Pali njira zambiri zosinthira chithunzi mu GIMP - zina zimakhala zotopetsa, ngakhale zolondola, kuposa zina. Mu phunziro ili, ndikuwonetsani zomwe ndikuganiza kuti ndi imodzi mwa njira zosavuta komanso zolondola zosinthira chithunzi (kapena kusintha mtundu uliwonse pa chithunzi). Ndikhala ndikugwiritsa ntchito GIMP 2.10.22 paphunziroli, lomwe ndi mtundu waposachedwa kwambiri wa GIMP panthawi ya phunziroli.

Mutha kuwonera kanema wamaphunzirowa pansipa, kapena kudumpha kuti muwerenge mtundu wa Help Article.

M'ndandanda wazopezekamo

Khwerero 1: Tsegulani Chithunzi Chanu mu GIMP

Pongoyambira, nditsegula chithunzi chomwe ndikufuna kugwiritsa ntchito paphunziroli (lomwe mutha kutsitsa kwaulere ku Pexels ngati mukufuna kutsatira). Nditha kutsegula chithunzi mu GIMP popita Fayilo> Tsegulani kapena kungodinanso ndikukokera chithunzi changa kuchokera pakompyuta yanga pawindo la GIMP (monga momwe mivi yofiyira yasonyezera, kutsatira njira ya madontho obiriwira pachithunzi pamwambapa).

GIMP nthawi zambiri imakufunsani ngati mukufuna "kusintha" chithunzicho kukhala malo amtundu wa sRGB wa GIMP, kapena "sungani" mbiri yakale yachithunzicho. Gawo ili lili ndi inu, koma ndimakonda kupita ndi "convert."

Khwerero 2: Tsegulani Zochita za Rotate Colours

Chithunzicho chikatsegulidwa mu GIMP, tsopano titha kugwiritsa ntchito chida cha "Rotate Colours" kuti tisinthe chithunzi chathu. Kuti mupeze chida ichi, pitani ku Mitundu> Mapu> Sinthani Mitundu.

Khwerero 3: Zosintha za Source Range

Kukambitsirana kwa "Rotate Colours" kumakhala ndi mawilo amitundu ingapo ndi ma slider angapo. Pafupi ndi pamwamba pa zokambirana pali gawo lotchedwa "Source Range" (muvi wofiyira pachithunzi pamwambapa). Derali limakupatsani mwayi wosankha mtundu womwe mukufuna kusintha. Chifukwa chomwe chida ichi chimagwirira ntchito ndi chakuti mitundu yachithunzi sikhala yamtundu umodzi wokha, ngati nthawi zonse. Nthawi zambiri amakhala amitundu yosiyanasiyana okhala ndi mithunzi yosiyanasiyana, machulukitsidwe, komanso ngakhale ang'onoang'ono amitundu. Posankha mitundu yofananira ndi fyulutayi, mutha kusankha bwino mitundu yamtundu umodzi kudutsa ndi chithunzi ndikusintha mitunduyo ndi mitundu yatsopano - potero mumapanga mawonekedwe owoneka bwino.

Mudzawona kuti gudumu lamtundu mkati mwa madera a Source Range ngati mivi iwiri yomwe imasinthasintha pamalo amodzi. Mivi iyi imasonyeza chiyambi ndi mapeto a mitundu yomwe mukusankha. Mutha kudina paimodzi mwa mivi iyi kuti mukulitse kapena kuchepetsa mtundu womwe mukusankha, kapena dinani pakati pa miviyo kuti muzungulire mtundu wonsewo kuzungulira gudumu (zomwe zimapangitsa kuti mitundu yatsopano isankhidwe). Pankhaniyi, ndikufuna kusankha mitundu ya buluu yopepuka pachithunzi changa (muvi wobiriwira pachithunzi pamwambapa), kuti ndizitha kuzungulira mivi yonse iwiri kuzungulira gudumu lamtundu mpaka ndikafike kudera lomwe buluu amakhala.

Monga ndidanenera kale, ndithanso kukulitsa kapena kuchepetsa kuchuluka kwake podina ndi kukoka muvi umodzi wokha panthawi imodzi. Pamenepa, ndikufuna kusankha kagawo kakang'ono koyandikana ndi kuwala kwabuluu/cyan. Chifukwa chake, ndikokera muvi uliwonse (mivi yofiira pachithunzi pamwambapa) pafupi ndi mtundu uwu. Pamene ndikuchita izi, mudzawona kuti tipeza mthunzi wosiyana pang'ono wa tsitsi lachikasu pa chitsanzo (zambiri chifukwa chake tsitsi liri lachikasu pompano).

