I'm not a professional photographer, but I love photography. I'm always taking pictures here and there.
The "Freelensing" technique is something I do a lot, and I didn't even know it was called that. My Samsung A12 phone has some features that change the way I take photos, and if you're someone who knows your phone, you should know all its functions.
When I want to apply this technique on my phone, I just have to open my camera and select "Portrait." This option doesn't let me open the lens; I just have to select the intensity of the effect, lower or higher. It then tells me to stay 1 or 1.5 meters away from the subject, and then the magic happens. The lens blurs and focuses on the closest objects, although sometimes it focuses on the farthest objects and blurs everything else.
