Nws yog qhov paub zoo tias kev thaij duab nyob ze thaum lub teeb tshwj xeeb yog qhov tsaus ntuj, txawm tias muaj zog npaum li cas lub teeb qis thiab lub teeb tsaus nti, tsis muaj flash tuaj yeem tua, suav nrog SLR. Yog li ntawm lub xov tooj, nws tau spawned daim ntawv thov ntawm LED flash.

Txawm li cas los xij, vim muaj kev txwv ntawm cov khoom siv thev naus laus zis, feem ntau ntawm cov teeb ci LED tam sim no yog tsim los ntawm lub teeb dawb + phosphor, uas txwv cov spectral ntau yam: xiav lub teeb lub zog, lub teeb ntsuab thiab liab lub zog me me, yog li siv cov xim ntawm cov duab coj los ntawm LED flash yuav distorted (dawb, lub suab txias), thiab vim yog cov teeb meem spectral thiab phosphor liab, nws yog qhov yooj yim rau cov duab thiab cov xim ntawm lub qhov muag. dab tuag, txawm tias tom qab lig "facelift" Lub software kuj nyuaj rau kho.

Yuav ua li cas daws tau lub xov tooj ntawm tes tam sim no? Feem ntau, ob chav xim kub ob chav LED flash daws siv lub teeb ci LED dawb + LED sov xim lub teeb yog ua kom tsis muaj spectrum ntawm LED dawb lub teeb los ntawm kev siv LED sov xim lub teeb, yog li simulating lub spectrum uas yuav luag tag nrho coincides nrog lub ntuj hnub ci spectrum, uas yog sib npaug rau tau txais lub ntuj sab nraud lub teeb ntawm lub hnub ua rau lub teeb lub teeb xim ntawm daim tawv nqaij, tshem tawm cov xim zoo tib yam, thiab tshem tawm cov xim ntawm daim tawv nqaij. lub flare thiab qhov muag liab.

Yog lawm, nrog rau kev tsim kho tshiab ntawm thev naus laus zis, xws li ob-xim kub dual-flash tau siv dav rau cov xov tooj ntse, thiab cov kev teeb tsa zoo li no tau siv rau cov xov tooj ntse ntawm qhov loj.