Mivi iyi iliyonse imagwirizana ndi slider kumanzere. Chifukwa chake, muvi umodzi umafanana ndi slider "Kuchokera" (mivi yofiira pachithunzi pamwambapa), pomwe ina imagwirizana ndi "Ku" (mivi yobiriwira pachithunzi pamwambapa). Mwinamwake mwawonapo pamene ndimatembenuza mivi mozungulira gudumu lamtundu ndikusintha payekhapayekha muvi uliwonse mkati kuti zikhalidwezi zasintha kukhala zatsopano. Chifukwa chake, nditha kusintha ma slider awa podina ndi kukoka mivi yomwe ili pagudumu lamtundu. Komabe, nditha kusinthanso izi pamanja pokoka chotsitsa ndi mbewa yanga, kapena podina pakati ndi gudumu langa la mbewa pamawerengero ndikulemba pamanja mtengo.

Pansi pa zowonera pali zinthu zitatu zowonjezera - bokosi loyang'ana "Clockwise", batani la "Invert Range", ndi batani la "Sankhani Zonse" (lomwe lafotokozedwa mofiira pachithunzi pamwambapa).

Bokosi loyang'ana la "Clockwise" (muvi wofiyira) limasintha mitundu kuchokera mkati mwa mivi iwiri kupita kunja kwa mivi iwiri (muvi wobiriwira). Izi zimangosintha mitundu yomwe mwasankha potembenuza malo mkati mwa miviyo. Mu chitsanzo ichi, mudzawona kuti m'malo mwa tsitsi lachitsanzo ndi maziko omwe amasankhidwa, tsopano nkhope yake ndi maonekedwe ake amasankhidwa. Ndichotsa posankha bokosi ili.

Batani la "Invert Range" (muvi wofiyira) lisintha mtundu wamitundu yanu. Pakali pano, mitundu yamitundu yanu imasankhidwa motsatana ndi wotchi. Potembenuza dongosolo (muvi wobiriwira), zotsatira zake zidzakhala zosiyana pang'ono. Mu chitsanzo ichi, tsitsi lachitsanzo limachoka kuchikasu kupita ku lalanje ndi kusintha pang'ono uku. Ndidinanso "Invert Range" kuti ndibwezerenso mayendedwe motsutsa (ndikubwezeretsa tsitsi lachikasu).

Batani la "Sankhani Zonse" limangosankha mitundu yonse yamitundu. Izi sizothandiza kwambiri pachida ichi, chifukwa chake sindifotokoza mwatsatanetsatane (makamaka, mutha kugwiritsa ntchito fyuluta yamtundu wa hue m'malo mwake).

Khwerero 4: Zosintha za Kopita

Pansi pa gawo la "Source Range" pali "Destination Range" (muvi wofiyira). Gawo ili ndipamene mumasankha mtundu WATSOPANO womwe mukufuna kusintha mtundu wanu wakale. Pakalipano, chifukwa gudumu lamtundu mu gawoli likukhazikika pachikasu (muvi wobiriwira), mitundu yathu yakale (buluu / teal) yasinthidwa kukhala mitundu yatsopano (yachikasu / lalanje). Ichi ndichifukwa chake mtundu wathu pakadali pano uli ndi tsitsi lachikasu / lalanje.

Magudumu amtundu, mivi, masiladi, ndi bokosi loyang'ana / mabatani a gawoli amagwira ntchito mofanana ndi momwe amachitira ndi gawo la Source Range - ngakhale mwachiwonekere makondawa amakhudza mtundu watsopano m'malo mwa mtundu womwe tikuyesera kusintha.

Chifukwa chake, ndikadafuna kuti mtundu wake watsitsi watsopano ukhale wosiyana ndi wachikasu, nditha kudina ndikukokera mbewa yanga mkati mwa mivi yomwe ili pagudumu lamtundu kuti ndiyikenso. Mwachitsanzo, ngati ndiyika mivi iyi pakati pa gawo la magenta la gudumu lamtundu (muvi wofiyira), tsitsi lake limakhala lapinki/magenta.

