Pangani Zithunzi Zanu Zambiri Ndi Kutaya Kwambiri Kwambiri
Funso lofunsidwa kawirikawiri pokhudzana ndi mapulogalamu a mafilimu ndi momwe mungakwirire kukula kwa chithunzi popanda kuyankhulana ndi kumbuyo. Ogwiritsa ntchito nthawi zambiri amadabwa akamakhala ngati fano ndikupeza kuti khalidweli ndi loipa kwambiri. Ogwiritsa ntchito odziwa zambiri akudziŵa bwino vutoli. Chifukwa cha kuwonongeka ndi chifukwa chakuti fano , kapena raster, mitundu ya fano imalephera ndi chiganizo chawo cha pixel. Mukayesera kusintha zithunzizi, pulogalamu yanu imayenera kuwonjezera kukula kwa pixel ya munthu aliyense - zomwe zimapangitsa fano losasunthika - kapena "kulingalira" mwanjira yabwino yowonjezera ma pixels ku chithunzi kuti chikhale chachikulu .
Posakhalitsa, panalibe njira zambiri zowonjezera chisankho kupatula kugwiritsa ntchito njira zowonetsera pulogalamuyi. Lero, ife tikukumana ndi zowonjezereka kuposa kale. Inde, nthawi zonse ndibwino kuti mulandire chisankho chomwe mukuchifuna kuyambira pachiyambi. Ngati muli ndi mwayi wosankhira fano pachigwirizano chachikulu, mwa njira zonse, muyenera kuchita zimenezi musanayambe kugwiritsa ntchito mapulogalamu. Ndipo ngati muli ndi ndalama kuti muyike mu kamera yomwe ili ndi zifukwa zomveka, mungagwiritse ntchito kuti ndalama zimagwiritsidwa ntchito bwino kuposa ngati mutayikamo muzothetsera mapulogalamu. Atanena zimenezi, nthawi zambiri nthawi zina simungakhale ndi chisankho china kusiyana ndi kugwiritsa ntchito mapulogalamu. Pamene nthawiyo ifika, ndizo mfundo zomwe muyenera kudziwa.
Kuperekera mphoto vs. Kutsutsana
Mapulogalamu ambiri ali ndi lamulo limodzi lokhazikitsa ndi kuyimitsa. Kupewera chithunzi kumaphatikiza kusintha kusintha kwazithunzi popanda kusintha miyeso ya pixel yonse. Pamene chigamulo chikuwonjezeka, kukula kwa kusindikiza kumakhala kochepa, komanso mosiyana. Mukamapanga chisankho musasinthe miyeso ya pixel, palibe kutayika mu khalidwe, koma muyenera kupereka kukula kwa kusindikiza. Kusintha fano pogwiritsira ntchito zowonongeka, komabe kumaphatikizapo kusintha miyeso ya pixel ndipo nthawi zonse kumatayika kuwonongeka. Ndichifukwa chakuti kuyambanso kumagwiritsa ntchito njira yotchedwa interpolation yoonjezera kukula kwa fano. Ndondomekoyi ikulingalira zoyenera za mapilosi omwe mapulogalamuwa amafunika kulenga kuchokera pa mapikisilosi omwe alipo mu fano. Kupemphanso kudzera pamagulu a zilankhulo kumakhala kovuta kwambiri pakati pa fano losinthidwa, makamaka m'madera omwe muli mizere yakuthwa ndi kusintha kwa mtundu.
• Pakati pa Kukula kwa Zithunzi ndi Kusintha
Mbali ina ya nkhaniyi ndi kukwera kwa ma smartphone ndi piritsi ndi zomwe zikugwirizana ndi pixel ya chipangizo. . Zida zimenezi zili ndi pixeliti ziwiri kapena zitatu pamalo omwewo omwe amakhala ndi pixel imodzi pakompyuta yanu. Kusuntha chithunzi kuchokera pa kompyuta yanu kupita ku chipangizo kumafuna kuti muzipanga zithunzi zofanana (mwachitsanzo 1X, 2X ndi 3X) kuti muwonetsetse kuti akuwonetsa bwino pa chipangizocho. Kodi wina amakula kukula kwa fano kapena kuwonjezera chiwerengero cha pixelisi.
