The potential of the Galaxy S21 & S22 Ultra's periscope camera can be fully utilized with a Moon Portrait Mode inside the Camera app.
We can combine the typical wide angle 1X or 3x lens photos with the 10X periscope lens/100x zoom moon shots, and combine these photos to create one photo, as a portait photo with the moon in the background.
So for instance, firstly the camera asks us to take a photo of the Moon using the 10x periscope lens.
Afterwards it'll ask you to take a portrait photo of a person (with the previous moon shot still in the viewfinder as a reference), and it then stitches both images together to create one Moon portrait photo. We can also decide to blur or edit the moon background if we'd like right after.
This can be a huge game changer for the moon pics taken on Samsung phones, as it combines the best of moon shots & portrait photos, and creates one incredible photo to be shared across social media.
