Yongeza iDrama kwiiMifanekiso Zakho eziLuhlu oluBalulekileyo
Ngelixa ezininzi izihlungi zefilimu zakudala ziye zingasebenzi kwihlabathi lezithombe zedijithali, ezimbalwa zihlala zinceda kakhulu. Enye yezi zihlunu ze-polarizer.
I-polarizer isetyhula ingasetyenziselwa ukongeza imiphumo emangalisayo kwiifoto zakho kwaye enye yeendlela zobuchwephesha abazisebenzisayo bathembela ekudaleni imifanekiso enemifanekiso enemibala ecebileyo kunye nokuqhathaniswa okukhulu. Nangona kunjalo, kufuneka ukwazi ukuwusebenzisa ukuze uphumelele kuyo!
Yintoni i-Polarizer?
Ngokucacileyo, i-polarizer iyanciphisa umlinganiselo wokukhanya oboniswayo oya kwikhono lakho lekhamera. Yindlela yokunqumla ukukhanya okungenamsoco kunye nomsindo wemoya kwaye ivumela ikhamera ukuba ibambe umfanekiso ocacileyo, ococekileyo.
Ukuba unezibuko zokukhanya ezigqobileyo ngosuku lokushisa ilanga, ngoko ubonile ukuba i-polarizers iyakwenza ntoni. Ngomlenze ococekileyo, isibhakabhaka esibhakabhaka sibonakala sibe luhlaza okwesibhakabhaka kwaye amafu abonakala ephuma kwimvelaphi. Naluphi na ukubonakalisa kwamanzi kususwa kwaye ungazibona unzulu kunokuba unakho ngaphandle kweziglasi zakho. Isihlungi sokucoca sinokuthi sibe nomphumo ofanayo kwikhamera.
Indlela yokusebenzisa i-Filter Polarising
Ukusetyenziswa kwamatye kusebenza kakhulu kwi-degrees ezingama-90 ukuya kwelanga (okanye umthombo wokukhanya). Ukugqithisa okuphezulu kuza kwenzeka xa isihloko sakho sisekunene kwelanga. Kwii-degrees ezingama-180 (xa ilanga lingasemva kwakho) ukuhlanjululwa komzimba kungekho. Phakathi kwezi ngongoma zimbini, umlinganiselo wobugqwetha uyahluka.
Isihlungi se-circular polarizing sehla phambi kwekhamera yekhamera kwaye inezikhonkwane ezimbini ezijikelezayo. Ukusebenzisa i-polarizer, vele udibanise i ring yangaphambili ukuze usebenze i-polarization.
Khangela ngaphakathi kwekhamera ngelixa uphendulela isihlungi. Uya kukwazi ukuba uphumelele ukuhlengahlengiswa ngenxa yokuba ukucinga kuya kutshabalala kwaye ukungafani phakathi kwezulu esibhakabhaka namafu kuya kwanda.
Ziqhelanise kunye nezibonakaliso kunye nesibhakabhaka esibhakabhakeni ngelixa usetyenzisiweyo kwisihlunu esikhombisayo. Thatha iifoto zengcamango efanayo kumgangatho ogqithiseleyo kwaye ngaphandle kokugqithisa kunye nokuthelekisa ezimbini. Ukwahlukana kufuneka kube mkhulu.
Emva kokuba uqaphele ngemiphumo yohlengahlengiso uya kufumana uluncedo nangona kungekho bhakabhaka okanye umfanekiso kumfanekiso. Le yimizekelo emihle kakhulu esetyenzisiweyo ukuchaza imiphumo yokumisa. Uninzi lwabafaki beefoto abanobugcisa abanqabile ukuba bathathe i-polarizer ngaphandle kweelensi zabo, oko kukubaluleka kwesi sihluzi.
Iimpawu ezenziweyo zeFilda eLawulayo
Ukhumbule ukuba ukusebenzisa isihlunu esilulayo kuya kunciphisa umlinganiselo wokukhanya ukufikelela kwintsimbi yekhamera ngamanqanaba amabini okanye amathathu- f-stops , ngoko kuya kufuneka ulungelelanise oku. Khetha isivinini se-shutter esicothayo (kwaye usebenzise i- tripod xa kuyimfuneko), uvule ngokukhetha kwi-f f / ukuyeka, okanye ukongeza ukukhanya kwimeko (kwinqanaba elifanayo, ukuba kunokwenzeka).
Izimo zokukhanya eziphantsi azilungele ukusebenzisa isihlunu esikhombisayo. Ukuba udinga ukusika umva kwimini okanye ufuna ukukhulisa amafu ekushoneni kwelanga, sebenzisa i-tripod.
Kungcono ukubeka ingqwalaselo yakho uze ufumane ingongoma yokugqithisa. Oku kungenxa yokuba isangqa langaphambili le-lens elifakwe kwi-polarizer liyakwazi ukujikeleza ngelixa ligxininisa kwaye lilahla ukuhlanjululwa. Nangona kufuneka uphinde ulungele emva kokucoca, uluhlu lwefayile kufuneka lube lulungelelaniso oluqhelekileyo olushiye lona (ngaphandle kokuba utshintshe iigxininiso).
Ukuthenga i-Filter Polarising
Izifayile ezicwangcisayo azihlambulukanga kwaye kubalulekile ukugcina umgangatho wengqondo xa uthengela enye. Khumbula ukuba iifoto ezibalaseleyo ziveliswa ngileyo, ikhwalithi yekhwalithi kunye nokugqithiswa okufanayo kwifayili ye-lens yakho kufuneka ifake kwisihlunu sakho sokucoca.
Musa ukuthenga i-polarator linear ukusebenzisa i-DSLR. Ezi zisetyenziselwa ukugxilwa kwekhamera zekhamera zefilimu kwaye, ngelixa zikwazi ukukhanya ngokugqithiseleyo ngaphezu kwe-polarizer setyhula, zingonakalisa ikhompyutha yakho yekhamera.
Iiprolarizers zeSetyhula zaphuhliswa xa iikhamera zefilimu zaqala ukusebenzisa ii-autofocus lens kunye ne-electronics complex. Ukuba icebo litshoyo lithetha kuphela 'i-polarizer' kuyo, ngoko li-polarizer. I-polarizers yeSetyhula iza kuhlala isithi 'i-polarizer yetyhula.' Oku kubaluleke kakhulu ukukhangela xa usesha ngeebhondi zeempahla zeekhamera!
Ukuba unayo iilensi ezininzi kunye nobukhulu befayile ezihlukileyo oza kukwazi ukuhamba kunye nesihlunu esisodwa. Ngethuba nje umahluko wobukhulu befayile ehlukileyo, ungathengi i-step-up okanye ye-down-down ring. Ezi zi-adapters ezingabizi zizahluka ngobukhulu kwaye zingasetyenziselwa ukulingana, umzekelo, isihlungi se-58mm kwi-lens ethatha ama-52mm.
