Why did photographers travel with their darkrooms in the 1800's? (choose all that apply)

a It was too dangerous to mix photo chemicals in a downtown building

b They sold advertisements on the sides of the big wagons and they made most of their money that way.

c The photograph had to be made and developed while the chemicals were still wet

d The chemicals had to be applied to a plate, in the dark.

d The chemicals had to be applied to a plate, in the dark.

c The photograph had to be made and developed while the chemicals were still wet

Explanation:

Darkrooms used red lighting to allow photographers to control light carefully, so that light-sensitive photographic paper would not become overexposed and ruin the pictures during the developing process

This meant that the photographer had to have a dark room with him, as well as various dangerous chemicals that were necessary for the development of the photo.
