I isimame wekhamera: design, injongo

Futhi bezithombe amateur nezobuchwepheshe abasebenzisi amakhamera bajwayelene nobunzima eziphakamayo inqubo ukuqopha ngokuqondile izandla. Okokuqala, kukhona ithuba eliphezulu ukuthola umfanekiso esilufifi, futhi okwesibili, ngisho nalapho engekho okubeka obala turbidity imiphumela maningi amathuba ukuze esingu abukhali ngokwanele. Ukuphungula loko kusiza isimame wekhamera, okungaletha design ehlukene, kodwa umsebenzi owodwa - ukudala kwezimo ezifanele ngokomzimba ngoba nenkanuko edlulele uzimele.

aphoyintimenti isimame

Sebenzisa lobu buchwepheshe kufanele kube ezimweni lapho kukhona ingozi ukuhlanekezela ikhwalithi yesithombe ngenxa ezinyakazayo ongahlosile we kulandzelana nekuhlunga tinsita. sinjalo Optical ivala ezinyakazayo ikhamera engeli namazinga eliqhaqhazelayo ukuvimbela ukufiphala izithombe kancane ijubane yokucina. Kubalulekile ukuqonda ukuthi khona kulesi sici, ikhamera cishe akusho kuhilelani yokusebenza negative izici, ngakho-ke akudingekile ngokuqinisekile ngeke. Enye into ukuthi kwezinye izimo isimame wekhamera asisho londoloza isimo, futhi kwesinye isikhathi indawo tripod ezivamile. Nakuba ukuthola izithombe izinga okusezingeni eliphezulu, kuyancomeka ukuba sihlanganise izindlela ezahlukene ezibangela ukuzinza kanye nokunciphisa kulokolokoza imiphumela.

Ikhamera apharathasi isimame

Ukusebenza bendabuko njengoba sinjalo optical mojuli bafakwe lens iyunithi futhi imele iqoqo izingxenye sokusebenza. Ikakhulu, i-eziyinkimbinkimbi ezakhiwe ezithathekayo isici optical ngesimo lens, okungafaka phakathi optical lens uhlelo. Futhi isimame kuhlanganisa emincane Isivinini izinzwa, ukulungisa izilungiselelo zekhamera oscillations evumela uhlelo ukulungisa izici elikhulu we balancer. Elibalulekile ingxenye, okuyilona elisebenzayo futhi olunikezwa ekamelweni isimame, futhi kuyinto electromagnet. Nale workpiece ihamba isici optical esekelwe ukufundwa izinzwa eshiwo ngenhla. Ukuze ukubambisana yezingxenye ngazinye uhlelo chip wemfanelo kusukela umsebenzi walo ixhomeke izinga jikelele kanye isimame.

izinhlobo izinhlelo

High-level nabalawuli kuvame lahlukaniswa izinhlobo - VR uhlelo kusuka Nikon futhi IS amamojuli njengoba lakhiwa Canon ochwepheshe. Ngokuvamile, imiphumela yokugcina kokubili izinhlelo babe izinga efanayo - ikakhulukazi amehlo ongelutho. Isici esibalulekile salo lwalezi nhlelo ukuthi kungenzeka ukwenza ngcono ikhwalithi yokubandula ngokudubula ekukhanyeni ongaphakeme. osenyameni Radical lesi simiso kwaba Umqondo womkhosi ndzawonye kulwa vibration ngesandla isimame wekhamera, okuyinto ngokuyisisekelo inguqulo ergonomic ngaphezulu tripod. Ngokuvamile, lezi amadivaysi, ngokuthi Steadicam, wasebenzisa ukuhlomisa amakhamera, kodwa muva nje basuke uya eba abasebenzisi futhi amakhamera.

