Cine vs Photography Lens: Momwe mungasankhire lens yoyenera pavidiyo
Mutha kujambula ndi mandala wamba pa kamera yanu ya kanema kapena DSLR, koma ngati mukufuna kuwongolera, kuwongolera kapena kujambula zithunzi zenizeni, ingakhale nthawi yosiya mandala a "kit" ndikukulitsa zida zanu.
Nawa malangizo othandiza posankha disolo la kanema.
Mu positi iyi tikambirana:
Kodi mukufunadi mandala atsopano?
Ojambula amatha kutengeka kwambiri ndi zida za kamera ndikusonkhanitsa zida zamitundu yonse zomwe sazigwiritsa ntchito. Magalasi abwino samakupangitsani kukhala wojambula bwino kwambiri.
Yang'anani bwino zomwe muli nazo ndi zomwe mukusowa. Ndi zithunzi ziti zomwe mukufunikira zomwe simungathe kuzijambula? Kodi mtundu wa lens wanu wapano ndiwochepera kapena wosakwanira?
Kodi mukupita ku Prime kapena Zoom?
A Lens yayikulu amangotengera utali wokhazikika umodzi, mwachitsanzo, Tele kapena Wide, koma osati zonse ziwiri.
Izi zili ndi zabwino zingapo ndi magalasi ofanana; mtengo ndi wochepa, kuthwa kwake ndi khalidwe ndiloyenera, kulemera kwake nthawi zambiri kumakhala kotsika ndipo kukhudzidwa kwa kuwala nthawi zambiri kumakhala bwino kusiyana ndi Mawonekedwe a lens.
Ndi lens ya Zoom mutha kusintha kuchuluka kwa makulitsidwe osasintha magalasi. Ndizothandiza kwambiri kupanga zolemba zanu komanso mumafunika malo ochepa m'chikwama chanu cha kamera.
Kodi mukufuna mandala apadera?
Kwa ma shoti apadera kapena mawonekedwe apadera, mutha kusankha magalasi owonjezera:
- magalasi makamaka kuwombera kwa Macro, mukamakonda kujambula mwatsatanetsatane monga tizilombo kapena zodzikongoletsera. Ma lens okhazikika nthawi zambiri satha kuyang'ana pafupi ndi mandala
- Kapena mandala a Maso a Nsomba okhala ndi ngodya yayikulu kwambiri. Mutha kugwiritsa ntchito izi m'malo ang'onoang'ono, kapena kutengera makamera ochitapo kanthu.
- Ngati mungafune mawonekedwe a bokeh/blur (kuzama pang'ono kwa malo) pazithunzi zanu pomwe chakutsogolo ndi chakuthwa, mutha kukwaniritsa izi mosavuta mwachangu (osamva kuwala) Mapulogalamu a telephoto.
- Ndi lens lalikulu-angle mungathe kulemba chithunzi chachikulu ndipo nthawi yomweyo chithunzicho chimakhala chokhazikika kuposa pamene mukuwombera pamanja. Izi zimalimbikitsidwanso ngati mumagwira ntchito ndi gimbals / steadicms.
Kukhazikika
Ngati muli ndi kamera popanda kukhazikika, mutha kusankha mandala ndi kukhazikika. Mutha kuyiyambitsa kapena kuyimitsa malinga ndi zosowa zanu.
Pojambula ndi chowongolera, chogwirizira m'manja kapena pamapewa, izi ndizofunikira kukhala nazo ngati palibe chithunzi chokhazikika (IBIS) pa kamera.
Kuyamba ndi zolemba zanu zoyimitsa nkhani
Lembetsani ku kalata yathu yamakalata ndikutsitsa kwaulere ndi zolemba zitatu. Yambani ndikupangitsa nkhani zanu kukhala zamoyo!
Tidzangogwiritsa ntchito imelo yanu kutsamba lathu ndikulemekeza lanu zachinsinsi
Autofocus
Ngati mukujambula molamulidwa, mutha kuyang'ana pamanja.
Ngati mukujambula malipoti, kapena ngati mukufuna kuyankhapo mwachangu pazomwe zikuchitika, kapena ngati mumagwira ntchito ndi a gimbal (zabwino zina zomwe takambirana pano), ndizothandiza kugwiritsa ntchito mandala okhala ndi autofocus.
Lens ya cinema
Ojambula ambiri a DSLR ndi (olowa-level) amakanema amakamera amakanema amagwiritsa ntchito lens ya chithunzi "yabwinobwino". Lens ya Cine idapangidwa mwapadera kuti ijambule ndipo ili ndi izi:
Mutha kuyika kuyang'ana pamanja molondola komanso bwino, kusintha kabowo / kabowo ndi kopanda masitepe, palibe vuto ndi kupuma kwa mandala komanso mawonekedwe omanga nthawi zonse amakhala abwino kwambiri. Choyipa ndichakuti mandala nthawi zambiri amakhala okwera mtengo komanso olemetsa.
