- Zonă luminoasă care încercuiește imaginea fotografică a unui punct strălucitor DEX - by Veronica Lupascu
- Example sentence(s)
- si am vazut un fenomen optic rar - un halo in jurul soarelui! Se formeaza un halo atunci cand refractia razelor luminoase se face pe cristale de gheata si nu pe picaturi de apa, ca in cazul curcubeului. Fara un filtru la aparatul foto, sau macar niste ochelari speciali, nu poti observa decat niste arce ale haloului circular. - Blog
by Veronica Lupascu - Noapte cu Stele. A fost denumită astfel pentru că amintea astronomilor de pictura lui Van Gogh cu acelaşi nume. Este un halo de lumină din jurul unei stele din galaxia noastră. - Stiinta azi

- Definition(s)
- Trying to remember the photography classes I took years ago, the most familiar term it comes to my mind is 'halo,' which corresponds to the second meaning of halation in the Online Merriam-Webster Dictionary (http://www.merriam-webster.com/dictionary/halation).
ha•la•tion n.
1. A blurring or spreading of light around bright areas on a photographic image.
2. A glow around a bright object on a television screen.
In some cases, instead of 'halo,' it is possible to use 'auréola,' both terms relating to rounded light/ optical effects. The Portuguese definition of 'halo' can be found at Priberam's Dicionário da Língua Portuguesa (http://www.priberam.pt/DLPO/default.aspx?pal=halo):
halo
(latim halos, -o, do grego latim hálos, -o, eira, grão na eira, disco do Sol ou da Lua)
s. m.
1. Círculo luminoso que às vezes se nota em volta do Sol e de alguns planetas devido a certo estado da atmosfera.
2. Círculo que rodeia o mamilo.
3. Fig. Auréola.
4. Brilho
5. Prestígio, glória.
I came across a few options to translate halation as a technical photography term:
1) First, it is possible to keep the original term in English, although most of the occurrences I found of this use actually refer to 'anti-halation' (backing or coating) and not to the word 'halation' alone
2) The Dicionário Editora de Português-Inglês (Porto Editora, 2009) translates halation as 'halação,' but gives no examples and no further explanation (http://www.infopedia.pt/portugues-ingles/hala%C3%A7%C3%A3o )
3) Professor Enio Leite Alves, from Sao Paulo University (Usp), mentions 'halo,' 'ofuscamento,' and 'efeito de neblina luminosa' on his 'Glossário Fotográfico' (http://stoa.usp.br/escolafocus/weblog/49774.html)
4) Finally, the most common Portuguese terms used in reference to halation seem to be 'halo' (again) and 'efeito de halo.' The latter is also used in psychological studies, I believe, as well as in graphic arts (referring to the printing process) but it appears quite frequently in photography.

- Example sentence(s)
- "Finalmente, ligada à base de acetato por mais uma camada de adesivo, vem a camada anti-halo, que tem por finalidade evitar que os raios de luz que atravessam a emulsão sejam refletidos e causem halos nas partes claras da fotografia." - Girafamania
by Lu M (X) - "Uma diferença quase imperceptível na grossura da gelatina pode resultar, dependendo da iluminação da cena, num ponto ou numa faixa difusa no material projetado; numa área mais clara dentro do enquadramento; numa área opaca; ou num efeito de halo." - Mnemocine
