Kusintha kwa chithunzi ndi chiwerengero cha madontho kapena pixel pa mainchesi onse amalo. Izi zimasankha momwe chithunzicho chikuwonekera Mwachilengedwe, chithunzi chomwe chili ndi pixel 72 mu inchesi imodzi chikhale chamtundu woyipa kuposa chithunzi chokhala ndi malingaliro a 300 dpi.
Ndizofunikira kudziwa kuti polojekiti simukuwona kusiyana pakati pa zosankha, tikungolankhula za kusindikiza.
Popewa kusamvana, timatanthauzira mawuwo dontho ndi pixel, chifukwa, m'malo mwa tanthauzo lenileni "ppi" (ma pixel inchi), mu Photoshop imagwiritsa ntchito "dpi" (dpi). Pixel - mfundo polojekiti, ndipo dontho - izi ndi zomwe zimayika chosindikizira pamapepala. Tidzagwiritsa ntchito zonse ziwiri, chifukwa pankhaniyi zilibe kanthu.
Zithunzi
Kukula kwenikweni kwa chithunzichi, ndiye kuti, zomwe timapeza tikatha kusindikiza, zimatengera mtengo wotsimikiza. Mwachitsanzo, tili ndi chithunzi chomwe chili ndi ma pixel a 600x600 ndi malingaliro a 100 dpi. Kukula kwenikweni kudzakhala mainchesi 6x6.
Popeza tikulankhula za kusindikiza, tikuyenera kuwonjezera chisankho ku 300dpi. Pambuyo pa izi, kukula kosindikizira kudzachepa, chifukwa inchi tikuyesera "kukwana" zambiri. Tili ndi ma pixel ochepa ndipo ali mgawo laling'ono. Malinga ndi izi, kukula kwake kwenikweni kwa chithunzicho ndi mainchesi awiri.
Sinthani chisankho
Tikuyang'anizana ndi ntchito yowonjezera malingaliro ojambula kuti akonzekere kusindikiza. Quality pankhaniyi ndichofunika kwambiri.
- Kwezani chithunzi ku Photoshop ndikupita kumenyu "Chithunzi - Kukula Zithunzi".
- Pazenera la makulidwe, tili ndi chidwi ndi magawo awiri: "Makulidwe" ndi "Kukula". Malo oyamba amatiuza kuchuluka kwa pixel pachithunzichi, ndipo chachiwiri - malingaliro apano ndi kukula kwake komwe.
Monga mukuwonera, kukula kwa kusindikiza ndi 51.15 x 51.15 cm, omwe ndi ochulukirapo, ichi ndi chithunzi chooneka bwino.
- Tiyeni tiyesetse kuwonjezera lingaliro lake kukhala ma pixel 300 pa inchesi ndikuwona zotsatira.
Zizindikiro zamagetsi zakula koposa katatu. Izi ndichifukwa choti pulogalamuyo imangodzipulumutsa yokha kukula kwachithunzithunzi. Pazifukwa izi, Photoshop wathu wokondedwa ndikuwonjezera ma pixel omwe alembedwa, ndikuwatulutsa pamutu. Izi zimaphatikizapo kutaya kwa mtundu, monga kukula kwachithunzi.
Popeza kuponderezana kunkagwiritsidwa ntchito pachithunzichi Jpeg, zopanga zojambula zamtunduwo zidawonekera pa iyo, zowonekera kwambiri pakhungu. Izi sizitikwanira konse.
- Njira yophweka itithandizira kupewa kugwa. Ndikokwanira kukumbukira kukula koyambirira kwa chithunzichi.
Onjezani chisankho, kenako lembani zofunikira zoyambirira.
Monga mukuwonera, kukula kwa kusindikiza kwasinthanso, tsopano tikasindikiza, timapeza chithunzi kupitirira 12x12 cm bwino.
Kusankha Kusintha
Mfundo pakusankha mayankho ndi motere: kuyang'ana kwambiri wopenyerera chithunzicho, kufunikira kwake ndikofunikira.
Pazosindikizidwa (makhadi a bizinesi, timabuku, ndi zina), mulimonse, chilolezo cha osachepera 300 dpi
Kwa zikwangwani ndi zikwangwani zomwe owonera angayang'ane nazo kuchokera patali pafupifupi 1 - 1.5 m kapena kupitilira, zambiri sizofunikira, chifukwa mutha kutsitsa mtengo kuti 200 - 250 pixel inchesi
Sakani mawindo, pomwe wowonera akutali, atakongoletsedwa ndi zithunzi zogwirizana ndi 150 dpi
Zikwangwani zazikulu zotsatsa, zomwe zimakhala kutali kwambiri ndi wowonera, kupatula kuwawona mwachidule, zidzawononga ndalama zambiri 90 madontho inchi iliyonse.
Zithunzi zolemba zolemba kapena kungolemba pa intaneti, zokwanira 72 dpi
Mfundo ina yofunika posankha mawonekedwe ndi kulemera kwa fayilo. Nthawi zambiri, opanga amapanga molakwika zithunzi za ma pixel inchi, zomwe zimapangitsa kuti chiwonetserocho chiwonjezeke. Tengani, mwachitsanzo, chikwangwani chomwe chili ndi miyeso yotalika 5x7 mamita ndi malingaliro a 300 dpi. Ndi magawo awa, chikalatacho chidzakhala pixel pafupifupi 60000x80000 ndipo "chikoka" pafupifupi 13 GB.
Ngakhale kuthekera kwa chipangizo cha kompyuta yanu kumakulolani kuti mugwire ntchito ndi fayilo ya kukula uku, nyumba yosindikiza ndiyokayikitsa kuvomera kuti ichitikire kuntchito. Mulimonsemo, zidzakhala zofunikira kufunsa zofunikira.
Izi ndi zonse zomwe zitha kunenedwa za kapangidwe ka zithunzi, momwe mungasinthire, komanso mavuto omwe mungakumane nawo. Yang'anani mwatchutchutchu momwe kusinthika ndi mtundu wa zithunzi zomwe zikuwonekera zikuwonekera komanso kusindikiza zikukwaniritsidwa, komanso kuchuluka kwa madontho mulimonse okwanira inchi zosiyanasiyana.
