Thank you very much Jason.

Focus stacking seems to work well for relatively continuous subjects like this, as compared to something like an Usnea with many branches which seem to “confuse” the software I use.

Nice to see dry and wet side-by-side

Nice demonstration of how the pruina is invisible when wet and how the maculae become more visible. Beautiful quality photos!
