Multispectral Image Service

MegaVision provides a multi-spectral imaging service which can eliminate these requirements.  This service is an ideal way to apply the technology to selected objects, to explore its more broad application, and to evaluate the technology for possible purchase or lease.

With this service, MegaVision will evaluate the institution’s requirements, assess its resources, and propose an appropriate level of service and equipment to satisfy the requirements.  MegaVision can provide a basic EurekaVision multi-spectral imaging system, together with an expert operator, at an affordable daily rate. 
The expert operator understands the sensitive requirements of cultural heritage institutions and the importance of the imaging that is performed.  Experienced as a photographer as well as an imager, the operator contributes significantly to establishing appropriate layout, optics, lighting, and exposure, guaranteeing that the captured data is highly meaningful, referenced to independent standards, and has the highest signal/noise possible.

Image data that is captured in conjunction with this service is provided to the client.  The data may be saved to appropriate media provided by the client or supplied by MegaVision. Processing, handling, and archiving the data are at the discretion of the client.  Alternatively, MegaVision can provide these services.
MegaVision can additionally arrange for optional scientific investigation and metadata development services though an expert team of independent scientific, data processing, and image processing experts. 

In order to assure meaningful and high quality data, a number of topics should be assessed prior to providing the service.
Some of the questions that will be considered in conjunction with providing this service are:

  1. What type, size, and quantity of objects are desired to be imaged?  MegaVision can help the client decide what is appropriate, set expectations, and clarify limitations.
  2. What resources are available at the imaging site?
  3. Space
  4. Environmental: light, temperature, humidity, power
  5. Copy stand
  6. Easels
  7. Cradles
  8. Photo equipment: light stands, tripods, and grip.
  9. Imaging on floor or in studio
  10. Computer resources including systems, monitors, transportable hard drives, Networking, and image evaluation software.
  11. What are the imaging requirements: visible, UV, IR?
  12. What are the imaging goals?
  13. What are the conservation and preservation goals?What are the reproduction goals?

MegaVision would be delighted to discuss these and other questions you will no doubt have. Please do not hesitate to contact us.

 

 



    Digital imaging’s impact on the guardians of our cultural heritage treasures is profound.  Digital imaging has opened new avenues of research, offered new opportunities of service, and permanently altered perspectives on preservation and conservation.    Digital imaging, while unquestionably nascent, offers such compelling promise that even in its infancy it is being widely deployed and is beginning to deliver on some of its promises.  The many initiatives underway realize to varying degrees the promises; some would be well served with additional careful consideration of the goals.  In a rush to deploy, the digital image data that is collected often leaves much to be desired.
    The EurekaVision system has been developed to provide digital imaging capabilities of sufficient integrity and scope as to more than satisfy a range of goals which other imaging technologies not only do not, but in large measure, cannot, contemplate.  
    The EurekaVision system integrates two previously disparate imaging capabilities: High resolution photography and multi-spectral imaging.    It captures very high resolution, high dynamic range, and highly repeatable digital images over a range of 12 or more spectral bands from the near ultra-violet to the near infra-red.  The spectral bands are created not by using band pass filters to filter the light after it is reflected from the treasured object, but by using  narrow-band LED illumination which subjects the treasure to only the light energy that is required to expose a highly sensitive, unfiltered monochrome sensor.  This strategy results in orders of magnitude reduction in the light energy to which the treasure is exposed, and provides images of unprecedented resolution, registration, quality, and spectral content.  Because the capture process is highly repeatable and because the captured image metadata is replete with not only artifact and collection specific data but also with capture specific detail, the captured images are documentary milestones that will be used not only in current conservation, preservation, scholarly, and reproduction  initiatives, but by those of future generations as well.  The image datasets acquired by the EurekaVision technology become, in and of themselves, assets of scientific and historical value.
