Kugwiritsa ntchito zonona pazithunzi kuli ndi zabwino zambiri. Zimathandizira kubwezeretsanso tsatanetsatane wa chithunzi chanu chomwe chidatayika panthawi yopanga ma digito, makamaka m'mphepete mwa mitu kapena zinthu zomwe zili pachithunzi. Itha kuthandizanso kukonza zithunzi zomwe zidatuluka movutikira mukamajambula chifukwa cha kamera yogwedezeka, kuphonya, kapena zifukwa zina zambiri. Pamapeto pake, kuwonjezera zowongoka panthawi yokonza zithunzi ndi njira yosavuta yosinthira mawonekedwe anu ndikuwongolera mawonekedwe azithunzi zanu.

Pali njira zingapo zonolera zithunzi zanu pogwiritsa ntchito GIMP, koma njira yoyesera komanso yowona yochitira izi ndikugwiritsa ntchito fyuluta ya Sharpen (Unsharp Mask). Ndikambirana momwe mungagwiritsire ntchito fyulutayi mozama m'nkhaniyi, komanso ndikupereka malangizo panjira yokuthandizani kuti mukhale ndi zithunzi zakuthwa nthawi zonse mu GIMP.

M'ndandanda wazopezekamo

Nthawi Yomwe Mungagwiritsire Ntchito Kunola Panthawi Yosintha Zithunzi

Poyamba, ndikupangira kunola zithunzi zanu kumapeto kwa kusintha kwa kachitidwe kanu, kutanthauza kuti mutatha kukonza, kukhudzanso, ndikusinthanso kukula kwake kapena kusitula chithunzicho. Izi zimapewa kukulitsa tsatanetsatane wazinthu zomwe mukufuna kuzichotsa pachithunzicho (mwachitsanzo makwinya kapena zinthu zakale) ndikuwonetsetsanso kuti kuwongola komaliza ndikokwanira kwa chithunzi chomaliza.

Momwe Mungayikitsire Sefa ya Sharpen (Unsharp Mask).

Kumbukirani kuti fyulutayi idapangidwa kuti ipewe kukulitsa zilema kapena phokoso pazithunzi zanu, ndiye zili bwino ngati chithunzicho chili ndi zolakwika ikafika nthawi yoti kunole.

Kuti mugwiritse ntchito fyuluta, onetsetsani kuti chithunzi chanu ndichosanjikiza chogwira ntchito pagawo lanu la Layers (muvi wabuluu pachithunzi pamwambapa), kenako pitani ku Zosefera> Sinthani> Lirani (Unsharp Mask) - yowonetsedwa ndi muvi wofiyira pachithunzichi.

Izi zidzabweretsa kukambirana kwa "Sharpen (Unsharp Mask" (yofotokozedwa mu buluu pachithunzi pamwambapa), yomwe ili ndi masiladi atatu pamodzi ndi zina zowonjezera zowonjezera ndi zoikamo. chochokidwa (muvi wofiyira) musanayambe kusintha makonda.Izi zidzatsimikizira kuti mukuwona chithunzithunzi cha chithunzi chanu pamene mukunola.

Radius Slider

Chotsetsereka choyamba, "Radius," (muvi wofiyira pachithunzi pamwambapa) chimakupatsani mwayi wowonjezera kapena kuchepetsa malo mbali zonse za "m'mphepete" mwatsatanetsatane pachithunzi chanu kuti mukule. M'mphepete ndi mafotokozedwe ozungulira pachithunzi - monga mawonekedwe a maso kapena nsidze za mutu, mizere yatsitsi la mutu, kapena nsagwada ya mutu wa mutu (mivi yabuluu pachithunzichi). Kwenikweni, malo aliwonse pomwe ma pixel amasintha mphamvu kapena kusiyanitsa kwawo ndi m'mphepete. Popeza fyulutayi imagwira ntchito powonjezera kusiyanitsa mozungulira m'mphepete, chowongolera cha Radius ndichofunika chifukwa chimakulolani kuyika kukula kapena kung'ono kwa malo omwe mukufuna kukulitsa m'mphepete mwa chithunzi chanu.

