Niaj hnub no, yuav luag txhua tus ntawm peb muaj qhov zoo li lub koob yees duab - tsawg kawg hauv xov tooj. Ua tsaug rau cov txheej txheem no, peb tuaj yeem siv ntau pua daim duab thiab cov duab sib txawv yam tsis siv dag zog ntau. Tab sis tsawg tus neeg paub tias ib qho ntawm qhov tseem ceeb uas tuaj yeem cuam tshuam rau qhov zoo ntawm daim duab yog qhov nkag siab rau lub teeb hauv lub cuab yeej yees duab. Cia peb sim nkag siab lub luag haujlwm ntawm cov yam ntxwv zoo li ISO, qhov ntsuas no txhais li cas thiab yuav xaiv nws li cas.

Nws yog dab tsi?

Dab tsi yog qhov rhiab ntawm lub koob yees duab digital? Qhov no yog tus yam ntxwv uas ua rau nws muaj peev xwm txiav txim siab qhov kev vam khom ntawm cov lej ntawm cov hom duab uas tsim los ntawm lub koob yees duab ntawm qhov raug, uas tau txais los ntawm cov duab zoo nkauj. Txhawm rau muab nws yooj yim me ntsis, qhov no yog qhov taw qhia ntau npaum li cas lub matrix pom qhov khiav ntawm lub teeb. ISO cuam tshuam rau kev nkag siab ntawm lub cuab yeej rau cov teeb pom kev zoo . Yog tias xav tau, koj tuaj yeem ua haujlwm yooj yim hauv qhov chaw tsis muaj teeb pom kev zoo, lossis, sib tham, tua hauv chav tsaus ntuj lossis yav tsaus ntuj, thaum muaj teeb pom kev tsawg heev. Thaum tseem tsis muaj cov thev naus laus zis thev naus laus zis rau kev tua, qhov ntsuas no tau hais tshwj xeeb rau zaj duab xis. Tab sis tam sim no lawv ntsuas nws rau lub tshuab hluav taws xob.

Feem ntau, qhov ntxim nyiam ntawm lub hauv paus rau qhov ntws ntawm lub teeb yog qhov ntsuas tseem ceeb heev ntawm kev yees duab . Nws yuav yog lub hauv paus tseem ceeb thaum kho kho qhov tshwm sim tom qab, lossis ntau dua, kaw qhov nrawm thiab qhov siab. Qee zaum nws hloov tawm tias cov yam ntxwv ntawm qhov ntsuas tau txiav txim siab raug, thiab nws zoo li tias cov lus pom zoo tsim nyog tau ua raws, tab sis lub teeb pom kev tsis tuaj yeem ua tiav. Thiab qee qhov xwm txheej daim duab tsaus heev, thiab hauv lwm tus nws lub teeb dhau.

Yog li ntawd, teeb tsa ISO yuav tsum tsis txhob raug tso tseg, vim tias ua tsaug rau nws koj tuaj yeem kho qhov tsim nyog ua kom pom qhov sib luag, uas yuav ua rau pom qhov tshwm sim ntawm tus qauv yav tom ntej yam tsis siv lub teeb nyem.

Yuav xaiv li cas?

Tom qab peb xam tawm qhov xwm txheej hauv nqe lus nug yog lub luag haujlwm, nws yuav tsis yog qhov xav tau los txiav txim siab yuav xaiv nws li cas thiaj li tua tau qhov zoo tshaj plaws thiab yooj yim tshaj plaws. Txhawm rau xaiv txoj cai ISO hauv lub koob yees duab, koj yuav tsum nug koj tus kheej li 4 lo lus nug ua ntej qhov no:

• nws puas tuaj yeem siv lub tripod;
• seb lub ntsiab lus puas tau teeb pom kev zoo;
• seb qhov kev kawm txav mus los yog nyob hauv qhov chaw;
• seb koj puas xav tau cov duab grainy lossis tsis.

Yog tias qhov kev txaus siab tau teeb pom kev zoo, lossis yog tias koj xav kom txo cov qoob loo kom ntau li ntau tau, koj yuav tsum siv lub tswb lossis lub lens hom tsau. Hauv qhov no, koj yuav tsum teeb tsa tus nqi qis ISO.

Yog tias kev tua raug nqa tawm hauv qhov chaw tsaus lossis hauv lub teeb qis, thiab tsis muaj lub koob yees duab ntawm tes thiab cov ntsiab lus nyob hauv kev txav, tom qab ntawd kev saib xyuas yuav tsum tau ua kom nce ISO . Qhov no yuav ua rau nws muaj peev xwm thaij duab tau nrawm dua thiab muaj qhov raug zoo. Txawm li cas los xij, vim qhov nce hauv lub suab nrov hauv cov thav duab, nws yuav dhau los ua qhov pom kev loj dua.

