Gigapixel Macro Photography
Background
Motivated by the beauty and scientific value inherent to wood anatomy, and by the obstinate use of flatbed scanners to produce mediocre tree-ring images, we champion gigapixel macro photography as one straightforward and adaptable paradigm to elevate reflected light imaging standards in dendrochronology. Leveraging various emerging technologies, our vision is to achieve high quality and ultra high resolution image archives to complement entire collections of physical specimens. This collaborative project links the UMN GriffinLab & the CLA AISOS. For more information, or to become involved, please contact Daniel Griffin.
Example images
Two ultra-high resolution images are linked below for public viewing. Insets of these images were included as Figure 1 in a paper we have submitted for review:
