Partial biofluorescence in wild Eastern 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.…

Ever bumped into a marsupial after dark? Chances are you wouldn’t have if you could see different colours. #biofluorescence #nature #science

@bennjordan.bsky.social Benn – first, I acknowledge the superiority your spelling. Second, ever been to Australia, specifically Tasmania? I’m documenting wild spaces using multispectral imaging techniques down here, I think it’d be a nice pairing for your recording trickery…

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 🧪⛰️🚌

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 it’s surrounded by the warming presence of love and joy. Have a lovely holiday season, friends! ♥️🧚🏼‍♀️

“Have friends send random photos of your photos on billboards in other states” wasn’t really how I expected to be ending ‘24’s bingo card. #npoty #dontgiveup

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 Tasman…

Well that’s a hell of a review!

While most of my ‘serious’ imaging is done on my full size cameras, I do a tremendous amount on my #iphone. Let’s see your phone shots.

Photographers! Show me your astro with lone trees! #astrophotography

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. www.benjaminalldridge.com/blog/say-goo...

Photographers! Let’s see those waterfall shots. #photography #waterfall

Tired of unsightly noise in your photos? Well do I have a solution for you. www.benjaminalldridge.com/blog/say-goo...

Red handfish conservation has been given another boost, with the establishment of a new breeding node at Seahorse World at Beauty Point, #Tasmania. Learn more: utas.au/RedHandfish 📷: Tyson Bessell IMAS

I’m curious to see what practical effects photographers have been able to achieve in-camera. This is the combination of 3 shots taken back in 2018.

How’s your weekend been, Blueskys?

More fish photos to brighten up Blue Sky. Remember the original fish Twitter games we used to play? Like #EpithetEtymology, #GuessThatFish, and #WrasseWednesday? I’m bringing them all back!

I don’t quite yet have the same reach on here as I did on Twitter, so I’m going to start a new fish game called #EtymologyEpithet, where I explain the etymology (the meaning behind a name) for all of the fishes I’ve described, starting with Cirrhilabrus isosceles, the Pintail Fairywrasse.

If you give a damn about pretty fish, go follow Kai.

I’ve been away all week working so been largely absent from the internet, but I have also been editing in the background too. This is from Tasmania’s stunning Tasmanian Wilderness World Heritage Area on my way home from camping back in June.

BlueSky? More like green, pink, and purple sky. Starting fresh with a recent memorable moment under the Aurora Australis down here in Tasmania. Looking forward to sharing more on here!

Some experiences in life force you to step back a moment and enjoy the ride. Aurora at 40000’ over the edge of Antarctica? One of those, yes.

I’m feeling a lot of goodness here having just made the switch, but some sad news – possible closure of one of the tropical world’s most important field ecology sites, the Daintree Rainforest Observatory and canopy crane in NE Australia. www.jcu.edu.au/daintree #ecology #tropics #botany #zoology

1/2. Many species of reef fish are highly dependent on the 3-dimensional habitat provided by live corals, especially when they are young. After mortality due to bleaching, coral skeletons quickly crumble into rubble. Losses of corals affect entire reef ecosystems.....

I study regime-shifts in ecosystems. The switch from X to Bluesky shows some remarkable parallels - the more people leave X, the more toxic it becomes causing yet more people to leave… the type of reinforcing feedback that causes a tipping-point in nature (and climate) x.com/profterryhug...

Incredible use of the medium, you gotta click through and read the bios go.bsky.app/KDY26rh

🦑 #marineresearch #biofluorescence We've all seen this cool photos of biofluorescent ocean organisms. Heck, you might even rented an underwater black light and taking some of those yourself. Well, now we have a list of 27 species newly identified as biofluorescent

Tell me something cool about your week.

I guess I should explain this. Some animals glow. Some other animals glow, but only under certain light. Here a wild Eastern quoll (Dasyurus viverrinus) is glowing under UV light in this case. This is the first imagery of its kind in the wild.

G’day! I’m Benjamin Alldridge, a photo taker person from Tasmania. I recently won the Landscape category at the Australian Geographic Nature Photographer of the Year for 2024, although astrophotography is my bread and butter. Say g’day 😊

I guess I’m on Bsky now? That’s cool. Howdy gang!

I started designing stuff like 20 years ago, and I worked as a prepress guy for a bunch of years. Haven’t done anything for ages, but it‘a still a buzz to hold a physical design in your hands. Especially when it has @hawkmothmoon.bsky.social’s handiwork all over it.

The homie @teamswiftparrot.bsky.social has just joined, go give him a follow. Dejan is one of the researchers working with Tasmania’s critically endangered Swift Parrot (Lathamus discolor), advocating for protection of their habitat in stands of pristine old growth from anthropogenic threats.

My first… er, sky? blue? Whatevs, as a finalist for the 2023 David Malin Awards. It’s looking likely I’ve swept the smartphone category with 3 in the finals. These three made cut, which is a good result considering I entered 4 shots into this category.

Figure I should introduce myself. What better way to do that than post an incomplete photo of a subject you can’t reveal? I’m Ben, I’m a nerd, and I’m occasionally somebody who uses a camera device. I build software, I shitpost, and I was once banned from a banana farm for a caprine incident.

Now this is how you market.
