Is The Foveon Sensor Still Relevant?

Is The Foveon Sensor Still Relevant?

There is a group of photographers who remain dedicated to using cameras with a Foveon sensor.  In this time of evolving full-frame cameras with new features that increase the automation of “capturing an image” perhaps it is useful to very briefly review...

    Really well- done Erik….take a look at some of the information available via the links below.

    Print-Permanence-Chart-v2-9-19.pdf (digitalsilverimaging.com)

    How Long Will Your Digital Prints Last?You May Be Surprised Page 2 | Shutterbug

    Permanence and durability of digital prints on paper | Request PDF (researchgate.net)

    From the last reference: “Colour pints with a surface protection of polymer varnish or foil protection are very unstable, causing deterioration of colour, contrasts, and colour balance”.

    Evidently many academic institutions have been asking the same questions as we have.

    BTW, the chart from Digital Silver Imaging is quite useful and has references.  If I have an opportunity I will call The Getty Museum in LA and see if the experts there can help.

    I wish we had ready access to a “Paper Chemist” who could provide information about the trace impurities in the paper and in the coatings and the effect of both on permanence. The more one seeks answers the more one finds additional questions….No doubt the realists on this site are asking, “Why Bother” !!

    Thanks Erik.  Sometime back I called Legion Paper and asked about the Moab product….no information available that confirmed any of the claimed advantages concerning protection against pollutants, etc.

    Thanks Erik.  Have you information concerning the “protective” effect in preventing fading of colors or mitigating the effects of pollution?  One would of course like to believe that applying a protective spray has wide-spread benefits.  Nevertheless, where is the evidence?  BTW one also wonders about the polluting and deleterious effects of the volatile chemicals in the spray.

    I am also framing without glazing and worry about damage to prints made on various papers-most often washi or mat papers.

    The value of Protective Sprays has become somewhat confusing to me Eric.  Are the sprays meant to protect against physical trauma or against fading caused by environmental agents such as sun light and pollutants-or both?

    I have tried to find rigorous objective studies that confirm the value of various brands of protective print sprays but have been unable to find any such studies.  Yet the value of such sprays continue to be referenced and praised.  Do you-or anyone reading my comments- happen to know of any studies that verify the “value” of protective sprays.  I believe I asked on another forum but received no such references.
