Can't find any info on sunset shots. Will the Cmos sensor in the Rebel (or any other digi) be damaged if I take sunset pics?

Here's one:

After I took this shot, I noticed a spot on the next image. I haven't seen it again, but I'm concerned. Should I stop looking at the sun? haha.

Seriously tho...will the sensor be damaged?

When it's that low.. I dodn't think so.
I've taken thse shoots too.. and not seen any damage.
Just keep a fast shutter I would imagine.... but if the shot isn't even "blown out" then I can't imagine any way it could be too hot for the CMOS.

Well, it will burn quite some time after your retina, if you look into the sun without protecting your eyes
Don't do that :shock:



The CMOS sensor should be able to handle that well.

After all, the sensor in small digicams is never shielded by a shutter, so it gets a considerable share of sunlight (some hours for every shoot).

Best regards,

DO NOT USE MIRROR LOCKUP THOUGH !
You might dammage it then!

Mirror lockup can damage the shutter if pointed at the sun before it would then maybe damage the CMOS sensor. I would imagine a long time exposure might damage the CMOS sensor, but I don't know that for sure.

If you lock up the mirror, you'll burn the shutter curtain... especially if you have a long fast lens...

Does the Rebel have mirror-up function? I didn't think it did...would be nice tho. Guess I'll dig through the manual...

I never leave the camera pointed at the sun any longer than it takes to get a quick reading and snap the shot. Even at that, I usually meter just off to the side and adjust.

I grew concerned about this after I had to send a webcam back for repair because the tech told me the sensor was damaged from the sun. I know a couple other people that run webcams (I'm at a beach/tourist resort area) and they have had the same problem. These cams use a CCD sensor, so maybe that has something to do with it?

Anyway, the thought occured to me that if it gets toasted, it would be much worse than losing some frames of film.

Yeah, according to the maual, the 500mm f/4 can start a fire!
