Kutheni iifoto zifuna ukuxhalabisa ngeCompresssion yeSithombe
Ukuxinezeleka kuyimbambano enkulu xa kuziwa kwiifoto kwaye kulula kakhulu ukutshabalalisa umfanekiso omkhulu ngokuxineka kakhulu kwaye kaninzi. Kubalulekile ukuqonda ukunyanzela kwi-digital photography, ukuze ukwazi ukuyilawula ngokufanelekileyo ukuhlangabezana neemfuno zesithombe esithile.
Yintoni iCompression?
Ukunyanzeliswa kusetyenziswa ukunciphisa ubungakanani befayili kwikhomputha, kuquka iifayile zefayile. Iifayile zixinyiwe ukunciphisa ubukhulu bazo kwaye zenze kube lula ukwabelana kwiwebhu. Nangona kunjalo, xa kuziwa kwiifoto, ukunyanzelisa akusoloko kulungile.
Iifom zeefayile zeefayile ezihlukileyo kwiikhamera ze- DSLR kunye neekhomputha zisebenza amanqanaba ahlukeneyo okuxinwa. Xa umfanekiso ucindezelwe (kwikhamera okanye kwikhompyutha) kukho ulwazi oluncinci kwifayili kunye neenkcukacha ezigqithiseleyo zombala, ulwahlulo kunye nobukhali buyancitshiswa.
Ngefomati yoxinzelelo olufana nelo kufumaneka kwifayile yeJPEG, uya kukwazi ukulungelelanisa ezininzi iifayile kwiimemori khadi yekhamera, kodwa unomgangatho wokubonga. Abafaki beefoto eziphambili bazama ukuphepha ukunyanzeliswa ngokudubula iifayile ze-RAW, ezingenakho ukunyanzeliswa ezisetyenziswa kubo. Nangona kunjalo, ngokufotela ngokubanzi, ukunyanzeliswa okufumaneka kwi-JPEG akusiyo impendulo ebalulekileyo.
Ukwazisa Inkcazo
Ukwahluka kwimiqulu yoxinzelelo kungabonakali kwikrini yekhamera ye- LCD okanye kwikhompyutha. Kuya kubonakala kakhulu xa ushicilela umfanekiso kwaye uza kudlala indima enkulu xa unenjongo yokuba loo mfanekiso ikhuliswe. Nokuba umgangatho wokuprinta u-8x10 unokuba nefuthe kakhulu. Kodwa ukuba nje ukwabelana ngesithombe kumajelo asekuhlaleni, ukulahlekelwa kwekhwalithi ngokunyanzeliswa akufanele kukuchaphazele ngokwaneleyo ukuba kubonakale.
I-digital photography iye yaqhubela phambili kwiminyaka yamuva. Abaninzi beefoto bafuna ikhamera yakutsha kunye nama-megapixels amaninzi kwaye baya kuqhubeka bephucula. Nangona kunjalo, ukuba lowo mfanekiso weefoto-mpahla akayithobeli ingqalelo kwi-compress ukususela ngexesha umfanekiso uthathwa ngokulandelwa kwemveliso emva kokuveliswa nokugcinwa, ngoko bachitha nje umgangatho owongezelelweyo abawuhlawulele.
Indlela yeCompression Compress Actual Works
Ukunyanzela idijithali yinkqubo ephindwe kabini.
Okokuqala, inzwa yedijithali inakho ukuthatha ulwazi olude ngakumbi kunokuba iliso lomntu lingakwazi ukwenza. Ngoko ke, ezinye zeenkcukacha ziyakususwa ngexesha loxinzelelo ngaphandle kokuba umbukeli azibonele!
Okwesibini, indlela yokunyanzeliswa iya kubheka nayiphi na indawo eninzi yokuphindaphinda umbala, kwaye iza kususa ezinye zeendawo eziphindaphindiweyo. Baya kuhlaziywa kwakhona kumfanekiso xa ifayile ifakwa.
Iintlobo ezimbini zeCompression Compression
Ku luncedo ukuqonda iintlobo ezimbini ezahlukeneyo zoxinzelelo ukuze siyiqonde imiphumo yabo kwiifayile.
Ukunyanzeliswa okungenasiphelo
Oku kufana nokudala ifayile ye - ZIP kwikhompyutha. Idatha icinezelwe ukuba yenze incinci, kodwa akukho mgangatho olahlekileyo xa ifayili icatshulwa kwaye ivuliwe ngobukhulu obupheleleyo. Kuya kufana nomfanekiso wokuqala.
I-TIFF yifom yefayile esetyenziswe ngokuqhelekileyo esebenzisa ukunyanzeliswa kokulahlekelwa.
Ukunyanzeliswa kokulahlekelwa
Olu hlobo lwenkcenkceshe lusetyenziswa ngokulahla ulwazi kunye nemali yokusetyenziswa kancinci kunokukhethwa ngu-photographer.
I-JPEG iyifom yefayile eqhelekileyo isetyenzisiweyo, kwaye ivumela abathwebuli beefoto ukuba bagcine indawo kwimakhadi ememori okanye bavelise iifayile ezifanelekileyo zokuthumela i-imeyile okanye ukuthumela i-intanethi. Nangona kunjalo, kufuneka kuqatshelwe ukuba xa uvula, uguqula, kwaye ugcine kwakhona ifayile "yelahleko", ingcaciso encinane ilahlekile.
Iingcebiso zokuKhusela iiNgxaki eziPheleleyo
Kukho amanyathelo apho naluphi na umfaki-zithombe onokuyithatha ukuphepha ukulahlekelwa umgangatho weefoto zabo ukuxinzezela.
- Shoot ku-RAW ukuba ikhamera yakho ikuvumela. Ukuba ubungakanani befayile kunye nomthamo wokugcina umcimbi kuwe, fumana amakhadi abambe ulwazi oluninzi. I-RAM ngoku ixabiso elincinci kwaye libiza kakhulu ukuthenga amakhadi amemori ayi-16 okanye 32 GB. Oku akusisisisizathu!
- Gcina iifayile zakho zokusebenza kunye nokugqiba iifayile njengeTIF. Emva kokuguqulwa kwi-RAW kwaye uye wakhulisa imifanekiso yakho, gcina loo mifanekiso yokugqibela kwifomati yefayili engalahlekanga kunye nevenkile ekhuselekileyo. Sebenzisa kuphela i-JPG yokwabelana, kodwa yonke ixesha kufuneka usebenze kule fayili ukuze uhlaziywe, buyele kwifayile engenakulahlekelwa.
- Yeka ukulondoloza kwiifayile zeJPG! Njengoko kukhankanywe ngasentla, rhoqo xa uvula kwaye uphinde ulondoloze ifayile yexinzelelo yokulahlekelwa njengeJPGs, ulahlekelwa ngumgangatho wesithombe kwaye ngaphambi kokuba wazi, uya kushiywa ngomfanekiso we-mush.
