Mukuyang'ana njira yachangu, yosavuta, komanso yothandiza yobera magiredi amitundu pazithunzi pogwiritsa ntchito pulogalamu yaulere? Mu phunziro ili, ndikufotokoza njira yothandiza kwambiri yobera mtundu wa chithunzi pogwiritsa ntchito pulogalamu iliyonse - yaulere kapena yolipira - pogwiritsa ntchito pulogalamu yaulere yosinthira zithunzi Darktable. Njirayi idzagwira ntchito ndi zithunzi za JPEG kapena zithunzi za RAW (Darktable makamaka ndi pulogalamu ya RAW yokonza, koma imatha kuthana ndi mafayilo osiyanasiyana kuphatikizapo ma JPEG).

Mutha kuwonera kanema waphunziroli pansipa, kapena kusuntha modutsa momwe zalembedwera (zopezeka m'zilankhulo 30+ pogwiritsa ntchito chizindikiro cha zilankhulo chomwe chili kumanzere kumanzere kwa tsambali).

Gawo 1: Lowetsani Zithunzi Zanu Mumdima

Choyamba, muyenera kubweretsa zithunzi zomwe mukufuna kugwiritsa ntchito mu Darktable.

Kuti muchite izi, pitani ku tabu yanu ya Lighttable ngati mulibe kale (nthawi zambiri mumatengedwera ku tabu iyi mwachisawawa mukatsegula Darktable - dinani "zopepuka", zolembedwa zobiriwira pachithunzi pamwambapa). Mukakhala pa Lighttable tabu, dinani "kulowetsa" muvi wotsikira (muvi wofiyira pachithunzi pamwambapa). Dinani "Chithunzi" (muvi wabuluu) kuti musankhe zithunzi kuchokera pakompyuta yanu.

Pitani ku chikwatu pa kompyuta yanu pomwe zithunzi zanu zimasungidwa (kwa ine, zithunzi zanga zili mufoda yanga yotsitsa). Dinani pa chithunzi chomwe mukufuna kusankha, kenako gwirani kiyi yosinthira ndikudina pazithunzi zina zilizonse zomwe mungafune kusankha ngati mukusankha zithunzi zingapo kuchokera pafoda yomweyi (mivi yofiyira pachithunzi pamwambapa ikuwonetsa zithunzi zitatu zomwe ndatsegula pa phunziroli. ). Zithunzi zanu zikasankhidwa, dinani batani la "Open" pansi pazokambirana (muvi wabuluu).

Mudzawona zithunzi zonse zomwe ndikugwiritsa ntchito pachitsanzo ichi ndi ma JPEG, koma mutha kugwiritsanso ntchito mafayilo aliwonse omwe amathandizidwa ndi Darktable.

Zithunzi zanu nthawi zambiri zimatsegulidwa pagawo la Darkroom (lomwe lili ndi zobiriwira pachithunzi pamwambapa), ndipo ngati mutatsegula zithunzi zingapo zidzawonetsedwa ngati tizithunzi zomwe zimatchedwa "Filmstrip" kumunsi (muvi wofiyira). Mutha kudina kawiri pazithunzi zilizonse kuti mutsegule chithunzicho pagawo la Darkroom - zomwe zikutanthauza kuti ndiye chithunzi chomwe mukugwira ntchito.

Gawo 2: Yambitsani Mapu a Mapu amtundu

Tsopano popeza tili ndi zithunzi zomwe tikufuna kugwiritsa ntchito izi zatsegulidwa kukhala Darktable, tifuna kuyambitsa gawo la "Color Mapping" pachithunzichi chomwe tikubera mtunduwo.

Kuti ndichite izi, ndikupita ku tabu ya "Zotsatira" (muvi wofiyira pachithunzi pamwambapa - kuyerekeza kuti mukugwiritsa ntchito Darktable 3.4 kapena mtsogolomo. M'matembenuzidwe akale a Darktable, gawoli linali pa "Color").

Mukakhala mu tabu iyi, mudzafunika kutsika pansi (pogwiritsa ntchito mipukutu yomwe ili kumanja kwenikweni - muvi wofiyira pachithunzi pamwambapa) kuti mupeze gawo la "Mapu a Mitundu". Mukachipeza, dinani gawo ili kuti mutsegule (muvi wobiriwira).

