How long is too long

13 years 1 week ago #50455 by Ronald McD
I had heard on here that excessively long exposures can fry your sensors (for night photography) my question is how long is too long? How long can I go before I start having to worry about frying my sensor?

You heard wrong. If you need more than a 30 minute exposure, just take multiple shots and stack them. If you have a quality, late model camera, sensor will be ok......

Why so serious?

Well what is more important is how much Amp Noise does your camera produce in your images. You can find out by covering your view finder and keeping the lens cap on and exposing at various times. The Amp Noise will be a purple fringing at the edges. Most of the newer sensors are good for quite a bit of time. If your camera has video then what is its maximum video time, that will be your sensors maximum time.

:agree:

For very long exposures I think excessive noise is going to become a problem first, and you'll want to look into techniques such as stacking. If you are using batteries they will run out before you damage your camera. I'd also agree that looking in your camera manual section about video will probably give you some advice on this. If your camera doesn't do video look to your camera manufacturer's website. If they don't cover it there send an email. They will have advice on the matter.
