What was the size of a daguerreotype photo?
These plate sizes became standardized and were subsequently used for the photographic formats which followed on the daguerreotype. Plate sizes are still the standard method for referring to the dimensions of these 19th century images. 19th-Century Image Plate Sizes: Whole Plate: 6.5 x 8.5 inches (16.5 x 21.5 cm)
How big is a mammoth daguerreotype plate?
“Mammoth plate” was a size larger than whole plate. Tintypes were commonly produced in what is called “CDV-size”, i.e. the size of a carte-de-visite, or roughly 2.5 x 4 inches (6 x 10 cm). Images in European-style Mounts:
What is the plate size of an image?
An image’s plate size refers to the size of the complete image plate, including portions which may be covered by its mount, and not just the visible portion.

How is the polished plate of a daguerreotype made?
The polished plate is sensitized by exposing it to iodine and bromine fumes. The plate is first suspended in an air tight compartment containing chloride of iodine until the surface of the silvered plate turns yellow. The iodized plate is then suspended face down over chloride of bromine fumes.

What did Daguerre use to make positive pictures?
After the death of Niepce in 1833, Daguerre continued to experiment with copper plates coated with silver iodide to produce direct positive pictures. Daguerre discovered that the latent image on an exposed plate could be brought out or “developed” with the fumes from warmed mercury.
