LED Teeb pom kev zoo: Cov Cuab Yeej Tseem Ceeb Tseem Ceeb rau Kev Kho Duab Niaj Hnub
Rau cov kws yees duab, lub teeb tsis yog ib qho cuab yeej xwb -nws yog qhov nruab nrab ntawm daim duab kos duab. Kev nkag siab thiab kev paub lub teeb yog qhov tseem ceeb, tab sis nws feem ntau nthuav tawm qhov nyuaj tshaj plaws. Thaum cov kws yees duab tau tso siab rau ntau yam ntawm cov khoom siv hluav taws xob,LED technologytau tshwm sim los ua tus khub hloov pauv, muab kev tswj tsis tau pom dua thiab ntau yam rau ob qho tib si tseem thiab txav cov duab.
Cov lus qhia no tshawb xyuas seb LEDs tau rov txhais cov duab teeb pom kev zoo li cas, delving rau hauv lub tswv yim tseem ceeb ntawm cov xim kub thiab qhov zoo sib xws uas ua rau LEDs yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub kws yees duab.
Mastering Xim Kub: Lub hauv paus ntawm Duab Mood
Qhov kev xav ntawm daim duab yog cuam tshuam los ntawm nws cov xim kub, ntsuas hauv Kelvins (K). Peb qhov kev nkag siab ntawm lub teeb yog los ntawm "sov" mus rau "txias," thiab ntau qhov chaw tsim cov huab cua sib txawv.
Lub teeb sov (2000K - 3500K):Cov kab no evokes kev xav ntawm warmth, intimacy, thiab kev nplij siab. Nws suav nrog cov mos mos, liab qab ci ntawm lub tswm ciab (ib puag ncig 1850K), lub xim kub ntawm lub hnub tuaj lossis hnub poob (2500K-3500K), thiab lub teeb los ntawm cov qhov muag teev tungsten (3200K).
Lub teeb txias (5000K - 7000K+):Cov kab no qhia meej meej, tsis muaj menyuam, lossis lub zog. Nws suav nrog lub teeb nruab nrab, sib npaug ntawm lub hnub nruab nrab (5500K), lub teeb diffuse ntawm lub ntuj overcast (7000K), thiab lub ntse xiav ntawm lub ntuj xiav ntshiab (10,000K+).
Cov koob yees duab feem ntau muaj qhov Auto White Balance (AWB) muaj nuj nqi tsim los ua kom cov xim tsis zoo nyob rau hauv ntau yam ntawm3200K (tungsten) rau 7000K (overcast ntuj). Txawm li cas los xij, cov teeb pom kev zoo tshaj plaws thiab kev xav tau feem ntau tshwm sim sab nraum qhov no. AWB tawm tsam nrog qhov sov sov ntawm lub hnub poob (hauv qab 3200K) thiab qhov txias txias ntawm qhov sib sib zog nqus twilight (siab tshaj 7000K), feem ntau robbing scenes ntawm lawv lub siab lub ntsws. Qhov no yog qhov uas tswj teeb pom kev zoo, tshwj xeeb tshaj yog LEDs, ua qhov tseem ceeb.
Qhov Zoo Tshaj Plaws ntawm LED Teeb hauv Kev Yees Duab
LED vaj huam sib luag thiab teeb tsis yog ib qho kev hloov rau cov qij qub; lawv sawv cev rau kev txhim kho tseem ceeb hauv kev ua haujlwm thiab muaj peev xwm muaj tswv yim.
1. Lub Hwj Chim Nruam "Dab tsi-Koj-Saib-Yog-Dab tsi-Koj- Tau txais" Teeb pom kev zoo
Tsis zoo li strobes los yog speedlights uas ua rau ib tug dig muag tawg ntawm lub teeb, LEDs muab ib tug tas li, tsis tu ncua kwj ntawm illumination. Qhov "modeling light" functionality yog lawv cov khoom muaj nqis tshaj plaws.
Zoo meej saib ua ntej:Nrog LED teeb, koj tuaj yeem pom qhov sib cuam tshuam ntawm lub teeb thiab duab ntxoov ntxoo ntawm koj qhov kev kawm hauv lub sijhawm tiag tiag -. Tsis tas yuav siv ntau qhov kev sim txhaj tshuaj los ntsuas seb lub teeb yuav poob li cas, qhov ntxoov ntxoo yuav raug pov tseg, lossis qhov tseem ceeb yuav cuam tshuam li cas. Qhov no tso cai rau kev teeb tsa sai dua, kev hloov kho meej dua, thiab muaj kev sib koom ua ke ntau dua nrog koj qhov kev kawm.
Txo Flash Dependence:Txawm hais tias muaj zog strobes tseem yog qhov tseem ceeb rau kev ua kom khov siab siab - nrawm nrawm lossis dhau lub hnub, LEDs txo qis kev cia siab rau hnyav, ncaj qha flash rau ntau qhov xwm txheej sab hauv tsev thiab tswj tau, ua rau ntau yam ntuj tso- saib cov txiaj ntsig.
2. Txhim kho qhov kev nplij siab thiab lub ntsej muag ntuj
Kev siv lub teeb ci LED txuas ntxiv ncaj qha rau cov teeb meem tshwm sim cuam tshuam nrog lub koob yees duab flash.
