I think the answer is social documentary photography. Riis wanted to expose the problems caused by
urbanization and industrialization. Many
families were living in very harsh conditions.
Through his photographs of the plight of the poor, the government took
action and implemented many programs to improve their condition. Riis also made use of flash photography when
taking these pictures. This made use of
a device that brighten the picture.
The correct answer for the given question above would be the last option. Since expressionists alter the shape of forms, and they use color as <span>an independent expressive element, the artist that served as an inspiration for early expressionist was Vincent van Gogh. Hope this answer helps.</span>
The medium used for that would be acrylic paint. I can tell because I've had experience with acrylics and pant. And I've seen those paintings somewhere, not sure though. I hope this had helped you out.
