Chifukwa Chimene Ojambula Akuyenera Kudzisamalira ndi Image Compresssion
Kulimbana ndi vuto lalikulu pankhani ya zithunzi ndipo ndi zophweka kwambiri kuwononga chifaniziro chachikulu pochikakamiza kwambiri komanso nthawi zambiri. Ndikofunika kumvetsetsa zojambulajambula mu kujambula kwajambulajambula, kuti muthe kuzigwiritsa ntchito bwino kuti mukwaniritse zosowa za zithunzi.
Compression ndi chiyani?
Kugwiritsiridwa ntchito kumachepetsa kukula kwa fayilo iliyonse pamakompyuta, kuphatikizapo mafayilo a zithunzi. Maofesi amaumirizidwa kuti achepetse kukula kwake ndikuwapangitsa kukhala kosavuta kugawa pa intaneti. Komabe, pankhani ya zithunzi, kuponderezana sikuli chinthu chabwino nthawi zonse.
Maofesi osiyanasiyana ojambula zithunzi pa makamera a DSLR ndi makompyuta amagwiritsa ntchito zovuta zosiyanasiyana. Pamene fano liri lopanikizidwa (mu kamera kapena kompyuta) pali zambiri zochepa mu fayilo ndipo maonekedwe abwino kwambiri a mtundu, kusiyana, ndi kuwongolera amachepetsedwa.
Ndi machitidwe ophatikizana monga omwe amapezeka mu fayilo ya JPEG, mudzatha kulumikiza mafayilo pa khadi lakumamera la kamera, koma mumaperekanso khalidwe la nsembe. Ojambula apamwamba amayesetsa kupeŵa kuponderezana powombera mafayilo a RAW, omwe alibe kuponderezedwa kwa iwo. Komabe, pofuna kujambula zithunzi zambiri, kupanikizika komwe kumapezeka mu JPEG sikumbuyo kwenikweni.
Kusinkhasinkha Kumvetsetsa
Kusiyanitsa kwa machitidwe opanikizika sikungakhoze kuoneka pawindo la LCD la kamera kapena ngakhale pulogalamu ya makompyuta. Zidzakhala zoonekeratu pamene mukujambula chithunzi ndipo mutha kugwira nawo ntchito yaikulu ngati mukufuna kuti chithunzicho chikulitsidwe. Ngakhale khalidwe la 8x10 kusindikiza likhoza kuthandizidwa ndi kupanikizika kwambiri. Koma ngati mukugawana chithunzi pazolumikizidwe, kutayika kwa khalidwe mwa kupanikizika sikuyenera kukukhudzani mokwanira kuti muoneke.
Kujambula zithunzi zapadela kwapita patsogolo kwambiri m'zaka zaposachedwa. Ambiri ojambula amafuna kamera yamakono kuti ikhale ndi maimapixel kwambiri ndipo idzasintha. Komabe, ngati wojambula zithunziyo samamvetsera kupanikizika kuchokera nthawi yomwe fano limagwidwa kupyolera mwa kupanga ndi kusungirako, ndiye kuti amangotaya khalidwe lomwe adalipiritsa.
Momwe Zimagwirira Ntchito Zomwe Zimagwirira Ntchito
Kuponderezedwa kwa Digital ndi njira ziwiri.
Choyamba, makina a digito amatha kulandira chidziwitso chochuluka kuposa diso la munthu lomwe lingathe kukonza. Choncho, zina mwazomwezi zikhoza kuchotsedwa panthawi yopanikizika popanda wowonayo akuzindikira!
Chachiwiri, kupanikizika kudzayang'ana mbali iliyonse yayikulu yobwerezabwereza, ndipo idzachotsa mbali zina zobwerezabwereza. Iwo adzakonzanso kukhala fano pamene fayilo ikufutukulidwa.
Mitundu Iwiri ya Kuphatikizidwa Kwa Mafano
Ndikofunika kumvetsetsa mitundu iwiri ya kupanikizana kuti titha kumvetsa zotsatira zomwe ali nazo pa mafayilo.
Kupanikizika kopanda Phindu
Izi zikufanana ndi kupanga fayilo ya ZIP pa kompyuta. Deta ilimbikitsidwa kuti ikhale yaing'ono, koma palibe khalidwe lomwe latayika pamene fayilo imachotsedwa ndi kutsegulidwa pa kukula kwathunthu. Zidzakhala chimodzimodzi ndi chithunzi choyambirira.
TIFF ndiyo mafayilo omwe amagwiritsidwa ntchito kwambiri omwe amagwiritsa ntchito kuperewera kosawonongeka.
Kusokonezeka kwa Kutaya
Kupanikizika kotereku kumagwira ntchito pochotsa chidziwitso ndi kuchuluka kwa kuponderezedwa kugwiritsidwa ntchito kungasankhidwe ndi wojambula zithunzi.
JPEG ndi njira yomwe amagwiritsidwa ntchito kawirikawiri pamasom'pamaso, ndipo amalola ojambula kusunga malo pamakhadi amakalata kapena kupanga mafayilo oyenera kutumizira ma-e-mail kapena kutumiza pa intaneti. Komabe, dziwani kuti nthawi iliyonse mukatsegula, kusintha, ndikusunganso fayilo "yotayika", tsatanetsatane wambiri imatayika.
Malangizo Othandizira Mavuto Ovuta
Pali zochitika zomwe aliyense wojambula zithunzi angatenge kuti asatayike khalidwe la zithunzi zawo kuti asokonezeke.
- Fuulani mu RAW ngati kamera yanu ikulolani kutero. Ngati kukula kwa fayilo ndi mphamvu yosungirako ndizovuta kwa inu, pezani makadi omwe amadziwa zambiri. RAM tsopano ndi yotsika mtengo ndipo ndi yotsika mtengo kwambiri kugula makadi a kukumbukira 16 kapena 32 GB. Izi sizowonjezera!
- Sungani mafayilo anu ogwira ntchito komanso omaliza monga TIF. Mutasinthidwa kuchokera ku RAW ndipo mwakulitsa mafano anu, sungani mafano omalizira mu fayilo yopanda pake ndi ma sitolo omwe ali otetezeka. Gwiritsani ntchito JPG zokhazokha, koma nthawi iliyonse yomwe mukufuna kugwira ntchito pa fayiloyi kuti musinthe, bwererani ku fayilo yopanda pake.
- Lekani kusunga mafayilo a JPG! Monga tafotokozera pamwambapa, nthawi iliyonse yomwe mutsegula ndikusunganso fayilo yosavuta yojambulidwa ngati JPGs, mumataya khalidwe lazithunzi ndipo musanadziwe, mudzasiyidwa ndi chithunzi cha bowa.
