Ena a inu mwina simunamvepo kapena simunamvepo za njira yojambulira yotchedwa "Exposure Bracketing." Apa ndi pamene mumauza kamera yanu kuti mukufuna kutenga mitundu ingapo ya chithunzi chomwecho pogwiritsa ntchito mawonekedwe osiyanasiyana. Ndi njirayi, mupanga chithunzi chimodzi chokhala ndi mawonekedwe otsika (ie chithunzi chakuda), chithunzi chimodzi chokhala ndi pakati, ndi chithunzi chimodzi chokhala ndi mawonekedwe apamwamba (ie chithunzi chowala). Makamera osiyanasiyana ali ndi mphamvu zosiyana, koma apa pali chitsanzo.

Ndi Canon 7D yanga, ndimatha kupeza "Exposure Comp./AEB Setting" (AEB imayimira Auto Exposure Bracketing) kudzera pa menyu yayikulu ndikugwiritsa ntchito kuyimba kwanga kwakukulu kuti ndikhazikitse mawonekedwe otsika komanso mtengo wowonekera. Mwachikhazikitso, palinso mtengo wapakati wowonekera. Chifukwa chake, pamapeto pake, kuyika uku kutulutsa mawonekedwe atatu osiyana a chithunzi chomwecho (poganiza kuti ndakhazikitsidwa pa tri-pod - mumayenera kukanikiza batani la shutter katatu kuti mupange chithunzi chilichonse chokhala ndi bulaketi). Makamera ena amakulolani kuti mujambule zithunzi zopitilira zitatu zokhala ndi mabulaketi.

Zonsezi ndizofunikira chifukwa zithunzi zomwe zili m'mabulaketi zimakulolani kuti muphatikize zowonetsera zitatuzo pamodzi panthawi yokonza zithunzi kuti mupange "HDR," kapena High Dynamic Range, Image. Pophatikiza zithunzi zitatuzi ndi mawonekedwe osiyanasiyana palimodzi, mumapeza kuyatsa kwabwino kwambiri pazithunzi zonse. Mwachitsanzo, mutha kudziwa zambiri kuchokera kumlengalenga kowala komanso kutsogolo kowoneka bwino nthawi yomweyo.

Mukatenga zithunzi zomwe zili m'mabulaketi ndi kamera yanu ndikuzitumiza ku kompyuta yanu, muyenera kuchita chinthu chotchedwa "HDR Merge" kuti muyambe kugwiritsa ntchito bwino izi. Mawuwa akutanthauza kungounjika zithunzi zomwe zili m'mabulaketi pamwamba pazzanu, ndikusintha zithunzi zojambulidwa pamodzi kuti mutulutse zabwino zonse. Mu Darktable, pali njira yosavuta yochitira ntchitoyi.

Yambani ndikutsegula pulogalamu ya Darktable pa kompyuta yanu (Ndinatsegula Darktable pogwiritsa ntchito bar yofufuzira mu Windows, yomwe ikuwonetsedwa pachithunzi pamwambapa - ngakhale ambiri a inu mutha kugwiritsa ntchito njira yachidule ya Desktop).

Yendetsani ku tabu ya Lighttable (muvi wofiyira pachithunzi pamwambapa) ngati simunatengedwe kumeneko mwachisawawa. Apa ndipamene mungalowetse ndikusakatula zithunzi zomwe mwajambula ndi kamera yanu.

Kumanzere kwa zenerali, pita ku gawo lotsitsa la "Import" (muvi wabuluu pachithunzi pamwambapa) ndikudina muvi kuti mukulitse. Muwona njira zina zogulitsira zithunzi zanu - sankhani "Foda" kuti mulowetse chikwatu chonse cha zithunzi (muvi wachikasu pachithunzi pamwambapa), kapena sankhani "Chithunzi" kuti mungolowetsa zithunzi zomwe mwasankha kuchokera mufoda (mutha kusankha zithunzi zingapo. pogwiritsa ntchito kiyi ya shift kapena ctrl mukadina pazithunzi zomwe mukufuna kuitanitsa - ndimapitilira kuitanitsa mwatsatanetsatane mwatsatanetsatane wanga. Zofunika Zosintha Zithunzi mu Darktable njira).

Kwa ine, ndigwiritsa ntchito njira ya "Foda" ndikulowetsa zithunzi zonse mkati mwa chikwatu changa cha Aug 11 2020 (muvi wofiyira pachithunzi pamwambapa). Ndidina kamodzi pa fodayo ndikudina batani la "Open" kuti mulowetse zithunzizo (muvi wabuluu).

