Amamodi we-In-Camera Metering abonisiwe

Uma une-DSLR, kungenzeka ukuthi uke wezwa ngamamitha. Kepha ungahle ube nenkungu kancane ukuthi iyini, yiziphi izinhlobo ezikhona, noma ukuthi ungayisebenzisa kanjani.  Ungakhathazeki! Ngilapha ukuzosiza!

Kuyini ukumitha?

Ama-DSLR ane- amamitha wokukhanya akhelwe ngaphakathi. Bangamamitha akhanyayo, okusho ukuthi balinganisa ukukhanya okukhonjiswe kubantu / ezigcawini. Azinembe kangako njengamamitha alula aphethwe ngesandla (isigameko), kepha enza umsebenzi omuhle kakhulu. Imitha yakho uqobo ingaphakathi kwekhamera yakho, kepha ungabona ukufundwa kwayo kusitholi sokubuka sekhamera yakho naku-LCD yekhamera yakho. Ungasebenzisa ukufundwa kwemitha yekhamera yakho ukunquma ukuthi amasethingi wakho wesibhamu osinikiwe mahle yini, noma uma udinga ukwenza noma yiziphi izinguquko.

Hlobo luni lwamamitha akhona?

Izinhlobo zamamitha zingahluka kancane kumikhiqizo yekhamera noma amamodeli wekhamera ngaphakathi kohlobo olufanayo, ngakho-ke thintana nencwajana yekhamera yakho ukuqinisekisa ukuthi iziphi izinhlobo zokulinganisa imodeli yakho enazo. Ngokuvamile, noma kunjalo, amakhamera anokuningi noma konke okulandelayo:

• Ukulinganisa / iMatrix metering. Kule mitha ye-metering, ikhamera ibhekisisa ukukhanya kuyo yonke indawo. Isimo sihlukaniswe igridi noma i-matrix yikhamera. Le modi ilandela iphuzu lokugxila kumakhamera amaningi, futhi iphuzu lokugxila linikezwa okubaluleke kakhulu.
• I-Spot metering. Le mitha ye-metering isebenzisa indawo encane kakhulu ukuya kumitha kusuka. Ku-Canon, indawo yokulinganisa kukhawulwe esikhungweni esingu-1.5% -2.5% sesitholi sokubuka (kuya ngekhamera). Akulandeli iphuzu lokugxila. ENikons, kuyindawo encane kakhulu elandela iphuzu lokugxila kulo. Lokhu kusho ukuthi ikhamera yakho yenza ukufundwa kwemitha yayo kusuka endaweni encane kakhulu futhi ayikunaki ukukhanyisa kuyo yonke indawo yakho.
• Ukulinganisa okuncane. Uma ikhamera yakho inale modi, iyafana namamitha amachashazi, kepha inendawo yokulinganisa enkulu kunaleyo yokubala indawo (ngokwesibonelo, kumakhamera we-Canon, iqukethe cishe i-9% yesitholi sokubuka).
• Isilinganiso esimaphakathi esimaphakathi. Le ndlela ye-metering ibhekela ukukhanyiswa kwesigcawu sonke, kepha ibeka kuqala ukukhanyisa maphakathi nendawo yesehlakalo.

KULUNGILE, ngakho-ke ngizisebenzisa kanjani lezi zinhlobo zamamitha? Zilungele ini?

Umbuzo omuhle! Kulokhu okuthunyelwe kubhulogi, ngizokhuluma ngezinhlobo ezimbili zamamitha engizisebenzisa kahle kakhulu: ukuhlola / i-matrix kanye nebala. Angisho ukuthi ezinye izindlela ezimbili azisizi ngalutho! Ngisanda kuthola ukuthi lezi zindlela ezimbili zisebenza kukho konke engidinga ukukwenza. Ngiyakukhuthaza ukuthi ufunde futhi ufunde kulokhu engizokusho kodwa futhi ngikhuthaza ukuthi uzame ezinye izindlela uma uzizwa ungadinga okuhlukile.

