Does exposing your digital camera's sensor to frequent long exposure will spoils it? I'm just curios cause somehow my digicam had noises at lower ISOs that usually doesn't have noises.

If exposing to bright light ie the sun, yes, the sensor might be damaged due to long exposure. But in normal/low light situation I dont think it won't cause any problem.

Is the photo underexposed?

Long exposure will create noise even at the lowest ISO setting. Same applies to DSLR's sensor.

No, not at all. Sometimes I like to take long exposed night shots. It's just I'm worried that keeping the sensor open long too frequently will damage it.

Dude,

Perhaps you should read what i typed again. Why would anyone want to do a long exposure shot towards the sun anyway?

nah its not going to be a problem just do it, but dont expose it directly to sun light, you'll burn the sensor

try expose for 2-5 mins in a dark place where the moon is the only light, you'll be pleased with the results

Thanks for the answer radical. I needed that. Gonna go shoot some more night exposure .

No no, if you look at the histogram where do the highest points lie? In the middle 2 segments? If your highlights are in the leftmost segment then you underexposed your shot and you'll find that noise becomes a lot more apparent in the dark tones.

no problem man

only 1 word can describe it, its fun

Did some experiment myself, but needed to do more, now that im in my holidays, there's plenty of time going to get my remote shutter only

haha... 2 - 5 mins is long man... u can even go take a drink first. or a pee.. LOL.... u can do long exposures on anything except for the sun... =)

for the sun you need something different. Like a 13stops ND filter

Get several ND filters and stack them all up!

^it depends. If you use cokin filters then its not advisable to do so, you end up getting purple'ish images.

Cokin filter very ugly ler with the adapter summore, I wish they had simple screw type solution.

Haha, ugly meh? screw type very limted(im refering to those grads).

But i really think they should develop those screw type for ND filters "

And why would point at the sun burn the sensor? Basically the sensor has a range electrical range whereby each pixel emits a max range of volts. This range of volts will basically clip (when you have an overexposed picture) or overexposed section of the picture.

What a CCD/CMOS does is that they convert light into electrical signals and the range of the volts it produces for each pixel is limited by the sensor itself.

What about solar eclipse ? Pretty nice good picture if could get some. Could post on Reuters. So for solar eclipse 16 stops?

wah if can get solar eclipse would be great.........best if can get this shot

"fish eye - bottom of the photo is the earth and the top there is the eclipse" great shopts

How can one get a 5 minutes exposure when the camera only have 30 seconds max ?

Do have a look.
