Do you sign your photos?

I am not a photographer, but recently I discovered that I enjoy it too much and I have been shooting all around.

Anything, from macro to landscape …

So far only with my phone, all of them original and some of them you could say .. a little bit nice

So, I have started wondering – Do you sign your photos? Should I sign mine?

I usually post my smartphone images without much (or any) editing, would signing them be necessary?

I would appreciate your thoughts 🙂