Zachidziwikire, nditha kukulitsanso kapena kutsitsa mtundu kuti ndipeze mitundu yosiyana pang'ono. Mwachitsanzo, kukulitsa muvi wa "Kuchokera" kunja (muvi wofiira) kumayambitsa mitundu yambiri ya buluu, zomwe zimapangitsa kuti tsitsi lomaliza likhale lofiirira. Ngati ndibweretsa muvi wa "Ku" mkati (muvi wobiriwira), ndikuchepetsa mtundu, tsitsi limakhala lofiirira.

Ngati ndisuntha mbali yonseyi pafupi ndi zofiira (muvi wofiyira), tsitsi tsopano likuwoneka ngati mtundu wa pinki / wofiira.

Khwerero 5: Zosintha za Gray Handling

Pansi pa "Destination Range" pali gawo la "Gray Handling". Apa, mutha kuwuza GIMP kuti ndi mbali ziti za chithunzi chanu zomwe zili zotuwa, ndi zomwe mukufuna kuchita ndi madera otuwa / mitundu. Izi zitha kukhala zothandiza pakuwongolera kutuluka kwamtundu uliwonse kukhala mitundu yosafunikira, kapena kuyambitsa mitundu m'malo otuwa kapena otuwa omwe sanatenge mitundu yatsopanoyo.

Slider ya "Gray Threshold" (muvi wofiyira) imakulitsa kuchuluka kwa mitundu yomwe imaganiziridwa kuti imvi pachithunzichi (pamene mukokera cholowera kumanja), kapena kuchepetsa kuchuluka kwa mitundu yomwe imawonedwa ngati imvi (mukakokera chotsetserekera kumanzere).

"Gray Mode" ndi dontho (muvi wabuluu) womwe umakupatsani mwayi wodziwa zomwe mukufuna kuchita ndi mitundu yotuwa pachithunzichi. "Sinthani ku Izi" isintha mitundu yotuwa mu "Source Range" kukhala mtundu uliwonse womwe mungasankhe pagudumu lamtundu. "Chitani Monga Izi" isintha mitundu yotuwa mu "Source Range" yanu kukhala mtundu womwewo mu "Destination Range" kutengera mtundu womwe mwasankha pa gudumu lamtundu wa Gray Handling.

Kuti ndiwonetse momwe izi zimagwirira ntchito, ndigwira ctrl ndikuwonera chithunzicho ndi gudumu langa la mbewa. Ngati nditsegula "Threshold" (muvi wabuluu), ikani "Gray Mode" kutsika (muvi wobiriwira) kuti "Sinthani ku Izi," ndikusankha mtundu wofiira pa gudumu langa lamtundu (pongodinanso gawolo ndi mbewa yanga. - muvi wofiyira), muwona kuti ma pixel ofiira atsopano amalowetsedwa mu chithunzi changa m'malo omwe ndawasankha ngati imvi. Pankhaniyi, zotsatira zake sizothandiza chifukwa tsopano pali matani a pixel ofiira pakhungu (muvi wachikasu). Komabe, pali zochitika zambiri zomwe izi zingakhale zothandiza - kotero ndikupangira kuyesa ndi chithunzi chanu.

Kumbali ina, ngati ndisintha dontho la Grey Mode kukhala "Chitani Monga Ichi" (muvi wobiriwira), ndiye sunthani mtundu wa gudumu langa la Gray Handling kupita kumtundu umodzi mkati mwa Source Area range (mivi yofiira),' Ndiwona kuti imvi tsopano ipatsidwa mtundu womwewo wa Destination Range womwe mtundu wofananira wa Source Range umapeza (panthawiyi, teal imapatsidwa utoto wofiirira - muvi wabuluu pachithunzi pamwambapa - kotero ma pixel omwe ali pakhungu tsopano amakhala ofiirira - yellow arrow). Izinso sizikuwoneka bwino pachithunzichi, ndiye ndingobweretsa slider pansi mpaka 0 ndikusintha masilayidi a "Hue" ndi "Saturation" kukhala 0.

Zindikirani kuti masilayidi a Hue ndi Saturation amakupatsirani njira yodzisankhira mtundu (mtundu) mu gudumu lamtundu komanso kukula kwa mtunduwo (machulukidwe).

Ndisinthanso pang'ono pa Magwero anga ndi Malo Ofikira, kenako dinani OK (muvi wofiyira) kuti mugwiritse ntchito.

Ndizo za phunziro ili! Ngati munakonda, osayiwala kuyang'ana zanga zina Maphunziro a GIMP, kapena kupeza zambiri pokhala a DMD Premium Member!
