Kamera ya Digito Yowonetsera Usiku
Kujambula zithunzi usiku kwakhala kokongola nthawi zonse. Magetsi owala a mumzinda, njira zowunikira kuchokera m'magalimoto, thambo lakuda kwambiri, komanso ngakhale bata la m'mbali mwa msewu zonse zimatha kupanga zithunzi zolimbikitsa malingaliro. Komabe, vuto lalikulu la kujambula zithunzi usiku ndi kusowa kwa kuwala. Apa ndi pomwe Night Scene Mode pamakamera a digito imakhala chinthu chofunikira kwambiri, kuthandiza ogwiritsa ntchito kupeza zithunzi zowala, zakuthwa, komanso zachilengedwe popanda kufunikira kudziwa bwino makonda amanja.
Nkhaniyi ikufotokoza za mawonekedwe a usiku, momwe amagwirira ntchito, nthawi yogwiritsira ntchito, ndi malangizo othandiza kuti mupeze zotsatira zabwino kwambiri pazithunzi zanu za usiku.
Kodi Mawonekedwe a Usiku Ndi Chiyani?
Mawonekedwe a Usiku ndi njira yapadera yojambulira zithunzi pa makamera a digito (makamera am'thumba, makamera opanda galasi, ma DSLR, ndi makamera ena ochitapo kanthu) opangidwira nyengo yozizira, makamaka panja usiku. Njirayi nthawi zambiri imakhala ndi chizindikiro cha mwezi kapena nyenyezi.
Cholinga chachikulu ndikupangitsa kuti zithunzi za usiku ziwoneke bwino ndikuchepetsa phokoso (malo ovuta) pamene mukusunga tsatanetsatane m'malo amdima komanso owala monga magetsi amisewu, neon, kapena mawindo omanga.
Mosiyana ndi kujambula ndi flash, mawonekedwe a usiku nthawi zambiri amayesa kujambula kuwala kozungulira kuti asunge mawonekedwe a usiku. Flash nthawi zambiri imapangitsa anthu kuoneka ngati "athyathyathya" ndipo mawonekedwe akunja amawoneka akuda kwambiri; mawonekedwe a usiku, kumbali ina, amayesa kulinganiza mutu ndi maziko kuti chithunzicho chikhale chenicheni.
Momwe Mawonekedwe a Usiku Amagwirira Ntchito
Ngakhale kuti kamera iliyonse ili ndi ma algorithms ndi njira zosiyanasiyana, mfundo yogwirira ntchito ya mawonekedwe ausiku nthawi zambiri imakhala ndi zosintha izi:
1. Liwiro lotseka pang'onopang'ono (kuonekera nthawi yayitali)
Kamera imatsegula shutter nthawi yayitali kuti sensa ijambule kuwala kochulukirapo. Ichi ndichifukwa chake kujambula zithunzi usiku nthawi zambiri kumafuna dzanja lokhazikika kapena katatu, chifukwa ngakhale kusuntha pang'ono kungayambitse kusawoneka bwino.
2. ISO yawonjezeka mokwanira
ISO yapamwamba imapangitsa sensa kukhala yogwirizana kwambiri ndi kuwala, zomwe zimapangitsa kuti zithunzi zikhale zowala kwambiri. Komabe, ISO yapamwamba imayambitsanso phokoso. Chifukwa chake, makamera nthawi zambiri amaika ISO pamalire enaake kuti igwirizane bwino ndi kuwala ndi kumveka bwino kwa chithunzi.
3. Chitsekocho chimatsegulidwa mokulirapo (pa makamera omwe amachichirikiza)
Pa makamera omwe ali ndi njira yowongolera ma aperture, mawonekedwe a usiku nthawi zambiri amasankha aperture yayikulu (f-number yotsika) kuti kuwala kulowe. Chifukwa chake, kuya kwa malo kumatha kukhala kochepa, ngakhale kuti izi sizimachitika nthawi zonse mu kujambula zithunzi za malo.
4. Kukonza kuchepetsa phokoso
Makamera ambiri amagwiritsa ntchito njira yochepetsera phokoso kwambiri usiku ukagwira ntchito. Zotsatira zake zimakhala zithunzi zoyera, ngakhale kuti nthawi zina zinthu zazing'ono zimatha kufewetsedwa pang'ono.
