1.Yintoni ilensi eguquguqukayo kancinci?

Yintoni ukugqwethwa? Ukugqwethwa ligama elisetyenziswa kakhulu kwimifanekiso yezithombe. Libhekisa kwinto eyenzekayo kwinkqubo yokufota ethi ngenxa yemida ekuyilweni nasekuvelisweni kwelensi okanye ikhamera, imilo kunye nobukhulu bezinto ezikumfanekiso zahlukile kwizinto zokwenyani.

Ingxaki yokugqwetheka kwemifanekiso ichaphazela kakhulu umgangatho kunye nenkangeleko kunye nokuvakala kwemifanekiso. Ukuze kusonjululwe le ngxaki, abantu baqala ukuvelisa nokusebenzisa iilensi eziphantsi kokugqwetheka.

Yintoni iilensi ephambukisayo ephantsiIlensi ephothiweyo kancinci yilensi ekhethekileyo yokufota kunye nemifanekiso ye-optical. Le lensi inokunciphisa okanye isuse ngempumelelo imiphumo yokuphothwa ngokusebenzisa uyilo oluchanekileyo lwe-optical kunye neenkqubo zokwenza, kunye nokusetyenziswa kwezixhobo zeglasi ezikhethekileyo kunye nokudibanisa ilensi.

Besebenzisa iilensi ezibonisa ukugqwetheka okuphantsi, abafoti kunye nabathwebuli beevidiyo banokufumana imifanekiso eyinyani, echanekileyo neyendalo xa bethwebula, ehambelana ngokubanzi nemilo kunye nobukhulu bezinto zokwenyani.

Umzobo wokuguqulwa kwelensi

2.Ziziphi iingenelo zeelensi eziphantsi kokuphazamiseka?

Ukongeza ekunciphiseni iingxaki zokugqwetheka, iilensi eziphantsi kokugqwetheka zikwanazo nezinye izibonelelo ezenza ukuba zisetyenziswe kakhulu kwiindawo ezininzi zokusetyenziswa, ezinje ngokufota ngoyilo lwezakhiwo, ukufota ngemveliso, uphando lwezenzululwazi, njl. Makhe sijonge ngokusondeleyo:

Ilensi ephambukayo inika umfanekiso ochanekileyo nochanekileyo

Iilensi ezingalunganga ngokubanzi zibonelela ngemifanekiso echanekileyo ngakumbi. Ngokunciphisa ukugqwetheka, imilo kunye nobungakanani bezinto ezikumfanekiso zigcinwa zichanekile, zibonelela ngemifanekiso ngeenkcukacha ezicacileyo kunye nemibala echanekileyo.

Kwiimeko zezicelo ezifuna imifanekiso esemgangathweni ophezulu, kubaluleke kakhulu ukuzisebenzisaiilensi eziphantsi kokugqwetheka, njengakwimifanekiso, ukuhlolwa kwemizi-mveliso, imifanekiso yezonyango, njl.

Ilensi ephambukayo iphucula ukuchaneka kokulinganisa

Kwimimandla efana nokulinganisa nokuhlola, ukugqwetheka kunokukhokelela kwiimpazamo, ngaloo ndlela kunciphisa ukuchaneka kokulinganisa. Ukusetyenziswa kweelensi eziphantsi kokugqwetheka kunokunciphisa kakhulu le mpazamo, kuphucule ukuchaneka kokulinganisa, kwaye kuqinisekise ukuchaneka nokuthembeka kweziphumo zokulinganisa.

Ilensi ephambukayo ephantsi

Ilensi ephazamisayo esezantsi iphucula ukucutshungulwa kwemifanekiso

Kwizicelo zokujonga kunye nokucubungula imifanekiso kwikhompyutha, ukuphazamiseka kuya kubangela ukuphazamiseka kwii-algorithms ezilandelayo kunye nokucubungula.iilensi eziphantsi kokugqwethekainokunciphisa ubunzima bokucubungula kwaye ilula ukucutshungulwa kwemifanekiso okulandelayo.

Iphantsi iilensi zokuphambuka ziphucula amava omsebenzisi

Iilensi ezibonisa ukugqwetheka okuphantsi azisetyenziswa kakhulu kwiinkalo zobungcali kuphela, kodwa zikwabonelela abasebenzisi ngokubanzi ngamava angcono okudubula. Ngokunciphisa ukugqwetheka, iifoto zenziwa zibe zezokwenene kwaye zendalo, okuvumela abantu ukuba barekhode ngcono kwaye bakhumbule amaxesha abalulekileyo.

Ukongeza, iilensi ezingalunganga kakhulu zinokunciphisa ukolulwa kunye nokuguqulwa komfanekiso, okuvumela ababukeli ukuba babone ngokuchanekileyo imo kunye nobukhulu bezinto ekujoliswe kuzo. Oku kubaluleke kakhulu kwiingcali kwiinkalo ezifana nophando lwesayensi kunye noyilo lwemizi-mveliso.

Ilensi ephambukayo esezantsi iqinisekisa umgangatho wokubonakala

Iilensi eziphantsi zokuphazamisekazisetyenziswa kakhulu kwizixhobo zokubonisa, ezinokugcina umgangatho wokubonisa umfanekiso kwaye zenze umfanekiso wokubonisa ucace kwaye uthe tyaba. Oku kuluncedo kakhulu kwiindawo ezinje ngamagumbi eenkomfa kunye neethiyetha zasekhaya ezifuna ukubonisa isikrini esikhulu.
