With Tom’s help, I was able to do my first timelapse experiment on the foldscope, that too in dark-field.
Please look at Tom’s post for instructions to setup the dark-field modality here.
For any Foldscope user (or microscope user for that matter), I think the first Aha! moment is when you see your first image in a microscope. The second is when the object in view is alive, and you actually see normal motion (video-stage). And the last is when you do a time-lapse and are able to visualize extremely slow movements sped-up (time-lapse).
So, if you are a seasoned foldscope user, I encourage you to try the incredible beauty of a time-lapse experiment : )
