RECENART: Next Generation Hyperspectral imaging No Images? Click here NEXT GENERATION HYPERSPECTRAL IMAGING
RECENART has next generation hyperspectral cameras. Our cameras allow even better resolution images of the underdrawings, restorations, vanished texts than before. They can be used to image collections Europe-wide, thanks to our mobile laboratory.
During JUNE, JULY and AUGUST we will be imaging in London, Paris and in Berlin/Fankfurt. If your artworks need imaging or pigment analysis, please contact for times, places and details: laura.aineslahti@recenart.com, +358 40 750 6415 or send a RESEARCH REQUEST. Upper row: Image in normal light, IR-image. Below: hyperspectral images. Painting: PRIVATE COLLECTION CASE: HALONEN The lake landscape was painted on top of a portrait of a gentleman. Up left is the image in normal light, on the right is traditional IR-image. Below hyperspectral images processed with two different spectral parameters are presented. The hyperspectral cameras enable RECENART scientists to analyse artistic process, underdrawings, possible earlier paintings and vanished signatures. Ultimately, also the individual pigments can be identified from the spectral data, which is important when dating the artwork. No other technology can provide such combination of valuable information as hyperspectral imaging analysis.

Painting: PRIVATE COLLECTION CASE: DEATH OF THE VIRGIN MARY When the painting representing three women came under study to RECENART the subject was unclear for the art historians, even to those who were experts in ecclesiastical art. The hyperspectral imaging revealed that the curtain on the upper right of the painting was covering a figure of a woman lying on bed. After imaging the story of the painting started to made sense. It likely that it represents the death of Virgin Mary. Normal photographs provide 3 colours: red, green and blue. This type of information is known as RGB. Similarly, the human eye has only 3 different cell-types which can recognise colours (one for each of the RGB). Hyperspectral cameras used by RECENART can recognise more than 600 different ‘colours’. The cameras also work in a four times wider wavelength area than is seen by the human eye.

The IR-image did not reveal the still-life painting underneath. After hyperspectral imaging the still-life with flowers was seen clearly. The painting is a forgery and painted on top of an old painting. RECENART provides risk management and safety to public and private collectors, galleries, banks, and insurance companies when works of art are traded/bought, insured or used as a collateral.
