Makamera ambiri atsopano a digito ali ndi chidziwitso chochuluka kwa oyambirira ojambula kupanga zojambula zazikulu , zomwe zikutanthawuza kuti kuthetsa kwakukulu mu kamera ya digito sikofunikira monga kale. Mwa kuyankhula kwina, makamera atsopano a digito akhoza kuwombera zomwe zimaonedwa kuti ndizithunzi zapamwamba.
Kumbukirani, komabe, zithunzi mu kamera yadijito sizipatsidwa ma labels monga HD (kutanthauzira kwapamwamba) kapena ma HD, monga momwe mungapeze pamene mafilimu akuwombera ndi kamera ya digito kapena digito yamakina kapena pamene akuonera TV. Kotero inu mukhoza kukhala wosokoneza kukonza kwapamwamba ndi kutanthauzira kwakukulu pamene mukufunsa funso ili.
Chifukwa palibe chiwerengero cha "chithunzi" cha chithunzi chapamwamba kwambiri, kutsimikiza chomwe chikuganiziridwa kukhala chosamalitsa chidzakhala chosiyana ndi wojambula zithunzi wojambula zithunzi. Kumbukirani kuti kumayambiriro kwa khumi khumi, ma megapixels 10 a chiwonetsero chazithunzi ankaonedwa kuti ndi ochuluka ndipo mwina amalingalira kuti ali ndi kuthetsa kwakukulu.
Osatinso pano. Tsopano, ngakhale makamera apamwamba kwambiri a digito, monga makamera opambana pansi pa $ 200 , nthawi zambiri amapereka ma megapixels 20 a kuthetsa. Ndipo DSLRs yapamwamba imatha kupatsa majegixix 36 kapena ndondomeko yambiri, monga Nikon D810 . Chithunzi cha zomwe zimaonedwa kuti ndizithunzi zapamwamba zidzasintha ngati teknoloji ya kamera ikukula m'tsogolomu.
Kumvetsa Megapixels
Tisanayambe kupita patsogolo, tiyenera kufotokoza momwe timagetsi timagwirira ntchito pa makamera. Masegapixel amodzi ali ofanana ndi pixel 1 miliyoni. Pixel ndi malo amodzi kwambiri pachithunzi cha fano chomwe chimayesa kuchuluka kwa kuwala komwe kumayenda kudzera mu lensera ya kamera ndi kuigunda. Chithunzi chojambula chimagwirizanitsa mapilisi onse omwe chithunzi chojambula chikhoza kuyeza. Kotero chojambula chojambula chomwe chiri ndi maipipikiselini 20 chidzakhala ndi malo 20 miliyoni payekha momwe zingathe kuyesa kuwala.
Zina Zofunika Kuziganizira
Ngakhale kuti kuthetsa malingaliro kuli kofunikira pozindikira khalidwe la zithunzi ndi zithunzi zowonongeka, kumbukirani kuti makamera onse a digito a chisankho chinachake sangawononge khalidwe lomwelo. Mtengo wamatenda, khalidwe lachithunzi cha zithunzi, komanso nthawi yamagetsi ya kamera zonse zimakhudza khalidwe lazithunzi, nayenso.
Kuchuluka kwa chisankho chomwe mukufuna DSLR kapena mfundo yanu ndi kuwombera kamera kumadalira mmene mukukonzera kugwiritsa ntchito zithunzi. Zojambula zazikulu zimafuna kuthetsa zambiri ngati mukufuna kuti mapepalawa akhale okhwima komanso omveka ngati n'kotheka. Kwa mafano okhala ndi chisankho chochuluka, mukhoza kuchepetsa chithunzi ndikusindikizira pa kukula kwakukulu popanda kutaya tsatanetsatane mukusindikiza.
Pokhapokha ngati muli wojambula zithunzi, n'zovuta kulingalira kuti makamera ambiri alibe chidziwitso chokwanira cha kuwombera zomwe zingatengedwe kukhala zithunzi zowonongeka kwambiri. Mukhoza kupanga zojambula zazikulu kwambiri ndi ma megapixels 10 okha pokhapokha chithunzi chikuwonetsedwa molondola ndipo chikuwunika kwambiri
Kujambula Chithunzi chachikulu
M'malo modandaula za momwe mungathere kukonza chithunzi, onetsetsani kuti mukuwombera ndi kuwonetsa bwino ndikuwunika bwino kuti muwonetse khalidwe labwino la chithunzi. Mudzasangalala kwambiri ndi kujambula kwanu zotsatira ngati mutenga nthawi yokhala ndi phunziro lalikulu, zolemba bwino, zolingalira zolondola, ndi kuwonetsa bwino, m'malo modandaula kwambiri ngati padzakhala chithunzi chabwino kwambiri.
Ndikofunika kumvetsetsa kuti kamera yokhala ndi chithunzi chachikulu chidzapanga chithunzi chapamwamba kuposa kamera yokhala ndi chithunzi chachikulu, ngakhale makamera atapereka chiwerengero chomwecho. Choncho chiwerengero ndi ziwerengero za megapixel sizinthu zokha zomwe zimamvetsera pamene mukuyesera kuti muone ngati mukuwombera chomwe chingawonedwe ngati chithunzi chapamwamba.
Pezani mayankho ena ku mafunso a kamera wamba pamasamba a mafunso a kamera.
