A waje, da hasken rana, kuna amfani da walƙiya azaman haske mai cikawa ba babban haske ba ko key kamar kuna yi a cikin gida.

 

Bayyanar da kai ya kamata koyaushe ya dogara ne da hasken fitilar maɓallinku (a wannan yanayin rana), don haka kuna buƙatar fara saita fallasa shi. Hakanan, kuna buƙatar lura da saurin “daidaitawa” na kyamara. Ga yawancin kyamarorin Canon yana da 1/200 ko 1/250. Don Nikon zai iya zuwa sama da 1/500.  Idan baku san menene saurin aikin kamarar ku ba, kuna buƙatar duba sama X-aiki tare a cikin littafin mai mallakin kyamararka, ko kan layi.

 

Saurin aiki tare shine saurin gudu mafi sauri wanda zaka iya amfani dashi tare da bugun jini na yau da kullun.  Akwai wani yanayin yanayin walƙiya wanda zai ba ku damar zuwa sama aiki tare da aka bayyana a ƙasa.

 

Tunda saurin rufewar abu ne mai iyakancewa ga fallasa, kana bukatar yin tunani a cikin yanayin fifikon Shutter Speed ​​(duk da cewa zaka harbi tare da kyamarar ka a yanayin shigarwar Manual). Don kiyaye saurin ƙofa a, ko synasan aiki tare a cikin haske mai haske, yi amfani da mafi ƙarancin tsarin saiti na kamara yana da - galibi 100 ko 200. Wannan zai ba ku damar bayyanawa tare da babbar buɗewar da zai yiwu. Idan ana buƙata zaku iya rage saurin rufewa, wanda zai buƙaci ƙaramar buɗewa, don samun zurfin filin.  Amma a yanayin walƙiya na yau da kullun, kar a taɓa “daidaita aiki” ta kamarar.

 

Matakan ku zuwa yanzu sune:

 

1. Zabi mafi karancin saitin ISO

2. Sanya saurin rufewa zuwa saurin aiki tare na kyamara (1/200 zuwa 1/500 ya danganta da aikin kyamara da samfura)

3. Daidaita budewa don haske (yi amfani da ma'aunin kyamara na al'ada)

4. Idan ana buƙatar tharin Zurfin, rage saurin bugun sannan sake saita ap

 

Sannan kawai kuna kunna fitilar don ƙara cika. A cikin yanayin TTL kuna daidaita fitowar walƙiya don ɗanɗana ta amfani da walƙiyar EV ta sarrafawa - ƙari don ƙari kuma a rage kaɗan. Lokacin da kuke da wadataccen haske a wurin, lokaci ne mai kyau don amfani da saitin TTL-BL na Nikon (BL yana tsaye ne da Hasken Daidaitawa). Yana ƙoƙari ya haɗu da cikawa tare da hasken da ke akwai, sabili da haka, yana saukar da fitowar haske.  Tare da Canon kyamarori kawai kuna buƙatar ƙananan EV.

 

Da zarar kun sami wannan ƙasa, yanzu zaku iya sarrafa bayanan biyu daban. Mitar da aka gina ta ba ka bayanan baya kuma saitin walƙiya yana ba ka damar bayyanawa ta gaba. Don haka, gwada duhun bango ta hanyar ɗan bayyanawa, da kuma daidaita hasken da ke gaba (saukar da filashi ko FEC) sama da ƙasa shima.

 

Tare da aiki, zaku sami cikakken iko game da yawan cikawar da kuke so haɗe da haske ko duhun da kuke son bango.

 

A cikin ƙananan haske na waje, kawai kuna kunna walƙiya kuma bari walƙiya a cikin yanayin TTL ta riƙe ɗaukar muku.  Ya sake zama mabuɗin haske, kuma kuna amfani da ɗan jinkiri don ɗaukar ɗan haske daidai da yadda kuka koya ta amfani da walƙiya a cikin gida.

 

A cikin haske mai haske lokacin da kake gaske buƙatar zurfin zurfin Yanki kuma suna amfani da walƙiya don "cika", dole ne kuyi amfani da yanayin daidaitawa na Babban Sauri.  Nikon da Olympus suna kiran shi yanayin daidaitawa na Focal Plane (FP), saboda yana ba da damar yin amfani da ƙofar "mai da hankali game da jirgin sama" wanda aka samo a cikin kyamarorin nau'in Lens Reflex (SLR).  Idan kana da kyamarar dijital ta zamani, kamar Canon XSi ko XTi, ko Nikon D90, galibi ana kiranta DSLR don Digital Single Lens Reflex.
