According to Bröllopsguiden, the folk costume went out of fashion towards the end of the 19th century and people started looking more at how the nobility dressed. Since common people could not afford to own a lot of dresses they needed one that could be used for more than one occation so therefor the dress was black up until the 1920's. The bride started carrying a boucet towards the end of the 19th century so we can pin the photo to have been taken somewhere between 1850 and 1920 so far. Wikipedia says that the men held the bouqet from the 18th century and it was not until 1888 that the women held and chose the bouqet so now we have trimmed of almost 40 years. So the picture was taken between 1888 and 1920. The man is wearing a frock coat and those were common up until around 1920 as well.
I am afraid that I will not get any further with this picture but I will keep my eyes open for more information on the photographer.
