Hoʻi i ke kiʻi kumu kiʻi: ma ka hohonu e nānā iā ISO

Hoʻi i ke kiʻi kumu kiʻi: kahi nānā hohonu ma ISO

I nā mahina e hiki mai ana e kākau ana ʻo John J. Pacetti, CPP, AFP, i kahi papa o nā haʻawina kiʻi kumu.  E ʻike iā lākou āpau e ʻimi wale “E hoʻi i nā kumuhana”Ma kā mākou blog. ʻO kēia ka ʻatikala ʻekolu o kēia moʻo. He malihini pinepine ʻo John i ka Pūʻulu Kaiāulu MCP Facebook. E hōʻoia e hui pū - manuahi a nui ka ʻike.

I kā mākou ʻatikala hope loa ua hāʻawi wau iā ʻoe i kahi nānā i ka triangle hōʻike. I kēia manawa e hele hohonu mākou me ISO.

ISO ʻo ia ka manaʻo o ka mea ʻike. Hōʻiliʻili ka mea ʻike i ke kukui. ʻO ke kukui uila ka mea e hana ai i kāu kiʻi. ʻO ka lalo o ka helu ISO ka nui o ka mālamalama e pono ai e hana i kahi kiʻi, nā hiʻohiʻona mālamalama. ʻO ke kiʻekiʻe o ka helu ISO ka liʻiliʻi o ka mālamalama e pono ai e hana i kahi kiʻi, nā hiʻohiʻona ʻeleʻele.

Ke ʻike nei i ka ISO i loko, koʻu manaʻo, ka hapa nui i maopopo ʻole i nā ʻekolu o ka ka huinakolu hōʻike. Inā pilikia ʻoe i kēia, ʻaʻole wale ʻoe. Hoʻi i ka lā kiʻi ʻoniʻoni, koho ka hapa nui o ka poʻe i ka wikiwiki he 100 a 400 paha. Ua haʻi ʻia ʻoe e hoʻohana i ka 100 no waho a me 400 i loko o ka hale. He ʻoiaʻiʻo nō naʻe kēia. ʻO nā kāmela uila o kēia lā, akā e hāʻawi iā mākou i kahi pae ISO ʻoi aku ka nui ma mua o ka kiʻi ʻoniʻoni. E hāʻawi ka hapa nui o ka mīkini uila iā ʻoe i kahi pae o 100 a 3200 a ʻoi aku. Hele kekahi o nā kāmera hou i 102400.

ʻO ka ISO ka mea aʻu e hoʻonohonoho maʻamau ai i ka hoʻoholo ʻana i kaʻu hoʻonohonoho ʻana. Eia kekahi mau hanana.

• ʻOiai wau e hana nei i waho, kahi laʻana, kahi pāka me ka pāʻina male a i ʻole ke kaʻina kiʻi, kahi hui a i ʻole kahi ʻohana, ʻaʻole wau e pono i kahi ISO kiʻekiʻe. E hoʻohana wau i 100. ʻO ka manawa wale wau e koho ai iā 200 inā ʻoi aku ia ma mua o ka hoʻolei ʻana a kokoke paha i ke ahiahi kahi e pono ai iaʻu i kahi mālamalama hou aʻe e kiʻi i kaʻu hōʻike maikaʻi.
• I kēia manawa, inā wau e hana nei i kahi hanana māmā haʻahaʻa, no ka laʻana, he hale pule i ʻae ʻole i ka paʻi kiʻi paʻi, e koho wau i ISO o 800, 1600, hiki i 2500. Pono wau i ka ʻike o ke kiʻiona e ʻoi aʻe. ʻO ka ʻike kiʻekiʻe o ke kiʻiona e ʻae iaʻu e mālama i kaʻu F-Stop a me SS kahi aʻu e makemake ai iā lākou e hana i kaʻu hōʻike maikaʻi i kēlā kūlana kukui.
• E ʻōlelo wau makemake wau e hana me ka mālamalama o ka puka aniani i loaʻa. Hoʻolahalaha ka mālamalama pukaaniani (no ka hapa nui) kukui lā. E hele wau me 400 paha 800 inā ʻaʻole lawa ka mālamalama e like me ka lā ʻōpua. Eia hou, ke hoʻonohonoho nei i kaʻu F-Stop a me SS ke loaʻa iaʻu kaʻu ISO.

Hoʻohui hou: E hoʻohana i kahi ISO haʻahaʻa i nā wahi mālamalama mālamalama (100). I nā kūlana kukui haʻahaʻa, e hoʻohana i ka ISO kiʻekiʻe (400, 800, 1600). Ke hoʻoholo ʻoe i kāu ISO, hiki iā ʻoe ke hoʻonohonoho i kāu SS a me F-Stop.

Lana koʻu manaʻo e hāʻawi kēia iā ʻoe i kahi manaʻo maikaʻi e pili ana i ka hana a ISO a pehea e hoʻohana ai iā ISO i kou pono. ʻO ka hoʻonaʻauao ke kī. I ka manawa e loaʻa iā ʻoe kēlā aʻo ʻana, ʻaʻole kaohi i kahi ʻoihana kiʻi maikaʻi. ʻAʻole pau ke aʻo ʻana, ʻaʻohe kanaka i ʻike i nā mea āpau.

ʻO ka manawa aʻe e nānā mākou iā F-Stop.
