No ke aha ka mīkini paʻi kiʻi?

Ua ʻike mua ʻoe ʻo ke kiʻi he kiʻi o ka mālamalama a ʻike ʻoe ua ʻike kou mau maka i ka mālamalama a ʻo ia ke kumu i hana ai mākou i nā mea ʻike uila e ana i ka māhele o ka mālamalama e komo i kā mākou pahupaʻi. Maopopo anei iā ʻoe ke ʻano o ka mīkini paʻi kiʻi?

ʻO ka photometer kahi mea e hōʻoiaʻiʻo ai iā ʻoe i ke ana o ka mālamalama kūikawā a lawa hoʻi i hoʻopaʻa ʻia kāu kiʻi me ka ʻike kupaianaha, ʻoi, wehewehe, ʻokoʻa, saturation, mahana, leo, i ʻole ʻoe e hana i kekahi mea. . hana hope. .

Makemake ʻoe e ʻike i ke ʻano o ka photometer?

No ke aha ke kiʻi mika?

Hoʻohana ʻia ka mika māmā no ke ana ʻana i ka mālamalama ambient. Me ia e ana ʻoe i ka ikaika a me ka māmā. Kapa ʻia kēia ana he photometry.

Hana ʻia ka Photometry e ka maka o ke kanaka a hiki i ka hana ʻana i nā mea kani. ʻO ka mīkini paʻi kiʻi he mea hana, kahi mea hoʻohana, hoʻohana ʻia e nā mea paʻi kiʻi.

Aia nā kiʻi kiʻi i hana ʻia no nā manawa like ʻole. Ma ke kūlana hoʻohana no ke kiʻi kiʻi, hiki iā lākou ke kūʻokoʻa a hoʻohui ʻia paha i loko o ke kāmela.

Hiki i nā mika māmā ke ana a hoʻohālikelike i kekahi mau kumu kukui ʻokoʻa ke ʻike ʻia nā hiʻohiʻona kikoʻī o kekahi kumu a maʻamau a ʻaʻole kekahi. Hāʻawi ka photometer i ka hoʻohālikelike pololei o ka mālamalama mai nā kumu like ʻole.

Genera of Photometers

ʻElima ʻano mika māmā i hoʻohana mua ʻia i ke kiʻi, e like me ke aʻo ʻana i kēia manawa.

kiʻi kiʻi kala

ʻO nā mika māmā kala e ana i ka ratio o ke kukui e hāʻule ana ma luna o kahi mea me ka ikaika o ke kala i hoʻopuka ʻia mai ia mea. Hoʻohana ʻia kēia mau mika māmā no ke kaulike ʻana i ka saturation kala a ʻoi aku ka maikaʻi i ka wā e pili ana i ke kiʻi.

nā mīkini paʻi kiʻi lima

Hoʻohana ʻia kēia mau mea no ka nānā ʻana i nā heluhelu māmā ma kekahi mau wahi o ke kiʻi.

nā mīkini paʻi kiʻi i hoʻohui ʻia

He mau photometers i hoʻohui ʻia i loko o ka ʻaukā. Ua ulu ka hana i ka manawa i ʻike ʻia ai ka pili o kahi photometer i ke kiʻi ʻana i nā kiʻi. ʻO ka hapa nui, i ka manawa e hele ai ka mea kuhikuhi i -0 - loaʻa iā mākou kahi lokahi i makemake ʻia.

nā kiʻi kiʻi kiko

No ka lawe ʻia ʻana o kēia mau heluhelu māmā mai nā wahi like ʻole o ke kumuhana i paʻi ʻia, hoʻohana ka mea paʻi kiʻi i kēia mau heluhelu no ka hoʻomaopopo ʻana i ke ʻano o ka hoʻololi ʻana i ka ʻike ʻana o ke kāmela no nā wahi i aʻo ʻia.

nā kiʻi kiʻi māmā i hana ʻia

ʻO kēia mau mika māmā e ana i ka mālamalama i hana ʻia a me ka hapa o ka mālamalama ma ke kumuhana. ʻO ia ka pololei loa o nā kiʻi kiʻi ʻelima.

No ka ʻoihana wai, aia nā ʻano kiʻi kiʻi ʻē aʻe, e like me:

Nā kiʻi kiʻi kiʻi i hoʻohana ʻia i ka mahiʻai iʻa, ʻo ia hoʻi, ka mahi ʻai iʻa. Ke ʻōlelo nei lākou aia ka nui o ka māmā i loko o ka wai e ola ai ka iʻa.