Yog tias peb tham txog cov xwm txheej uas nws yuav tsim nyog los nce ISO kom tau txais cov duab zoo dua, lawv tuaj yeem ua raws li hauv qab no

1. Ntau yam kev sib tw ncaws pob uas cov khoom txav mus nrawm heev thiab cov teeb pom kev feem ntau txwv.
2. Ua yeeb yaj kiab hauv cov tsev teev ntuj thiab kos duab kos duab. Feem ntau hauv cov xwm txheej no nws tsis tuaj yeem siv lub teeb nyem rau ntau qhov laj thawj, thaj chaw zoo li no feem ntau tsis pom kev zoo.
3. Kev hais kwv txhiaj uas tshwm sim nrog qhov tsis pom kev zoo tshaj plaws. Thiab nyem rau ntawm lawv kuj tsis ua haujlwm.
4. Ntau yam kev ua ub no. Wb hais hnub yug. Piv txwv li, thaum tus tub hnub yug tshuab rau taws tswm ciab hauv chav tsaus, siv lub teeb nyem tuaj yeem ua rau puas tsuaj. Tab sis yog tias koj nce ISO, tom qab ntawd qhov xwm txheej tuaj yeem raug ntes kom ntxaws.

Cia peb ntxiv tias ISO yuav yog ib qho tseem ceeb heev ntawm kev yees duab digital . Koj yuav tsum paub txog nws thiab nkag siab nws qhov chaw yog tias muaj lub siab xav tau cov duab zoo tiag tiag. Thiab txoj hauv kev zoo tshaj kom paub ISO yog sim nrog ntau yam kev teeb tsa. Qhov no yuav ua rau nws nkag siab tias lawv cuam tshuam li cas rau daim duab kawg. Tsis tas li ntawd, koj yuav tsum paub cov ntaub ntawv siab tshaj plaws txog aperture, ceev ceev , vim tias lawv cov txiaj ntsig ntawm ISO tam sim ntawd.

Kev kho

Kev hloov kho tus yam ntxwv hauv nqe lus nug yog xav tau txhua lub sijhawm ua qhov kev tshawb fawb tshiab . Lawm, peb tab tom tham txog qhov tseeb tias koj tsis tau tua hauv chav yees duab, qhov twg txhua qhov tsim nyog teeb pom kev zoo twb tau teeb tsa, uas koj tau ua haujlwm ntau zaus lawm. Yog tias koj xav khaws cov duab zoo, tom qab ntawd nws zoo dua tsis txhob sim nrog tus yam ntxwv no.

Nyob rau tib lub sijhawm, yog tias cov txheej txheem tua hluav taws xav tau nws, koj tuaj yeem teeb tsa qhov xav tau qhov ntsuas lub teeb nyob hauv lub koob yees duab, tab sis nws yog qhov zoo dua los ua qee qhov kev sim ua ntej txhawm rau txhawm rau pom qhov siab tshaj plaws ISO tus nqi thiab tua zoo.

Hauv feem ntau ntawm cov xwm txheej, nws zoo dua kom tau txais cov duab me me los yog tsaus dua ntawm qhov ua tau zoo, qhov tsis zoo ntawm qhov uas tuaj yeem kho tau hauv qee qhov kho duab duab, dua li tom qab ua haujlwm ntev kom pom qee qhov me me-hom ntas, uas tseem yuav yuav tsum paub qhov txawv ntawm qhov muaj cov pawg ntawm cuam tshuam thiab suab nrov.

Feem ntau, muaj qee qhov kev xaiv rau kev kho lub teeb pom kev zoo hauv cov cuab yeej siv yees duab, tab sis cia peb tham txog qhov feem ntau. Ua ntej koj yuav tsum tso phau ntawv hloov kho ntawm cov yam ntxwv ISO . Tom qab ntawd, koj yuav tsum ua hloov ntawm hom pib mus rau hom hom "M ", uas yuav muab sijhawm ntau ntxiv rau teeb tsa qhov txiaj ntsig xav tau.

