History
What is the difference between a photographic negative and a print?
A negative is an intermediate image that can produce positives; the print is a separate object made from it.
Photography has often separated the exposure from the finished object. Calotype paper negatives and later glass or film negatives record an image in reversed tonal values that can be used to make positive prints.
The plate itself is the final image and is not a standard negative
A direct-positive plate such as a daguerreotype works differently: the plate itself is the final image and is not a standard negative for ordinary printing. Other processes create positives through contact or chemical development.

A booth strip may combine the camera event and delivered positive
A booth strip may combine the camera event and delivered positive into one customer experience, even if the machine processes an intermediate material internally.

A negative can generate multiple positive prints
A negative can generate multiple positive prints, while a direct-positive object may be the final image itself. This difference affects both preservation and reproduction: a negative is an intermediate master, while a print may be the version a family displayed or passed down. Check the physical support and catalogue terms before describing what survives or how it was made.
