Kodi Mungasankhe Bwanji Lens Yoyenera Yokhala ndi Ngodya Yotakata Mukamajambula Nyenyezi?

Magalasi a ngodya zazikuluimapereka malo owoneka bwino, zomwe zimakupatsani mwayi wojambula thambo lalikulu usiku komanso zinthu zovuta za Milky Way pojambula nyenyezi. Ndiye, mumasankha bwanji lenzi yolondola ya ngodya yayikulu pojambula thambo lodzaza ndi nyenyezi?

Kusankha lenzi yoyenera yokhala ndi ngodya yayikulu kumafuna kuganizira zinthu zingapo. Tiyeni tiwone zinthu zazikulu zomwe zimakhudza:

1.Kusankha kutalika kwa focal

Kutalika kwa 14-24mm ndiko kutalika kwabwino kwambiri kwa magalasi ozungulira kuti ajambule thambo lodzaza ndi nyenyezi. Kumatha kujambula Milky Way yonse pamene ikuonetsetsa kuti chithunzi chili bwino m'mphepete mwake, zomwe zimapangitsa kuti chikhale choyenera kujambula zithunzi za Milky Way ndi zochitika zomwe zimaphatikiza minda ya nyenyezi ndi malo okongola.

Mwachitsanzo, kugwiritsa ntchito kutalika kwa 14mm kumakupatsani mwayi wojambula thambo lalikulu ndikujambula mawonekedwe onse a Milky Way, pomwe kugwiritsa ntchito kutalika kwa 24mm kumakupatsani mwayi wojambula zambiri za malowo.

2.Kusankha malo otseguka

Mukajambula thambo lodzaza ndi nyenyezi, ndi bwino kusankha lenzi yokhala ndi ngodya yayikulu yokhala ndi chitseko chachikulu kwambiri, chifukwa chitseko chachikulu chili ndi ubwino waukulu m'malo opanda kuwala kokwanira. Chitseko chachikulu chimatsimikizira kuti kuwala kumalowa mokwanira, zomwe zimathandiza kupewa njira za nyenyezi pomwe nthawi yomweyo zimathandizira kuti ISO isawonekere bwino—potero zimachepetsa phokoso ndikutulutsa zithunzi momveka bwino komanso zoyera.

Mukajambula thambo lodzaza ndi nyenyezi, ndibwino kusankha malo otseguka a F2.8 kapena kupitirira apo. F2.8 ndi malo oyambira omwe ndi oyenera pazithunzi zambiri, pomwe F1.4-1.8 ndi yabwino kwambiri ndipo ndi yoyenera malo opanda kuwala kwambiri.

Mukajambula thambo lodzala ndi nyenyezi ndi mandala akuluakulu, muyenera kuganizira za kutsegula kwa denga.

3.Kuwongolera khalidwe la chithunzi

Magalasi a ngodya zazikuluAmakhala ndi vuto la kusinthasintha kwa chromatic ndi mavuto a kusokonekera kwa migolo; lenzi yabwino kwambiri iyenera kukhala yokhoza kuwongolera kusinthasintha kwa chromatic ndi kusokonekera bwino. Pojambula thambo lodzaza ndi nyenyezi, ngati lenziyo siilamulira kusinthasintha kwa chromatic bwino, mipiringidzo yofiirira ingawonekere mozungulira nyenyezi, pomwe kusokonezeka kudzapangitsa kuti chithunzicho chisokonezeke, zomwe zimakhudza zotsatira zake zonse.

Chifukwa chake, ndikofunikira kusankha lenzi yomwe imasonyeza ulamuliro wapamwamba pa kusintha kwa chromatic ndi kupotoka. Kuphatikiza apo, ndikofunikira kusankha lenzi yowoneka bwino kwambiri kuti muwonetsetse kuti nyenyezi zikuwoneka bwino komanso zakuthwa, kupewa kusawoneka bwino.

4.Kuyang'ana pamanja molondola

Mu malo amdima, ntchito ya kamera yoyang'ana pa autofocus nthawi zambiri imakhala yosagwira ntchito, zomwe zimapangitsa kuti pakhale kusintha kwa focus pamanja—makamaka, kuyika mphete yoyang'ana pa infinity (∞). Komabe, ndikofunikira kudziwa kuti infinity mark pa sikelo ya mtunda wa lens nthawi zambiri imakhala ndi zolakwika pang'ono ndipo siingadaliridwe yokha.

Chifukwa chake, ndikofunikira kusankha lenzi yokhala ndi damping yapakati komanso kuyenda mtunda wautali kuti muzitha kusintha bwino mawonekedwe ndikuwonetsetsa kuti nyenyezizo ndi zowala komanso zowala.

Kujambula thambo lodzaza ndi nyenyezi ndi lenzi yozungulira nthawi zambiri kumafuna kuyang'ana pamanja

5.Kulemera ndi kuchuluka

Ngati mukufuna kunyamulamandalaPanja kwa nthawi yayitali, muyenera kuganizira kulemera ndi kukula kwa lenziyo. Mwachitsanzo, mukanyamula zida zochitira zinthu zakunja zomwe zimafuna nthawi yayitali, monga kukwera mapiri kapena kukwera mapiri, ndikofunikira kusankha lenzi yokhala ndi kapangidwe kopepuka kuti muzitha kuyenda mopepuka ndikuchepetsa katundu wanu.

Kuphatikiza apo, ndikofunikira kusankha lenzi yoyenera kutengera bajeti yanu. Ngati muli ndi bajeti yayikulu, mungasankhe lenzi yapamwamba kwambiri; komabe, ngati bajeti yanu ndi yochepa, nthawi zambiri ndibwino kusankha lenzi yomwe ikugwirizana ndi zofunikira zanu zojambulira.

Maganizo Omaliza:

Ngati mukufuna kugula mitundu yosiyanasiyana ya magalasi owunikira, owunikira, owunikira ma drone, nyumba yanzeru, kapena ntchito ina iliyonse, tili ndi zomwe mukufuna. Lumikizanani nafe lero kuti mudziwe zambiri za magalasi athu ndi zowonjezera zina.
