            • 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. Own research - 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 by Lu M (X)

            • Da se u atmosferi događa nešto neobično registrovao je i jedan američki amater-astronom kada je 22.11.2009. snimio Sunce iznad Misisipija i video da zraci formiraju tri halo-efekta, iako Sunce, poznato je, ima samo jedan. Ovaj halo-efekat nastaje kada se zbog prelamanja svetla koje prolazi kroz ledene čestice u atmosferi oko Sunca ili Meseca vidi svetleći oreol. - Tabloid by V&M Stanković
