Fumana izicwangciso ezilungelelaniso kwiNgxaki nganye
Xa kuziwa ukulungelelanisa izicwangciso zekhamera yakho ukufezekisa imifanekiso engcono kakhulu, enye into abaninzi abayikhumbule ngayo iifoto ezikhunjweyo malunga nokubeka umgangatho wesithombe kunye nobukhulu bomfanekiso kumazinga afanelekileyo. Uninzi lwexesha, ukudubula kwisisombululo esisisigxina yiyona nto ingcono. Kodwa ngamanye amaxesha, isayizi encinane yekhamera yefayile yesikrini yindlela efanelekileyo yokubakhomba.
Ukuqulunqa izicwangciso ezifanelekileyo akusoloko kulula. Umzekelo, ukuba imemori khadi yakho iqalisa ukugcwalisa, unokufuna ukudubula ubuncinane bezithombe okanye umgangatho ukugcina indawo eninzi yokugcina. Okanye, ukuba uyazi ukuba uya kusebenzisa isethi ethile yezithombe kwi-imeyile okanye kwi-intanethi yentlalo, unokudubula kwisisombululo esezantsi kunye nomgangatho ophantsi wezithombe, ngoko iifoto azithathi ixesha elide ulayishe.
Sebenzisa ezi ngcebiso ukukunceda ufumane izilungiso ezifanelekileyo kwiimfuno zakho zokufotela kwiimeko ezithile zokudubula.
I-megapixel nganye ayiyi & # 39; idalwe ilinganayo
Enye indawo edidekayo kubafoto bezithombe abafudukela kwinqanaba kwaye bathabathe ikhamera kwi-DSLR izama ukusebenzisa kuphela i- megapixels ukulinganisa umgangatho womfanekiso. Iikhamera ze-DSLR kunye neekhamera ezijoliswe phambili eziqhelekileyo zisebenzisa i-image sensor enkulu kunokwicala kunye nokudubula iikhamera, ezivumela ukuba benze umgangatho ophezulu mfanekiso xa besebenzisa inombolo efanayo yeegapixel. Ngoko ukubeka ikhamera ye-DSLR ukudubula umfanekiso we-megapixel we-10 kufuneka udale umphumo ongcono ngakumbi kunokuba ubeke iphuzu uze uphese ikhamera ukudubula umfanekiso we-megapixel we-10.
Sebenzisa inkinobho yeNkcukacha ngenzuzo
Ukubona izicwangciso zekhwalithi zangoku kunye nekhamera yakho, cinezela inkinobho Yenkcukacha kwikhamera yakho, kwaye kufuneka ubone izicwangciso zangoku kwi-LCD. Ngenxa yokuba iifayile zeenkcukacha zixhomekeke kwiikhamera ze-DSLR, ukuba ikhamera yakho ayinayo inkinobho yeenkcukacha, unokufuna ukuba usebenze ngamamenyu ekhamera kunokuba ufumane izicwangciso zekhwalithi. Ngokuqhelekileyo kunye neekhamera ezintsha, ke, uya kufumana inani lee-megapixels apho udlalwa ngoku ziza kuboniswa kwikona yesikrini seLCD.
Cinga iifayile ze-RAW eziphezulu zefayile
Uninzi lweekhamera ze-DSLR zingadla kwiifayile ze- RAW okanye ze-JPEG . Kulabo abathanda ukwenza uhlaziyo lwezithombe zabo ngokwabo, ifomathi yefayile ye-RAW ikhethwa ngenxa yokuba akukho kuqukumbeka kwenzeka. Nangona kunjalo, kubalulekile ukuba ukhumbule ukuba iifayile ze-RAW ziza kuhlala kwindawo engakumbi yokugcina kuneefayile zeJPEG. Kwakhona, ezinye iintlobo zesofthiwe ayikwazi ukubonisa iifayile ze-RAW ngokulula njengeifayile ze-JPEG.
Okanye sebenzisa ii-RAW kunye ne-JPEG kunye
Uninzi lweekhamera ze-DSLR, ungagcina iifoto kwiifayile zefayile ze-JPEG kunye ne-RAW ngexesha elifanayo, ezinokuthi zenzeke ngokuqinisekileyo ukuba unokugqiba nomfanekiso ongcono. Kwakhona, nangona kunjalo, oku kuza kukudinga indawo eninzi yokugcinwa kwesithombe esinye kunokuba udubule kwi-JPEG kuphela, ke qiniseka ukuba unendawo eninzi yokugcina. Ukuqala iifoto-zithombe, ukudubula kwi-RAW akunakulungelekanga, njengokuba abafotozi kuphela abaceba ukusebenzisa isofthiwe yokuhlela umfanekiso kwiifoto zabo kufuneka baxineke nge-RAW yokudubula.
I-JPEG yokunciphisa ukulingana
Ngeentlobo zefayile zeJPEG, ngamanye amaxesha unokhetho phakathi kweendlela ezimbini okanye ezintathu ze-JPEG. I-JPEG Fine ibonisa umlinganiselo wokunciphisa u-4: 1; I-JPEG eqhelekileyo isebenzisa u-8: 1 isilinganiso soxinzelelo ; kwaye i-JPEG Isisiseko isebenzisa ukulinganisa kwe-16: 1. Umlinganiselo wokunciphisa ophantsi uthetha ubungakanani befayili enkulu kunye nomgangatho ongcono.
Qonda ukuhluka phakathi kobukhulu kunye nobukhulu
Gcina ukhumbule ukuba ubukhulu bezithombe buhluke kumgangatho wesithomo kwisetyu zekhamera . Ubungakanani bezithombe bubhekisela kwinani langempela leepekseli ikhamera iyisindisa ngesithombeni ngasinye, ngelixa umgangatho wesithombe ubhekisela kwindlela echanekileyo okanye ukuba yeyiphi inkulu loo pixel. Umgangatho wesithombe unokuthi ube "oqhelekileyo," "ococekileyo" okanye "ophezulu," kwaye ezi zicwangciso zibhekisela ekuchanekeni kwamaphikseli. Iipekiseli ezichanekileyo ziza kubangela umfanekiso ogqithisileyo, kodwa ziza kufuna enye indawo yokugcina kwimemori khadi, okubangele ubukhulu befayile.
Ukuthabatha enkulu, ephakathi, okanye encinci
Ezinye iikhamera zezinga lokuqala azibonisi inani elichanekileyo lamagapixel kwisisombululo sesithombeni ngasinye, endaweni yoko ubiza iifoto "ezinkulu," "eziphakathi," kunye "ezincinci," ezinokuba ziphazamisekile. Ukukhetha enkulu njengokuba ubungakanani bomfanekiso bunokubangela isithunzi kunye nama-megapixel angama-12-14, ngelixa ukhetha encinci njengokuba ubungakanani bomfanekiso bungabangela ama-megapixels ama-3-5. Ezinye iikhamera zezinga lokuqala ziluhlu kuphela uluhlu lwee-megapixel njengenxalenye yemenyu yesayizi yemifanekiso.
Ungakwazi ukulawula ubukhulu beefayile zevidiyo
Kuyafaneleka kwakhona ukukhumbula ukuba xa udlala ividiyo, ezininzi zezi khokelo ezifanayo ziyasebenza ngokwemigangatho yevidiyo kunye nomgangatho wevidiyo. Unokuzilungelelanisa ezi zicwangciso kumamenyu ekhamera, ukuvumela ukuba udubule kwividiyo esemgangathweni ukuhlangabezana neemfuno zakho.
