Ngati mukufuna kukulitsa chinthu mu Photoshop, mungagwiritse ntchito njira ya Interpolation. Njira iyi ikhoza kuonjezera ndi kuchepetsa chithunzi choyambirira. Pali mitundu yambiri ya njira ya Interpolation; njira yosiyana imalola kuti mupeze chithunzi cha khalidwe linalake.
Mwachitsanzo, ntchito yowonjezera kukula kwa chifaniziro choyambirira imaphatikizapo kulengedwa kwa pixel yowonjezera, mtundu wa mtundu umene umayenderana kwambiri ndi ma pixelera oyandikira.
Mwa kuyankhula kwina, ngati mapilosi a black and white ali pambali pa chithunzi choyambirira, pamene chithunzicho chikufutukuka, ma pixel atsopano a imvi adzawoneka pakati pa pixels awiriwa. Pulogalamuyo imapanga mtundu womwe ukufunidwa mwa kuwerengera mtengo wa ma pixel pafupi.
Njira Zowonongeka
Mfundo yapadera "Kupanikizika" (Resample Image) ali ndi matanthauzo angapo. Zimayambira pamene mumayendetsa mndondomeko pamtsinje womwe ukulozera ku parameter. Taganizirani ndime iliyonse.
1. "Potsatira" (Wokondedwa wapamtima)
Pogwiritsa ntchito fanoyi imagwiritsidwa ntchito mosalekeza, chifukwa khalidwe lawonjezedwayo ndi loipa. Pa zithunzi zofutukuka, mungapeze malo pomwe pulogalamuyi inaphatikizapo mapikseli atsopano, izi zimakhudzidwa ndi kufunika kwa njira yopanga. Pulogalamuyi imapanga mapikseli atsopano poyandikira pojambula pafupi.
2. "Bilinear" (Bilinear)
Pambuyo pochita zozizwitsa ndi njira iyi, mudzapeza zithunzi za khalidwe labwino. Photoshop idzapanga mapikseli atsopano powerenga mtundu wa ma pixel oyandikana nawo, kotero kuti kusintha kwa mtundu sikudzawonekera.
3. "Bicubic" (Bicubic)
Ndibwino kuti tigwiritse ntchito kuti muwonjezere pang'ono mu Photoshop.
Mu Photoshop CS ndi apamwamba, mmalo mwa njira yeniyeni ya bicubic, zowonjezereka zowonjezera ziwiri zingapezeke: "Bicubic ironing" (Bicubic ikuyenda bwino) ndi "Bicubic bwino" (Bicubic sharper). Kugwiritsa ntchito, mungapeze zithunzi zowonjezereka kapena zochepetsedwa ndi zotsatira zina.
Mu njira ya bicubic yopanga pixelisi zatsopano, kuwerengetsa kovuta kwamtundu wa ma pixel ambiri pafupi kumapangidwira, kupeza khalidwe labwino la chithunzi.
4. "Bicubic Ironing" (Bicubic ikuyenda bwino)
Kawirikawiri amagwiritsidwa ntchito kubweretsa chithunzi ku Photoshop pafupi, koma malo omwe ma pixel atsopano anawonjezeredwa sakuwoneka.
5. "Bicubic bwino" (Bicubic sharper)
Njira iyi ndi yangwiro yopitilira, ndikupanga chithunzichi momveka bwino.
Chitsanzo chogwiritsa ntchito mtengo "Bicubic ironing"
Tiyerekeze kuti tili ndi chithunzi chomwe chiyenera kuwonjezeka. Kukula kwazithunzi -
531 x 800 px ndi chilolezo 300 dpi.
Kuti mupange zojambulazo muyenera kupeza mndandanda Chithunzi - Chithunzi Chamafanizo (Chithunzi - Zithunzi Zamtengo).
Pano muyenera kusankha chinthu chomwecho. "Bicubic ironing"ndikutembenuzira miyeso ya fano mpaka magawo.
Poyambirira, chikalata choyambirira chikukhudza 100%. Kuwonjezeka kwa chikalatacho chidzachitika pang'onopang'ono.
Choyamba, yonjezerani kukula kwake 10%. Kuti muchite izi, sintha chizindikiro cha fano 100 pa 110%. Ndi bwino kulingalira kuti pamene mutasintha m'lifupi, pulogalamuyo imasintha kutalika kwake. Kuti muzisunga kukula kwatsopano, pezani batani. "Chabwino".
Tsopano kukula kwa fano ndi 584 x 880 px.
Mwanjira imeneyi mukhoza kuyang'ana momwe mukufunira. Kuwonekera kwa chithunzi chokweza kumadalira pazinthu zambiri. Zazikulu ndi khalidwe, chisankho, kukula kwa chithunzi choyambirira.
Ndi kovuta kuyankha funso la momwe mungayang'anire kuti mupeze chithunzi chabwino. Izi zikhoza kupezeka poyambira kuwonjezeka pogwiritsira ntchito pulogalamuyi.