Mukadina gawo ili kuti muyitsegule, ikuyenera kukula monga momwe tawonetsera pachithunzi pamwambapa. Chizindikiro cha "mphamvu" chikuyenera kuwonetsedwa, kuwonetsa kuti chatsegulidwa. Ngati, pazifukwa zilizonse, chithunzichi sichinawonetsedwe, dinani kuti chikhale chogwira ntchito (muvi wofiyira).

Mudzawona kuti pali madera awiri mu gawoli, "magulu oyambira" ndi "magulu omwe amatsata," komanso kuti madera onsewa ali ndi magulu (omwe afotokozedwa mobiriwira pachithunzi pamwambapa). Madera awa adzakhala komwe mitundu yathu ya zithunzi za "source" ndi mitundu ya zithunzi "zofuna" zimawonekera. Chithunzi chochokera ndi chithunzi chomwe tikubera mtunduwo (chithunzi chachikulu pachithunzi pamwambapa), ndipo chithunzi chomwe tikufuna ndi chithunzi chomaliza pomwe tikhala tikuwonjezera mtundu womwe tidaba pachithunzi choyambirira (chilichonse cha zithunzi zowonetsedwa ndi muvi wabuluu pachithunzi pamwambapa - izi ndizithunzi zomwe mukufuna).

Batani la "aquire as source" "lidzaba" mitundu kuchokera pa chithunzi chomwe chachokera, ndipo batani la "acquire as target" liwonetsa mitundu ya chithunzi chomwe mukuchisinthanitsa nacho.

Pansi pa gridi ya "source clusters" ndi "target clusters" pali masilayidi atatu. "Nambala yamagulu" slider (muvi wabuluu) imakupatsani mwayi wowonjezera kapena kuchepetsa kuchuluka kwamagulu amitundu omwe mukugwiritsa ntchito kupanga mapu amitundu yomwe mumayambira ndi zithunzi zomwe mukufuna. Zomwe muyenera kudziwa pazakhazikitsidwe izi ndikuti kuchuluka kwa nambalayi kumachulukira, m'pamene mukutenga mitundu yambiri pachithunzi chilichonse ndipo motero mitunduyo idzakhala yosiyana. Zotsatira zake, zotsatira za "color grading" zidzakhala zobisika pamapeto pake. Kumbali ina, chiwerengerochi chikatsika, padzakhala mitundu yocheperako yomwe imagwiritsidwa ntchito popanga zotsatira zake ndipo zotsatira zake zidzakhala zamphamvu.

Apanso - chiwerengero chapamwamba chamagulu chimapanga zotsatira zowoneka bwino, ndipo chiwerengero chochepa chamagulu chimapanga mphamvu yamphamvu.

Chotsetsereka chamtundu (muvi wobiriwira) chimatsimikizira momwe mitundu yachithunzichi imasinthidwira ndi mitundu yachithunzicho. Slider ikakhazikitsidwa ku 100%, izi zikutanthauza kuti mitundu yowoneka bwino kuchokera pa chithunzi chomwe mukufuna idzasinthidwe ndi mitundu yowoneka bwino kuchokera pachithunzichi. Mwachitsanzo, ngati kufiira ndi mtundu womwe umawonekera pachithunzichi, ndipo mtundu wobiriwira ndi womwe umakonda kwambiri pachithunzi chomwe mukufuna, ndiye kuti mtundu wobiriwira womwe umakonda kusinthidwa ndi wofiira kwambiri. Pamene slider iyi yakhazikitsidwa ku 0%, zofanana mitundu pakati pa gwero ndi chandamale zithunzi zidzasinthidwa.

Pomaliza, slider yomaliza, slider ya "Histogram Equalization" (mzere wofiira) imakulolani kuti mupange ma histograms a zithunzi ziwiri zofanana. Kunena mwaukadaulo, izi zikutanthauza kuti kusiyanitsa kwa ma toni pazithunzi ziwirizi kupangidwa mofanana kwambiri. Zambiri pa izi pambuyo pake.