Nā kiʻi kiʻi e hoʻoholo i ka pae o oxygen i ka wai me ka pH o ka wai. Hoʻomaopopo pū ka photometer inā loaʻa nā phosphates a i ʻole nā ​​​​minela ʻē aʻe.

Hoʻohana ʻia nā kiʻi kiʻi kiʻi i loko o nā loko ʻauʻau a me nā lumi ʻauʻau e nānā i ka hapa o ka mālamalama i hiki i nā mea ke komo.

Nā kiʻi kiʻi e hoʻokumu i ka koi o ka oxygen i nā kino wai kūpono no nā kumu like ʻole.

He aha ka hana o ka mīkini paʻi kiʻi?

ʻO kēlā me kēia hana ʻana i nā kiʻi, mai ke kiʻi paʻi kiʻi, pono e lawa ka hoʻokomo ʻana o ka mālamalama no ka hoʻopaʻa ʻana, inā paha ia i hoʻopaʻa ʻia ma ke kiʻiʻoniʻoni a i ʻole ke kāleka hoʻomanaʻo.

Hiki i nā maka kanaka ke ʻike a paʻa i ka ikaika o ka mālamalama, akā ʻaʻole hiki ke ana i ka wikiwiki o kona ʻike ʻia ʻana. No kēia, loaʻa iā mākou ka photometer nona ka hana photometry.

Nānā nā kiʻi kiʻi kiʻi i ka pili ʻana o ka mālamalama me nā mea hoʻohālike. ʻO ka pūʻulu o nā photometers e ʻae i ka hoʻohana ʻana i ka photometry ma nā ʻano kula like ʻole.

ʻO nā kiʻi kiʻi kiʻi ʻē aʻe e pana i ke kukui keʻokeʻo ma nā ʻili e ana i ka nui o ka mālamalama e ʻike ʻia i ka mea kani.

Ma ka astronomy, hoʻohana ʻia ka photometry ma ke kau ʻana i nā kānana e kaupalena i kekahi mau nalu nalu a ʻae e ana i nā lōʻihi nalu makemake ʻē aʻe.

He kuleana koʻikoʻi ka Photometers i ka ʻae ʻana i ka poʻe ʻepekema e nānā a hopu i nā kiʻi o nā kino lani.

HE LA'ANA:

ʻO kahi laʻana o ke ʻano o ka hana ʻana o ka mīkini paʻi kiʻi, ʻo ia ke kau ʻana i kahi ʻāpana pepa me kahi ʻaila ʻaila ma waenakonu e hoʻoheheʻe ʻia kēlā ʻāpana o ka pepa.

HE HANA

No ke kaʻina hana hoʻopau aka, holo ka mita ma ka hoʻolei ʻana i nā aka, e like me ka manaʻo o ka hoʻomohala ʻana. Inā hoʻolei ke kumu kukui i ke aka o kahi mea opaque ma kahi hōʻike, hoʻokomo i kahi kumu lua mai kahi mamao e wehe i ke aka.

Hoʻohana i nā kiʻi kiʻi

Loaʻa iā lākou ka hiki ke ana i ka mālamalama

Hoʻonohonoho kēia hana i ka ʻike māmā o ka maka kanaka. Hoʻohana ʻia ka maka kanaka ma ʻaneʻi ʻoiai ʻo ia ka mea hana mua e ana i ka ikaika a hiki ke hoʻokaʻawale physiologically i kahi ākea ākea.

ʻO ka fluorescence

Hiki i nā kiʻi kiʻi kiʻi ke hoʻokaʻawale i waena o nā hiʻohiʻona māmā, nā mea fluorescent, a me nā mea ʻaʻole. Hoʻopili nā mea fluorescent i ka mālamalama me nā pāhawewe ʻē aʻe a hōʻike i ke kukui i komo.

Hoʻopau

Hiki i nā kiʻi kiʻi ke aʻo i ka ikaika o ka nalu o ka mālamalama mai kahi mea e hoʻomoʻa i ka ikehu me ke ʻano o ka mea.

ʻōuli māmā

Hiki i nā kiʻi kiʻi kiʻi ke aʻo i ke kiʻekiʻe o ke kukui ʻana i kahi mea, e like me ke kūlana o kahi speculum; a i ʻole ke komo ʻia ke kukui e ka mea. Pili kēia i ke ʻano a me ke ʻano o ka mea.

hoʻopuehu māmā

Kōkua nā Photometers e ʻike i ke kukui keʻokeʻo i hoʻokuʻu ʻia, wāwahi ʻia, i kēia manawa e ʻike pono i ka pae i hana ʻia, a me kona ikaika. ʻO ke ānuenue kahi laʻana o ka lūlū māmā.

