Wakambotarisa LCD skrini yekamera muimba inopenya uye wakafunga kuti chifananidzo chacho chakanga chakasviba kana kuti chisina kuratidzwa?Kana kuti wakamboona chidzitiro chimwe chete munzvimbo ine rima uye ukafunga kuti chifananidzo chaive chabuda pachena?Sezvineiwo, dzimwe nguva mufananidzo unoguma hausi nguva dzose zvaunofunga kuti zvichave.
"Exposure" ndeimwe yehunyanzvi hwakakosha hwekupfura mavhidhiyo.Kunyangwe vashandisi vanogona kushandisa mufananidzo-kugadzirisa software kuita zvigadziriso mumashure-kugadzirwa, kutonga kwakaringana kuratidzwa kunogona kubatsira mutori wevhidhiyo kuwana mifananidzo yemhando yepamusoro uye kudzivirira kushandisa nguva yakawandisa mukumashure-kugadzirwa.Kubatsira vanotora vhidhiyo mukutarisa kuratidzwa kwemifananidzo, mazhinji maDSLR ane akavakira-mukati mabasa ekutarisa kuratidzwa.Semuyenzaniso, iyo Histogram uye Waveform maturusi anoshanda kune nyanzvi dzevhidhiyo.Muchinyorwa chinotevera, tiri kuzosuma maitiro akajairwa ekuwana kuratidzwa chaiko.
Histogram
Histogram Scope inoumbwa ne "X-axis" uye "Y-axis."Kune “X” axis, rutivi rworuboshwe rwegirafu runomiririra rima, uye rutivi rworudyi runomiririra kupenya.Iyo Y-axis inomiririra pixel intensity yakagoverwa mukati memufananidzo.Iyo yakakwira kukosha kwepamusoro, mapikseli akawanda aripo kune chaiyo kupenya kukosha uye nzvimbo yakakura yaanogara.Kana iwe ukabatanidza ese pixel kukosha mapoinzi paY axis, inoumba inoenderera Histogram Scope.
Kune mufananidzo wakafumurwa zvakanyanya, iyo histogram's peak value ichave yakanamirwa kurudyi rwe X-axis;Ukuwo, kune mufananidzo usina kuratidzwa, iyo histogram's peak kukosha ichave yakanamirwa kuruboshwe rwe X-axis.Kune mufananidzo wakanyatsoenderana, iyo histogram's peak value inogovera zvakaenzana pakati peiyo X-axis, kungofanana nechati yekugovera yakajairika.Uchishandisa Histogram Scope, mushandisi anogona kuongorora kana kuratidzwa kuri mukati mekupenya kwakasimba kwesimba uye ruvara rwekuzara.
Waveform Scope
Iyo Waveform Scope inoratidza kupenya uye RGB & YCbCr kukosha kwemufananidzo.Kubva kuWaveform Scope, vashandisi vanogona kuona kupenya uye rima remufananidzo.Iyo Waveform Scope inoshandura iyo yakapenya nhanho uye yakasviba mwero wemufananidzo kuita waveform.Semuyenzaniso, kana "All Dark" value iri "0" uye "All Bright" value iri "100", inoyambira vashandisi kana rima rakadzika pane 0 uye kupenya kuri pamusoro pe100 pamufananidzo.Saka, mutori wevhidhiyo anogona kubata zvirinani aya mazinga achipfura vhidhiyo.
Parizvino, basa reHistogram rinowanikwa pamakamera ekupinda-level DSLR uye mamonitor emunda.Nekudaro, chete inyanzvi yekugadzira monitors inotsigira iyo Waveform Scope basa.
Rudzi Rwenhema
Rudzi Rwenhema rwunodaidzwawo kuti "Exposure Assist."Kana False Colour Function iripo, mavara emufananidzo anozoratidzwa kana anyanya kufumurwa.Saka, mushandisi anogona kuongorora kuratidzwa pasina kushandisa mimwe michina inodhura.Kuti unyatsoona chiratidzo cheNhema Rudzi, mushandisi anofanira kunzwisisa iwo mavara anoratidzwa pazasi.
Semuenzaniso, munzvimbo dzine exposure level ye56IRE, iyo yenhema-ruvara icharatidzwa sepink color pamonitor kana yaiswa.Naizvozvo, paunowedzera kuratidzwa, nzvimbo iyoyo inochinja ruvara kuita grey, yozoita yero, uye pakupedzisira kuita tsvuku kana yakafumurwa zvakanyanya.Bhuruu inoratidza kusaratidzwa.
Zebra Pattern
Iyo "Zebra Patani" ibasa rekuratidzira-rinobatsira iro riri nyore kunzwisisa kune vashandisi vatsva.Vashandisi vanogona kuseta chikumbaridzo chikamu chemufananidzo, unowanikwa mu "Exposure Level" sarudzo (0-100).Semuyenzaniso, kana pachikumbaridzo chaiswa kuti “90″, nyevero yembizi ichaonekwa kana kupenya kuri pascreen kwasvika pamusoro pe“90”, zvichiyeuchidza mutori wemifananidzo kuti azive nezvekunyanya kuratidzwa kwemufananidzo.
