This allows them to create prints only on demand, or to close the edition after just a few prints have been made. Other photographers create limited editions, marking the edition size and print number on each print. Some editions are relatively small, and the asking price for each print may go up as the edition begins to sell out. For larger editions of 250 or more, artists typically set one relatively reasonable fixed price for all the prints in the edition. Artworks are always valued more highly when they are in original condition, and not damaged by extreme heat or damp.
Many collectors think of a signature as a mark of completion and authenticity.
But photography collectors should keep in mind that many original, fully-realized fine art photographs are unsigned. Fine arts photographers sometimes choose not to detract from the photograph with a signature, or sign inconspicuously on the mat or backing. Signatures can be hard to authenticate, so your best guarantee of authenticity and originality is to purchase your photographs from a reputable fine arts photography dealer such as eyestorm. One reason is that certain works are credited with special artistic or historical importance. Certain photographs seem to define an artist's style, while others mark a compelling departure for that artist.
