Hana mākou i ʻekolu laina ʻokoʻa o nā kukui bias:

• Maikaʻi loa: LX1 Bias Kauila, kā mākou koho kumu kūʻai haʻahaʻa me kahi CRI o 95, a me ka nui o LED 20 no ka mika
• maikai: MediaLight Mk2, ʻO kā mākou koho kaulana loa, me kahi CRI o ≥ 98, a me LED density o 30 no ka mika
• Best: MediaLight Pro2, kā mākou huahana mua, me ka ʻenehana emitter hou a me kahi CRI o 99, a me ka nui LED o 30 no ka mika. 

A ʻo ka ʻoiaʻiʻo, ʻo kekahi o kēia mau kukui e lawa pono e hoʻohana i kahi hoʻonohonoho ʻoihana a i ʻole me kahi TV calibrated ma ka home.

Eia naʻe, loaʻa iā mākou ka nui o nā leka uila a me nā noi kamaʻilio e nīnau ana i kahi ʻāpana e kūʻai ai. Makemake au e kaʻana like i koʻu mau manaʻo e pili ana i ke kumuhana me nā mea a mākou i aʻo ai mai nā mea kūʻai aku i koho. 

E noʻonoʻo i kāu TV ma ke ʻano o ka "maikaʻi," "ʻoi aku ka maikaʻi" a i ʻole "ʻoi aku ka maikaʻi" a hoʻoholo i kāu hoʻoholo kūʻai. 

Manaʻo mākou i ka "10% rule," a i ʻole ka mālama ʻana i ke kumukūʻai o nā mea pono e like me ke kukui bias i 10% o ke kumu kūʻai o ke TV a i ʻole.

Ma o ka noiʻi ʻana o nā mea kūʻai aku a me nā kamaʻilio pūnaewele, ua aʻo mākou ʻaʻole makemake nā mea kūʻai aku e uku ma mua o 10% o ke kumu kūʻai o ke TV ma nā lako. I nā huaʻōlelo ʻē aʻe, ʻaʻole makemake nā mea kūʻai aku e kau i nā kukui $100 ma kahi TV $300. 

He manaʻo ʻole kēia, akā hana maʻamau ma ke ʻano he "rula gula" no ka mea ua hoʻokomo ʻia nā TV ma ke ʻano "maikaʻi" i nā ʻano kālepa like ʻole e hiki ai i kā lākou kumu kūʻai. Hiki i nā TV ma kēia māhele ke loa'a ka pōmaika'i nui mai ka ho'omālamalama 'ana ma muli o ka emi 'ana o ka mohala a me ka ho'omaika'i 'ana i ke 'ano like 'ole i waena o kāna mau pono kaulana loa. 

Ma ke ʻano he hui, ʻike mākou e ulu nui ana nā TV, me nā hiʻohiʻona waiwai-hana ma ke kumu kūʻai haʻahaʻa. Pono mākou e ʻimi i kahi ala e hoʻololi ai i kā mākou kikoʻī e hāʻawi i ka pololei i ʻike ʻia no mākou, akā ma ke kumu kūʻai ʻoi aku ka maikaʻi, ʻoi aku hoʻi i nā lōʻihi lōʻihi e lilo i mea kaulana. 

Ua hana mākou i kēia ma ka hoʻohaʻahaʻa ʻana i ka nui o nā LED, a i ʻole ka helu o nā LED i kēlā me kēia mika, ma ka LX1 i kahi kikoʻī e pili kokoke ana i ka mea āu e ʻike ai ma nā ʻāpana LED-powered USB haʻahaʻa. Ke nīnau nā mea kūʻai i ke kumu i ʻoi aku ka pipiʻi o MediaLight, pane pinepine mākou he mau LED ʻoi aku ka maikaʻi, a ʻoi aku ka nui o ia mau mea i kēlā me kēia kaula. Pono mākou e hana i ka laina LX1 o nā kukui bias no ka pakele ʻana i kēlā koi kikoʻī, ʻaʻohe hopena i ka maikaʻi o ke kukui inā lōʻihi ka nui o ka lumi no nā kukui e laha ma ka paia. 

Hana ʻia nā ʻāpana LED ColorGrade LX1 i ka manawa like me nā pahu Mk2. Hoʻokaʻawale mākou i nā mea maikaʻi loa - nā LED me CRI ≥ 98, a hoʻohana iā lākou i ka Mk2. ʻO nā ʻāpana ʻē aʻe, me nā hoʻonohonoho chromaticity like, a me kahi CRI ma waena o 95 a me 97.9, hoʻohana ʻia i ka LX1. ʻO lākou, no nā manaʻo āpau, "he pāʻani." Hiki iā ʻoe ke hoʻohana iā lākou i ka hoʻonohonoho like. 

No laila, ʻoi aku ka maikaʻi o ka MediaLight Mk2 ma mua o LX1 ma ke ʻano o ka hana?

ʻAe, ʻoi aku ka pololei.

