Momwe Mungachepetsere Phokoso Kugwiritsa Ntchito Lightroom 3 Kuchepetsa Phokoso

Chimodzi mwazomwe Jodi adalemba posachedwa pa Tsamba la MCP Facebook zinali zovuta kwa ojambula momwe angachitire ndi zovuta zowunikira. Pazolemba za Jodi, onani ulusi apa, anali pa masewera olimbitsa thupi a mwana wawo wamkazi, ndipo anali ndi malire ndi mawonekedwe ake apamwamba a f / 2.8, ndipo amafunika kuwombera 1 / 300-1 / 500 kuti ayimitse mayendedwe.

Kukhala m'mavuto ofananawo, ndikudziwonera ndekha zomwe anali kutsutsana naye. Monga ukwati wojambula zithunzi ndikukuwuzani momwe zingakhalire zowombera mu tchalitchi choyatsa bwino kapena malo olandirira alendo!

Kupeza kutulutsa kolondola kumafikira pakuphatikizika kwa kabowo, liwiro la shutter, ndi ISO, ndipo zonse zimagwirira ntchito limodzi. Sinthani mtengo umodzi poyimira kamodzi, ndipo muyenera kulipirira posintha chimodzi mwazomwe zidatsalira poyimilira kamodzi.

M'malo mwa Jodi, adamuyendetsa pa 1/300 ndi 1/500 kutengera zomwe zikuchitika, komanso kutsegula kwa f / 2.8, ndipo amafunika kuyimitsanso kowonjezera kamodzi. Ndemanga yanga pa positiyi inali "Bwerani ISO yanu ku 12,800 kapena 25,600 ndikugwiritsa ntchito Lightroom kapena kuchepa kodabwitsa kwa Photoshop positi, ndikuvomereza njere ngati "mtengo" wowombera."

Ndikudziwa kuti ena mwa inu mwakomoka chifukwa chongoganiza zakuwombera ku ISO yapamwambayi, nanga ndi phokoso lanji limenelo ... koma ndikuwonetsani momwe osunthira 5 mu Lightroom 3 akagwiritsidwa ntchito moyenera, angakuthandizeni kuchepetsa phokoso pachithunzi chanu. Pali zotsatsa, ndipo ndidzafotokozeranso. Ndikufuna kupewa zokambirana ngati njere ndi zabwino kapena zoipa pachithunzi; ndi mutu wotsutsana, womwe kwa ine umachokera kuzokonda zaluso pagawo la wojambula zithunzi (ndi kasitomala). Zosavuta, ndikulemba pamaziko akuti muli ndi phokoso la ISO pachithunzi chomwe mukufuna kuchepetsa, ndipo simukudziwa komwe mungayambire.

Kodi phokoso limachokera kuti?
Mukamawombera pang'onopang'ono, sensa ya kamera yanu imayenera kugwira ntchito molimbika kuti "muwone" momwe mukuwombera. Mukasintha ISO mu kamera yadijito, mukusintha kukhudzidwa kwa kamera powunikira kapena kukulitsa kapena kuchepetsa kuchuluka kwa kukulitsa purosesa wa kamera ikugwirizana ndi kuwala komwe kunagwidwa pamene shutter inali yotseguka. Mukamachulukitsa "chizindikirocho", phokoso lomwe mumayambitsa kuyesera kupanga china kuchokera pachabe. Chipale chofewa chomwe mumawona pawailesi yakanema mukamasankha chiteshi chosatulutsidwa ndi zotsatira zakukulitsa kanema wofowoka kapena wosowa.

Kutenga 1: Kuwala pang'ono komwe kumakulitsa = phokoso.
Kutenga 2: Ngati muwombera pa ISO yayikulu, ndikuwala kwambiri, simudzawona phokoso lalikulu. Yesani!
Kutenga 3: Sitikuyesera kuchotsa njere, phokoso chabe. Tirigu ndi chotuluka cha ISO yayikulu, yofanana ndi kanema.

Mwayi kwa ife, anthu ozizira ku Adobe adatipatsa kuchepetsa phokoso ku Lightroom 3 (ndi injini yofananira ndi pulogalamu yatsopano ya Camera Raw ya Photoshop CS5, kuti mutha kugwiritsa ntchito njira yomweyo ya Camera Raw).

