Kusintha kwazithunzi ndi chiwerengero cha madontho kapena pixels pa square inch square. Zokonzera izi zimatsimikizira momwe chithunzicho chidzawonekere pamene chikasindikizidwa. Mwachibadwa, chithunzicho, chomwe chili ndi pixelisi 72 mu inchi imodzi, chidzakhala choyipa kwambiri kuposa chithunzi chomwe chili ndi ndondomeko ya 300 dpi.
Ndiyenela kudziŵa kuti pakuyang'ana kusiyana pakati pa zisankho zomwe simudzaziwona, ndizopangila kusindikiza.
Pofuna kupewa kusamvetsetsana, timatanthauzira mawu "mfundo" ndi "pixel"chifukwa mmalo mwa tanthauzo labwino "ppi" (pixels per inch) imagwiritsidwa ntchito ku Photoshop "dpi" (madontho ndi inchi). "Pixel" - onetsetsani kuwona, ndi "mfundo" - izi ndi zomwe zimayika papepala. Tidzagwiritsa ntchito zonse ziwiri, popeza zilibe kanthu.
Kusintha kwa zithunzi
Kuchokera ku mtengo wa chigamulochi kumadalira mwachindunji kukula kwake kwa fano, ndiko kuti, zomwe timapeza titatha kusindikiza. Mwachitsanzo, tili ndi fano ndi miyeso ya pixel 600x600 ndi chisankho cha 100 dpi. Kukula kwenikweni kudzakhala masentimita 6x6.
Popeza tikukamba za kusindikizira, muyenera kuwonjezera chigamulo cha 300dpi. Zitatha izi, kukula kwa zosindikizidwa kudzachepetsedwa, popeza tikuyesera "kunyamula" zina zambiri mu inchi. Tili ndi ziwerengero zochepa za pixeliti ndipo zimagwirizana m'dera laling'ono. Choncho, tsopano kukula kwake kwa chithunzichi ndi masentimita awiri.
Sintha chisankho
Ife tikuyang'anizana ndi ntchito yowonjezera chisankho cha chithunzi kuti tikonzekere kusindikiza. Chikhalidwe pa nkhaniyi ndi chinthu chofunika kwambiri.
- Ikani chithunzi mu Photoshop ndikupita ku menyu Chithunzi - Chithunzi Chamafanizo.
- Muwindo lazenera zazithunzi ife timakondwera ndi zigawo ziwiri: "Dimension" ndi "Kukula kwapafupi". Mbali yoyamba imatiuza ma pixel angati omwe ali pachithunzichi, ndipo chachiwiri - chigamulo cha pakali pano ndi zofanana zenizeni.
Monga momwe mukuonera, kukula kwa zolembazo ndi 51.15 x51.15 masentimita, zomwe ndizo zambiri, ndizojambula bwino kwambiri.
- Tiyeni tiyesere kuwonjezera chigamulocho mpaka ma pixelisi 300 pa inchi ndikuwona zotsatira.
Miyeso yawonjezeka ndi zochuluka katatu. Izi zili choncho chifukwa pulogalamuyo imasungira kukula kwake kwa fano. Pachifukwa ichi, timakonda kwambiri Photoshop ndikuwonjezera chiwerengero cha ma pixel mu chikalata, ndipo timachokera "kumutu." Izi zimaphatikizapo kutayika kwa khalidwe, monga kukula kwa chithunzichi.
Popeza chithunzicho chinkagwiritsidwa ntchito kale Jpeg, zojambula zodziwika ndi mawonekedwe omwe amaonekera pa izo, zomwe zimawonekera kwambiri pamutu. Izo sizikugwirizana nafe nkomwe.
- Kulandira kophweka kudzatithandiza kupeŵa dontho la khalidwe. Ndikwanira kukumbukira kukula koyambirira kwa fano.
Lonjezerani chisankhocho, ndipo kenaka lembani zoyambirira zomwe mumayendera.
Monga mukuonera, kukula kwa zosindikizidwa kunasintha, pakusindikizira timapeza chithunzi choposa 12x12 cm of quality.
Kusankha kukonza
Mfundo yosankha ndondomekoyi ndi iyi: Wowona kwambiri ali ndi chithunzicho, ndipamwamba mtengowo ukufunika.
Zida zosindikizidwa (makadi a zamalonda, timabuku, ndi zina zotero), mulimonsemo, chilolezo cha osachepera 300 dpi.
Kwa zojambulajambula ndi zojambulajambula, zomwe owona amayang'ana kuchokera patali pafupifupi 1 - 1.5 mamita kapena kuposerapo, mwatsatanetsatane sichifunikira, kotero mutha kuchepetsa mtengo 200 - 250 ma pixel pa inchi.
Malo osungiramo malonda, omwe owonawo akupitirizabe, angakongoletsedwe ndi zithunzi zosinthika mpaka 150 dpi.
Mabanki akuluakulu a malonda, omwe ali kutali kwambiri ndi owona, kupatula kuwawona mwachidule, adzachita bwino 90 madontho ndi inchi.
Zithunzi zomwe zimapangidwira zojambulazo, kapena zofalitsa chabe pa intaneti, zatha 72 dpi.
Mfundo ina yofunika posankha chisankho ndi kulemera kwa fayilo. Kawirikawiri, ojambula amalingalira mopanda nzeru zomwe zilipo ma pixel pa inchi, zomwe zimabweretsa kuwonjezeka kwakukulu kwa kulemera kwa fano. Tenga, mwachitsanzo, bendera lokhala ndi miyeso yeniyeni ya 5x7 mamita ndi chisankho cha 300 dpi. Ndizimenezi, chikalatacho chidzafika pafupifupi 60000x80000 pixels ndipo "kukoka" pafupifupi 13 GB.
Ngakhalenso zipangizo za kompyuta yanu zimakulolani kugwira ntchito ndi fayilo ya kukula kwake, ndiye kuti nyumba yosindikizira sizingavomereze kuti izitenga. Mulimonsemo, muyenera kufunsa zofunikira.
Izi ndizo zonse zomwe mungathe kudziwa potsata zithunzi, momwe mungasinthire, ndi mavuto omwe mungakumane nawo. Onetsetsani momwe chisankho ndi khalidwe la zithunzi pazenera pazowunikira ndikusindikizira, komanso madontho angapo pa inchi zidzakwanira zosiyana.