Inā ʻoe e ana i nā kukui bias ma lalo o kahi spectrophotometer, e ʻike ʻoe he haʻahaʻa iki ka CRI o ka LX1 ma mua o ka Mk2. Eia naʻe, ma nā ʻōlelo kūpono, ʻaʻole e pōmaikaʻi nā kānaka a pau mai kēia hoʻomaikaʻi ʻana i ka pololei. ʻOi aku kēia ma luna o ke kanaka. Inā ʻike ʻoe iā ʻoe iho he koi nui, ʻoi aku ka manaʻo o ka Mk2. Inā ʻoe e hōʻike ana i kāu hōʻike ʻoihana-calibrated, ʻoi aku ka manaʻo o ka Mk2. Inā ʻoe e hoʻolilo i ka manawa nui i mua o kāu hōʻike, ʻoi aku ka manaʻo o ka Mk2 i ka ʻōlelo o ka pololei a me ka lōʻihi o ka manawa hoʻopaʻa (5 mau makahiki me 2 mau makahiki no LX1). 

Inā ʻo ʻoe ke ʻano o ke kanaka e ʻōlelo nei, a ke olelo nei au, "ʻAʻole au e kala mai iaʻu iho inā ʻaʻole wau e loaʻa i nā mea hana maikaʻi loa i loaʻa," pono paha ke kiʻi i ka Mk2. (Akā e ʻike wale ʻoe e maikaʻi paha ʻoe me ka LX1). 

Pela no na TV me na puu flush loa. ʻO ke kiʻekiʻe o ka LED kiʻekiʻe ma ka Mk2 e hāʻawi i kahi hoʻopuni i ʻoi aku ka pōʻeleʻele i kēia mau hihia no ka mea he liʻiliʻi ka mamao ma waena o kēlā me kēia LED. 

ʻAe, aia ma hea ka MediaLight Pro2 i kēia kūkākūkā? 

E like me ke kūkulu ʻana i ka MediaLight Pro kumu i aʻo mai iā mākou pehea e hoʻomaikaʻi ai i kā mākou hua a me ka pololei e hana ai i ka MediaLight Mk2, manaʻo mākou e hilinaʻi kā mākou huahana e hiki mai ana iā mākou e hiki ke hoʻokō i nā hua maikaʻi a me ka nui me nā ʻenehana hou. ʻO ia ke kumu aʻu e ʻōlelo ai ʻo ka MediaLight Pro2 kā mākou huahana i mua. ʻO kā mākou hana, ma nā mahina he 12-18 e hiki mai ana, ʻo ia ka hōʻemi i ka hana a me ke kumu kūʻai ma waena o ka pae MediaLight Mk2 a me ka Pro2. 

I kēia manawa, ʻoi aku ka nui o ke kumukūʻai o ka MediaLight Pro2 no ka hana ʻana a ʻoi aku ia ma mua o ke kānāwai 10% i nā hihia he nui, ʻoi aku hoʻi no nā paʻi lōʻihi ma nā hōʻike nui. Eia nō naʻe, ma $69 no ka ʻāpana mika hoʻokahi, ua kūpono ka Pro2 i ke kānāwai no nā mea nānā kamepiula he nui. 

He nani ka MPro2 LED chip pono'ī. Ua wehewehe ʻia ka maikaʻi o ke kukui e like me "ka lā ma kahi ʻāpana LED" e kekahi malihini kipa ma NAB 2022, ma muli o kona kiʻekiʻe kiʻekiʻe spectral like index (SSI) i D65 (ua like ke ʻano o ka mana spectral e like me ka lā, me ka ʻole o ka spike polū. loaʻa i ka hapa nui o nā LED). Ma kahi papa helu helu, ʻoi aku me kahi hōʻike hiki loa, ʻo ka MediaLight Pro2 kahi mea hoʻohui maikaʻi loa. 

No ka hoʻopaʻa hou ʻana, lawa pololei kā mākou mau kukui bias e hoʻohana i kahi ʻoihana ʻoihana. ʻOi aku lākou a pau i nā kūlana ʻoihana e like me ka mea i hoʻonohonoho ʻia e nā hui e like me ISF, SMPTE a me CEDIA. 

Hōʻike ka "10% rule" i ka ʻoiaʻiʻo. He maʻalahi. Ua haʻi mai nā mea kūʻai aku iā mākou ʻaʻole lākou e kūʻai i kā mākou huahana ma muli o ke kumukūʻai, akā ʻaʻole lākou e kānalua inā hiki iā mākou ke mālama i kā mākou pololei ma ke kumu kūʻai haʻahaʻa. Hoʻolohe mākou, a hana mākou i ka LX1 Bias Lighting e hana i kēlā. 

Hoʻokahi nīnau hou i loaʻa iā mākou he nui:

No ke aha mākou i kapa ʻole ai i ka LX1 "The MediaLight LX1?"

Ua makemake mākou e pale i ka huikau.

Ua hopohopo mākou e hoʻāʻo nā mea kūʻai kūʻai kūʻai e hoʻopau i kā mākou LX1 ma ke ʻano he MediaLight. Hiki iā lākou ke kūʻai i LX1 no $25 a hoʻāʻo e hoʻolilo iā ia ma ke ʻano he $69 MediaLight Mk2. Hana ʻia ʻo Mk2 a me LX1 i ka ʻaoʻao ʻaoʻao, akā aia kahi ʻokoʻa i ka density LED a me CRI. ʻAʻole mākou i makemake i kā lākou mea kūʻai aku e uku no nā maʻamau MediaLight a noʻonoʻo no ke aha i emi ai nā LED ma kēlā me kēia kaula ma mua o ka wā ma mua.
