A Tasmanian subspecimen of the Eastern rosella (Platycercus eximius diemenensis) exhibiting partial biofluorescence under UV and sunlight.
Shame it didn't attach the photo!
Partial biofluorescence in wild EasternΒ rosellas
The Tasmanian subspecies of the Eastern rosella (Platycercus eximius diemenensis) is a regular visitor to my yard, as it is around much of Tasmania. There is a mated pair that often visit and forage, occasionally they'll hop onto the feeders too.β¦
Read about this foundational work into understanding how changes in nocturnal illumination are impacting animals: fluroscape.com/2025/a-quoll...
An Eastern quoll (Dasyurus viverrinus) under specialised UV illumination, showing the unique biofluorescent adaptations of the specimen. Under normal light, the animal, no larger than a house-cat, appears an ashy taupe adorned with white spots. Under the specialised light, the normally dull russet transforms into a wash of golden apricots and pinks, interspersed with electric and ice blues in the normally white margins. Contrary to assumption, no visible light is used: that is, all of the light and colour visible is the animal and its environment responding to the normally invisible UV.
Ever bumped into a marsupial after dark? Chances are you wouldnβt have if you could see different colours.

Already notched up a few discoveries new to science⦠fluroscape.com/2025/a-quoll...
A tree with snaking, exposed roots stands along a rocky shoreline beside a small lake. In the distance there is a small town, visible only through the lights reflecting across the water. Above there is a rising Milky Way, and below, there is strong red and blue glow wrapping the rocks β biofluorescence transforming the rocks and water.
A rocky outcrop draped in grass is seen in the foreground of a coastal scene, set at the base of a lighthouse with adjoining house. The outcrop is glowing in vibrant orange and blue, exhibiting biofluoresence as lichens and grasses respond to UV light.
A series of trees is seen in a deep black scene. The trees are silhouetted, with the exception of intensely vibrant lichens and bark responding on the trees. The main colour exhibited is intense, neon yellow, earmarked with electric blues and vibrant pinks. They are exhibiting biofluoresence.
In the foreground of a coastal scene, a rocky escarpment is pictured, with the ocean to the left and the coast running into the horizon on the right. Above there is the full moon intensely occluded by salt spray, with a pastel green aurora set above the ocean. The rocks in the foreground are displaying intense red, blue, and orange colouration, exhibiting biofluoresence in response to invisible UV light.
@bennjordan.bsky.social Benn β first, I acknowledge the superiority your spelling. Second, ever been to Australia, specifically Tasmania? Iβm documenting wild spaces using multispectral imaging techniques down here, I think itβd be a nice pairing for your recording trickeryβ¦

After more than 12 months, I can finally release this body of work and something totally new to science; the very first quoll fluorescence in the wild. Have a read: fluroscape.com/2025/a-quoll...
The Central Plateau is looking beautiful! Looking forward to going back for our biogeography field trip later this week with #UTas π§ͺβ°οΈπ
That first photo is rad! Itβd make a great foreground for a weather timelapse.
I hope I can get to use your camera one day for my work, Pawel. It looks exquisite.

Matt is one of the best photographers in Australia, and a hell of a nice guy too. Definitely consider adding him to your feeds.
Hey #Astrophotography peeps! Have you ever or ever thought about using your smartphone to do what you do?
Well, nearly 55,000 others have⦠we are now by far the largest smartphone astrophotography community on the planet. Come check it out: www.facebook.com/share/g/15zU...
No matter what tree you find yourself gathering around, I hope itβs surrounded by the warming presence of love and joy.
Have a lovely holiday season, friends!

βHave friends send random photos of your photos on billboards in other statesβ wasnβt really how I expected to be ending β24βs bingo card.

Sony Ξ±7III, Sony 24-105mm f/4 G OSS, and a whole lot of frames. This is made up of 130 subframes to capture enough light.
Itβs one of the most wonderful cities on earth. It has such a distinctive soul that just breathes through it, I canβt wait to go back.
Ah! I ask because I stayed in the Chicago one back in 2008 and adored it π
Ooh the one in Chicago?
Rachel is one of my good mates, and one of the best astrophotographers on the planet. All round good bloke and supermum to boot, even if she is from the bad side of the Tasmanβ¦
Well thatβs a hell of a review!
Hahah Iβve just decided to start a good review register. That is definitely one of the best compliments Iβve received, cheers! And I did. I figure it was my reward for saving a baby kangaroo on the drive there after the car in front hit it.
Iβd love to see some of your shots!
While most of my βseriousβ imaging is done on my full size cameras, I do a tremendous amount on my #iphone.
Letβs see your phone shots.
Photographers! Show me your astro with lone trees!

I cannot overstate how much of a game-changer DxO PureRAW is for low light photography. If I can push a file from my 5D Mark IV ~3 stops at ISO 12,800 and get this result, fair to say it works.

You got any material that precipitates out as green?
The galactic centre of the Milky Way looms large over Tasmaniaβs Russell Falls on a calm night illuminated only by moonlight. The falls are in intense overflow from 45cm of snow melting, yielding intense spray and icing conditions in the fallβs periphery. There is tree ferns lining the banks, and strong channel agitation in the foreground as chaotic water crashes over the rocks.
Photographers! Letβs see those waterfall shots.

AI has its place in the photography arsenal, much as most tools. But I do have my pride that I can create fantasy without needing to cheat π
Tired of unsightly noise in your photos? Well do I have a solution for you.
