Ngaba ukhe wajonga isikrini se-LCD sekhamera kwigumbi eliqaqambileyo kwaye wacinga ukuba umfanekiso umnyama kakhulu okanye ungaphantsi?Okanye ngaba ukhe wasibona isikrini esifanayo kwindawo emnyama kwaye wacinga ukuba umfanekiso ubuvezwe ngaphezulu?Okumangalisayo kukuba, ngamanye amaxesha umfanekiso obangelwayo awusoloko ucinga ukuba uya kuba njalo.
"Ukuvezwa" sesinye sezakhono ezibalulekileyo zokufota iividiyo.Nangona abasebenzisi banokusebenzisa isoftware yokuhlela imifanekiso ukwenza uhlengahlengiso kwi-post-production, ukulawula ukuvezwa okuchanekileyo kunokunceda umzobi wevidiyo afumane imifanekiso ekumgangatho ophezulu kwaye aphephe ukuchitha ixesha elingaphezulu kwimveliso yasemva.Ukunceda abathwebuli bevidiyo ekubekeni iliso ekuvezweni kwemifanekiso, ii-DSLR ezininzi zinemisebenzi eyakhelweyo yokubeka iliso ekuvezweni.Umzekelo, i-Histogram kunye neWaveform zizixhobo eziluncedo kwiividiyo ezichwepheshile.Kwinqaku elilandelayo, siza kwazisa imisebenzi eqhelekileyo yokufumana utyhileko oluchanekileyo.
I-Histogram
I-Histogram Scope yenziwe “yi-X-axis” kunye ne-“Y-axis.”Kwi-axis ethi “X”, icala lasekhohlo legrafu limela ubumnyama, kwaye icala lasekunene limele ukuqaqamba.I-Y-axis imele ubunzulu bepixel obusasazwe kuwo wonke umfanekiso.Okukhona liphezulu ixabiso lencopho, kokukhona kukho iipikseli ezininzi zexabiso elithile lokuqaqamba kunye nendawo enkulu ehlala kuyo.Ukuba uqhagamshela onke amanqaku exabiso pixel kwi-Y axis, yenza i-Histogram Scope eqhubekayo.
Ngomfanekiso ovezwe ngokugqithisileyo, ixabiso eliphezulu le-histogram lizakugxininiswa kwicala lasekunene le-X-axis;ngokuchaseneyo, kumfanekiso ongaphantsi, ixabiso eliphezulu le-histogram lizakugxininiswa kwicala lasekhohlo le-X-axis.Ngomfanekiso olungelelaniswe ngokufanelekileyo, ixabiso le-histogram lencochoyi lisasazwa ngokulinganayo kumbindi we-X-axis, njengetshathi yosasazo eqhelekileyo.Ukusebenzisa i-Histogram Scope, umsebenzisi unokuvavanya ukuba ukuvezwa kungaphakathi kokukhanya okuguquguqukayo okuchanekileyo kunye noluhlu lokugcwala kombala.
Umda weWaveform
Umda weWaveform ubonisa ukukhanya kunye neRGB & YCbCr amaxabiso omfanekiso.Ukusuka kuMda weWaveform, abasebenzisi banokujonga ukukhanya kunye nobumnyama bomfanekiso.Umda weWaveform uguqula inqanaba eliqaqambileyo kunye nenqanaba elimnyama lomfanekiso libe yifomam yamaza.Umzekelo, ukuba ixabiso elithi "All Dark" lithi "0" kwaye ixabiso elithi "All Bright" lithi "100", liya kubalumkisa abasebenzisi ukuba umgangatho omnyama ungaphantsi kwe-0 kunye nenqanaba lokukhanya lingaphezulu kwe-100 emfanekisweni.Ke, umzobi wevidiyo unokulawula ngcono la manqanaba ngelixa udubula ividiyo.
Okwangoku, umsebenzi we-Histogram uyafumaneka kwiikhamera ze-DSLR zenqanaba lokungena kunye nabahloli bendawo.Nangona kunjalo, kuphela ngabahloli bemveliso abaqeqeshiweyo abaxhasa umsebenzi weWaveform Scope.
Umbala wobuxoki
Umbala ongeyonyani ukwabizwa ngokuba yi "Exposure Assist."Xa uMsebenzi woMbala ongeyonyani ulayitiwe, imibala yomfanekiso iya kuphawulwa ukuba icace kakhulu.Ke, umsebenzisi unokuhlola ukuvezwa ngaphandle kokusebenzisa ezinye izixhobo ezibizayo.Ukuqonda ngokupheleleyo isalathiso soMbala wobuxoki, umsebenzisi kufuneka aqonde umbala oboniswe ngezantsi.
Ngokomzekelo, kwiindawo ezinezinga lokuvezwa kwe-56IRE, umbala wobuxoki uya kuboniswa njengombala opinki kwimonitha xa usetyenziswa.Ke ngoko, njengoko unyusa utyhileko, loo ndawo iya kutshintsha umbala ube ngwevu, emva koko ube tyheli, kwaye ekugqibeleni ube bomvu ukuba utyhileke kakhulu.Okuluhlaza okwesibhakabhaka kubonisa ukungatyhileki.
Ipateni yeZebra
"Ipateni yeZebra" ngumsebenzi wokunceda ekulula ukuwuqonda kubasebenzisi abatsha.Abasebenzisi banokubeka inqanaba lomda womfanekiso, okhoyo kwi-"Exposure Level" ukhetho (0-100).Umzekelo, xa umphakamo usetelwe ku-“90″, isilumkiso sepateni yeqwarhashe siyakuvela nje ukuba ukukhanya kwesikrini kufikelele ngaphezulu kuka-“90”, kukhumbuze umfoti ukuba aqaphele ukuvezwa komfanekiso ngokugqithisileyo.
