Quantitative high-speed imaging of entire developing embryos with simultaneous multiview light-sheet microscopy. Nat. Methods 9, 755–763 (2012). In the present study, we assess the photoluminescence (PL) of Tridacna maxima giant clam iridocytes (embedded in the clams’ outer mantle tissues) as well as of pure guanine, the material which composes the optically active components of the iridocytes. Further, we characterize different properties of T. maxima mantle tissues using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Materials and Methods Collection of Clams The two lights can be set at even powers. The lower light should never be at a higher power than the taller key light. If it is, the image will have unusual shadows from being lit from below. interior of a modern photo studio 1. Shoot — and Troubleshoot There’s no hard and fast rule to just how high and how far from the subject the light needs to be. The height should be above the subject’s head. Don’t position it too high or the light won’t create catchlights.

However, the role of guanine crystals in iridocytes has received attention only recently. Holt et al. (2014) modeled, based on spectral shifts of irradiance with depth into the Tridacna tissue, the photo-protective role of giant clam role iridocytes. The present experimental data extends these efforts by providing evidence that, in addition to reflection, iridocytes in the T. maxima mantle tissues show a clear absorbance of UVR wavelengths (200–400 nm; Figure 4), consistent with the UVR absorption of pure guanine. Therefore, our results identify a dual role of iridocytes, protecting the animal from high-energetic wavelengths (including UVR), while enhancing the flux of PAR to the symbiont by shifting the UVR radiation absorbed into longer wavelengths within the PAR range, where they can be used by the photosynthetic symbionts. Further, our results provided evidence that the re-emitted longer wavelengths are in fact contributed by guanine (as shown in Figure 6B), the material which composes the optically active components of the iridocytes in Tridacninae, as well as similar guanine-containing structures in other animals (e.g., squid, octopus, and chameleon) ( Rohrlich and Rubin, 1975; Cloney and Brocco, 1983; Teyssier et al., 2015).

Once you’ve set up your clamshell lighting just right, you might think you’re done. But there’s more you can do to enhance the scene and create striking images.