Zithunzi zanga zikatumizidwa kunja, ndimatha kuzidutsa pogwiritsa ntchito gudumu langa la mbewa mpaka nditapeza zithunzi zomwe ndikufuna kugwiritsa ntchito pophatikiza HDR yanga. Kwa ine, ndili ndi kamera yanga yokhazikitsidwa kuti nditenge chithunzi cha RAW (chomwe chimapanga fayilo ya .CR2 - muvi wabuluu pachithunzi pamwambapa) ndi chithunzi cha JPEG (muvi wachikasu) - kotero chithunzi chilichonse chojambulidwa ndi kamera yanga ndi yobwerezedwa. Ena a inu mutha kukhala ndi chithunzi CHOKHA, kapena kukhala ndi chithunzi cha JPEG YOKHA. Mulimonsemo, njira iyi idzakuthandizani.

Kwa ine, ndiyika mbewa yanga pachithunzi choyambirira chomwe ndikufuna kugwiritsa ntchito kuphatikiza kwa HDR ndikudina (muvi wofiyira pachithunzi pamwambapa). Izi zidzasankha chithunzi. (Ndinapita ndi mtundu wa RAW - kapena fayilo ya CR2 - ya chithunzi changa m'malo mwa JPEG).

Kenako, ndigwira kiyi ya ctrl ndikudina pa chithunzi chapansi (chomwe ndi chithunzi chakuda - muvi wofiyira pachithunzi pamwambapa).

Pomaliza, ndikugwirabe kiyi ya ctrl, ndidina pa chithunzi chowoneka bwino kwambiri (ie chithunzi chowala kwambiri - muvi wabuluu pachithunzi pamwambapa). Tsopano ndiyenera kukhala ndi zithunzi zitatu zosankhidwa (zithunzi zina ziwiri zosankhidwazo zikusonyezedwa ndi muvi wofiyira pachithunzi pamwambapa) - chilichonse chili chithunzi chofanana (ndinatengadi chithunzichi pamatatu) koma ndi mawonekedwe osiyanasiyana.

Pangani HDR Merge DNG Image Darktable Tutorial

Zithunzi zanga zonse zikasankhidwa, ndipita kumanja kwawindo la Lighttable kupita kumalo otsika olembedwa "zithunzi zosankhidwa" (muvi wachikasu) ndikudina kuti ndikulitse kutsika uku. Kenako, ndidina batani lotchedwa "Pangani HDR" (muvi wofiyira pachithunzi pamwambapa - zindikirani: batani ili lingowoneka ngati muli ndi zithunzi zambiri zomwe mwasankha. Mudzazindikiranso, mukayika mbewa yanu pamwamba pake, kuti batani likuti "Pangani chithunzi chosinthika kwambiri kuchokera pazithunzi zosankhidwa.").

Mukadina batani Pangani HDR, Darktable iyamba kugwira ntchito yophatikiza zithunzizo (pakona yakumanzere kwa Darktable idzanena "kuphatikiza zithunzi 3" - muvi wabuluu pachithunzi pamwambapa - kapena zithunzi zambiri zomwe mukuphatikiza).

Kuphatikiza kukatha, muyenera tsopano kuwona chithunzi chatsopano (muvi wofiyira pachithunzi pamwambapa) chopangidwa kumayambiriro kwa zithunzi zitatu zomwe mwasankha kuti muphatikize. Chithunzicho chikhoza kuwoneka chakuda komanso chodetsedwa poyamba, ngakhale mutha kukonza izi pogwiritsa ntchito tabu ya Darkroom. Mukadina pachithunzichi ndikuyendetsa mbewa yanu pamwamba pake, mudzawona chithunzicho tsopano ndi fayilo ya ".DNG". DNG imayimira "Digital Negative" ndipo ndi mtundu wa fayilo womwe umagwiritsidwa ntchito popanga kuphatikiza kwa HDR.

Mukadina kawiri pa chithunzi cha DNG, chidzatsegulidwa pa tabu ya Darkroom (yomwe ili yachikasu pachithunzi pamwambapa) komwe mungasinthire. Chifukwa chithunzichi chili ndi zithunzi zitatu zosiyana zoyikidwa pamwamba pa chinzake, kusintha komwe mumapanga pogwiritsa ntchito ma module a Darktable kumapanga zotsatira zosiyana ndi zomwe mumazolowera mukangosintha chithunzi chimodzi.

Ndizo za phunziro ili! Ngati mukufuna kudziwa zambiri za Darktable, onani wanga Zofunika Zosintha Zithunzi mu Darktable kumene ndimafotokoza zofunikira za momwe mungagwiritsire ntchito pulogalamuyi, komanso ma modules abwino kwambiri okonzekera kapena kukonza zithunzi zanu za RAW. Mukhozanso kuyang'ana wanga Maphunziro amakanema amdima kapena zolemba zothandizira!
