Three amigos.

  D5300 ir, 80-200mm 2.8 ed. That lens does very well in infrared.

  Question, does depth of field work different in infrared?
Great catch ;)
In UV the wavelength is shorter so a more defined image is possible given the lens permits, for IR I would guess dof is alittle less since it's only IR light waves that are rendered, but most likely it's very little difference,,,

So good! A really superb framing and subject placement, as well as post processing Fons!You must print this large and frame it!

I veered off tangentially from the ever-present chores to do a quick UVIVF (ultraviolet induced visible-light fluorescence) photomacropgraph of the pollen of a Malva moschata. Turned out the stamens and anthers withered so quickly that my attempt of doing a focus stacking at 5X was thwarted. I could only use a narrow sliver of the intended stack leading to an image with a cacophony of chaotic colours and partly sharp detail. I submit it respectfully, nonetheless.

Z7, Laowa 25mm f/2.8 at f/2.8, 5X, UV 365nm LED light ('NEMO'). The resemblance of the pollen  grains to particles of Covid-19 virus is fortuitous.

Birna, that is amazing!  Rather than the speed of withering, I would wonder how the aquatic plants could stand still in the water during the stacking.

They usually are suspended in water. However, shooting through an air-water interface makes UVIVF well-nigh impossible. Frankly, I hadn't expected the Malva flower to wither this quickly as the entire stack was shot in a 5 minutes interval. But it certainly did and made hopeless for Zerene Stacker to track and correct the changes.

Oh, sorry, I took it granted that you were shooting an aquatic plant.  That said, it is indeed surprising that even the terrestrial flower withers so quickly that it couldn't stand for the duration of stacking.

My new desert island camera and tiny carbon tripod quickly become my everyday camera:

Interesting.
I've been out walking more and more this year and often only have my phone with me.
I like the combo you're using Aerobat

too bad, that empty sky... but the variety of tree colours was attractive. Df, Noct Nikkor @f/8

It's lovely Airy.
Plus even the curves of the building have some grace about them

Beautiful & mind boggling
The mix of colours plus the shapes and luminescence of the pollen grains are indeed other worldly.
