Fem gode grunde til at investere i kunst

Certificate of authenticity
Certificate of authenticity

A Certificate of Authenticity is a guarantee certificate for the authenticity of the photograph. The certificate must contain factual information about the artwork e.g. the name of the artist, the title of the artwork, year of creation and dimension.

In addition, the certificate must contain information associating the certificate to the photograph. It can be a hologram that is identical to a corresponding hologram on the backside of the photograph or it can be a small copy of the photograph.

Finally, the certificate must contain the artist’s signature or possibly the signature from the artgallery.

Framing
Framing

Framing can be carried out with many different frames. The frames can be made of different materials. The most common material is wood or aluminium.

The frame can be a standard frame, a floating frame or a frame with a spacer.

Framing can be with or without passepartout.

Mounting on dibond.
Mounting on dibond.

The photograph is pasted directly onto a dibond plate. The plate is a very thin, very stiff artificial plate. The plate is suitable because is does not warp, twist or become distorted. The photograph is mounted into special fittings. You will often see the photograph covered by an acrylic plate og foil.

Mounting on foam board
Mounting on foam board

The photograph is pasted directly onto a foam board. The board is very light and is therefore not very sustainable for bumps. The board may after a while warp. Photographs that are mounted onto a foam board should be framed. The photograph is mounted into special fittings.

Mounting on glass
Mounting on glass

The photographs are pasted directly against the glass. The edges of the glass are polished. The glass is diamond glass that is a colourless and very clear glass type. Glass is very heavy and a photograph of 100 x 120 centimetres mounted onto 6 mm glass weighs around 18 kilograms. The photograph is mounted into special fittings.

Print Techniques - Analog C-Print
Print Techniques - Analog C-Print
Analog C-print is a print wherein the image is developed in a chemical (darkroom) process where the negative is exposed on photographic paper.
Print techniques - Gelatin Silver Print
Print techniques - Gelatin Silver Print

Gelatin Silver print is a printing technique for black-and-white photographs. The technique refers to the surface of the negative consisting of silver bromidethat is stuck in a thin film (originally gelatin). The technology of Gelatin Silver can be used in both analogue photography and for print of digital photographs.

Print Techniques - Inkjet print
Print Techniques - Inkjet print

InkJet print is a technology where ink is sprayed directly onto paper through very, very small nozzles. Inkjet is normally printed in RGB (red, green, blue) in a spectrum of many million nuances. The Inkjet technology is available in different variants and manufacturers under names like Giclée, Didigraph, Iris print, Cromalin, and Pigment print.

Today there are no practical differences with regards to durability, light-sensitivity or fineness between Lambda print and inkjet print. Manufacturers and research estimate that photographs today sustain the colours to a great extent for at least 100 years.

Print techniques - Lambda print
Print techniques - Lambda print

Lambda print is a technology where a laser canon exposes the digital photographs on photographic paper. The paper then undergoes a chemical development process. The laser canon normally exposes three colours RGB (red, green, blue) in a spectrum of many million nuances. The technology can be a little different and depending on the different manufactures it can be called C-print, LightJet, Cibachrome, RA-4, and Dye Destruction.

Today there are no practical differences with regards to durability, light-sensitivity or fineness between Lambda print and inkjet print. Manufacturers and research estimate that photographs today sustain the colours to a great extent for at least 100 years.

Print techniques - Polaroid
Print techniques - Polaroid

Polaroid print is photographs in which both recording, development and fixation is integrated in the film. It is also called instant photo because you have a print immediately after recording. Polaroid photographs were invented in 1972 and became an important media in the democratisation of the art market in the beginning of the 70s. Older Polaroid photographs can be unstable in the colours.

At the moment there is a growing interest for Polaroid photography, perhaps as a reaction to the rapid digital mass photography.
