In this video, we show you a real-life filter. It is placed in front of the smartphone camera in two minutes and allows for great retro-style photos.
For this tech hack, you will need:
- a pin
- scissors
- a piece of cardboard
- a few thin strips of tape
Step 1
Cut a small, square piece of cardboard. It must be able to properly cover your smartphone camera.

Step 2
Use the pin to make a small hole in the center of the cardboard.

Step 3
Now, secure the cardboard with the hole centered on the smartphone camera. This creates a great vignette effect when taking photos.
