Thanks for the details!

Biofilm is exactly where I tend to find them Yeah, I got that from the video description :D

This video doesn’t have stentors, but it is of my thickest biofilm, a lot of stentors were found in the same sample: https://youtu.be/T3Bbg-ObTok

That video looks really nice! At first I thought it might be phase contrast, but I see from the description that you got creative. Nice job