Khwerero 3: Pezani ndi Kuyika Mitundu ya Kubera Makalasi Amtundu

Tsopano popeza takhala ndi gawo la Mapu amitundu yoyatsidwa ndipo tikudziwa kuti gawo lililonse la gawoli ndi la chiyani, tsopano titha kuba magiredi amtundu kuchokera kugwero lathu ndikuwonjezera pa chithunzi chomwe tikufuna.

Choyamba, mudzafuna kuyika mtengo wa "nambala yamagulu" ndi "color dominance" slider. Ndikupangira kupita ndi mtengo wa "3" pamagulu angapo. Mutha kuyika chowongolera chamtundu pamtengo uliwonse womwe mungafune kutengera zomwe ndapereka pamwambapa za slider iyi.

Ndikakhazikitsa zomwe ndikufuna, ndikanikizani batani la "peza ngati gwero" (muvi wofiyira pachithunzi pamwambapa). Tsopano muwona kuti gulu langa la "source clusters" (muvi wobiriwira) ladzaza ndi mitundu. Iyi ndi mitundu yomwe tigwiritse ntchito poyika mitundu yathu.

Tsopano popeza tili ndi mitundu yathu yoyambira, dinani kawiri pa chithunzi chomwe mukufuna kugwiritsa ntchito chithunzithunzi chamndandanda wafilimu wa chithunzicho (muvi wofiyira pachithunzi pamwambapa). Izi zidzatsegula chithunzicho mu tabu ya Darkroom. Yang'anani mmbuyo kupita ku gawo la Mapu amtundu. Mutuwu ukhoza kukhala wopanda kanthu kenanso (mwachitsanzo, mitundu yamagulu amitundu sikuwoneka). Ingodinani batani/chithunzi cha "kukonzanso" (muvi wobiriwira) ndipo mitundu yoyambira yomwe mwasankha pa chithunzi chanu idzabweranso.

Mitundu yanu ya "source clusters" ikadzabweranso, dinani batani la "acquire as target". Izi zidzadzaza gululi "chandage clusters" yokhala ndi mitundu kuchokera pazithunzi zomwe mukufuna. Awa ndi mitundu yomwe idzasinthidwe ndi mitundu yoyambira. Mukayang'ana chithunzi chomwe tikufuna, mudzachiwona chili ndi mtundu wofanana kwambiri ndi chithunzi chathu choyambirira.

Tsopano mutha kugwiritsa ntchito slider ya "equalize histogram" (muvi wofiyira) kuti musinthe histogram ya chithunzi chomwe mukufuna, kuti chiwoneke chofanana ndi chithunzi chomwe chachokera.

Monga mukuwonera pachithunzi pamwambapa, mtundu watsopano wamitundu yachithunzi chomwe mukufuna sikuwoneka bwino - khungu limawoneka lofiira kwambiri.

Mutha kukonza izi nthawi zonse pobwerera ku chithunzi choyambira, kusintha "nambala yamagulu" ndi "color dominance" slider kumitengo yatsopano, ndikudina batani la "acquire as source", ndikubwerera ku chithunzi chomwe mukufuna. Mukakhala pachithunzi chomwe mukufuna, dinani batani la "reset" kachiwiri, kenako dinani "pezani ngati chandamale." Izi zidzasinthanso mitundu yanu, koma ndi zoikamo zosiyana pang'ono ndi zotsatira zosiyana. Kuti tifotokoze momveka bwino - bwerezani zomwe zafotokozedwa m'nkhaniyi, ndikusinthira makonda mpaka mutapeza mtundu womaliza womwe mumakonda.

Pamwambapa pali chitsanzo chakusintha makonda kuti mupeze zotsatira zosiyana. Mu chitsanzo ichi, ndinagwiritsa ntchito masango 4 kuti ndiwonetsere bwino kwambiri. Ndinasinthanso slider ya histogram equalization kuti ikhale pamwamba pa 60%.

Ndizo za phunziro ili! Mutha kuwona zina zanga Maphunziro osavuta patsamba langa, kapena penyani chilichonse changa GIMP or Maphunziro a Inkscape.
