Yintoni exposure? Kwezinye iimeko, kusetyenziswa lo msebenzi, yaye nokuba oko kuyimfuneko camera?

iifoto ophezulu ezikumgangatho ayikwazi ingafumaneka kwimo oluzenzekelayo kunye nezicwangciso emiselweyo. Kakade ke, ukuba babe yinto enobukhazikhazi umdla kwisangqa oluthile lwabantu, kodwa umsebenzi wobugcisa ukubabiza nzima.

Loo umsebenzi a njenge yekhamera, efunekayo xa uhambisa izifundo, ecacileyo, kabukhali, okanye icala, lo iimvakatjhi izinto ezithile (umz, amanzi).

Ngoko ke, yintoni na sesichengeni? Ukusuka kwindawo yezobugcisa imbono - kukho ixesha apho kudlule kwimitha ukukhanya yi emngxunyeni lens, esiwa kwilungu photosensitive.

Ukusuka apho umbono lwenzululwazi, siye sachaza ukuba sesichengeni ezinjalo. Kaloku ke, yenza ngokweenkcukacha ntoni na nendlela ukuphumeza nezo ziphumo zinqwenelekayo.

Le parameter ibalwa kwimizuzwana: 1 / 30sec, 1 / 60sec. Amaxesha amaninzi, ezi iziboniso ikhamera kuphela elingezantsi, musa ukoyika njalo. Lekhamera compact inani kuboniswa ngolu hlobo lulandelayo: 1.1 / 2, ¼, 1/8, njalo-njalo.

Kuyo nayiphi na izixhobo nokufotwa ngumsebenzi njengoko shutter ephambili. Oku kuthetha ukuba inyenyisa ngokuzenzekelayo umngxuma yokukhetha.

speed shutter Fast

Ngoku uyazi ukuba isantya shutter. Cinga iimeko ezisebenzisa lamanani ngasentla? Ngoko nangoko, siphawula ukuba sesichengeni mfutshane eyenzelwe izilwanyana ukudubula, imidyarho, ezemidlalo, ukuba kukho into ehamba kwifoto ayikhangeleki "kufiphale". I ngokukhawuleza senza into, i ezincinane amisiweyo parameter. Kodwa khumbula, kulo mzekelo, udinga ukukhanya okufanelekileyo, ngokuba isango ufumana ukukhanya ngaphantsi. Ukulungisa le meko iya kunceda uvalo, iqondo ngazo ukwandisa ngooceba abanyulwe ukuba sesichengeni ukuhla.

Isantya Slow shutter

Sebenzisa oku nokuzibonakalisa zokukhanya kunye neziphumo ezizodwa. Kodwa apha, qiniseka ukuba usebenzisa i enemilenze emithathu, kungenjalo kweso phezu kumfanekiso yonke. Ukuba umise uvakalelo oluphezulu, emva koko lindela yokuba ebumnyameni kwifoto ubotshiwe ukuba "ingxolo". Ungalungisa oku kule nkqubo "Photoshop", kodwa umgangatho nto lifinyele.

Exposure ubukhulu kubaluleke ngokukodwa xa zokudubula amanzi, akukhathaliseki nokuba lithende okanye umlambo. Too shutter ngesantya ukudala ifuthe kwindawo tyaba, yaye ixesha elide - nokungabikho kabukhali. Ngoko, kuba imilambo ezicothayo nemilambo ngomlinganiselo we ukususela 1/30 ukuya ku-1 / 125c. Xa imozulu ezinomoya, beka setting ukususela 1/125 ukuya 1/250. Imilambo kufuneka isuswe ngamaxabiso emalunga nesi-1/1000.

Ukuba une ngokwaneleyo ezikumgangatho ophezulu SLR khamera okanye umsebenzi, uyakwazi ukususa ubuhle ngobusuku zezulu ulibele iiyure eziliqela. Ngoko ke ufumana i ifoto umdla nje kuphela, kodwa isikhokelo Yomhlaba. Musa ukulibala malunga ubuntununtunu, okanye ingxolo kunokuba nodandatheko.

Xa ngokudubula ukusetyenziswa kwamanzi ngesantya ngokukhawuleza shutter ukuba akukho ngaphezulu kwe-1/30, ngenxa yokuba sasingahlali ndawonye, nto leyo ithetha ukuba kungenzeka ukufumana umfanekiso imfiliba.

Ngoku icace usebenza ntoni isantya kwaye yintoni amatyala. Ukuba oyifunayo, iziphumo umdla zingafumaneka nkqu iikhamera compact phambili, kodwa ukuba nithetha izixhobo zobungcali, kukho ilungiselelwa yobuciko. Cinga iimpawu zeemeko zakho lwekhamera nokudubula, nkqu libalele okanye namafu utshintsho kakhulu isiphumo.
