After struggling to record high mag lens work, I decided that I might be simply misunderstanding what I see through the high mag lens. Color saturation, light, and pattern are hard to interpret when we are used to our eyes alone or a low mag lens. Reminds me of the concept someone else shared, that, for tiny organisms, moving through water is like swimming through molasses (for us). Are fewer photons present because of the smaller space? I guess yes, but have an understanding of light and intensity on the level of a child seeing for the first time. Maybe my lens is just dirty! 😉 I’ve included the low mag image along with 4 high mag images of the same paper slide with Foldscope tape front and back. Will be letting students mess with high mag iPad photography next week. They were highly successful at viewing through the LED/high mag setup, and are ready to go!
