Is there a danger from looking at the sun through the viewfinder ofmy 400d ? .
VERY SERIOUS DANGER. Do not ever do that, unless if the sun is rising or setting..
Can I safely take pictures of nature with the sun included in thepicture, like a sun set..
Yes. To clarify, you CAN take pictures of the sun, even in high noon, as long as.
A) you DO NOT look at it through the viewfinder (it's ok to look at sunrise/sunset).
B) you are taking a reasonable exposure (Taking a 30 sec exposure of the sun will fry the sensor.
Would a UV filter change anything?.
Take care .

Thanks for the answer !.
What would be the best workflow then. To just aim the camera with your guts feeling and hope for the best?.
Also, if a long exposire would fry the sensor, does that means that "looking" at the sun with a P&S camera or a camera that has a live view would also cause damage to the sensor?.
If you have a Coronado PST - personal solar telescope, looking at an photographing the sun is perfectly safe. YOU NEED A SOLAR FILTER. I think some of the telescope companies may have white light filters that will fit a lens. H-Alpha shows bright red/orange, flares, and sunspots. Check out BORG telescopes.

Pointing an unprotected camera lens into the bright sun is a very bad idea. There is the periodic thread on DPR related to melted components in the mirror box resulting from this practice. The camera lens is collecting and concentrating light, in a fashion similar to a magnifying glass that is occasionally used by youngsters to melt things or set a piece of paper on fire..

There's an old saying among astronomers that in life we get two chances to look at the sun through an optical device. One for each eye. You do want to treat the sun with care. It's energy is less intense at sunrise/sunset due to more absorption by the atmosphere, but even then you don't want to stare into it. When high in the sky, the potential for serious, irreprable damage to your central vision can be high. Maybe better just to lean on the burn tool in your image editor..

The sensor itself is silicon and it can take it. The bayer mask which has been placed over it is dye based, and if exposed to the sun for an extended period, it will be damaged. From a users perspective, that's pretty much the same thing since you can't swap in a new Bayer mask..
Having it briefly exposed won't be a problem, but there have been lots of reports of permanent dark streaks caused by the sun making it's way across a digicams sensor when the camera has been left on a tripod, aimed out the window and forgotten about..
