Then, he mixed the collodion in preparation for the wet-plate process.

They also had to be prepared to process cumbersome light-sensitive images in cramped wagons. Photographers such as Mathew Brady, Alexander Gardner, and Timothy O'Sullivan found enthusiastic audiences for their images as the shockingly realistic medium piqued America's interests. As the number of photographers increased, the cost of daguerreotypes fell. For portrait photographers with a go-to location, are there parks or interesting buildings that you haven’t tested yet as backdrops?
