Njira Zothandizira Kuwonekera Moyenera

Kodi munayamba mwayang'ana pazithunzi za LCD za kamera mu chipinda chowala ndikuganiza kuti chithunzicho chinali chochepa kwambiri kapena chosawonekera?Kapena mudawonapo chinsalu chomwechi pamalo amdima ndikuganiza kuti chithunzicho chinali kuwonetsedwa kwambiri?Zodabwitsa ndizakuti, nthawi zina chithunzi chotsatira sichikhala chomwe mukuganiza kuti chidzakhala.

"Exposure" ndi imodzi mwamaluso ofunikira pojambulira makanema.Ngakhale ogwiritsa ntchito amatha kugwiritsa ntchito pulogalamu yosinthira zithunzi kuti asinthe zomwe apanga pambuyo pake, kuyang'anira mawonekedwe olondola kungathandize wojambula zithunzi kupeza zithunzi zapamwamba ndikupewa kuwononga nthawi yochulukirapo popanga pambuyo pake.Pofuna kuthandizira ojambula mavidiyo kuti ayang'anire chithunzithunzi, ma DSLR ambiri ali ndi ntchito zowonjezera kuti aziyang'anira kuwonekera.Mwachitsanzo, Histogram ndi Waveform ndi zida zothandizira akatswiri ojambula mavidiyo.M'nkhani yotsatirayi, tikuwonetsani magwiridwe antchito ofunikira kuti muwonetsetse bwino.

Histogram

Histogram Scope imapangidwa ndi "X-axis" ndi "Y-axis."Kwa "X" axis, mbali yakumanzere ya graph imayimira mdima, ndipo kumanja kumayimira kuwala.Y-axis imayimira mphamvu ya pixel yomwe imagawidwa pachithunzi chonse.Kukwera kwamtengo wapamwamba, kumakhala ma pixel ochulukirapo a mtengo wowala komanso malo okulirapo omwe amakhala.Mukalumikiza mfundo zonse za pixel pa Y axis, imapanga Histogram Scope yosalekeza.

Pachithunzi chowonekera kwambiri, mtengo wapamwamba wa histogram udzakhazikika kumanja kwa X-axis;kumbali ina, kwa chithunzi chosawoneka bwino, mtengo wapamwamba wa histogram udzakhazikika kumanzere kwa X-axis.Kuti mukhale ndi chithunzi choyenera, nsonga ya histogram imagawidwa mofanana pakati pa X-axis, monga tchati chogawa bwino.Pogwiritsa ntchito Histogram Scope, wogwiritsa ntchito amatha kuwunika ngati mawonekedwewo ali mkati mwa kuwala koyenera kosinthika komanso kuchuluka kwamitundu.

Waveform Scope

The Waveform Scope ikuwonetsa kuwala ndi RGB & YCbCr zachithunzichi.Kuchokera pa Waveform Scope, ogwiritsa ntchito amatha kuwona kuwala ndi mdima wa chithunzicho.Waveform Scope imasintha mulingo wowala ndi mulingo wakuda wa chithunzi kukhala mawonekedwe ozungulira.Mwachitsanzo, ngati mtengo wa "All Dark" ndi "0" ndipo mtengo wa "All Bright" ndi "100", umachenjeza ogwiritsa ntchito ngati mulingo wamdima ndi wotsika kuposa 0 ndipo mulingo wowala uli wapamwamba kuposa 100 pachithunzichi.Chifukwa chake, wojambula mavidiyo amatha kuyendetsa bwino magawowa pojambula kanema.

Pakadali pano, ntchito ya Histogram ikupezeka pamakamera olowera a DSLR ndi oyang'anira minda.Komabe, owunikira akatswiri okhawo omwe amathandizira ntchito ya Waveform Scope.

Mtundu Wonama

Mtundu Wonama umatchedwanso "Exposure Assist."False Colour Function ikayatsidwa, mitundu yachithunzi imawonetsedwa ngati iwonetsedwa mopitilira muyeso.Chifukwa chake, wogwiritsa ntchito amatha kuyang'ana mawonekedwe osagwiritsa ntchito zida zina zodula.Kuti azindikire bwino za mtundu wa False Colour, wogwiritsa ntchito ayenera kumvetsetsa mtundu womwe uli pansipa.

Mwachitsanzo, m'malo omwe ali ndi mawonekedwe a 56IRE, mtundu wabodza udzawonetsedwa ngati mtundu wapinki pa chowunikira ukagwiritsidwa ntchito.Chifukwa chake, mukakulitsa mawonekedwe, malowo amasintha mtundu kukhala imvi, kenako achikasu, ndipo pamapeto pake amakhala ofiira ngati atawonekera kwambiri.Buluu akuwonetsa kusayembekezeka.

Chithunzi cha Zebra

"Zebra Pattern" ndi ntchito yothandizira kuwonekera yomwe ndiyosavuta kumvetsetsa kwa ogwiritsa ntchito atsopano.Ogwiritsa ntchito amatha kukhazikitsa gawo lachithunzichi, lomwe likupezeka mu "Exposure Level" (0-100).Mwachitsanzo, mulingo wa pakhomo ukakhazikitsidwa kukhala “90″, chenjezo la kachitidwe ka mbidzi lidzawoneka kuwala kwa zenera kukafika pamwamba pa “90”, kukumbutsa wojambulayo kuti azindikire kuchulukira kwa chithunzicho.
