| Hi there, I've been wondering about any risks to my camera when shooting the sun. I know that, obviously, looking at the sun through a digital display is of no risk to my health, but what of my CCD? I've heard of CCD temperature problems before, but never of someone ruining a CCD by shooting the Sun. But when I think about it, a 58mm diameter lens focussing sunlight onto a 3/4" CCD must be pretty taxing in terms of temperature. How much precaution do I need to take? |

Your wrong. Shooting the sun can dammage your eye. Gallaleo went blind by looking at sun spots on the sun through a telescope. And about the ccd question I have no idea. I was wondering that too. Good luck.

| I appreciate the response, but that's absurd. Looking at the Sun through a digital display can no more blind you than looking at the Sun on TV, or looking at a picture of the Sun. |

yes, the sun will damage the CCD, and no, your eyes will not be hurt if you are looking at it though the LCD or a LCD viewfinder.
i read it somewhere online, the ccd can handle a short exposure, but the more shots u take, and the longer the exposure, the more it becomes damaged
something i found while doing some quick searching
"If you use the digital display on a digital camera to look at the digitized
image of the sun, I'm betting there is little chance of damage to your eye ....
Correct! No danger to your eye, but ...
is there specific risk to the camera?
Yes. You could very easily damage the CCD chip inside your camera so that it either doesn't respond properly to light for several minutes, or is permanently damaged. I wouldn't point any camera of my own at the Sun."

| My understanding is that a coupls of seconds of exposure is no problem for the CCD. I have seen (I forget the website as it was about a year ago) where someone had their camera on a tripod and the sun was in the frame and the CCD received significant damage. I assume due to the exposure between shots ? |

| what sort of shots will you get though? Surely it'll be all glary? |

I hope my camera enjoyed it the way I did.

I would guess that the cameras of the literally hunderds of folks here who have sumbmitted photos with the sun in the frame are still working fine. A short exposure will do absolutely no harm.
I wouldn't put a non-SLR cam on a tripod and let the sun be focused on a single spot on the ccd for an extended period (without a proper solar filter) however.
An SLR is a bit diferent. The sensor is exposed only during the shot, otherwise the light is directed up through the viewfinder. This will protect the sensor, but of course there is still risk of overheating other parts.
I shot the transit of Venus with my 10D, and I moved the sun out of the frame between shots, even though I had a solar filter on the camera. During shooting, though, the sun was often in the frame for as much as 30 seconds or more.

oh sorry. i missunderstood. i thought you were talking about viewing the sun through a regular viewfinder. no. the lcd screen will not dammage your eyes. sorry.

Kirbic,
I'd love to see your shots of the transit of venus!

Yep, I think the 10D manual specifies not to use aperture preview because it can melt the aperture blades. :-) |
