RE: filmscanners: Re: looking at the Sun
True, but only a very small amount. UV filters filter only enough to keep
the image from displaying haze and color shift effects but not enough to
protect eyes from the harmful effects over any prolonged period of time like
more than 5 minutes duration or great accumulations of short duration
periods ( Here I am speculating since I do not know if the harmful effects
are cumulative).

Although some would be filtered by UV filter on the lens....
