The pics were actually taken with Zeiss stereomicroscope. I work in a developmental genetics lab so I have access to some imaging equipment. The scope is the Zeiss Stemi 2000 with a digital camera hook-up, the camera is an older Sony (can't remember the model #, but it's not impressive on its own). The froglet pictured is about 3 months old.
... Does anyone know if the darker pores in the skin close-up are the poison glands?
