There are many ways to ruin a picture on Instagram. Of course you can be a pro and use a real cam. But on your phone…
Choose a wrong frame. Use the tunings to make it too dark, too bright. Exaggerate an effect. Use the autofocus in the wrong way (focus on your hand near you, move your phone quickly and trigger fast). In the night, move your phone to blur things. Choose a boring subject. Focus on the wrong level. Etc…
What could be this tool, to ruinspoil something to “see what you get”? It’s an easy risk you can take in pictures, but where else? Poetry? Movies? Ruin an element only to trigger something? Reactions?
Have fun! Bonne journée !

[ Smiles ] Hmm. I do not think that a person would wilfully ruin an Instagram picture of theirs.
For the record, your so-called ruined pictures are a superb work of art!
