So, is the Light Microscope already quaint ... ?
Are we the Morris Dancers of microscopy?

PostScript:
It’s a reality check, in a positive way ...
We are now even-better equipped to appreciate the artefacts and limitations inherent in optical imaging.

Re: Large SEM of Paralia sulcata
Urk - those SEM images are quite stunning - the detail & complexity is extraordinary.
BUT, all you diatom-botherers must not let this discourage you, rather let it enliven, augment and increase your enjoyment - every session of observation has the chance of revealing that known but as-yet unseen extra detail or perspective that the SEM-Gods serve up to us as the ordinary - whilst in our light-microscopic realm these glimpses retain their magic!
I have the same experience when I view the dreaded SEM images of plant details, especially parts such as the lignification of xylem-vessel cell walls for example. I look back to my light-microscopy images and their necessarily limited content with a touch of regret & envy it's true.. But then I take a second look and appreciate just how many details I AM able to discern from said light-microscope images.... I find that my appreciation of a 'good result' with sections and images is entirely enriched by the realisation of just jow much I AM able to see and preserve as a permanent mount, of this incredible and virtually infinitely-divisible realm of ultra-detail & magnifcation.

Very eloquently put, John
... that’s what I was trying to express, with my clumsy technicalities about artefacts and limitations.

Think not what you can't see that the SEM can, but what you can see that you couldn't before you had a light microscope.

Re: Large SEM of Paralia sulcata
Agree with all above responses, so well expressed (mrsonchus) and may I add a small personal opinion:
The beauty of a light-microscope image of clean diatoms - or even better, a live diatom, on a clean background, as often shown on this forum e.g. by 75RR and others, wins over the well-resolved SEM documentation.
