Engeza iDrama kuya ezithombeni zakho ezine-Filter ebalulekile
Nakuba izihlungi zamafilimu ezindala zasesikoleni manje zingasebenzi emsebenzini wezithombe zedijithali, ezimbalwa zihlala ziwusizo kakhulu. Enye yalezi ziyisihlungi se-polarizer esiyindilinga.
I-polarizer eyisiyingi ingasetshenziselwa ukwengeza imiphumela ephawulekayo ezithombeni zakho futhi ingenye yezindlela abadwebi bezithombe abazisebenzisayo bathembele ekudaleni izithombe ezinemifanekiso enemibala ecebile nokuphambene okunamandla. Noma kunjalo, udinga ukwazi ukuthi ungayisebenzisa kanjani ukuze uthole okuhle kakhulu kuwo!
Iyini i-Polarizer?
Ngokumane nje, i-polarizer inciphisa inani lokukhanya okuboniswayo okuya kwisitho sesithombe sekhamera yakho. Iyindlela yokunqamula ukukhanya okungenamsoco nomswakama womkhathi futhi ivumela ikhamera ukuthi ithathe isithombe esicacile, esicacile.
Uma unezibuko zokugcoba ezigqoke kakhulu ngosuku olusenyakatho echibini, khona-ke usubonile ukuthi yiziphi izinhlayiya ezikwazi ukuzenza. Ngensiza ekhangayo, isibhakabhaka esibhakabhaka sibonakala sibuluhlaza okwesibhakabhaka futhi amafu abonakala ephuma ngemuva. Noma yikuphi ukucabangela kwamanzi kususwe futhi ungabona okujule kunakho konke ngaphandle kwezibuko zakho. Isihlungi esikhombisayo singaba nomphumela ofanayo ekhamera.
Indlela Yokusebenzisa Isihlungi Esibucayi
I-polarization iphumelela kangcono emazingeni angu-90 elangeni (noma umthombo wokukhanya). Ukumiswa okuphezulu kuyokwenzeka uma isihloko sakho sisekugcineni ngakwesokudla. Ngama-degrees angu-180 (lapho ilanga likulandela) ukuhoxiswa kuyobe kungekho. Phakathi kwala maphuzu amabili, inani lobunikazi lizohluka.
Isihlungi se-polarizing esiyindilinga sishaya phambili kwekhamera yekhamera futhi sinamasondo amabili ajikelezayo. Ukuze usebenzise i-polarizer, vele ushintshe indandatho yangaphambili ukuze usebenze ukuhogela.
Bheka ngaphakathi ikhamera ngenkathi uvula isihlungi. Uzokwazi ukuthi uphumelele ekukhuliseni ngoba ukucabangela kuzonyamalalala futhi umehluko phakathi kwesibhakabhaka esibhakabhaka namafu kuzokwanda.
Hlanganisa ngemibonakude kanye nesibhakabhaka esibhakabhaka ngenkathi ujwayele ukuhlunga ukuhlunga. Thatha izithombe zesimo esifanayo ekugqaseni okuphezulu futhi ngaphandle kokumisa futhi uqhathanise lezi ezimbili. Umehluko kufanele kube okuphawulekayo.
Uma usuqaphela imiphumela ye-polarization uzothola usizo lwawo ngisho nalapho kungekho isibhakabhaka noma ukucabangela esithombeni. Lezi yizibonelo ezimbili ezinhle kakhulu ezisetshenziselwa ukuchaza imiphumela yokwehlisa umzimba. Abathwebuli bezithombe abaningi abanamakhono abatholakali ukukhipha i-polarizer ngaphandle kwamalensi abo, ukuthi yikuphi okuwusizo lesi sihlungi.
I-Drawbacks yeFripper Filter
Khumbula ukuthi ukusebenzisa isihlungi sokuhlunga kuyokwenza ukunciphisa inani lokukhanya lifinyelele inzwa yekhamera ngamanqamu amabili noma amathathu, ngakho-ke kuzodingeka ulungiselele lokhu. Khetha isivinini se-shutter esincane (bese usebenzisa i- tripod uma kudingeka), vula ngokukhetha i-f / stop engezansi, noma wengeze ukukhanya okungaphezulu endaweni (ekhoneni elifanayo, uma kungenzeka).
Izimo zokukhanya eziphansi azilungile ukusebenzisa isihlungi sokuhlunga. Uma udinga ukucubungula ekupheleni kosuku noma ufuna ukukhulisa amafu ekushoneni kwelanga, sebenzisa i-tripod.
Kungcono ukubeka ukugxila kwakho bese uthola iphuzu lokumiswa okuphezulu. Lokhu kungenxa yokuthi indandatho yangaphambili yelensi lapho i-polarizer ifakwe kuyo ingashintsha ngenkathi igxila futhi ilahla ukuhlonza. Ngisho noma kufanele uphinde uphinde usebenze ngokweqile, umcibisholo kufanele uqhubeke nokulungiswa okujwayelekile owashiye (ngaphandle uma ushintsha amaphuzu okugxila).
Ukuthenga i-Filter Ebucayi
Izihlungi ezitholayo azizishibhile futhi zibalulekile ukugcina ikhwalithi engqondweni uma uthengisa owodwa. Khumbula ukuthi izithombe ezibukhali kakhulu zikhiqizwa ngekhwalithi enhle, ikhwalithi kanye nokulingana okufanayo okufaka kukhwalithi ye-optical ye-lens yakho kufanele ingene kusihlungi sakho sokuhlunga.
Ungathengi i-polarizer ehambisanayo ukusebenzisa ne-DSLR. Lezi zisetshenziselwa ukugxila kumakhamera wefilimu okugxilwe kuyo futhi, ngenkathi zingabonakalisa ukukhanya okukhulu ngaphezu kwe-polarizer yesiyingi, zingalimaza i-electronics yekhamera yakho.
Ama-polarizers ayindilinga athuthukiswa lapho amakhamera efilimu aqala ukusebenzisa ama- autofocus lens kanye ne-electronics eyinkimbinkimbi ngoba ama-polarizers ahlukile awasebenzanga nobuchwepheshe obusha. Uma isihlungi sisho nje ukuthi 'i-polarizer' kuso, khona-ke i-polarizer eqondile. Ama-polarizers ayindilinga azothi njalo 'i-polarizer yesikhala.' Lokhu kubaluleke kakhulu ukubheka lapho usesha ngezinsimbi zezinkampani ezisebenzayo!
Uma unama-lens amaningi anezilinganiso ezihlukahlukene zezihlungi ungase ukwazi ukuhamba nesihlungi esisodwa se-polarizing. Uma nje umehluko wezinkinobho zokuhlunga akusizi kakhulu, uthenge indandatho-isinyathelo noma i-step-down ring. Lezi adaptha ezingabizi ziza ngobukhulu obuhlukahlukene futhi zingasetshenziselwa ukulingana, isibonelo, isihlungi se-58mm ku-lens esithatha izihlungi ezingu-52mm.
