Chromatic aberration mune mapikicha

Chromatic aberration - imwe mhando mufananidzo nokumonyaniswa kunobva kusakwana optics. Fani iyi imhaka kupararira chiedza parinopfuura kuburikidza izvo. Zviri nokuti kuti mwaranzi vane wavelengths dzakasiyana (mavara akasiyana) vane refractive yakasiyana indekisi. chiedza White ari yaora kupinda chakarondedzera mavara ose, uye mavara vari refracted panguva dzakasiyana pamakona uye pfungwa ndege siyana.

Chromatic aberrations kunotungamirira chimiro ruvara gandiwa yenzvimbo uye mitsetse, izvo zvinoderedza mufananidzo hasha uye kunyanya kuoneka pane kuchinja kusiyana zvinhu. Muenzaniso wakanaka ndiwo muti kana chivakwa akapfura pamusoro pakanyorwa jeka denga. Most zvakasimba kuremara ichi zvinoratidzwa pana rakavhurika aperture.

Modern lenses (kureva lenses zvinopa chromatic aberration) anoshandisa yakaderera-akapararira zvinhu kutapudza refraction uye kunzwisisa. In lenses Nikon vari runotaurwa ED (Extra-Low akapararira) chiratidzo. Nokuti chinangwa ichi anoshandiswa aspherical lenses, vachibvumira mufananidzo pamwe vashomanana urema hwakadaro. Panewo makamera pamwe otomatiki kudzora aberrations.

Asi kana kumbova izvo zvichiri inopa nokumonyaniswa izvi, pane nzira dzakawanda kubata navo. Unogona kushandisa filters, Edit mapikicha mune rimwe vapepeti, kana kuti kushandisa chivhariso-kudzvanyirira chromatic aberration. How kubvisa zvinhu zvaishandiswa izvi uchishandisa Adobe Fhotoshop chirongwa nokukurumidza uye nyore nyore? Mumwe nzira pasi apa.

Zarura mbishi faira muna Photoshop, zvinonzi vakanonga nokuda Adobe Camera Raw. Next, enda neLens Corrections Tab. In parameter Defringe tsanangurai micheto All, ipapo marimu awo zvisinganyanyi yakajeka. Zvino kutanga anozunungusa sliders - wokutanga Red / Cyan kusvikira kusvikira -buda yebhuruu mupendero, ipapo Blue / Yellow kusvikira nhambo apo Ruvara areola kuchapera. All mufananidzo zvagadzirirwa.

Photos muna jpeg pamanyorerwo inogona rakapepetwa yakadaro Sefa sezvo kukanganisa - neLens Kururamiswa. Zviri nyore kubvisa chromatic aberration uye kushandisa chirongwa Adobe Lightroom. Kunakisa yokupedzisira ndechokuti nokubata rimwe bara, unogona kushandisa chete zviruva yose ngaatevedzane yaunonyanya kushandisa.

Nyore, asi kwete nguva dzose nzira yakarurama kubvisa kunetsa zvinoratidza izvi - kuti uchatamisa mufananidzo kuti pamanyorerwo vatema uye chena kana kutanga kuzoposhera nhema uye chena. Uyezve, achiziva kuti izvo anotambura kubva drawback yakadaro, zvinokosha kudzivisa kwepfuti takazarura.

The anowanzodanwa kuitika mune chromatic aberration izvo ane guru multiplicity pamusoro Zoom. The ndechokuti panguva dzakasiyana zvatichiri urefu, kururama aya anoratidzwa munzira dzakasiyana, zviri akaoma uye saka overenga uye aripire zvose zvinobvira zvikanganiso zvakadaro kunzwisisa zano. Ndokusaka lenses ane wakaiswa zvatichiri kureba, kupa mufananidzo nani uye kazhinji zvikuru anodhura kupfuura "Zuma".

Kune dzimwe aberrations ose Manyiminya gadziriro. Paaishandisa idenderedzwa izvo ane idenderedzwa aberration nokuda musiyano iri kuparadzira jekeso pakati uye pamusoro yehombodo yacho izvo. Yakataurwa kuremara ari lubrication achiyeuchidza denderedzwa rechiedza. To kukonzera mufananidzo smearing uye aberrations zvakadai pakoma astigmatism. Mumwe zvakafanana urema, kunyanya cho mhami-angled uye telephoto lenses - Manyiminya kusarurama kuti substantially exaggerates kunzwa pamatanda udzamu. Zvinonzi kwakunoitwa curvature netwumatanda mitsetse uye angava convex uye concave.

aberrations Most Parizvino hakuna kuoma kugadzirisa zviri kwakajeka vapepeti. Asi dzimwe nguva, kunyanya tichiziva michina yacho, zviri nyore kufunga kuti kana kupfura pamwewo kudzivisa zvakaipa kamera angled.
