This week we show a micrograph of a Dragonfly eye. But it takes quite a bit of work to put an image like this together. The image is captured using a Canon 5D MkII DSLR camera attached to a research trinocular microscope at a magnification of x20. BUT – the whole eye is too big for a single frame so this is in fact a mosaic of 2 frames. But there’s even more that needs to be done. The huge depth of focus is achieved by taking a focus-stacked image and then applying the brilliant Helicon Focus software to create what almost looks like an SEM image (due to the huge depth of focus). So both frames are individually focus-stacked and then they are combined in Adobe Photoshop to give the final image you see here.
