MediaLight vs. Lumadoodle: Qhov Txawv Tseem Ceeb

Nyob zoo MediaLight:

Kuv tsuas pom koj lub vev xaib xwb. Kuv tuaj ntawm Lumadoodle uas kuv tau puas ntsoog thaum kuv tsiv mus rau lwm lub tsev tshiab. Puas muaj laj thawj yog vim li cas koj cov teeb ua nqi ntau dua? Zoo li koj tuaj yeem qhia kuv cov ntaub ntawv tiag tiag?

Amrit S.

Kuv tuaj los Amrit.

Ua tsaug rau koj cov lus thiab thov zam txim rau cov lus teb ncua. Peb tau txais cov lus nug ntawd ntau heev. Kuv ib txwm teb cov lus nug ntawm kuv tus kheej:

Puas yog koj tau txuag nyiaj yog tias koj yuav ib yam khoom uas tsis ua qhov nws yuav tsum ua?

Peb ua rau txoj kev teeb nqi hluav taws xob tsawg dua uas ua rau muaj nqi zoo ib yam li Lumadoodle, thaum muab cov kev tshaj lij ntawm cov neeg muaj peev xwm, kev tiv thaiv ntev dua thiab ntau txoj kev sib txuas. 

Yog li, yog tias koj tab tom nrhiav ua qhov kev sib piv uas tsim nyog dua, kuv yuav piv Lumadoodle rau cov khoom tshiab LX1 Bias Teeb Pom Kev Zoo los ntawm tib pab pawg MediaLight.

Muaj ntau yam ntxiv rau kev txiav txim siab qhov tsis ncaj ncees dua li siv qis CRI (tsuas yog 75 Ra) mus pw hav zoov LED txoj hlua, "hle lub raj yas thiab muab daim nplaum rau tom qab," raws li Lumadoodle xav kom koj ntseeg.

Yog tias koj tsis xav tau qhov tsis zoo cuam tshuam TV duab, tom qab ntawd muaj cov qauv rau CRI (Cov Xim Ntsuas Ua Ntsuas), chromaticity thiab spectral lub zog faib cov teeb pom kev zoo uas sshould tau ua raws. 

Peb lub tuam txhab tau siv xya xyoo los txhim kho qhov raug thiab cov yam ntxwv ntawm peb cov khoom thaum lawv tsis tau zoo txhua, thiab peb paub tias tseem muaj chaw rau kev txhim kho, uas yog vim li cas peb ib txwm ua haujlwm ntawm qhov kev hloov kho ntxiv. Vim li no MediaLight cov khoom lag luam tau siv los ntawm cov kws tshaj lij video ntawm txhua lub studio thiab post chaw tsim khoom. 

Nws mus yam tsis tau hais, tab sis peb tsis txhua muaj feem nrog Lumadoodle, Govee, Antec, Zabiki lossis lwm tus neeg .. Txawm li cas los xij, dab tsi ua raws li kev zam kev xav thiab tsom rau cov ntaub ntawv spectrophotometric thiab kev tsim lub cev. 

Tab sis, rov qab rau koj cov lus nug. Kuv xav tuaj yeem xa ib lo lus teb nrog tseeb cov ntaub ntawv, yog li kuv tsuas tau txiav txim tshiab Lumadoodle chav ntsuas thiab ntsuas nws hauv qab Sekonic C7000.

Ua ntej tshaj, cia peb hle cov khaub ncaws tawm ntawm lawv cov ntim sib txawv thiab saib ntawm Lumadoodle ntawm ib sab MediaLight. Thawj qhov koj yuav pom yog MediaLight muaj ntau LEDs. Lub 5m Lumadoodle sawb muaj 90 LEDs. Ib qho MediaLight ntawm tib qhov ntev muaj 150 LEDs. Muaj 66.66% ntau LEDs ntawm MediaLight ib 'meter'. 

Sib piv Lumadoodle thiab MediaLight 
Caj Npaum LED

 

Cov chips hauv MediaLight yuav raug nqi 66% ntxiv rau LED ntau ib leeg txawm hais tias ua kom tau qis dua, qhov siab dua SMD chips tsis raug nqi ntau dua los tsim khoom. Qhov tseeb yog, lawv cov nqi tsawg kawg 20 npaug ntxiv rau ib qho LED. 

Muab piv rau kev tsis ncaj ncees lub teeb ci LED Zoo

Ua ntej tshaj plaws, cia kuv tsuas hais tias qhov no tsis yog kev sib piv ntawm txiv apples yog-rau-txiv apples.

MediaLight yog tsim los ntawm kev sim cov tub txawg tub ntse Lumadoodle tsis yogCov. MediaLight muaj cov cai Colorgrade Mk2 chips thiab Lumadoodle tsis yog. Qhov ntawd tsis yog mus khob cov neeg ua haujlwm nyob rau ntawd, vim tias lawv yog cov neeg zoo nkauj, lawv tsuas yog tsis xav txog cov duab zoo thaum tsim lawv cov khoom thiab ua siab ncaj rau nws. Peb nyiam qhov no rau cov tuam txhab uas tseem muag qes qes qes tab sis thov kom raug. 

Kuv tau sim ib Lumadoodle ob peb xyoos dhau los thiab xav tias, zoo li nrog ntau yam ntawm thev naus laus zis, tias yuav muaj kev txhim kho ntau ntxiv txij thaum ntawd los. Hauv qhov tseeb tiag, CRI (xim hloov ua kev ntsuas) tseem tsawg heev txawm hais tias LED technology tau nce siab heev dhau 5 xyoo dhau los.

