A kiss can be such a wonderful thing and it really has an effect on people’s moods. Well, photographer Johanna Siring wanted to see just how big of an effect it has and hopefully capture it in a photo. So, imagine you are at a concert having a good time and a stranger approaches you with a weird request – giving you a kiss. Would you accept it or walk away? However, this is what Johanna did at the Roskilde Festival in Denmark and the changes in people’s faces before and after the kiss are truly amazing! Check the genuine photographies below.