Kev tshem tawm ntawm Liab -Qhov muag:Cov nyhuv "liab-qhov muag" tshwm sim thaum lub koob yees duab lub teeb pom kev tawm ntawm lub retina ntawm cov menyuam kawm ntawv dilated nyob rau hauv lub teeb qis. Txij li thaum muaj zog flash yog qhov tsis tsim nyog nrog lub teeb ci LED tas li, qhov teeb meem no yuav raug tshem tawm.
Txo cov menyuam kawm ntawv lim thiab cov xim raug:Lub strobe muaj zog tuaj yeem ua rau cov tub ntxhais kawm ntawv cog lus thiab nthuav dav sai, ua rau tsis xis nyob thiab tsis zoo li qub - saib ob lub qhov muag hauv koob txhaj tshuaj. Qhov kev tso tawm zoo ib yam ntawm LEDs tiv thaiv qhov mob no, ua kom cov neeg kawm lub qhov muag zoo li ntuj thiab cov xim raug ua kom raug thoob plaws hauv kev tua.
3. Tsis muaj qhov sib piv hloov xim kub
Kev lig kev cai, kev ua tiav cov xim sib txawv yuav tsum muaj cov kws yees duab nqa ntau lub qhov muag teev lossis siv cov gels lub cev, uas tuaj yeem yog lub sijhawm- siv los hloov thiab ua kom lub teeb tsis zoo.
Niaj hnub nimno LED panels daws qhov teeb meem no elegantly. Ntau tus qauv kev tshaj lij featurebi-xim technology, tso cai rau koj hu rau hauv ib qho xim kub ntawm qhov dav spectrum, feem ntau los ntawm3200K (tungsten) txog 5500K (hnub ci), nrog ib qho kev sib tw. Qhov no txhais tau tias koj muaj peev xwm seamlessly phim koj LED cov zis rau lub ambient chav teeb los yog ib lub qhov rais glow kom tswj cov xim sib xws, los yog muaj tswv yim hloov mus rau hauv lub scene yam tsis tau hloov ib lub cev accessory.
4. Qhov kawg Versatility rau Hybrid Shooters
Hauv kev lag luam muaj tswv yim niaj hnub no, cov kws yees duab feem ntau xav tias yuav tsim cov duab tseem thiab cov ntsiab lus video. LEDs yog cov cuab yeej sib koom ua ke zoo tshaj plaws rau kev ua haujlwm hybrid no.
Rau Video:Tsis tu ncua, flicker -dawb illumination yog ib qho tsis yog - yuav tsum tau sib tham rau videography. LED panels yog cov qauv kev lag luam rau kev teeb pom kev video.
Rau Stills:Tib lub teeb pom kev zoo LED uas teeb rau koj qhov kev yees duab zoo kawg nkaus muaj peev xwm muab lub teeb zoo nkauj, txuas ntxiv rau koj cov duab tseem. Qhov kev ua haujlwm dual no ua rau LEDs ua tus nqi tsis txaus ntseeg - kev xaiv zoo thiab muaj txiaj ntsig zoo rau cov neeg tsim cov ntsiab lus uas ua haujlwm thoob plaws ob qhov nruab nrab.
Cov tswv yim xav txog thaum xaiv LED teeb
Txhawm rau kom ua tiav cov LEDs, xav txog cov ntsiab lus tseem ceeb no:
High CRI (Color Rendering Index) thiab TLCI (TV Lighting Consistency Index):Nrhiav cov vaj huam sib luag nrog CRI thiab TLCI ntawm95+. Qhov kev ntsuam xyuas no ua kom paub tseeb tias lub teeb pom kev zoo qhia cov xim tseeb ntawm koj cov ntsiab lus, cov xim tawv nqaij, thiab cov khoom lag luam, tiv thaiv av nkos lossis tsis zoo li qub - saib xim.
Lub zog tso zis (Lumens):Xyuas kom lub LED ci txaus rau koj cov kev xav tau, tshwj xeeb tshaj yog tias koj yuav tsum sib npaug nrog lub teeb pom kev zoo lossis siv lub aperture me me rau qhov tob ntawm qhov chaw.
Roj teeb vs AC zog:Roj teeb -powered LEDs muab kev txav mus los rau ntawm - qhov chaw tua, thaum AC - cov qauv siv hluav taws xob muab sijhawm tsis txwv rau kev ua haujlwm hauv studio.
Xaus: Lub neej yav tom ntej ci ntsa iab rau kev tswj hwm muaj tswv yim
LED thev naus laus zis yog ntau tshaj qhov yooj yim teeb pom kev zoo; nws yog ib tug muaj tswv yim muaj tswv yim khub uas txhawb cov kws yees duab nrog tam sim ntawd pom kev tawm tswv yim, unparalleled tswj ntawm cov xim, thiab seamless versatility nyob rau hauv kev yees duab thiab videography. Los ntawm kev sib koom ua ke siab - LED teeb pom kev zoo rau hauv koj qhov kev ua haujlwm, koj txav mus dhau qhov kev xav thiab mus rau hauv ib cheeb tsam ntawm qhov tseeb, txhob txwm tsim, tso cai rau koj ntes koj lub zeem muag nrog qhov pom tseeb thiab sib xws. Nyob rau hauv ib txwm muaj - hloov pauv kev kos duab ntawm kev yees duab, LEDs tau ruaj khov rau lawv tus kheej ua ib qho tseem ceeb rau kev teeb pom kev zoo thiab txhais cov style.
