The notion of limited editions and the numbered prints that go with them is a notion that developed in the late 19th century. Earlier prints were limited in the number of their impressions solely by market demand or by the maximum number that could be printed by the medium used..
A natural consequence of making prints by hand is difference within the edition when interpretive variations occur when a print from a film negative is scanned in for larger print than can be make in a darkroom. Does that decrease the value of a print because it was printed digitally? Not necessarily, if the print is with in the limited edition number, signed, numbered and has a certificate of authenticity then the value may be more depending on the number of that size of print. More than 8 could be consider to be posters, there for the value decreases. Value can increased with a very small Limited addition such as one or two prints are printed and no others from that film or digital negative are created.
The following are my words and parts from interviews.
My art training began in the 1960s with a foundation in Fine Art at the Laguna School of Art and Design (Laguna Beach, CA) then Chouinards Art School (Los Angeles, CA) where the discovery of many different mediums including photography came about. Moved to San Francisco and continued the of study photography at the Academy of Art and the Art Institute (San Francisco, CA) in the 1970s
"As I see it, a photographer’s negatives and files are, in a sense, his autobiography. More resides there than one is aware of"… As fragmentary and incomplete as the archaeologist's pot sherds, they can be no less telling.” No matter what the viewer sees, one thing is certain: "Abbott’s photographs are not only documents of his life. but more importantly, they serve as documents of our general existence and the life that surrounds us". Abbott chooses to photograph from his heart, which is very different than working with his head. When he sees a scene that stirs his soul, he photographs it. That is how he has been making images for over forty years, he has come to instinctively see texture, light, and shadow in a value scale as well as the composition - which creates a satisfying photograph to him personally. He’s always glad when it’s well received by others".
"The objective here is to get people to see their surroundings in a different way, and not just by taking a quick look but looking deep into what is there and seeing the subject in more than one way"..
Certificate of Authenticity (COA) Standards
A certificate of authenticity (COA) originates from and is signed by the photographer who created the print, or by the publisher of the print, a confirmed established dealer or agent of the photographer.
A valid COA must contain specific details about the image such as what the medium is photography in this case, the exact title of the print, dimensions, details of the edition size if it is a limited edition, the number of photographer proofs and the photographer's signature. A valid certificate of authenticity should contain verifiable documented proof or evidence of why the print is genuine.
All certificates of authenticity must be original documents (not photocopies), hand-signed by the authenticator. Unscrupulous sellers use a legitimate certificate to forge a new one by photocopying or scanning the certificate itself, do some photoshop retouches and then use them to "authenticate" works of print illegally. A statement that a print is genuine is NOT valid proof of authenticity unless made by an established and respected authority or the photographer themselves. That authority's qualifications should be stated on the certificate, or be otherwise easily accessible and verifiable. In case contact information is inadequate and the signature is illegible or unidentifiable, a COA is not acceptable; the source of a COA must be traceable.. If you have any questions about a certificate of authenticity, contact the individual who authored it and get the answers BEFORE you buy the print. When the contact information on a certificate of authenticity is no longer valid or is out-of-date, contact a current authority or expert on the photographer. If however, the certificate was authored by a legitimate authority on the photographer (living or otherwise), it is very likely adequate proof that the print is genuine no matter how long ago it was written.