Enye mkhuba ohlelweni kuqiniswa elisetshenziswa SLR amakhamera-Sony futhi Olympus amafemu. Kulokhu, isimame wekhamera ayakhelwe ku lens, futhi base-matrix iyunithi. Izinzuzo izixazululo ezinjalo zihlanganisa kwedivayisi module cishe yonke lens, kusukela uhlelo akasakhulumi ne yokukhanya, agcwalisa unit main.

izindlela ezisebenza nge isimame

Njengomthetho, kukhona izindlela ezimbili eyaba ngazo ikhamera isebenze umsebenzi isimame - umsebenzi futhi okuqhubekayo. izinga Kuhle ihlinzeka imodi wokuqala olulodwa, njengoba ngokuhamba ukusetshenziswa kwaso, ikhamera, cishe ukukhuluma, "yiqhwa" kuze kube ngomzuzu anomlandu isithombe. Kodwa futhi ngesakhiwo operation okuqhubekayo kohlelo njengoba sinjalo kungenziwa walungisiswa, uma kudingeka ngokuhamba kwenzeka lesi sigameko sokudubula ashukumisayo esikhathini esifushane ukuze uthole izithombe ezimbalwa. Ukuze uthuthukise izinga ucwaningo enjalo, ukuncoma nje ukusebenzisa izisekeli wekhamera ngesimo esifanayo isimame ngesandla. The main ukulungiswa module Uyoqeda ngeziphambeko abalulekile futhi abukhali, ume kuzo ekuqaleni lincane. Kodwa ngisho nalokhu ukwesekwa, ancike ukudalwa high quality izithombe akudingekile.

Indlela yokwenza isimame ngezandla

Ngokwami nokuqhuba module ehlanganyele lens noma inzwa ikhamera cishe akunakwenzeka, kodwa kunengqondo ukuzama ukudala ubuchwepheshe steadicam efanayo. Eqinisweni, kufanele uthole isimame elula, emthwesa umphumela ikhamera Shake. Umsebenzi kuzodinga induku metal main, okuyinto tooling esinqunyiwe ukubamba ikhamera, amabombo, kanye aphethe indlela.

Ngakho, ngokuyisisekelo umklamo kuyoba ukunciphisa kunyakaza adluliselwa ezandleni ikhamera ngesikhathi ngokudubula. Isakhi esiyinhloko uhlelo kuzokwenza isisekelo, Damping kunyakaza. Kungenisa iqoqo izinsimbi, isisindo okungaba ezihlukahlukene, futhi uhlelo amabombo zigxilé izikhundla ikhamera Ukujikeleza isihlobo ukuba eksisi induku. Ukuze isimame okuzenzela sihlanganiswe ngesikhathi esifanele ngenxa miscalculation e isakhiwo eyinhloko, kufanele sinikele iziqobosho okunokwethenjelwa izingxenye zayo ngazinye. Ngoba kokubili intonga, izesekeli ezihlobene ngeke ngaphansi imithwalo esindayo, kungashiwo kungagcini ezivamile obandayo kubakaki. Ngaphezu kwalokho, kubalulekile ukuba anezele ukuklanywa izibambo ergonomic ziye ukuqopha phakathi eside ukukhathala nokugcinwa kungandisa amplitude oscillations.

Yeka ukuthi kuyinto isimame ikhamera

Steadicam elula imodeli angathengwa 1,5-2 ayizinkulungwane. Deda. Kungaba idivayisi enemisebenzi ukuthi kufanelekile cishe wonke amamodeli ikhamera. Esikhathini ingxenye intengo phakathi ukunikela ikhwalithi ephezulu kanye ergonomic design izindleko ayizinkulungwane 5. Kunengqondo sinake isimame eziyinkimbinkimbi wekhamera, okuyinto sizofaka-module ehlangene, ngesandla Damping imishini futhi phansi ibha. kits ezinjalo kakade ecishe ibe yizinkulungwane 10-15.

isiphetho

Kukhethwa isimame okuningi kuncike kule mibandela sokudubula. Uma kuziwa 'ensimini' izimo kanye ashukumisayo photoshoot format, ngaphandle module esakhelwe kuleli matrix noma lens ikhamera ongakwazi ukuzenza. Nokho, ekhaya noma studio imvelo kuzosiza nezinsiza Ingaphandle wekhamera ngesimo bar efanayo noma Steadicam. Sekuvele kukhona okuningi kuzoncika inhlangano ukuqopha. isikhathi lapho umshini ngaphandle ukulungiswa ligxile kuncike - futhi phezu ikhwalithi yesithombe sizothinta ukuchayeka. The eside kangakanani, ayanda amathuba ukuze uthole isithombe izinga, ngisho ngaphandle kokusebenzisa kuqiniswa izinhlelo.