5. Kuyika mafelemu ambiri (pa makamera ena amakono)
Kamera imatha kujambula zithunzi zambiri motsatizana kenako nkuziphatikiza kuti zichepetse phokoso ndikuwonjezera tsatanetsatane. Njirayi ndi yothandiza, koma imakhudzidwa kwambiri ndi zinthu zoyenda (odutsa, magalimoto, masamba omwe akuwomba mphepo), zomwe zingayambitse "zozizwitsa".
Ubwino wa Mawonekedwe a Usiku
Mawonekedwe a usiku ndi otchuka chifukwa ndi othandiza komanso oyenera zochitika zambiri. Ubwino wake ndi wina:
- Yosavuta kugwiritsa ntchito: ingosankhani mawonekedwe, onetsani kamera, ndikujambula chithunzi.
- Wonjezerani kuwala mumdima wopanda kuwala kokwanira popanda makonda ovuta pamanja.
- Amachepetsa chiopsezo cha zithunzi kukhala zakuda kwambiri (zosawonekera bwino), makamaka kwa oyamba kumene.
- Imasunga mlengalenga wa usiku chifukwa imadalira kuwala kozungulira.
- Yoyenera mawonekedwe a mzinda: magetsi a mzinda, nyumba, misewu, milatho, ndi malo owonetsera mzinda.
Zoyipa ndi Zolepheretsa
Ngakhale kuti ndi yothandiza, mawonekedwe a usiku si njira yothetsera mavuto onse:
- Zimakhala zosawoneka bwino kamera ikasunthidwa chifukwa shutter imachedwa.
- Zinthu zoyenda zimatha kusokonekera kapena kusokonekera, makamaka kamera ikadzaza.
- Zowala kwambiri "zimatuluka" mosavuta (zowonekera kwambiri) m'magalasi owala kwambiri.
- Mitundu nthawi zina imasintha chifukwa chakuti kuwala koyera kokha "kumasokonezeka" mukayang'anizana ndi magetsi osakanikirana a fluorescent, LED, ndi sodium.
- Tsatanetsatane ukhoza kuchepa ngati kuchepetsa phokoso kuli kolimba kwambiri.
Choncho, kumvetsetsa momwe kuwombera kumakhalira kofunikira kuti muthe kusintha momwe mumawombera.
Kodi Muyenera Kugwiritsa Ntchito Nthawi Yanji Usiku?
Njira iyi ndi yabwino kwambiri mukajambula:
- Mawonekedwe a mzinda usiku (magetsi a mzinda).
- Chizindikiro chodziwika bwino chokhala ndi magetsi okongoletsera.
- Misewu yokhala ndi magetsi a magalimoto imapanga mlengalenga wodabwitsa.
– Padoko kapena pagombe usiku ndi magetsi patali.
- Mawonekedwe a mudzi wausiku wokhala ndi kuwala kochepa koma kokhazikika.
Kumbali ina, ngati mukujambula zithunzi zothamanga usiku (monga masewera, makonsati othamanga, kapena ana othamanga), njira iyi singakhale yoyenera chifukwa liwiro la shutter limakhala lochepa. Muzochitika izi, ndi bwino kugwiritsa ntchito njira yamanja/yofunikira yokhala ndi liwiro la shutter lothamanga komanso ISO yokwera, kapena kugwiritsa ntchito lenzi yowala.
Malangizo Othandiza Okulitsa Zithunzi za Usiku
Kuti zithunzi zanu za usiku zikhale zakuthwa komanso zokongola, yesani malangizo awa:
1. Gwiritsani ntchito tripod kapena malo okhazikika
Tripod ndiye "chida chachikulu" chojambulira zithunzi usiku. Ngati mulibe, ikani kamera pakhoma, pa mpanda, patebulo, kapena gwiritsani ntchito thumba ngati chothandizira. Kukhazikika ndikofunikira kwambiri kuti chithunzicho chikhale chowala.
2. Yatsani chodziwerengera nthawi kapena chotchingira kutali
Kukanikiza batani la shutter kungayambitse kugwedezeka kwa kamera. Gwiritsani ntchito chodziwonera chokha cha masekondi awiri kapena chowongolera chakutali kuti mujambule zithunzi zakuthwa.
3. Samalani ndi magwero a kuwala kowala
Magetsi amsewu ndi zikwangwani zimatha kusintha malo owala kukhala oyera opanda kanthu. Yesani kusintha kapangidwe kake kapena kugwiritsa ntchito njira yochepetsera kufalikira kwa kuwala (monga -0,3 mpaka -1) ngati kamera yanu ilola.