Amamitha wokuhlola / we-matrix:

Le mitha ye-metering iluhlobo lwe- “all-purpose” mode. Yilokho abantu abaningi abakusebenzisa kuphela lapho beqala ukuqala, futhi kulungile. Ukulinganisa amamitha kuhle ukusetshenziswa uma ukukhanya kukhanya ngisho nangasesigcawini, njengakwi-landscape engenakho ukukhanya okungaphezulu noma ukukhanya kwangemuva, futhi kuhle kakhulu ezithombeni eziningi zezemidlalo. Enye indawo lapho imitha yokuhlola ilusizo uma usesimweni lapho uhlanganisa ukukhanya kwe-ambient nokukhanyisa ngaphandle kwekhamera. Ungasebenzisa imitha yokuhlola ukudalula isizinda sakho, bese usebenzisa ilambu lekhamera yakho ukucisha isihloko sakho. Okulandelayo ezinye zezibonelo lapho imitha yokuhlola ilusizo khona.

Owedlule umdwebo wohlobo lomhlaba othathwe ngosuku olumpunga. Ukukhanyisa kwakulingana kakhulu, ngakho-ke amamitha wokuhlola asebenza lapha. Ukulinganisa amamitha nakho kusebenza ezinsukwini ezinelanga ingxenye enkulu, inqobo nje uma ilanga lakho lingaphansi kakhulu empumalanga noma entshonalanga futhi awudubuli ngqo elangeni.

Ngisebenzisa amamitha wokuhlola lapho ngidubula zonke izithombe zami zokushweza, njengale engenhla. Ukulinganisa kwamamitha nakho kuhle kweminye imidlalo efana ne-baseball, ibhola kanye nebhola. Uzodinga ukushintsha amasethingi akho uma ukukhanya kuguquka (njengokuthi ifu liyadlula noma sekuhwalala) ngakho-ke unake imitha yakho esekhamera. Abanye abathwebuli bezithombe bathanda ukudubula imidlalo emvuleni noma kwimodi yokubekwa phambili kwe-shutter, ngakho-ke kuncane okumele ukhathazeke ngakho uma ukukhanya kuguquka.

Kulesi sithombe sokugcina, imitha yokuhlola isetshenziselwe ukuveza kahle izihlahla zangemuva ngenkathi kukhanyiswa ukukhanya kwekhamera kusetshenziselwa ukuveza lezi zithandani.

I-Spot metering:

I-Spot metering yimodi yokulinganisa engiyisebenzisa kakhulu isikhathi. Ngiyisebenzisela ubuningi bemifanekiso yami ekhanyayo yemvelo, kepha isebenziseka kakhulu futhi inokunye ukusetshenziswa. Njengoba ngishilo ngaphambili, i-metering spot isebenzisa ingxenye encane kakhulu yenzwa kumitha. Lokhu kusho ukuthi ungakwazi ukumitha ngokuqondile isihloko sakho ukuze ubadalule kahle, okuhle ezimweni zokukhanyisa ezikhohlisayo. I-Spot metering yilokho ofuna ukukusebenzisa uma udubula ama-backlit shots ngokukhanya kwemvelo futhi awunayo i-flash noma i-reflector. Imitha ebusweni besihloko sakho (ngivamise ukukhipha ingxenye ekhanya kakhulu). Uma udlala ngokuzungeza kwendlu nokulinganisa kwamabala, ungathola izithombe ezinhle kakhulu ezinobuso obukhanyayo nezizinda ezimnyama. Esinye isimo lapho ngithola khona ukuthi amamitha asetshenziswayo anosizo ukuphuma nokushona kwelanga noma ukushona kwelanga. Ngibona imitha ngakwesokunene noma ngakwesobunxele selanga eliphumayo nelishonayo ukuthola izilungiselelo zami. Khumbula ukuthi uma unekhamera yeCanon noma yimuphi omunye umkhiqizo obona amamitha endaweni esethiwe yokubuka indawo kunokulandela iphuzu lokugxila, uzodinga ukumitha usebenzisa indawo ephakathi nendawo yokubuka, bese ubuyisela kabusha, ugcine izilungiselelo zakho, futhi thatha isibhamu sakho.

