Thanks Tom, this is EXTREMELY helpful! Glad Leo made this topic sticky, since I suspect many other beginning WEPS users will have similar questions and your information will drastically shorten their learning curves.
As for the veho, I kept the knife in the clamp for all pictures and put the lens right against the blade.
i don’t quite understand this point. Before you wrote that you were able to take better pictures by attaching the microscope much better to its base. But I interpret the words above as that you still put the lens right against the blade. But then you don’t use the base anymore, do you? So what is the added value then of clamping it to the base? What am I missing?
