We discussed why tintypes were so popular in the 19th century and how come there are so many left of those beautiful pictures.
Well the simple answer is: millions were made.
The picture shows a part of the Scarborough beach somewhere in England around 1855.
On that part of the beach, which is not bigger than a few hundred meters,
you can see about 6-7 photographers making tin types.
That claims it was extremely popular at that time.
The tintype process became very popular in United States particularly during the Civil War They continued to enjoy significant use throughout the 19th century for inexpensive portraits, particularly by street photographers
Tony Richards forwarded me this picture. It shows the same spot at about the same period.
