The Open Photo Project aims to reduce stigma about consensual non-monogamous relationships. There are many different relationship types which fall under the heading of ethical, consensual non-monogamy but at the heart of it all parties have agreed that each may have romantic and/or sexual relationships with other partners. In one recent study from the US 21% of the study’s participants reported having had some kind of non-monogamous relationship. However the figures could be higher as many people are not open about being in these types of relationships due to the stigma attached. The founder of the project and photographer Erika Kapin explains why she wanted to photograph everyday lives of the non-monogamous.
