Ubuhanga bwo Kumenyekanisha Gukosora

Waba warigeze kureba LCD ya kamera ya kamera mucyumba cyiza ukibwira ko ishusho yari yijimye cyangwa idashyizwe ahagaragara?Cyangwa wigeze ubona ecran imwe mubidukikije byijimye ukibwira ko ishusho yagaragaye cyane?Igitangaje, rimwe na rimwe ishusho yavuyemo ntabwo buri gihe nkuko ubitekereza.

“Exposure” ni bumwe mu buhanga bukenewe bwo gufata amashusho.Nubwo abakoresha bashobora gukoresha porogaramu yo guhindura amashusho kugirango bahindure ibicuruzwa nyuma yumusaruro, gucunga neza imurikagurisha birashobora gufasha uwufata amashusho kubona amashusho meza kandi akirinda kumara umwanya munini nyuma yumusaruro.Gufasha abavuga amashusho mugukurikirana amashusho, DSLR nyinshi zubatswe mubikorwa byo kugenzura ibyerekanwe.Kurugero, Histogramu na Waveform nibikoresho byoroshye kubafata amashusho babigize umwuga.Mu kiganiro gikurikira, tugiye kumenyekanisha imikorere isanzwe yo kubona neza.

Histogram

Scogramme Scope igizwe na “X-axis” na “Y-axis.”Kuri “X” umurongo, uruhande rw'ibumoso rugereranya umwijima, naho uruhande rw'iburyo rugaragaza umucyo.Y-axis yerekana pigiseli ubukana bwagabanijwe kumashusho.Kurwego rwohejuru agaciro, pigiseli nyinshi zirahari kumurongo wihariye wumucyo nubuso bunini bufitemo.Niba uhuza pigiseli yagaciro yose kuri Y axis, ikora Scogramu ikomeza.

Kubishusho birenze urugero, amateka ya histogramu azibanda kuruhande rwiburyo bwa X-axis;muburyo bunyuranye, kubishusho idasobanutse, agaciro ka histogramu izibanda kuruhande rwibumoso bwa X-axis.Kumashusho aringaniye neza, amateka ya histogramu yagabanijwe neza hagati ya X-axis, nkibishushanyo mbonera bisanzwe.Ukoresheje Histogramu Scope, uyikoresha arashobora gusuzuma niba imurikagurisha riri muburyo bwiza bwumucyo hamwe nurwego rwuzuye.

Umuhengeri

Umuyoboro wa Waveform werekana urumuri na RGB & YCbCr kubishusho.Uhereye kuri Waveform Scope, abayikoresha barashobora kwitegereza umucyo numwijima.Umuyoboro wa Waveform uhindura urwego rwiza kandi urwego rwijimye rwishusho kumurongo.Kurugero, niba "All Dark" agaciro ari "0 ″ naho" All Bright "agaciro ni" 100 ″, bizaburira abakoresha niba urwego rwijimye ruri munsi ya 0 naho urumuri rukaba ruri hejuru ya 100 mumashusho.Rero, videwo irashobora kuyobora neza urwego mugihe urasa amashusho.

Kugeza ubu, imikorere ya Histogram iraboneka kumurongo winjira-urwego rwa DSLR hamwe na monitor ikurikirana.Nyamara, gusa abakurikirana umwuga wabigize umwuga bashyigikira imikorere ya Waveform Scope.

Ibara ritari ryo

Ibara ry'ikinyoma naryo ryitwa "Exposure Assist."Mugihe Imikorere y'Ibinyoma Imikorere iri, amabara yishusho azagaragazwa niba arenze urugero.Noneho, umukoresha arashobora gusuzuma ibyerekanwa adakoresheje ibindi bikoresho bihenze.Kugirango umenye neza ibara ryibinyoma, umukoresha agomba gusobanukirwa ibara ryerekana hepfo.

Kurugero, mubice bifite urwego rugaragaza 56IRE, ibara-ibinyoma bizerekanwa nkibara ryijimye kuri monite iyo ushyizwe mubikorwa.Kubwibyo, nkuko wongera kwerekanwa, ako gace kazahindura ibara ryijimye, hanyuma umuhondo, hanyuma uhindure umutuku niba bikabije.Ubururu bwerekana kutitonda.

Icyitegererezo cya Zebra

"Zebra Pattern" nigikorwa-gifasha ibikorwa byoroshye kubyumva kubakoresha bashya.Abakoresha barashobora gushiraho urwego ntarengwa rwishusho, ruboneka muburyo bwa "Exposure Urwego" (0-100).Kurugero, mugihe urwego ntarengwa rwashyizwe kuri "90 ″, umuburo wa zebra uzaboneka mugihe umucyo uri muri ecran ugeze hejuru ya" 90 ″, ukibutsa uwifotora kumenya neza ishusho ikabije.
