisa isixhobo esibizwa ngokuba yi-ultra-ilensi enekona ebanziiyakwazi ukubamba indawo, kodwa inokuba nefuthe elibi kwimibhobho. Xa ufota ngelensi ebanzi, kuyacetyiswa ukuba umise i-aperture ukuya kwi-F8-F11 ukuze ucinezele ukugoba kwentsimi kunye nokuguquguquka kwe-chromatic.
Xa ufota izakhiwo usuka ngaphantsi okanye ngaphezulu, zama ukugcina ikhamera ikwinqanaba elifanayo nemigca yesakhiwo ukuze unciphise ukugqwetheka kombono. Ukuba akunakwenzeka ukugcina inqanaba lekhamera, izixhobo zokulungisa umbono zingasetyenziswa emva kokucubungula.
Xa ubhala imifanekiso yezakhiwo, qiniseka ukuba imigca ephambili yesakhiwo (njengeendonga kunye neefreyimu zeefestile) ihambelana nomda wefreyimu ukuze kuthintelwe ukuba imigca ivele emaphethelweni omfanekiso.
Sebenzisa ukukhanya okuthambileyo kwifoto yezakhiwo zangaphakathi ukunciphisa i-astigmatism ebangelwa kukukhanya okuphantsi, ngelixa unciphisa umahluko ophezulu weglasi/isinyithi kunye nokuthintela ukuphambuka kwe-chromatic. Kwifoto yezakhiwo zangaphandle, faka i-lens hood ukuze uphephe ukukhanya kunye nokwandiswa kokuphambuka okubangelwa kukukhanya okunamandla okukhanya ngqo kwilensi.

5.Izilwanyana zasendle kunyesamazibukopi-hotography
Ukufota izilwanyana zasendle kunye nemidlalo kusetyenziswa kakhulu iilensi ze-telephoto. Ezi ndawo zibonakaliswa kukuhamba ngesantya esiphezulu komntu ochaphazelekayo, okufuna ukulandelelwa ngokukhawuleza kokugxila, kwaye ukukhanya kunokuba namandla okanye kube buthathaka. Iingxaki eziqhelekileyo zokungaphambuki ziquka i-coma, i-astigmatism, i-chromatic aberration, kunye ne-spherical aberration.
Xa uthatha imifanekiso yezilwanyana zasendle/ezemidlalo, beka phambili izinto ezibalulekileyoiilensi zefowuningezinto ezisasazekileyo ukuze kuthintelwe ngempumelelo ukuphambuka kwe-chromatic. Xa kukhanya ngaphandle ngamandla, ukumisa i-aperture ngokuma oku-1-2, umzekelo, ukusuka kwi-F2.8 ukuya kwi-F4, kunokuphucula kakhulu ukuqaqamba kombindi kunye nemiphetho, kuthintele i-coma kunye ne-astigmatism, kwaye kuphucule ukuchaneka kwe-autofocus.
Xa uthatha imifanekiso yemidlalo ekukhanyeni okuphantsi kwaye ufuna imbobo enkulu, khetha imbobo yesibini ngobukhulu yelensi (efana ne-F2.8). Ukuba kukho i-coma, yima uye kwi-F3.5 ukuze ulinganisele ukungenisa ukukhanya kunye nolawulo lokungaqondi. Ukusebenzisa imo yokulandelela ukugxila kwekhamera ngesantya esiphezulu kuqinisekisa ukuba ukugxila kuhlala kulowo ushukumayo, kunciphisa ukufiphala kwembobo okubangelwa ziingxaki ezingaphandle kwengqwalasela.
Ukongeza, ukusebenzisa isibambi seelensi zetelephoto + itripod/monopod kunokunciphisa ukushukuma kweelensi kwaye kuthintele i-astigmatism ebangelwa kukushukuma; ukufaka i-lens hood kunokuthintela ukukhanya kwelanga ngqo ekubetheni ilensi xa udubula ngaphandle, kunciphisa ukukhanya kunye nokuphazamiseka; xa udubula iintaka ezibhabhayo/ezihamba ngesantya esiphezulu, zama ukuzalisa indawo esembindini yesakhelo ngento eshukumayo ukuze unciphise impembelelo yokushukuma komphetho.
Ukuqukumbela, ukuze uphephe iingxaki zokungahambelani kwelensi, kufuneka uqale uqonde ilensi oyisebenzisayo. Ilensi nganye inoluhlu oluphezulu lokusebenza. Vavanya ilensi yakho kwangaphambili ukuze ubone ubude okanye i-aperture apho ukungahambelani kubonakalayo khona, kwaye uziphephe ngenkuthalo ngexesha lokudubula.
Kubalulekile ukuqaphela ukuba ukulungiswa kwe-optical of aberrations (ukukhethwa kwelensi, ukuyeka ukuvuleka kwe-aperture, ukulungiswa kwe-optical axis) kubalulekile, ngelixa imbuyekezo emva kokucubungula iyongeza kuphela; ukucubungula kakhulu emva kokucubungula kuya kubangela ukulahleka kweenkcukacha zomfanekiso.
