Extremely long timelapse sensor damage concern

PostThu Oct 21, 2021 9:25 am

Hi, I have to shoot an extremely long (12h) timelapse, basically a full sunrise/sunset cycle. Since the sensor is fully exposed during this time to more or less direct sunlight, is there any risk of damaging the sensor? Is there anything I could do to prevent such damage? Thanks.

There’s no way this would damage the sensor in any way.

Thank you for your reply. I'm sorry I wasn't very clear, the sun will be in the frame most of the time (so it will probably overheat the sensor?).

Pointing long zoom wide open to the sun, sure you could damage the sensor.

with wide lens less likely so especially if you use ND filter as you probably should anyway.

If the amount of light you let into the sensor is such that it does not over expose the sensor, I do not see how there would be any problems.

Are you pointing it straight into the sun? Otherwise you really won't have to worry. The heat will be dissipated by the fan.

The idea is to capture a dusk-to-dawn sequence, and the sun will eventually enter the frame. As timelapse function seems to be implemented - the sensor is continuously exposed to light, regardless of the recorded frame frequency, which is 1 frame/min in my case. I finally decided to use a photo camera for this particular shot.

Why do you think that a photo sensor should not be damaged against video sensors ?
Also photo sensor is not thought to be exposed to strong light for long time.

The camera won't overheat operating that long.

It COULD be possible to do actual sensor damage (not overheating) but it's very very very unlikely in normal use. It's only high energy focussed light like from a laser that can do that kind of damage and the damage happens in an instant.

Typically the sun is ALWAYS moving across the sensor so it's not in the one place for long enough and usually isn't bright enough for normal use.