Kuwonetsa slider iyi ikugwira ntchito ndiyothandiza kwambiri tikakulitsa mtengo wa slider yachiwiri, ndiye tibwereranso ku Radius slider. Ndikulonjeza kuti zidzamveka kwa inu kumapeto kwa nkhaniyi.

Mtengo Slider

Chotsetserekera chotsatira, "Nambala," (muvi wofiyira pachithunzi pamwambapa) imakupatsani mwayi wowonjezera kapena kuchepetsa kuchuluka kwa kunola komwe kumagwiritsidwa ntchito pachithunzi chanu. Mukayika mtengo wa slider iyi, ndiye kuti kukulitsa kwake kumakhala kolimba. Mtengowo ukakhala wotsika, zotsatira zake zimakhala zofooka kwambiri ndipo motero padzakhala kunyowa kochepa komwe kumagwiritsidwa ntchito pa chithunzi chanu. Ngati ndidina ndikukoka chotsetsereka ichi kuti muwonjezere mtengo mpaka pakati pa 20 ndi 25 (muvi wabuluu pachithunzichi), mudzawona kulimba kwake kudzakhala kokulirapo ndipo tiwona zambiri pachithunzi chathu. Kuchulukitsa mtengo wa "Ndalama" kwambiri kumawonjezeranso phokoso pachithunzichi, chomwe mutha kuchiwona mukamayandikira.

Ngati, kumbali ina, nditsitsa mtengowo ku "0" (muvi wofiyira pachithunzichi), zikuwoneka ngati palibe kuwola pa chithunzi chathu.

Nthawi zambiri, kukula kwa chithunzi chomwe mukuchikonza, m'pamenenso mutha kuwonjezera "Ndalama" slider popanda kuchulutsa. Kwa ine, chithunzi changa chikupitilira ma pixel 5000 m'lifupi ndi ma pixel 3400 muutali, chomwe ndi chithunzi chachikulu, kotero nditha kuwonjezera kuchuluka kwa slider pang'ono ndikupeza zotsatira zowoneka bwino. Ngati mukusintha chithunzi chaching'ono (ie 1280×720), mungafune kusunga "Ndalama" yokhazikitsidwa pamtengo wotsika kuti mupewe kunola kwambiri.

Ndi kuchuluka kwa slider kukweza pang'ono (muvi wofiyira), tiyeni tiwonenso chowongolera cha Radius kuti tiwone momwe chingasinthire kuwongolera kwa chithunzi chanu. Mwachikhazikitso, mtengo wa slider umayikidwa ku 3. Ngati ndiyamba kuonjezera mtengo wa slider (ndinapita kuzungulira 7.5 mu chithunzi - muvi wabuluu), mudzawona kuti m'mphepete mwa tsatanetsatane wa chithunzi changa chimayamba. kukhala ndi kusiyana kochulukira ndi kukhala mdima m'mawonekedwe. Mitundu yachifaniziro changa iyambanso kuwonetsa zizindikiro zosokoneza. (Zindikirani: zowonera izi ndizovutirapo pang'ono kuziwona pachithunzi apa popeza ndazikulitsa patsamba / nkhani).

Ngati ndipitiliza kukulitsa mtengowu kuzinthu zina monyanyira, monga mtengo wozungulira 50, m'mphepete mwake tsopano zikhala ndi zosiyana kwambiri, mitunduyo idzakhala yopotoka kwambiri, ndipo chithunzi chonse chikuwoneka chosawoneka bwino.

Apanso, ngati mukugwiritsa ntchito chithunzi chaching'ono, mutha kuyamba kuwona zotsatirazi posachedwa mukasintha ma slider.

