This camera app can capture the traces of moving objects and faint light like stars in the night sky.
Extend the shutter speed to 60 seconds, overlay the moving objects in the meantime, and copy them into a single photo.
It captures the flow of the waterfall like a haze and captures the trajectory of nighttime car headlights and firefly light.
You can also focus the light of the stars in the night sky and capture the stars clearly.

You can immediately publish your photos on SNS such as Twitter and Instagram.