Njira Zowonjezereka Zotsutsana
Mapulogalamu okonzekera zithunzi amapereka njira zingapo zowerengera zowerengera ma pixel atsopano pamene chithunzi chathu chatchulidwa. Nazi malingaliro a njira zitatu zomwe zilipo mu Photoshop. Ngati simugwiritsa ntchito Photoshop, pulogalamu yanu mwina imapereka zosankha zofanana ngakhale kuti angagwiritse ntchito mawu osiyana pang'ono.
- Bicubic ndi yochedwa kwambiri koma imapanga kulingalira kwakukulu kwa miyeso yatsopano ya pixel.
- Bilinear ndifulumira kuposa bicubic, koma ntchito yosauka. Bicubic ndi bilinear interpolation zimabweretsa chithunzi chosasangalatsa, makamaka pamene mukukweza.
- Wokondedwa wapamtima samagwiritsa ntchito interpolation. Zimangotenga phindu la pixel yoyandikana ndikuwonjezera pixelsi zatsopano popanda kuzigawa. Izi ndi pamene mumapeza jaggies kapena step-step step effect.
Dziwani kuti pali njira zitatu zokha zomwe zingagwirizanitsidwe ndikugwiritsa ntchito njira yomweyo pamapulogalamu osiyanasiyana zingabweretse zotsatira zosiyana. Zomwe ndimakumana nazo, ndapeza kuti Photoshop ili ndi bicubic interpolation yabwino kwambiri ya mapulogalamu ena omwe ndawayerekezera.

Njira Zina Zopangira Mapulaneti
Mapulogalamu ena owonjezera omwe amapanga mafano amapereka zowonjezereka zomwe zimati zimapanga ntchito yabwino kuposa njira ya Photoshop ya bicubic. Zina mwa izi ndi Lanzcos , B-spline , ndi Mitchell . Mapulogalamu angapo omwe amapereka njira zowonjezerekazi ndi Qimage Pro, IrfanView (osasintha fano lajambula), ndi Zithunzi Zoyeretsa. Ngati pulogalamu yanu imapereka limodzi mwazinthu zowonongekazi kapena zina zomwe sizinatchulidwe pano, muyenera kuyesa nazo kuti muone omwe akukupatsani zotsatira zabwino. Mwinanso mungapeze kuti njira zosiyana zojambula zimapangitsa zotsatira zabwino malingana ndi fano lomwe amagwiritsidwa ntchito.
Kusamvana Kwambiri
Anthu ena apeza kuti mutha kupeza zotsatira zabwino pamene mukukweza zowonjezereka mwa kukula kwa kukula kwa fano muzinthu zing'onozing'ono zing'onozing'ono kusiyana ndi gawo limodzi lopambana. Njira imeneyi imatchulidwa kuti masitepe. Njira imodzi yogwiritsira ntchito stair interpolation ndi yakuti idzagwira ntchito pazithunzi za 16-bit komanso sizidzasowa mapulogalamu ena osiyana ndi ojambula zithunzi, monga Photoshop. Lingaliro la stair interpolation ndi lophweka: mmalo mogwiritsa ntchito kukula kwa fano kuti mupite mwachindunji kuchokera 100% mpaka 400%, mungagwiritse ntchito lamulo la kukula kwa chithunzi ndikungowonjezera, kunena, 110%. Ndiye mutha kubwereza lamulo nthawi zambiri zomwe zimatengera kuti mufike kukula komwe mukufunikira. Mwachiwonekere, izi zingakhale zovuta ngati pulogalamu yanu ilibe mphamvu yokha. Ngati mumagwiritsa ntchito Photoshop 5.0 kapena apamwamba, mutha kugula masitepe a Fred Miranda pa $ 15 US kuchokera pazomwe zili pansipa. Mudzapeza zambiri zowonjezereka ndi kufanizira mafano. Popeza nkhaniyi inalembedwa koyambirira, njira zatsopano zowonongeka ndi matekinoloje a pulogalamu zamakono zakhazikitsidwa zomwe zimapangidwira masitepe osasintha.
