Why is the exposure time/ shutter speed for my phone capped at 1/2 (half a second)? I would like to take photos with an exposure time of up to 30 seconds. Even when installing other apps, like GCam or Open Camera, it is not possible to increase the exposure time. I have an Fairphone 4 with Android 13.
In the screenshot you can see that the exposure time (S) is at the maximum value.
Do you have the same “issue” as me, or know how to fix it?
Could be a camera module limitation? Fwiw, on my s10+, I can set it to 30s, but I don’t think its a true long exposure anyway. Seems more like a series of short exposures stacked together, with all the noise that goes with it.
Have you tried lowering the resolution to see if you can expose longer?
It’s been a while since I’ve done long exposure photography and composites, but my recollection is that excessive noise is a symptom of long exposure and high ISO, and stacking multiple shorter exposures into a composite will significantly reduce the noise of the final photo.
You could be right, in any case, it was a 30s iso3200 exposure in a dim room, it should have blown out, but instead it was very dim and noisy.
