After playing around with the foldscope, and photographing through it with a Samsung Galaxy Note 4 (Which I highly recommend for this use), I came across some tricks to make shooting easier. Using a light box to illuminate the slide was a good choice as it ensured even illumination. Also, rather than using the focus rings on the foldscope, I found that securing the foldscope down to the light box and then lifting the phone slowly worked well for focusing. This device, the foldscope, really intrigued me. I played around with prepared slides such as the telia at low mag and found that having dense, colored stains help with finding something to focus on; stained botanical slides work very well as subjects for the foldscope. But, what else is great about this portable device is that it can be used without staining in the field for diagnosis purposes as seen in the following images:
