Lapho udubula izithombe ngekhamera yakho yedijithali , ungasetha ikhamera ukudubula kwisinqumo sekhamera eklanyelwe ukuhlangabezana nezidingo zakho. Ngokukhetha okuningi, kungaba nzima ukuphendula umbuzo: Ngisidinga isiphi isinqumo sekhamera?
Ngezithombe ohlela ukuyisebenzisa kuphela kwi-Inthanethi noma ukuthumela nge-imeyli, ungadubula ngesinqumo esincane. Uma wazi ukuthi ufuna ukuphrinta isithombe, uzodinga ukudubula ngesinqumo esiphezulu .
Kodwa-ke, uma ungaqiniseki ukuthi uhlela kanjani ukusebenzisa isithombe, iseluleko esingcono kakhulu esilandelayo nje ukudubula izithombe ngesinqumo esiphezulu ositholile ngekhamera yakho. Ngisho noma ekuqaleni ungafuni ukuphrinta isithombe, ungase uthathe isinqumo sokwenza ukuphrinta izinyanga eziyisithupha noma unyaka phansi komgwaqo, ngakho ukudubula iningi lezithombe zakho ngesinqumo esiphezulu cishe ngaso sonke isikhathi yisinqumo esingcono kakhulu.
Enye inzuzo yokudubula esinqumweni esiphezulu kunazo zonke ungakwazi kamuva ukutshala isithombe kwisayizi encane ngaphandle kokulahlekelwa imininingwane kanye nekhwalithi yesithombe.
Ukukhetha i-Right Camera Resolution
Ukunquma ukuxazulula ukhamera kwekhamera ukuthi ekugcineni uzodinga ukuphrinta kuxhomeke kubukhulu bokuphrinta ofuna ukukwenza. Itafula elibalwe ngezansi kufanele likusize unqume ngesinqumo esifanele.
Ngaphambi kokubheka ukuthi inani lokuxazulula izixazululo lihlobene kanjani namasayizi wokuphrinta ama-photo, noma kunjalo, kufanelekile ukugcina engqondweni ukuthi ukuxazulula akuyona kuphela into ekhwalithi yesithombe kanye nekhwalithi yokuphrinta.
Lezi zici nazo zidlala indima ebalulekile ekunqumeni ukuthi izithombe zakho zedijithali zizobukeka kanjani kwikhompyutha nakwephepha.
- Ukukhanyisa okufanele
- Ikhwalithi ye-lens
- Ukuzinza kwekhamera
- Ukugxila ngokuzenzakalelayo esihlokweni esifanele
- Isivinini esifanele se-shutter sokuhamba noma okumilayo
- Imishini ehlanzekile
Esinye isici esenza indima ebalulekile emgangathweni wezithombe - okuyinto ezokwenza ukuthi inkulu kangakanani ongayenza ukuphrinta - iyinzwa yesithombe sekhamera .
Njengomthetho ojwayelekile, ikhamera ene-image enkulu enziwe ngobukhulu obungokwenyama ingakha izithombe eziphezulu zekhwalithi ngokumelene nekhamera enenzwa yesithombe encane, kungakhathaliseki ukuthi zingaki ama- megapixels wokuxazulula ukunikezwa kwekhamera ngayinye.
Ukunquma ubukhulu bezinhlamvu ozofuna ukuzenza nakho kungakusiza lapho uthengisa ikhamera yedijithali . Uma wazi ukuthi uzofuna ukwenza ama-prints amakhulu sonke isikhathi, uzodinga ukuthenga imodeli enikezela isinqumo esikhulu esiphezulu. Ngakolunye uhlangothi, uma uyazi ukuthi uzofuna ukwenza ngezikhathi ezithile, ukuprintwa okuncane, ungakhetha ikhamera yedijithali enikeza inani elilinganiselwe lokuxazulula, okungenzeka ulondoloze imali ethile.
Ishadi Lokubheka Isinqumo sekhamera
Leli tafula lizokunika umqondo wesilinganiso sokuxazulula udinga ukwenza kokubili amaphuzu wezinga eliphezulu nezindinganiso eziphezulu. Ukudubula esinqumweni esibekwe lapha akuqinisekisi ukuthi ungenza ukuphrinta kwekhwalithi ephezulu ngobukhulu obhalwe ohlwini, kodwa izinombolo zizokunikeza okungenani indawo yokuqala yokunquma ubukhulu bokuphrinta.
| Isixazululo sidinga ukulinganisa okuhlukahlukene | ||
| Isixazululo | Avg. ikhwalithi | Ikhwalithi engcono |
| Ama-megapixels angu-0.5 | 2x3 ku. | NA |
| Ama-megapixel angu-3 | I-5x7 in. | I-4x6 in. |

Ungaphinda ulandele ifomula jikelele ukukusiza ukuthola isinqumo esiphezulu lapho ufuna ukudubula khona ubukhulu obuqondile bokuphrinta ofuna ukukwenza. Ifomula iqala ukuthi uzokwenza ukuphrinta emaqenjini angu-300 x 300 nge intshi (dpi), okuyinto isinqumo sokuphrinta esivamile sezithombe eziphezulu. Yandisa ububanzi nokuphakama (ngamasentimitha) ngobukhulu besithombe ofuna ukuzenza ngamakhulu angu-300. Bese uhlukanisa ngezigidi ezingu-1 ukucacisa inani lama-megapixels ukurekhoda.
Ngakho uma ufuna ukwenza ukuphrinta okungama-intshi engu-10 no-13, ifomula yokunquma inombolo encane yama-megapixel izobukeka kanje:
(Amasentimitha angu-300 * 300) * (amasentimitha angu-13 * 300) / 1 million = 11.7 megapixels
