What is this, and where did it come from? It's not sourced properly, and pixiv #31855227, which its implying, isn't nude. It isn't strictly a nude filter though because pixiv #31716874 a few posts back from the artist is nude and has the darker background, but no Miho. Did somebody photoshop Miho into the nude version (seems likely because the brighness doesn't line up), did the artist post this somewhere else as a variation? If so is it publicly available, a paid reward, or something else?
