I'm going to be honest, first I thought "Oh I don't like this photo style", but there were a few photos which looked really great! Especially the last photo. This is something.. powerful? Can't say it properly in English, so I'll say it in Finnish.
Oikeissa kuvissa ja oikein tehtynä tuo on todella voimakas tyylikeino. Kun asiaa miettii, se muistuttaa valokuvan rajaamista, mutta se ei vain rajaa vaan kun asettaa kuvaan "pimeyden" luomaan suuren tyhjän tilan, se vain lisää kuvan vaikuttavuutta.
No nii.
So, yeah I agree, it isn't my preference either, but when it comes to drawing, this is actually what I do a lot with portraits. I am lazy and generally only do half of it :)
I think with refinement and the right images, it works as an emergence from or an absorption into the darkness. It can tell a bit of a story.