Tiyeni tiwone. Jambulani chithunzi pamalo apamwamba kwambiri a ISO omwe kamera yanu imalola (mungafunikire kuloleza kukula kwa ISO mumamenyu ... funsani buku lanu kapena makina osakira omwe mumakonda).

Tsegulani chithunzicho mu Lightroom 3.

Mu Chipinda chowunikira 3 Pangani Module, mupeza fayilo ya tsatanetsatane gawo…

kukuza tsatanetsatane gawo (dinani pa muvi) kuti muwulule anzathu atsopano, otsitsa Mapokoso Ochepera omwe ali pansi pa Kunola gawo.

Nayi chiwonetsero chazithunzi za oterera monga afotokozera Adobe:

Kuwala: Imachepetsa phokoso lowala
Tsatanetsatane: Malo okhala phokoso la Luminance
Kusiyanitsa: Kusiyana kwa kuwala

mtundu; Imachepetsa phokoso lamtundu
Tsatanetsatane: Malo okhala ndi phokoso lamtundu

Kotero tiyeni tiwone iwo mu "kuchitapo". (Onani zomwe ndangochita pamenepo? Ochenjera, inde?)

Kumbukirani, ndikatchula zoterera, ndimangogwira ntchito ndi otsitsa 5 omwe ali mgawo la Kuchepetsa Phokoso ku Lightroom 3. Tiyeni tiwone chithunzi chomwe ndigwire nawo ntchito: (Sindinakonze mtundu uliwonse pachithunzicho, izi ndi zowonekera kunja kwa kamera):

Hubba, hubba! (50mm, f / 11, 1/60 mph) (eya, Pepani amayi, koma ndatengedwa…)

Ndidajambula chithunzi ichi pa Canon 5D Mark II, pa 25,600 ISO. Ndinagwiritsa ntchito chithunzichi chifukwa chili ndi:

1) Khungu
2) Mdima
3) Nyimbo zamkati
4) Mfundo zazikulu
5) Ine (tingalakwitse bwanji?)

Onani phokoso lomwe limawoneka bwino pa kabati yakuda paphewa langa lamanzere. Oy miyala yamtengo wapatali:

Makulitsidwe a 1: 1 akuwonetsa zoyipa zomwe tichotse (osati ine, phokoso):

Pachithunzi pamwambapa, mutha kuwona ma spackling of pixels ofiira, obiriwira, ndi amtambo. Pomwepo pali phokoso lalikulu la ISO. Ndikofunika kuzindikira kuti chifukwa chachikulu chikuwoneka choipa kwambiri ndi chifukwa Ndikhoza kapena sindinabere (ndinatero), posintha fayilo ya mtundu slider kufunika kwa 0 kotero mumatha kuwona phokoso bwino. Lightroom 3's default for slider iyi ndi 25, yomwe ndi poyambira bwino kuti musawone phokoso lamtundu.

Press Z kusinthitsa makulitsidwe a 1: 1 pa chithunzicho, & sankhani malo omwe mungawone magetsi abwino ndi mdima:

mtundu
Yambani posuntha pang'onopang'ono mtundu kutsitsa mpaka phokoso lonse lamtundu litatha, kapena pamlingo wovomerezeka. Mu chithunzi changa, chikuwoneka ngati mtundu slider imagwira ntchito pafupifupi 20. Mukasankha komwe fayilo ya mtundu slider imagwira bwino ntchito lanu chithunzi, pita ku tsatanetsatane wobwerera.

tsatanetsatane
The tsatanetsatane kutsetsereka (pansi pa mtundu slider) amagwiritsidwa ntchito kuti awone ngati tingabwezeretse tsatanetsatane wamitundu. Uku ndikoyesa kwathunthu, ndipo ngati mungakankhire izi tsatanetsatane kutsetsereka kutali kwambiri, mumayambitsanso phokoso ngati mawonekedwe obwezeretsanso pachithunzicho. Panokha, sindidutsa 50 pa izi, koma yesani kutsitsa pazithunzi zanu: kuyambira 0, muziyendetsa pang'onopang'ono, ndi kuwona ngati zikupanga kusiyana kulikonse. Ngati simukuwona kusintha kulikonse, musiyeni 0.

Luminance
Mukakhala okondwa ndikuchepetsa kwa phokoso lamtundu, tulukani mpaka Luminance slider, ndikuyamba kusunthira ichi kumanja. Kumbukirani, akuchedwa ndiye fungulo. Apa ndi pamene diso lanu limabweranso kudzasewera. Muyenera kusankha bwino pakati pa kutayika kwa phokoso / tirigu ndi kutayika kwazithunzi pachithunzi chanu. Mukafika pa sing'anga yosangalala, mutha kupita kowala tsatanetsatane kutsetsereka. Pachithunzi changa, ndine wokondwa ndikutsatsira kwa Luminance 33. Ndidakankhira mpaka ndidayamba kutaya tsatanetsatane pakhungu langa, kenako ndikulibweza kumbuyo.

Chenjezo (nayi malonda omwe ndimakuwuzani kale): ngati mutakankhira Luminance kutsetsereka patali kwambiri, anthu ndi ziweto zidzatuluka zonyezimira ndiye chidole cha atsikana chomwe sichidzakhala dzina, pulasitiki, chopanda pake, chofananira bwino chomwe chili ndi Corvette, ndege yapayokha, & kampira (zomwe sizikugwirizana kwenikweni ndi ndege yabwinobwino). Sindikunena, koma ndikungonena.

"Ndimakonda nkhope ya pulasitiki ..." - Luminance wapita kuthengo!

tsatanetsatane
Kenako, yambani kutsetsereka tsatanetsatane kutsetsereka kumanzere ndi kumanja (chosasintha ndi 50, chomwe nthawi zambiri chimakhala chabwino), kuti muwone ngati mungathe kubwereranso mwatsatanetsatane popanda kuyambiranso phokoso. Apanso, palibe chilinganizo; ndi chithunzi chako, masomphenya ako, kutsitsa kwako. Ndikusiya yanga ndili ndi zaka 50.

siyanitsani
Pomaliza, sungani chojambula Chotsitsa Phokoso kumanja kuti muwone ngati mungapezenso tsatanetsatane. Monga momwe dzinalo limatanthawuzira, chojambulirachi chimayika tsatanetsatane mu chithunzi chanu kutengera kukulitsa kusiyanitsa kowala. Ikhoza kugwira ntchito bwino kuwulula zomwe zidasinthidwa pamwambapa, ndipo pachithunzi changa, sindiopa kuyika zoterezi kwa 100 kuti zibweretse mawonekedwe pankhope panga.

Voila! Tsopano ndili ndi chithunzi chimodzi chothandiza kwambiri:

“Kodi mukutentha mkati muno, kapena ndi ine ndekha?”

Tsopano popeza ndikusangalala ndi chithunzichi, ndiroleni ndibwerere mwachangu mayendedwe ochepetsa Phokoso:

Tsegulani chithunzi, ndipo mpweya (osati kwenikweni…)
Pitani ku Khalani gawo.
Open tsatanetsatane gawo.
Sinthani mtundu slider kuti muwone ngati china chilichonse kupatula kusasintha kwa 25 zimandipatsa zotsatira zabwino
Sinthani tsatanetsatane slider (pansi pa utoto) kuti muwone ngati ndingabweretse chilichonse chakumbali kutengera mtundu
Sinthani Luminance slider mpaka njerezo zivomerezedwe kapena mpaka chithunzicho chitayamba kusalala, ndikuchibweza kumbuyo
Sinthani tsatanetsatane slider (pansi pa Luminance) kuti muwone ngati ndingabweretse tsatanetsatane uliwonse wam'mbali kutengera kuwunika
Sinthani siyanitsani slider kuyesa kubweretsanso zina mwatsatanetsatane

Kunena zowona mtima, sindimakonda kugwiritsa ntchito zotchingira pansi ziwiri, ngati zingayambepo, Mtundu ndi Tsatanetsatane). Mfundo zosasinthika za Lightroom 2 zili pafupi kwambiri ndi zomwe ndingasankhe.

Kumbukirani, PALIBE chilinganizo cha matsenga, PALIBE cholondola, ndipo PALIBE cholakwika (chabwino, palibe chowopsa Luminance kuyang'ana kutsika kwa pulasitiki). Pali zokhazo zomwe zimakondweretsa kasitomala wanu.

Monga ojambula, timawona zithunzi zathu mosiyana ndi zomwe makasitomala athu amawona kuchokera pazowonera. Ngati mungatengeke mtima, kapena mphindi, ndipo mukulikhomera, nditha kubetcherana ngongole yanga yomwe kasitomala wanu sawona phokoso.

Ngati atero, tsopano mukudziwa momwe mungachepetsere!
