Hoʻi i ke kiʻi kumu kiʻi: ka pilina ma waena o ISO, Shutter Speed ​​a me F-Stop

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 ʻelua 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 manaʻo ākea pehea ka hana pū ka triangle hōʻike. I kēia manawa e hele mākou i kekahi kikoʻī e pili ana i kēlā pilina.

ʻO ka mua o kahi kikoʻī hou aʻe ma kēlā me kēia o nā ʻāpana ʻekolu o ka hōʻike ʻana;

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.

Holo wikiwiki ʻo ka lōʻihi ka wehe o ka pale e ʻae ana i ka mālamalama e paʻi i ka mea ʻike. ʻO ka lohi o ka wikiwiki o ka shutter (1/15, 1/30) ʻo ka lōʻihi ka lōʻihi e hoʻokuʻi i ka mea ʻike. ʻO ka wikiwiki o ka wikiwiki o ka shutter (1/125, 1/250) ke kuʻikuʻi ke kukui pōkole i ka mea ʻike.

F-Kū ʻo ka wehe o ka puka. ʻO ka wehe i ke kukui e hele i ke ala i ka sensor. Mālama ʻo F-Stop i ka nui o ke kukui i hiki i ka mea ʻike a me ka hohonu o ke kahua (DOF). ʻO DOF kahi o ka nānā nui o kahi kiʻi. ʻO ka haʻahaʻa o ka helu F (1.4, 2.8) ʻo ka ākea o ka puka, ʻo ia ka DOF. ʻO ke kiʻekiʻe o ka helu F (8, 11) ka liʻiliʻi o ka puka, ʻoi aku ka nui o ka DOF.

I kēia manawa ua ʻike ʻoe i ka hana a kēlā me kēia mea i ka hana ʻana i kiʻi, e nānā i ke ala e hoʻoholo ai i kāu hoʻonohonoho ʻana.

Pehea e hoʻoholo ai i kāu hoʻonohonoho ʻana: Hoʻokahi ala o ka hana ʻana i kēia.

ʻO kaʻu makemake e hoʻoholo i kaʻu ISO ma mua. ʻOiai ʻo ISO ka ʻike o ke kiʻina i ka mālamalama, i nā hiʻohiʻona mālamalama mālamalama, e like me waho i ka mālamalama o ka lā, ma ke kahakai a i ʻole pāka e koho wau i kahi ISO haʻahaʻa, 100. Inā he lā keu paha 200 paha. ʻAʻohe kumu no ka ma kahi kiʻekiʻe ISO i nā hanana mālamalama o ke ao. Aia paha he ʻokoʻa. Ma ke ʻano he kānāwai maʻamau he 100 a 200 paha e hana maikaʻi ma waho o ka hale i ka hapanui o nā kūlana. I nā hoʻonohonoho mālamalama haʻahaʻa, i ke ahiahi, e hoʻokokoke ana i ke ahiahi, koho wau i 400, 800 paha, e hilinaʻi ana i ka nui o nā kukui i loaʻa. Ma loko wau e koho 400 me ka uila 800 paha inā makemake wau e ʻike hou i nā kukui o ka lumi, 1600 paha, ʻoi aku ke kiʻekiʻe inā wau e hana me nā kukui i loaʻa, e like me ka hale pule ʻaʻole ʻae i ka paʻi kiʻi.

Ke koho wau i kaʻu ISO, hoʻoholo wau i ka hohonu o ke kahua (DOF) makemake au. Makemake au i kahi DOF pāpaʻu, (F-2.8, 4.0) a i ʻole DOF hohonu (F-11 a ʻoi aku paha). Ke hoʻoholo nei wau i kēlā me kēia mea aʻu e pono ai e hoʻonohonoho i kaʻu Shutter Speed ​​e pili ana i kēlā mau hoʻonohonoho ʻelua, kaʻu F-Stop a me ISO. Ke hoʻonohonoho wau i kaʻu Shutter Speed, e hana wau i kekahi mau kiʻi hoʻāʻo e ʻike pono i kaʻu hōʻike ʻana, inā ʻaʻole, e hana wau i nā hoʻoponopono liʻiliʻi e loaʻa ai kahi hōʻike maikaʻi.

Lana koʻu manaʻo e hāʻawi hou kēia iā ʻoe i ka hohonu o ka nānā ʻana i kā mākou triangle hōʻike. E hele a hoʻomaʻamaʻa. E loaʻa i kahi lima maikaʻi e pili ana i ka hana o ka triangle hōʻike. Hana i kēlā a ke hele nei ʻoe i ka hana ʻana i nā kiʻi maikaʻi ʻole e koi aku i ka hoʻoponopono ʻana, kahi hoʻoponopono hoʻokele wale nō. Ke hoʻomau nei kā mākou ʻatikala, e kikoʻī mākou i ka huinakolu hōʻike.

Inā he nīnau kāu, e ʻoluʻolu e kāhea iaʻu [pale ʻia ka leka uila]. Hele kēia leka uila i kaʻu kelepona no laila hiki iaʻu ke pane wikiwiki. E hauʻoli wau e kōkua i kēlā me kēia ala e hiki ai iaʻu.