Lumadoodle Xim qhia Qhov Ntsuas (CRI) = 76.3 Ra (tsis txaus)
MediaLight xim Rendering Index (CRI) ≥ 98 Ra 

Txog kev sib piv, thawj zaug (kev sim tom qab beta) MediaLight muag hauv 2015 muaj qhov CRI ntawm 91 (tam sim no 98-99 Ra). Tab sis, txawm tias MediaLight ntawm 2015 muaj CRI siab dua li Lumadoodle txog niaj hnub no.

Txoj hlua tshiab ntsuas sov dua li cov sawb dhau los, rau qhov uas koj tseem tuaj yeem pom kuv ntsuas ntawm no Los ntawm 2017, tab sis tseem tubntxhais ze rau lawv qhov kev tshaj tawm CCT ntawm 6000K (piv txwv li 6500K siv qauv). 

Kuv txhais li cas tubntxhais kaw?

Lub ntiaj teb ntawm bias teeb pom kev zoo yog qus Sab Hnub Poob. Muaj cov qauv kev lag luam nruj heev, tab sis ob peb zoo li ua raws lawv.

Peb xa peb cov khoom rau cov ntawv pov thawj ywj siab los ntawm ISF, thaum cov tuam txhab feem ntau tsuas luam "6500K" rau hauv pob, lossis "dawb huv", lossis "dawb tseeb." Kuv ib zaug yuav ib qho los sim qhov uas hais tias "zoo siab dawb" ntawm pob. 😁

Ob ntawm qhov ua txhaum cai tshaj plaws, txawm yog Vansky thiab Antec. Lawv tau phem heev uas lawv tau mob siab siv lawv. Yog tias koj tau taug kev hauv theem ntaiv lossis chaw nres tsheb nrog kab kev lom zem, lub teeb hnyav, koj paub kuv txhais tau li cas. 

Vansky Teeb Pom Kev thov xim kub ntawm 6500K rau lawv lub vev xaib tab sis ntsuas ntawm ze li ntawm 20,000K

Antec Bias Teeb Pom Kev Zoo tau hais tias lawv lub teeb tau "kom meej meej kom mus rau 6500K" ntawm lawv lub vev xaib tab sis lawv ntsuas ntawm 54,000K.  Tsis yog yuav mus txiav nws, lawv yeej txaus ntshai heev. 

Qhia tawm cov lus qhia no, Zabiki thiab Halo Bias Teeb Pom Kev Zoo Lawv kuj tau mob siab rau lawv tus kheej txoj cai, tab sis, hmoov zoo, lawv twb tawm ntawm kev lag luam, yog li kuv tsis tas yuav rov txheeb xyuas lawv ntxiv lawm.

Yog li, lo lus teb luv yog tias nws raug nqi ntau dua los tsim MediaLight vim tias tseem muaj ntau dua LEDs, uas yog lawv tus kheej ntawm kev ua tau zoo dua - ua rau cov txiaj ntsig "cov qauv siv," ntxiv rau ib pawg ntawm lwm qhov uas koj xav tau los ua ib txoj hlua LED. teeb pom kev zoo tag nrho-ua haujlwm:

  • CRI ntawm ≥98 hloov 76 (teeb ci ntsa iab yuav tsum yog qhov tsawg kawg nkaus ntawm 90)
  • Yuav tsum tso rau hauv (rau 50K txog 6500K)
  • Cov ntshiab tooj liab tsim ua PCB
  • Ntau qhov ntau ntxiv uas koj xav tau yuav khoom sib cais nrog lwm cov teeb (xws li dimmam thiab Tej thaj chaw deb, adapter, rau / tawm toggle, txuas txuas ntxiv, xaim lub tsheb kauj). 
  • Kuv puas tau hais tawm txog 66.66% ntau LEDs hauv ib daim hlab?

I cog lus hais tias kuv yuav mus tau rau hauv cov ntaub ntawv raw khoom sai sai. Tab sis ua ntej kuv ua, muaj, ib qho tsis meej pem ntawm Lumadoodle khoom lag luam uas ua rau muaj kev kub ntxhov ntau, thiab uas ua rau ntau cov email thiab web chats rau kuv. 

Kuv tsis sim Lumadoodle Pro vim tias yog lawv zoo siab los tshaj tawm ib qho spec uas tseem phem dua li lawv lub teeb dawb, uas yog qhov zoo txaus rau kuv. Xijpeem, yog tias koj kawm tsuas yog ib qho los ntawm email no: "hloov xim tsis ncaj ncees teeb thiab xim acuity tsis sib xyaw.

Txhua MediaLight strips yog simulated D65 dawb. Lawv tsis hloov xim. 

Yog li ntawd, peb cov kev sib piv yog ntawm MediaLight Mk2 thiab Lumadoodle dawb.

Ntawm no yog cov ntaub ntawv nyoos hauv .csv hom ntawv rau kev ntsuas los ntawm ob lub teeb pom kev coj los nrog Sekonic C7000 tshem tawm ntawm 18% grey daim npav hauv chav tsev pleev xim nrog Munsell N8 xim. (Koj tuaj yeem pom peb qhov sib sau ua ke ntawm lwm nplooj ntawv. Peb siv qhov ntawd los kuaj LEDs, lub teeb thiab lub taub hau teeb, tsis suav cov kab sib sau).
