too easy - so not done by god? this statement confuses me.

#32I 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!
Many photographers make a living with magazines like NatGeo. And you could also sell prints online.
You can win a project from NatGeo and/or other organizations.. but that is not permanent income.

#33Earlier quoted context omitted.
Guidance from rabbis varies (no central source of authority in Judaism). Some orthodox rabbis will view the copepods as not kosher and suggest filtering the water. Less orthodox rabbis will say the water is fine because the copepods are not visible to the naked eye.
That frees the vision impaired a bit relative to people with good eyesight from a few things!
Does that mean blind jews can use this as precedent to eat whatever they like?

#34Cool photos, but this makes me not want to drink tap water
Wait until you learn about what's in your intestines/stomach or on your skin...

Wait a moment and think about how you are made of meat.

Looks like some rabbis might allow some liberal interpretation so I guess the answer is it depends… Flexibility is good.

#37> But copepods typically range from about 0.2 to 1.7 millimeters in length, just large enough to magnify using conventional lenses and equipment Does that mean conventional macro camera lenses or a microscope?
For that size I would use a 1X or 4X microscope objective attached to a camera (this is in fact how my DIY automated microscope at home for looking at tardigrades does it).
I don't understand the part about needing high light intensity- at such low magnification, I have to attenuate my LEDs significantly and take extremely short exposures (like, running a 1A LED at 10mA and 1-10us exposures). But I can't fault his results.

Macro photography most likely. Microscope images tend not to have bokehs like the ones in the article. You can use flourescent microscopy to make those glow in the dark images but the field of view is about 2 or 3 orders of magnitude too small for this.
at such low magnification, the depth of field (not field of view) is pretty big, you can usually see significant out-of-focus detail. But normally people just put the sample in a well and cover it with a coverslip, which makes a thin section.

#39I wish there were a way to "productize" this, or automate it at least. I'm imagining some sort of aquarium-like tank you stock with ocean water that is able to maintain the microscopic life, allow them to flourish. Meanwhile, some sort of slow or periodic pump draws aquarium water into an attached, miniature "photography studio" where an appropriate camera+lens feeds a constant live stream to a display or to the web…
My daughter, 18 at the time, "productized" this for me - by buying me for Christmas a cheap digital microscope. We looked around the house for something to look at, and decided to try a drop of water from our aquarium.
