Ukuboniswa - sisixa ukukhanya CCD

Le khamera kumgaqo yesenzo embhoxo kwamehlo a ophilayo. Enyanisweni, sibona izinto kokusingqongileyo njengoko zinjalo, ngenxa yokukhanya iboniswe eziwela retina. Ngokufanayo, ukuba usebenza nayiphi camera. Ukukhanya kubonakala ukusuka into iwela ilungu photosensitive - bhanyabhanya okanye matrix digital, ihlabe umfanekiso fingerprint ifunyenwe.

Ukuboniswa - oku ubungakanani bokukhanya ezifunyenwe yekhamera matrix. umfanekiso Overexposed uya kukhangela eliqaqambileyo kakhulu, underexposed - mnyama. Ngokufanayo, iliso yabantu ulungise ukwandisa okanye ukunciphisa ukhanyiso, icamera lingamiselwa phantsi kweemeko ezithile zokusingqongileyo. Ukuze ufumane ifoto oqhelekileyo, oko ngokucacileyo zonke iinkcukacha, icamera kufuneka alungise ngokufanelekileyo - ukunciphisa okanye ukwandisa emngxunyeni lens okanye shutter Isantya.

Ngoko ke, eneneni, ukuba sesichengeni echanekileyo - kukuthi, ngaphezu kwabo bonke, ukukwazi ukuqwalasela ikhamera ukuze isithombe evumelanayo ngokumalunga indibanisela izithunzi kunye nokukhanya. Umzekelo, ukuba semnyameni wagqiba ukwandisa yomgodi lens kukufumana umfanekiso ecacileyo, kuza kufuneka ukuba ukunciphisa exposure, okt ixesha shutter.

Kukho into enje ibe sesichengeni kabini. Kule ifoto enyanzeliswa phezu ingongoma ukujonga imifanekiso emibini. Olu hlobo amaninzi kusetyenziswa kufota lobugcisa ukwenza imifanekiso yokuqala. Image nangokuvela kabini ikhangeleka ngathi isitalato kwikroba iglasi okubonisa nempahla. Le ndlela umdla kakhulu, ngokufuthi ezisetyenziswa abafoti abaqeqeshiweyo.

technology yedijithali Modern kuvumela ukwenza lula kakhulu umsebenzi inkosi. Ngenxa yokuba sesichengeni - akukho nto ngaphezu iqondo ubukho kwi ifoto izithunzi kunye iimbalasane kwi fomati yomfanekiso RAV kube lula kakhulu ukuba ukulungisa qualitative kakhulu ngokubhekiselele umfanekiso sesichengeni emva ukudubula. Cameras ziyafumaneka, nto leyo inomsebenzisi ekuvumela ukuba wenze oku lula. Ngapha koko, umphumo efanayo aokusetyenziswa kusetyenziswa iintlobo lweenkqubo zekhompyutha, lowo uthandwayo yona Photoshop.

Exposure kufota kubaluleke kakhulu. Ixabiso bezobugcisa mfanekiso kuxhomekeke kuphela xa umboniso ezikhethiweyo kakuhle, kodwa ke ingcaciso yomfanekiso ukubonwa yaye zonke iinxalenye zayo. Ngoko ke, nayiphi na umfoti kufuneka akwazi ukuqwalasela kakuhle ikhamera nokusebenza kunye nomfanekiso ekujoliswe kulo kwi computer. iikhamera Modern, nokuba digital, ukulungiselela ukuphunyezwa a iifoto ezintle ecacileyo lonke ithuba.

Ngokufuthi, ukongeza scheme umbala echanekileyo, i-exposure - le nto imisela umgangatho efotweni. Nokuba ukuba andilociko okhawulezayo oqhelekileyo for the album usapho, ifoto kufuneka ibe akukho overexposed okanye underexposed. Oku kungafezekiswa, ukuba usebenzisa i iikhamera mihla eziqhelekileyo digital.
