Kaya akuyesa chikalata kapena kusankha kamera ya digito, anthu ambiri amasokonezeka ndi ma pixel angati amene amawafuna mu fano. Ndipotu, makamera ambiri a SLR amajambula zithunzi pamasulidwe a ma pixelisi 300 pa inchi yomwe ili yabwino kwa fano yokonzekera makina osindikizira. Komabe, pali kuganizira kwambiri za chisankho makamaka pankhani ya makamera ndi makina osindikiza.
Choyamba, ndikofunikira kumvetsetsa mawu ochepa omwe akugwirizana ndi kukula ndi kusinthika kwa zithunzi - PPI, DPI, ndi Megapixels. Ngati simukudziwa bwino mawuwa, kapena mukufuna kuwatsitsimutsa, tsatirani zowonjezera pansipa kuti mudziwe zambiri:
Ma pixels pa inchi (ppi) - Mndandanda wa chiwonetsero cha chithunzi chomwe chimatanthawuza kukula kwake chithunzi chidzasindikizidwa. Zokwera mtengo wa ppi, ubwino wosindikizira womwe udzalandira - koma pokhapokha. 300ppi kawirikawiri amalingaliridwa kuti ndilo kuchepetsa kubwezeretsa kubwera kwa ink jet yosindikiza zithunzi.
Machaputala ndi inche (dpi) - Mndandanda wa chisankho chosindikizira chomwe chimatanthauzira ma dothi angati ayikidwa patsamba pamene chithunzi chikusindikizidwa. Masiku ano makina osindikizira a ink jet ali ndi zithunzi zambirimbiri (1200 mpaka 4800 dpi) ndipo amakupatsani zithunzi zovomerezeka zojambula zithunzi ndi 140-200 ppi kukonza, ndi mapangidwe apamwamba a zithunzi ndi 200-300 resolution ppi.
Megapixels (MP) - pixel milioni imodzi, ngakhale kuti nambalayi nthawi zambiri imakhala yozungulira pofotokoza kukonza kamera kamera.
Podziwa kuti ndi ma pixel angati omwe mukufunikira, zonsezi zimaphika momwe mungagwiritsire ntchito chithunzicho komanso kukula kwake ndi kusindikiza kwake. Pano pali tchati lothandizira kuti mutsogolere pozindikira momwe mungakwaniritsire ma pixel angapo kuti musindikize zithunzi zowonjezera zazikulu pa printer ya jinjeni kapena kudzera mu utumiki wosindikizira pa intaneti.
5 MP = 2592 x 1944 pixels
Mwamba: 10 × 13 mainchesi
Chikhalidwe Chovomerezeka: 13 × 19 mainchesi
4 MP = 2272 x 1704 pixels
Mapamwamba: 9 × 12 mainchesi
Mphamvu yovomerezeka: 12 x 16 mainchesi
3 MP = 2048 x 1536 pixels
Mwamba: 8 × 10 mainchesi
Mphamvu yovomerezeka: 10 x 13 mainchesi
2 MP = pixels 1600 x 1200
Mwamba: 4 × 6 mainchesi, 5 × 7 mainchesi
Mphamvu yovomerezeka: 8 × 10 mainchesi
Pansi pa 2 MP
Ndizoyenera zokhazokha pazithunzi kapena zojambula zapalake. Onani: Ndili ndi pixel zingati zomwe ndikufunikira kuti ndigawane zithunzi pa intaneti?
Ndiposa ma megapixels asanu
Mukapitirira maegapixels asanu, mwayi ndiwe wojambula zithunzi wodziwa kugwiritsa ntchito zipangizo zam'mwamba, ndipo muyenera kukhala nawo kale pamaganizo a kukula kwa zithunzi ndi chisankho.
Madontho a Megapixel
Opanga makamera a digitala angafune makasitomala onse kuti akhulupirire kuti ma-megapixels apamwamba amakhala abwino koposa, koma monga momwe mungathe kuwonera pa tchati pamwambapa, pokhapokha mutakhala ndi printer yaikulu ya jet jet, chirichonse choposa mamitaiiiiii apamwamba kuposa momwe anthu ambiri adzafunira.
Komabe, pali nthawi pamene ma megapixels apamwamba angathe kubwera moyenera. Mafilimu apamwamba angapangitse ojambula ojambula kukhala ndi ufulu wokolola kwambiri pamene sangathe kukhala pafupi ndi phunziro monga momwe angafunire. Koma malonda opita kumapapixelita apamwamba ndi mafayela akuluakulu omwe angafune malo ochulukira mukumakono kamera yanu ndi disk malo osungirako pa kompyuta yanu. Ndikumva kuti mtengo wa zosungirako zina ndizofunika kwambiri, makamaka pa nthawi yomwe mumatenga chithunzi chopanda phindu ndipo mungafune kusindikizira mokweza kwambiri. Kumbukirani, nthawi zonse mungagwiritse ntchito ntchito yosindikizira pa intaneti ngati chosindikiza chanu sichikhoza kusamalira mtundu waukulu.
Mawu Ochenjeza
Pali zambiri zomwe zikufotokozedwa apa koma ndizofunikira kuti muzindikire kuti simukuwonjezera ppi mtengo wa chithunzi ku Photoshop. pofikira Zithunzi> Kukula kwa Zithunzi ndi kuwonjezera mtengo wapatali.
Chinthu choyamba chomwe chidzachitike ndi kukula kwa mafayilo ndi mapangidwe a zithunzi kudzakhala ndikuwonjezeka kwakukulu chifukwa cha ma piselipi ambiri omwe adawonjezeredwa ku chithunzichi. Vuto ndi maonekedwe a mtundu wa ma pixels atsopanowa, mwabwino, "kulingalira bwino" pambali ya kompyuta chifukwa cha ndondomeko ya mapolisi. Ngati chithunzi chili ndi chiganizo zosachepera 200 ppi kapena zosachepera, siziyenera kugwedezedwa.
Onaninso: Ndingasinthe bwanji kukula kwa chithunzi cha digito?
