Not correct to do that !

"smile, you're on candid camera."

The darkening along the corners of the photos gives it that "shot from a hidden camera" look. Very much like if he was an upskirt voyeur.

Apparently, the only requirements for this to work is a filter with blurry edging and making sure your subject looks upwards and slightly tips their head.

Self taught photographer? More like self taught photoshop filters.