Koj kuj yuav tsum saib hom ntawm hom "A", uas yog, qhov chaw teeb, "S ", uas yog lub luag haujlwm rau cov yam ntxwv laus, ib yam " Peb ", uas yog lub luag haujlwm rau qhov pib kho ntawm hom ntse. Thaum siv cov khoom siv tsom iav, koj yuav tsum tau siv cov ntawv qhia zaub mov los ntawm txhaj rau Cov khoom "ISO teeb tsa " … Ntawm no koj yuav tsum txiav txim siab tus nqi xav tau, thiab tom qab ntawd teeb tsa cov khoom "Auto ". Cov cuab yeej siv yees duab zoo tshaj plaws feem ntau yog nruab nrog tus yuam sij tshwj xeeb, uas tuaj yeem nyob ntawm ob sab saum toj thiab sab ntawm lub cuab yeej, uas yog lub luag haujlwm rau "ntse" teeb tsa feem ntau ntawm cov yam ntxwv ib zaug.

Ib qho ntxiv, ib tus yuav tsum tsis txhob hnov qab txog ib qho tseem ceeb nthuav dav, uas rau qee qhov laj thawj uas ntau tus neeg siv tsis quav ntsej. Lub ntsiab lus yog tias daim duab matrix yog lub hauv paus tseem ceeb hauv kev ntaus ntawv.

Yog li ntawd, yam tsawg kawg ntawm lub sijhawm, nws yuav tsum tau muab ntxuav thiab so nrog qhov tshwj xeeb degreaser . Qhov no ua rau nws tuaj yeem zam kev tsim cov kab txaij ntawm lub koob yees duab thiab ntau yam xim uas tuaj yeem tsim los ntawm villi lossis cov av me me ntawm cov av uas yuav nyob ntawm qhov matrix nto. Koj tuaj yeem ua tus txheej txheem no ntawm koj tus kheej thiab hauv tsev, yog tias koj xub tau txais cov khoom siv tshwj xeeb tu. Tab sis yog tias koj yog tus pib, tom qab ntawd nws yuav zoo dua los tso txoj cai no rau tus kws tshaj lij.

Lub tswv yim pab tau

Yog tias peb tham txog cov lus qhia muaj txiaj ntsig, tom qab ntawd kuv xav sau qee qhov kev qhia me me uas yuav tso cai rau koj kom thaij duab tau zoo dua. Ua ntej, cia peb hais qhov ntawd thaum siv flash thiab auto-ISO, nws yog qhov zoo dua los ua qhov kev xaiv tom kawg . Qee lub sij hawm lub koob yees duab tsuas yog tua tsis raug los ntawm kev sib raug zoo thiab qhov twg nws tuaj yeem txo qis ISO, lub koob yees duab cia li teeb tsa nws mus rau qhov siab tshaj plaws thiab tseem siv cov duab nrog nyem. Yog tias lub cuab yeej muaj lub teeb nyem, tom qab ntawd koj tuaj yeem teeb tsa tus nqi yam tsawg kawg ntawm tus yam ntxwv hauv nqe lus nug.

Lub ntsiab lus tom ntej uas tuaj yeem pab ua kom tua tau zoo dua - ntawm qee tus qauv ntawm cov koob yees duab SLR, thaum teeb tsa ISO pib hauv cov ntawv qhia zaub mov, koj tuaj yeem teeb tsa ib qho siab tshaj los yog yam tsawg kawg nkaus nws qhov taw qhia Qee zaum, txhawm rau xaiv tus nqi me tshaj, koj yuav tsum tso tus lej tsis raug. Piv txwv li, 800. Thiab tom qab ntawd ntau kawg ntawm 1600 peb tau txais ntau yam ntawm ISO 800-1600 hom, uas yog, tus nqi no tsis tuaj yeem qis dua. Thiab qee zaum qhov no yog qhov muaj txiaj ntsig zoo.

Thiab ib qho tseem ceeb ntxiv uas cov kws yees duab hu " Txoj cai kub ntawm ISO kho. " Thiab nws dag nyob rau hauv qhov tseeb tias nws yog qhov yuav tsum tau ua qhov kev soj ntsuam tsuas yog ntawm qhov tsawg kawg nkaus qhov tseem ceeb. Yog tias muaj lub sijhawm los txo tus lej, qhov no yuav tsum ua. Thiab kom nqa tsuas yog thaum tsis muaj nws hauv txhua txoj kev. Txhawm rau kom tus yam ntxwv piav qhia kom tsawg li ntau tau, koj yuav tsum qhib lub diaphragm kom tiav . Thiab yog tias koj siv flash, koj yuav tsum tsis txhob siv ISO siab tshaj plaws. Feem ntau, peb yuav hais tias tsis yog txhua tus tuaj yeem siv cov lus piav qhia. Tab sis yog tias koj nkag siab nws thiab nkag siab tias nws cuam tshuam li cas rau kev tua, koj tuaj yeem nthuav dav lub peev xwm ntawm koj lub koob yees duab thiab tau txais cov duab zoo dua thiab meej dua vim yog siv qhov ntsuas no raug.
