1.He aha ka lens kihi ākea?

A leki kihi ākeahe lens me ka lōʻihi pōkole. ʻO kāna mau hiʻohiʻona nui ka ʻike ākea ākea a me ka hopena kuanaʻike.

Hoʻohana nui ʻia nā lens ākea ākea i ke kiʻi kiʻi ʻāina, kiʻi hale kiʻi, kiʻi i loko, a i ka wā e pana ai e pono ke kiʻi i nā hiʻohiʻona ākea.

2.He aha ka hoʻohana ʻana i ka lens ākea ākea?

Loaʻa nā lens ākea ākea i kēia mau hoʻohana:

Hoʻoikaika i ka hopena kokoke

No ka mea ʻoi aku ka hohonu o ka lens ākea ākea, hiki iā ia ke hoʻokō i kahi hopena pili kokoke. Hiki i ka hoʻohana ʻana i kahi lens ākea ākea e pana i nā mea mua e like me nā mea mamao, hoʻonui i nā mea mua, a hoʻopuka i kahi hohonu hohonu o ka hopena kahua, e hoʻohui i ke ʻano o ka waiho ʻana a me ka ʻekolu-dimensionality i ke kiʻi holoʻokoʻa.

ʻO ka lens ākea ākea

Hoʻonui i ka hopena kuanaʻike

I ka hoʻohana ʻana i kahileki kihi ākea, e loaʻa kahi hopena kokoke-nui a lōʻihi-liʻiliʻi, kahi i ʻike nui ʻia ʻo ka "fisheye effect". Hiki i kēia hopena kuanaʻike ke hoʻohālikelike i ka mea i kiʻi ʻia i kahi kokoke i ka mea nānā, e hāʻawi ana i ka poʻe i kahi manaʻo ikaika o ka lewa a me ka ʻekolu-dimensionality. No laila, hoʻohana pinepine ʻia nā lens ākea ākea i nā kiʻi kiʻi kiʻi e hōʻike i ka hanohano a me ka wikiwiki o ka hale.

Hopu i nā hiʻohiʻona nui

Hiki i ka lens ākea ākea ke hōʻike i kahi kihi ākea ākea, hiki i nā mea paʻi kiʻi ke kiʻi i nā hiʻohiʻona hou aʻe i nā kiʻi, e like me nā mauna mamao, nā kai, nā panorama kūlanakauhale, a me nā mea ʻē aʻe. nā hiʻohiʻona pono e hōʻike i ke ʻano o ka ākea ākea.

Nā noi kiʻi kūikawā

Hiki ke hoʻohana ʻia nā lens ākea ākea no nā kiʻi kūikawā, e like me ke kiʻi ʻana i nā kiʻi kokoke a i ʻole nā ​​palapala moʻokalaleo, hiki ke hana i nā hiʻohiʻona ʻike maoli.

3.ʻO ka ʻokoʻa ma waena o ka lens ākea ākea a memaʻamaulekiō

ʻO nā lens ākea ākea a me nā lens maʻamau nā ʻano lens maʻamau i ke kiʻi. ʻOkoʻa lākou ma nā ʻano like ʻole:

Nā kiʻi i paʻi ʻia me ka lens ākea ākea vs

Hiki ke ʻike ʻia

A leki kihi ākeaʻoi aku ka nui o ka ʻike a hiki ke hopu i nā mea puni a me nā kikoʻī. He mea pono kēia no ke kiʻi ʻana i nā ʻāina, nā wahi i loko, a i ʻole nā ​​hiʻohiʻona kahi e pono ai ke koʻikoʻi i ke kua.

I ka hoʻohālikelikeʻana, heʻuʻuku keʻano o ka nānāʻana i nā lens maʻamau aʻoi aku ka maikaʻi no ke kiʻiʻana i nā kiko'ī kūloko, e like me nā kiʻi kiʻi a iʻole nā ​​hiʻohiʻona e pono e hoʻonui i ke kumuhana.

Kiʻi kiʻiʻoniʻoni

Hoʻomaka ka lens ākea ākea mai kahi kihi ākea ma mua o ka lens maʻamau. Hiki i kahi lens ākea ākea ke hopu i kahi ākea ākea o nā hiʻohiʻona a hoʻokomo piha i kahi hiʻohiʻona ākea i loko o ke kiʻi. I ka hoʻohālikelike ʻana, loaʻa i nā lens maʻamau kahi kihi pana haiki a kūpono no ka hopu ʻana i nā hiʻohiʻona waena.

Phopena makaʻala

No ka mea ʻoi aku ka nui o ka pana ʻana o ka lens ākea ākea, ʻike ʻia nā mea pili kokoke i ka nui aʻe ka liʻiliʻi o ke kua. Kapa ʻia kēia hopena kuanaʻike ʻo "distortion wide-angle" a hoʻololi i nā mea ma kahi kokoke i ke ʻano a ʻike ʻia.

ʻO ka ʻokoʻa, ʻoi aku ka ʻoiaʻiʻo o ka hopena kuanaʻike o nā lens maʻamau, a ʻoi aku ka pili o ka pili kokoke a me ka hope i ke kūlana nānā maoli.

4.ʻO ka ʻokoʻa ma waena o ka lens ākea ākea a me ka lens fisheye

Aia ka ʻokoʻa ma waena o ka lens ākea ākea a me ka lens fisheye ma ke kahua o ka nānā a me ka hopena distortion:

Hiki ke ʻike ʻia

A leki kihi ākeaʻoi aku ka laulā o ka nānā ʻana ma mua o ka lens maʻamau, e ʻae iā ia e hopu i nā hiʻohiʻona. ʻO kona kihi ʻike maʻamau ma waena o 50 degere a me 85 degere ma kahi pahupaʻi kiʻi piha 35mm.

He ākea loa ka ʻike maka o ka maka iʻa a hiki ke kiʻi i nā hiʻohiʻona ʻoi aku ma mua o 180 degere, a i ʻole nā ​​kiʻi panoramic. No laila, hiki ke ʻoi aku ka nui o kāna kihi ʻike ma mua o ka lens ākea ākea, ʻo ia hoʻi he 180 degere ma kahi pahu pahu piha piha.

Nā kiʻi i paʻi ʻia me ka maka iʻa

Ka hopena distortion

Hiki i nā lens ākea ākea ke hōʻemi i ka distortion a hiki ke hōʻike i nā ʻāpana hiʻohiʻona maoli a me nā ʻano laina. Hoʻonui iki i nā mea kokoke, akā liʻiliʻi ka hopena distortion holoʻokoʻa.

Loaʻa i ka lens fisheye kahi hopena distortion, ʻo ia ka mea i ʻike ʻia e ka hoʻonui ʻia ʻana o nā mea kokoke, ʻoiai e emi ana nā mea mamao, e hopena i kahi hiʻohiʻona curved a spherical, e hōʻike ana i kahi hopena fisheye kū hoʻokahi.

Ke kumu a me nā hiʻohiʻona kūpono

ʻO ka lens ākea ākea e kūpono i nā kiʻi pana e koi ana i kahi ākea ākea, e like me nā hiʻohiʻona, ka hoʻolālā kūlanakauhale, ka pana i loko, a me nā mea'ē aʻe.

ʻO ka ʻokoʻa, kūpono nā lens maka iʻa no ka hana ʻana i nā hopena hiʻohiʻona kūʻokoʻa a hiki ke hana i nā hopena distortion koʻikoʻi i nā hiʻohiʻona kikoʻī, e like me nā wahi liʻiliʻi o loko, nā wahi haʻuki, a i ʻole nā ​​hana noʻeau.
