This line puzzled me. Surely, if each drop of seawater was filled with 1mm length creatures you'd notice?

If we're talking simple math on magnification:
It's very easy to find macro lenses that have 5:1 magnification, meaning that an object is projected onto the sensor 5x it's size. Taking 1.7 mm and projecting that onto a Canon R5 45 MP sensor with 5x magnification gives us something that would be around 1934 pixels in length (just under 1/4th the width of the sensor that is 8192 effective pixels wide).
I think you can convert 5x into 10x or 15x pretty easily without much loss in image quality.
That's not the problem, the problem is getting enough light (without boiling your specimen, which they briefly mention) and nailing the focus. At such magnification, both problems are challenging.

#25I probably shouldn't mention how much seawater I accidentally swallow whenever I'm in the ocean swimming.
Maybe you missed the following, important part:
"These tiny invertebrates can be found in the deepest ocean trenches and the highest alpine lakes, even in damp mosses and wet leaf litter. Walter once got a call from an Orthodox Jewish organization wanting to know if there were pieces of non-kosher creatures floating in the New York City tap water. The answer was yes"

#26I wonder that the commercial model is for endeavours such as this? I guess you collect royalties from people who want to publish the photos, but although you get a one-off wow factor I don't see there being a big market for these kinds of photos. Is it a hobby/pursuit or can you actually make a living doing this kind of thing? P.S. It's a fascinating thing and I love it!
I have the same question over nature and wildlife photography. Maybe there is a royalty model when people license the images or publishing coffee table books. This is like open source work. You do it for the passion and maybe someone will give you enough contracts for a living.

Which was later released on consoles, then the company made games like Flower, Journey and Sky (free on mobile platforms). If you're not into gaming, I'd recommend setting a few hours aside to go through Journey at least.

Many photographers make a living with magazines like NatGeo. And you could also sell prints online.

It could well be a career for "people of means" only, I'd be fascinated if anyone here had any insight into this...

Not every creature is 1mm.