Ndikupangira kusunga mtengo wanu wa Radius kukhala wotsika mtengo, ndikusintha slider ya Ndalama mpaka musangalale ndi kuchuluka kwa kunola komwe kumagwiritsidwa ntchito pa chithunzi chanu.

Kuphatikiza apo, onetsetsani kuti mukuyandikira mpaka 100% ya mtengo wa zoom kuti muwone bwino phokoso lililonse lomwe lingapangidwe kudzera pakunola, makamaka ngati mukufuna kusindikiza chithunzicho. Ngati mutumiza kwinakwake komwe chithunzicho chidzatsindikitsidwa, izi sizingakhale zazikulu. Mutha kupeza kuti chithunzicho chili ndi phokoso lambiri mukachiyang'ana pafupi ndipo mungafune kusintha makonda anu kuti muchepetse phokoso ndikukulitsa kukulitsa.

Threshold Slider

Slider yomaliza ya fyulutayi ndi "Threshold" slider. Slider iyi imakulolani kuti musinthe pomwe kusintha kwa ma pixel kumatengedwa ngati "m'mphepete." Malinga ndi a GIMP, kukulitsa mtengo wa slider iyi “kuteteza madera osinthasintha ma tonal kuti asawole, komanso kupewa kupangika kwa zilema kumaso, kumwamba kapena pamwamba pamadzi.” Mwa kuyankhula kwina, ngati mutayamba kuwona kukulitsa mozungulira zilema kapena m'madera omwe pali kusintha kosalala kwa mitundu (aka osati m'mphepete), mukhoza kuwonjezera mtengo wa slider iyi ndipo idzachotsa kukulitsa kumadera amenewo.

Ndikabweretsa mtengo wa slider iyi kuti ndiwonetse momwe zikuyendera (muvi wofiyira), muwona kuti chithunzi changa chikuwoneka chodumphira chonse chifukwa GIMP ikuchepetsa kuchuluka kwa m'mbali zomwe zimawongoleredwa pachithunzi changa. GIMP isungabe kuthwa pang'ono m'mbali zotchulidwa (monga maso a mutu wanga).

Pachithunzichi sindikufunika kusintha poyambira, kotero ndikokera mtengowo kubwerera ku 0.

Gawani mawonedwe ndikuwonjezera Zokonzedweratu

Ngati mukufuna kuwona momwe chithunzi chanu chikuwonekera kale komanso pambuyo pakukulitsa, mutha kudina "Gawani Chiwonetsero" pakona yakumanja kwa zokambirana (muvi wofiyira) kuti muwone kufananitsa mbali ndi mbali. Mukhozanso kusuntha mzere wa madontho apinki kuti muyikenso chithunzithunzi.

Ngati mukufuna kuwonjezera makonda anu apano monga momwe adakhazikitsira mkati mwa GIMP, dinani chizindikiro "+" pamwamba pa zokambirana (muvi wofiyira). Kenako mutha kutchula zomwe mudapanga kale (ndinatchula zanga "Cowgirl Edit" - muvi wabuluu) ndikudina Chabwino kuti musunge zomwe mwakhazikitsa (muvi wobiriwira).

Tsopano mukadina "Presets" dropdown (muvi wofiyira) mudzawona zosungira zanu zosungidwa pansi pamndandanda (muvi wobiriwira). Kudina pa preset kuyika makonda anu apano pa chithunzi chilichonse chomwe mukugwiritsa ntchito.

Mukakondwera ndi zokonda zanu, dinani Chabwino kuti mugwiritse ntchito kuthwa kwanu pachithunzi chanu.

Ndizo za phunziro ili! Ngati mukufuna kudziwa bwino GIMP, mkonzi wazithunzi waulere, mutha kulembetsa mu my GIMP 2.10 Masterclass pa Udemy. Mukhozanso kufufuza zambiri Maphunziro a GIMP patsamba langa.