Njengamanje ungadubula usebenzisa amamitha wokuhlola futhi uzibuze ukuthi yini umehluko uma usebenzisa i-spot metering. Ngezansi kunezibhamu ezimbili, i-SOOC (iqonde ngqo kwikhamera). Ukudutshulwa kwesokunxele kuthathwe kusetshenziswa imitha yokuhlola, lapho ikhamera ifaka khona imitha kusetshenziswa ukukhanyisa kwesigcawu sonke. Isithombe sangakwesokudla sithathwe kusetshenziswa imitha yokubala, kususwa ithanga. Ikhamera icabangela ukukhanya okuvezwa ithanga esithombeni esifanele. Uyawubona umehluko? Okuthengiswayo ukuthi isizinda sakho singashaywa, kepha isihloko sakho ngeke sibe mnyama.

Izibonelo ezimbalwa zezithombe ezisebenzisa i-spot metering:

Umngane wami omncane okhanyayo. Ngabona metered off the bhá ebusweni bakhe.

Bengifuna ukudala ukubukeka kwendlu kulesi sithombe, ngakho-ke ngibone amamitha engxenyeni ekhanyayo yelanga lishona.

Ukulinganisa ama-FAQ's

Ngabe kufanele ngisebenzise ikhamera yami ngemodi yesandla?

Cha! Ungasebenzisa amamitha ekuvulekeni nasezimodeni ezibalulekile ze-shutter, futhi. Uzodinga nje ukusebenzisa isici sokukhiya se-AE (autoexposure) ukukhiya izilungiselelo zakho uma udinga ukwenza kabusha isibhamu sakho. Amamitha wakho wekhamera kuzo zonke izindlela, noma i-auto, kepha kumamodi wokuzenzakalela, ikhamera yakho ikhetha amasethingi ngokuya ngamamitha kunokuba ukwazi ukukhetha noma ukukhohlisa izilungiselelo.

Ikhamera yami ayinayo i-metering spot. Ngisengakwazi ukuthatha izithombe ezingemuva?

Kunjalo. Kunamamodeli athile wekhamera angahle angabi namamitha amachashazi kepha anemitha elilinganiselwe. Kulawo amamodeli, sebenzisa amamitha ayingxenye yemiphumela efanayo. Ungadinga ukudlala uzungeze kancane ukuze ubone ukuthi yini okusebenzela kangcono ikhamera yakho.

Imitha yekhamera yami ikhombisa ukuvezwa okulungile, kepha isithombe sami sibukeka simnyama kakhulu / sikhanya kakhulu.

Njengoba kushiwo ekuqaleni kwalokhu okuthunyelwe, amamitha wokukhombisa awaphelele, kepha asondele. Into ebaluleke kakhulu uma udubula ukubheka i-histogram yakho ukuze uqiniseke ukuthi ukutholakala kwakho kuhle. Uzofunda ukuthi ikhamera yakho iziphatha kanjani ezimweni ezahlukahlukene ngemuva kwesikhashana (ngokwesibonelo, ngidubula okungenani i-1/3 yokuma okuvezwe kakhulu kuwo wonke ama-Canon ami, futhi lokho kungakhuphuka ngokuya ngesimo). Uma udubula ngemodi yesandla, ungakhetha ukwandisa noma ukunciphisa ukuvula kwakho, isivinini se-shutter, noma i-ISO ngokuya ngemiphumela oyitholayo. Uma udubula uvula imodi yokuvula noma yokushutha, ungasebenzisa isinxephezelo sokuchayeka ukuze uveze ukuvezwa kwakho.
