This guide was made specifically for Leica programs and microscopes. The microscope we used to create this how-to guide is the Leica M205 C, consisting of z-stacking capabilities and a motorized column for effortless imaging.
If the final image looks overall blurry, make sure the Iris Diaphragm is turned all the way to the left. Though turning it to the right increases the depth of field, it also lowers the quality of the image. Most seeds will look best with the diaphragm fully open. Only try turning it to the right if you struggle to capture all aspects of the seed in focus, even after playing with contrast and lighting.