Kusiyana pakati pa lens ya Cine ndi lens yojambula
Muli ndi mitundu yosiyanasiyana ya magalasi ogwiritsira ntchito zosiyanasiyana. Mu gawo lapamwamba mutha kusankha pakati pa lens yojambula ndi a cine lens.
Ngati mumagwira ntchito yopanga mafilimu ndi bajeti yabwino, pali mwayi woti mudzagwire ntchito ndi ma lens a cine. Kodi n’chiyani chimapangitsa magalasi amenewa kukhala apadera kwambiri, ndipo n’chifukwa chiyani ndi okwera mtengo kwambiri?
Kulemera kofanana ndi kukula kwa lens ya Cine
Kusasinthasintha ndikofunikira kwambiri pakupanga mafilimu.
Simukufuna kukhazikitsanso yanu bokosi la matte (zosankha zina zabwino apa ndi njira) ndipo tsatirani chidwi mukasintha ma lens. Ndicho chifukwa chake mndandanda wa ma lens a cine uli ndi kukula kofanana ndi pafupifupi kulemera komweko, kaya ndi lalikulu kapena telephoto lens.
Mtundu ndi zosiyana ndizofanana
Pojambula, muthanso kusiyanasiyana mumitundu ndi kusiyanitsa ndi ma lens osiyanasiyana. Ndi filimu zimakhala zovuta kwambiri ngati chidutswa chilichonse chili ndi kutentha kosiyana ndi maonekedwe.
Ndicho chifukwa chake ma lens a cine amapangidwa kuti apereke zosiyana ndi maonekedwe a mtundu, mosasamala kanthu za mtundu wa lens.
Kupumira kwa lens, kuyang'ana kupuma ndi parfocal
Ngati mumagwiritsa ntchito lens zoom, ndikofunikira ndi lens la cine kuti mfundo yowunikira nthawi zonse imakhala yofanana. Ngati mukuyenera kuyang'ananso pambuyo pakukulitsa, ndizokwiyitsa kwambiri.
Palinso magalasi omwe mbewu yachithunzichi imasintha mukamayang'ana (kupuma kwa magalasi). Simukufuna kuti mujambule kanema.
Vignetting ndi T-Stops
Lens imakhala ndi kupindika kotero kuti disoloyo imapeza kuwala kochepa kumbali kusiyana ndi pakati. Ndi lens ya cine, kusiyana kumeneku kumakhala kochepa momwe mungathere.
Ngati chithunzicho chikuyenda, mutha kuwona kusiyana kumeneku pakuwala bwinoko kuposa ndi chithunzi. F-mayimitsa amagwiritsidwa ntchito kujambula, T-kuyima mufilimu.
F-stop imasonyeza kuchuluka kwa kuwala komwe kumadutsa mu lens, T-stop imasonyeza kuchuluka kwa kuwala komwe kumagunda sensa ya kuwala kotero ndi chizindikiro chabwino komanso chokhazikika.
Lens yeniyeni ya cine nthawi zambiri imakhala yokwera mtengo kwambiri kuposa lens ya chithunzi. Chifukwa nthawi zina mumayenera kujambula kwa miyezi ingapo, kusinthasintha ndikofunikira.
Kuphatikiza apo, mutha kuyembekezera mawonekedwe apamwamba a mandala pansi pazovuta zowunikira monga kuunikira kumbuyo, kusiyanitsa kwakukulu komanso kuwonekera kwambiri. Ubwino womanga ndi kapangidwe ka mandala ndi wolimba kwambiri.
Ambiri opanga mafilimu amabwereka magalasi a cine chifukwa mtengo wogula ndi wokwera kwambiri.
Mutha kujambula zithunzi zabwino kwambiri ndi magalasi azithunzi, koma ma lens amakanema amatsimikizira kuti mumadziwa bwino zomwe lens ikuchita pansi pamikhalidwe yonse, ndipo izi zitha kupulumutsa nthawi popanga pambuyo pake.
F-Stop kapena T-Stop?
The F-Imani amadziwika ndi ambiri ojambula mavidiyo, amasonyeza kuchuluka kwa kuwala komwe kumadutsa.
Koma mandala amapangidwa ndi magalasi osiyanasiyana omwe amawonetsa kuwala, motero amalepheretsanso kuwala.
T-Stop imagwiritsidwa ntchito kwambiri ndi magalasi a Cinema (Cine) ndipo imawonetsa kuchuluka kwa kuwala komwe kumalowetsedwa, ndipo izi zitha kukhala zochepa kwambiri.
