I was trying to take pictures (Samsung Note 20, both front and back camera) of the beautiful lights in a cafe in Seoul (Humbolt Cafe, 325-17 Seongsu 2(i)-ga 1(il)-dong, Seongdong-gu, Seoul).
But for some reason, the lines are appearing in front of it. When there is an object in front of the lights, the lines are gone.
What is the reason for this?
The first image, with the black lines, is taken with the following settings:
- Aperture: F2.2
- Shutter speed: 1/588
- Focal length: 3.30 mm
- ISO: 50
- White balance: Auto
- No flash
The second image, with the hand in front of the lamps, has all the same settings as the first except for the shutter speed:
- Shutter speed: 1/130
I took an extra photo to see if it is because of dirt on my lens, but this photo appears to be fine.
