2021 Microscopy Today Micrograph Awards Open Category
Open 1st
Prize. Natural diamond. Surface structure of a natural diamond crystal from Wyoming, USA. Triangular structures known as “trigons” reveal the isometric
crystal structure on the octahedral face of the diamond crystal. Differential interference contrast microscopy image formed from 8 separate focus-stacked images. Image by Nathan Renfro, Gemological Institute of America, Escondido, California, USA.
Another goal of our competition is to honor images that
may not be eligible or competitive in other micrograph con- tests. All types of micrographs are welcome in this competi- tion, whether they were acquired with a light microscope, electron microscope, X-ray microscope, scanning probe microscope, or some other microanalytical tool. Also, some worthy micrographs are published in journals or magazines without a thought of entering them in a competition. By hon- oring published images in a separate category, we hope to encourage microscopists to think about image composition and visual impact in experiment planning and during image
acquisition. Understanding mechanisms and processes oſten requires dynamic imaging acquired by in situ microscopy of all types. Tus, we have established a separate category for video micrographs. Tis category also includes digital animations of reconstructed three-dimensional datasets, for example from cryo-electron microscopy, which is providing new insights into cellular and molecular structures. Our competition is also driven by image quality from a
technical standpoint. Sharpness of image details is important. Imaging of three-dimensional objects with a large depth of field was once the exclusive domain of the scanning electron
Open 2nd
Prize. Feldspars with intergrown graphite. This image tells of a geological event half a billion years ago, when extreme heat deep within the Earth gave
rise to this crystal formation of quartz and feldspar. This rock, from a working quarry in Kerala, India, was studied with colleague Satish Kumar. Petrographic section observed by polarized light microscopy. Image by Bernardo Cesare, University of Padova, Padova, Italy.