4. Gwiritsani ntchito bwino mizere ndi kuwunikira
Usiku umakhala ndi kuwala kochuluka: phula lonyowa mvula ikagwa, magalasi omangira, pamwamba pa madzi, komanso matope ang'onoang'ono. Kuwalako kumawonjezera kukula ndi kukongola kwamphamvu.
5. Yesani njira zopepuka
Ngati mawonekedwe a usiku akuwonetsa kuwala kwakutali, mutha kujambula njira zowunikira magalimoto. Pezani malo otetezeka (odutsa msewu, otetezedwa) ndikuyesera kuyika mizere ya msewu ngati mizere yotsogola.
6. Khalani maso kwambiri
Usiku, autofocus ingakhale yovuta. Yang'anani pa zinthu zosiyana (magetsi, m'mphepete mwa nyumba), kapena gwiritsani ntchito focus yamanja ngati ilipo. Makamera ena amaperekanso zinthu zothandizira focus monga focus peak.
7. Samalani ndi kuyera bwino
Kusakaniza kwa kuwala kungapangitse zithunzi kukhala zachikasu kwambiri kapena zobiriwira. Ngati kamera yanu ili ndi zinthu zomwe zakonzedweratu (Tungsten/Incandescent) kapena Kelvin, mutha kuziyesa. Kujambula mu RAW kumathandizanso kuti kukonza mitundu kukhale kosavuta panthawi yosintha.
8. Musaope kujambula zithunzi
Kujambula zithunzi usiku nthawi zambiri kumafuna kuyesa. Tengani mafelemu angapo okhala ndi mitundu yosiyanasiyana komanso mawonekedwe osiyanasiyana. Chizolowezichi chimawonjezera mwayi wopeza zotsatira zabwino kwambiri.
Malo Owonera Usiku ndi Manja: Ndi Chiyani Chabwino Kwambiri?
Mawonekedwe a usiku ndi abwino kwambiri chifukwa ndi osavuta. Koma ngati mukufuna kulamulira kwathunthu—mwachitsanzo, kukhazikitsa liwiro la shutter la masekondi 10–30 pamayendedwe ataliatali a kuwala, kusunga ISO yotsika momwe mungathere kuti ikhale yapamwamba, kapena kutseka bwino kuti ikhale yofanana—ndiye kuti njira za Manual (M), Shutter Priority (S/Tv), kapena Aperture Priority (A/Av) nthawi zambiri zimakhala zosinthasintha.
Ojambula zithunzi ambiri amayamba ndi zochitika za usiku, kenako pang'onopang'ono amasinthira ku zoikamo zamanja atamvetsetsa ubale womwe ulipo pakati pa liwiro la shutter, ISO, ndi kutsegula. Mawonekedwe a usiku akhoza kukhala "mlatho" wothandiza kwambiri pophunzira.
Kutseka
Njira Yowonetsera Usiku ya Kamera Ya digito ndi njira yopangidwira kukuthandizani kujambula kukongola kwa usiku mwanjira yothandiza kwambiri. Mwa kusintha mawonekedwe, ISO, ndi kukonza zithunzi, njira iyi imalola ogwiritsa ntchito kupeza zithunzi zowala komanso zamlengalenga ngakhale mu kuwala kochepa. Ngakhale ili ndi zoletsa monga chiopsezo cha kufinya ndi kuwala kowonekera kwambiri, zotsatira zake zitha kukhala zokhutiritsa kwambiri—makamaka zikaphatikizidwa ndi njira zosavuta monga kugwiritsa ntchito tripod, kugwiritsa ntchito chowerengera nthawi, komanso kulabadira kapangidwe ka kuwala.
Pomaliza, kujambula zithunzi usiku sikuti ndi njira yokhayo yopezera zinthu, komanso kumverera. Nightscape mode imapereka njira yosavuta yopezera mawonekedwe okongola a mizinda, thambo lakuda lodekha, ndi nkhani zomwe zimangowonekera dzuwa litalowa. Ngati mukufuna, ndingakuthandizeni kupanga mtundu waukadaulo wa nkhaniyi (ndi makonda achitsanzo) kapena mtundu wopepuka wa mabulogu oyamba.
