Chromatic aberration i kiʻi

Chromatic aberration - he ano o ke kiʻi ei i kupu mai, mai ka hemahema o optics. O kŰia mea aie a hiki i ka hoopuehu ana o ka malamalama , e like me ka mea hala ae ma ka maka aniani. He aie i ka mea i na kukuna me kekahi mau hawewe (kekahi mau waihoʻoluʻu) i he okoa refractive inideka. ua decomposed White ka malamalama i loko o ka pae ana o nā waihoʻoluʻu a pau, a ua refracted nā kala like 'ole ma kekahi mau pana pua, a kālele ana ma luna o kekahi mau Kekoa.

Chromatic aberrations pinepine alakai i ka helehelena o ke ano contour o ua wahi la a me ka hahau ana, a ho'ēmi i kā kiʻi oi, a pakahi aku la ia kekahi 'ma ka hoʻololi Akä naÿe no nä mea. A hoʻohālike maikaʻi maoli o ka laau a me ka hale pana e ku e ia i ke kāʻei kua o ka ua pń lani. Loa ikaika keia kina ua hōʻike ma hamama puka.

Hoikehonua, nā aniani kaulona ( 'o ia hoʻi nā aniani kaulona hoolako chromatic aberration) hoʻohana haʻahaʻa-lakou hoopuehu oihana mua i haawi emi refraction, a me ka clearer kiʻi. I Nikon o nā aniani kaulona i denoted e Ed (keu-Low lakou hoopuehu) hoailona. No keia mea i hoʻohana aspherical nā aniani kaulona, hiki i ke kiʻi me ka uuku helu o ia mā. Aia mau no hoi Panel me akomi mana o aberrations.

Akā, inā i kekahi maka aniani nō hoakaka mau ei, he nui na aoao e hana me ia. Oe ke pili kānana, hoʻololi kiʻi i loko o kekahi o na me ka luna hoʻoponopono, a me ka hoʻohana 'ana i kekahi polokalamu-uhi chromatic aberration. Pehea e wehe i kēia mau artifacts ka hoʻohana Adobe Fhotoshop polokalamu koke, a hiki wawe ka? Kekahi o na koho i hoikeia ma lalo nei.

E wehe i ka maka waihona ma Photoshop, ka mea, ua lalau aku la ia e Adobe Panel heʻiʻo maka nō. A malaila, e hele i ka maka aniani mākaʻi kiaʻi uku pila. I aiao Defringe hoakaka All kihi, alaila, na apo i emi huali ia. Ano, e hoʻomaka e neʻe maila i nā sliders - mua Red / Cyan a a mae uliuli pihapiha, laila Blue / Yellow a hiki i ka manawa o ke ano o ka areola, e nalo. A pau o ka Hawaii photo Ua makaukau.

Photos ma JPEG waihona hiki ke hoʻoponoponoʻia me ka ka Kānana like ka paha ka nānaina - maka aniani Hoʻoponopono. He oluolu e pakele o chromatic aberration a me ka hoʻohana 'ana i ka polokalamu Adobe Lightroom. I ka lanakila o ka la mahope ka mea ma ka hana maikaʻi i ka hookahi pana, e hiki ke hoʻohana i ka ia palapala koho no ka mea holoʻokoʻa moʻo me ka hoʻononiakahi.

Ka easiest, akā,ʻaʻole e mau ana ka pololei ala, e wehe i kēia mauʻano hoʻonāukiuki artifacts - e hoolilo i ke kiʻi i kaʻeleʻele, a keʻokeʻo waihona a hoʻomaka e pana iʻeleʻele a keʻokeʻo. Eia hou kekahi, ka ike ana i ka maka aniani poino mai ia i ka drawback, ia mea pono e pale pana pua aku makou ākea hamama.

O ka hapanui olelo ana i loko o ka chromatic aberration maka aniani me ka nui multiplicity o ka hoʻokokoke. Ka mea o ia ma kekahi mea nui ia i kona loa, i hoikeia mai i kēia mau ei ma naʻano likeʻole, ia mea paʻakikī loa, a no laila, e huli, a compensate no ka hiki a pau mā i loko o ia i ka luna 'noaia. 'O kēia ke kumu nā aniani kaulona me ka paa mea nui loa, e hāʻawi mai i ka maikaʻi kiʻi, a ua ikaika nui ae pipiʻi ma mua o ka "Zuma" IeAUPIIe, IAa IO.

Aia i nā aberrations o'ōnohi nenoai. I ka hoʻohana 'ana i kekahi spherical maka aniani ka spherical aberration aie i ka likeʻole i loko o ka puunaue ana o ka hoʻomālamalama ma ka waena, a ma luna o nā kihi o ka maka aniani. Kaheaia ma ka kina i loko o ka lubrication haʻahaʻa akula 'Halo. I ka i kiʻi haukaʻe, a aberrations e like me coma a me ka astigmatism. Kekahi maa kina, oi ano o ke akea-huina a me ka telephoto nā aniani kaulona -'ōnohi ei i kekahi exaggerates i ka manao ana o ka wahi ponoi hohonu. Ua Ua hoikeia ma ka curvature o ka pololei laina, a hiki e convex a me ka concave.

Ka hapanui o aberrations Ke mea,ʻaʻole paʻakikī e koho ma ka Kimia me ka luna hoʻoponopono. Akā, i kekahi manawa, o ka oi aku ka ike ole i kona enehana, ka mea hiki, e noonoo ia ka wā pana a ninau hewa pahupaʻiwikiō ka makau o hiki mai.
