I accidentally held down the photoshoot button on my phone and ended up with a sequence of photos of the same scene taken over about 1 second. Interestingly the series of photos contains two very different styles of image:...
It’s called HDR (High Dynamic Range) photography. Your phone is taking three pictures: one at a medium exposure, one at a bit higher exposure and one at a bit lower exposure.
The higher exposed picture will have a blown-out sky, but more detail in the darker area, while the lower-exposed one will have a correctly exposed sky with the darker areas underexposed.
These pictures are then combined by taking the correctly exposed areas of each picture, i.e. the sky from the low-exposure picture and the shadows from the high-exposure one, giving you a single picture without over- or underexposed areas.
I don’t know about OpenCamera, but you should be able to select the size of the exposure bracket, meaning how much higher or lower the different pictures are exposed.
I've discovered that my phone camera is doing some magic processing. Do you know what it's called?