Pākuʻi

Ua like nā mea Phosphorescent me nā mea fluorescent, akā ʻike ʻia ka ʻokoʻa i ka nui o ka mālamalama i hoʻopuka ʻia. ʻAlohilohi kekahi mau mea i ka pōʻeleʻele no ka mea e hoʻomoʻa lākou i ka mālamalama a, no ka mea e hoʻomālamalama mālie lākou i ka mālamalama, e hoʻomau i ka hoʻopuka ʻana i ka mālamalama ma hope o ka lawe ʻana.

Luminescence

ʻO ka luminescence ka lawe ʻana i ka mālamalama, akā ʻaʻole ma muli o ka wela. Ma muli paha o ka hopena kemika a i ʻole ka ikehu uila. ʻO ka hapa nui o nā mea hana mokulele no ka hoʻokele ʻana e hoʻohana i nā mea luminescent, a ʻo ia ka mea e ʻike ʻia mai kahi mamao. Kōkua nā kiʻi paʻi kiʻi e hoʻokaʻawale i nā mea i luminescent a ʻaʻole.

Luminescence

Pehea e hana ai i ka photometry o ka lani?

Inā makemake ʻoe e hoʻopaʻa i nā hōkū, e ʻimi i kahi mamao mai ke kikowaena kūlanakauhale, e lawe i nā pilikia koʻikoʻi insecurity, e hoʻohana i kahi tripod.

Inā makemake ʻoe i nā kiʻi kiʻi o nā hōkū, me ka ʻole o nā kīnā a i ʻole nā ​​ʻōpala, e hoʻohana i ka puka kiʻekiʻe i hāʻawi ʻia e kāu lens a hoʻohana i ka ISO kiʻekiʻe loa i loaʻa iā ʻoe ma ke kāmela. ʻOi aku ka liʻiliʻi o ka puka a ʻoi aku ka lōʻihi o ka manawa hōʻike (30 s), ʻoi aku ka lōʻihi o nā hōkū i kāu kiʻi.

Inā makemake ʻoe e hopu i ka neʻe ʻana o nā hōkū i hiki iā ʻoe ke ʻike i nā ʻōkuhi o ka mālamalama i ka lani ʻeleʻele, e hoʻohana i ka manawa lōʻihi o ka hōʻike ʻana, ua kapa ʻia kēia hopena i ka hint hōkū a makemake nā mea paʻi kiʻi e hoʻohana. No ka loaʻa ʻana o ka hopena āu e makemake ai, e hana i kahi helu maʻalahi: 500+ no ka lōʻihi o ke kiko o ka lens, no ka laʻana, inā wau e hoʻohana i kahi lens 10mm, hiki iaʻu ke hoʻohana a hiki i 50 kekona me ka ʻole o ka hoʻopaʻa inoa ʻana i nā hōʻailona o nā hōkū.

E hoʻāʻo me kēia mau hoʻololi a ʻike i nā hopena!

10mm + iso 1000 + f3/5 + 30s

10mm + iso 1000 + f3/5 + 30s

24mm + iso 1600 + f1/8 + 15s

Inā makemake ʻoe e paʻi kiʻi i ke ao, e noʻonoʻo ʻoe i ka lani he kumu kukui e pono ke ana ʻia a nānā ʻia i ʻole e pahū ka ikaika o ka mālamalama a waiho i nā mea āpau keʻokeʻo - no kēia, ma hope o ka hāʻawi ʻana i ke keʻokeʻo ma ka photometer, hoʻemi i kahi kuhikuhi i ka wehe.

ka hopena

Mai poina i kahi kiʻi kupanaha! E aʻo i ka hoʻohana ʻana i ka mika māmā, i ka lima lima a i ʻole i loko o kāu pahupaʻikiʻi. E hoʻohana i nā ʻenehana manuahi e hana i nā kiʻi hoihoi a me nā moʻolelo.

Me nā ʻano ʻano like ʻole o nā photometric manuahi a me nā hāmeʻa ma ka mākeke, hiki iā ʻoe ke loaʻa i nā kumukūʻai nui a hiki i nā kumukūʻai kūʻai hou aku, pono e nānā a ʻike i kēlā me kēia o nā manawa e ola a lawe i kāu kiʻi kukui. .

E waiho i kahi manaʻo a haʻi mai iā mākou e pili ana i kāu ʻike me ka photometry!
