I am a Swedish photographer, who has published photos in Sweden under the names "Sofie Sigrinn" and "Sofie Jansson". I have now decided to start to donate some of my works to Wikimedia Commons, you can find them here. I take a lot of photos, but sometimes it's hard to find the time to organise and upload them. I find that taking portraits is particularly interesting, fun and challenging.
I also make some recordings of PD-songs (or CC-licensed) with a choir I sing in, and I have their blessing to share them with the world (aka giving the recordings a CC-license). As an example you can find the Swedish national anthem (with choir arrangement) here.
Since 2017 I am also a board member of Wikimedia Sverige (WMSE).
