Micro Video

Spent a while experimenting capturing microscope video clips on the iPhone6s.
The Apple photo app does a reasonable job but I found the free version of 'Moment - Pro Camera' gives plenty of manual control over still and video recording. The second section of the video was shot in 4K. Uploaded as 1080p



I put one small drop of water, from some old rain water which was full of green algae, on a concave blank slide. The largest living thing seen was the rotifer - still far too small to see with the naked eye. Magnification was around 250 times.

Colour fringing at the edge of the video can have two causes:
Phone not perfectly aligned.
The standard for objective lenses says that the centre 60% should be sharp but the outer 40% will show signs of softer focus and possible colour fringing.
