Prunus ilicifolia is one of my favorite California plants! Amazing nectar source, grows in almost any condition, and historically an important food source for indigenous peoples, each of which developed unique ways to mitigate the cyanide in the seed.

Mohavea breviflora is one of only two species in the genus Mohavea whose distribution is small and localized to the Mojave desert. This species is lesser known and Death Valley represents the majority of its range.

This is Platystemon californicus.

I think it's important context for the fluorescence. Correlating the reflected color with fluorescent has more value especially if one wanted to look into pigments or pollinator interaction. Since this flower is bee-pollinated, I imagine that blue fluorescence is relevant!

Cypripedium montanum, an orchid native to western North America where it grows in montane habitats. With a range barely including California, this species is remarkable for being one of few Californian orchids having large flowers.

This quick video shows how reflected UV, blue+green, and #UVIVF combine in my simulation of how bees might perceive a sunflower. No one of these alone gives the whole picture, and even with all three combined there remains considerable nuance to what really is #beevision

Never managed to get a good roast on my test nuts but I still have them waiting when I'm ready to give them more attention. They're larger than coffee beans and it seems like it takes a lot more to get them roasted enough to put through a grinder without damage.

I think for an image like this it's important to see it in full detail so you can visit my website cpburrows.com and try it yourself!

For context this panorama would take up an entire wall of a house even when printed at fine art quality.

Planning to do more of these once I build a new system!

I have spent a lot of time recently trying to get this right but at last I'm happy with it and sharing. This is a 1,240 megapixel micrograph of a flattened Clarkia unguiculata bloom fluorescing under a UV light.

Check out those crazy pollen grains around 150μm wide!

For #worldbeeday here's Ophrys speculum, a member of the #beeorchid genus. This one is pollinated by a wasp when the flower's mimicry of the female tricks the male into attempting mating with it. The metallic lip seems to emulate the reflection of the sky on the female's wings!

I've never observed it with other plants. While they all move from breezes, changes in hydrostatic pressure, and response to light or other stimuli, I've never seen one move this quickly except for flytraps and mimosa pudica which are mechanically triggered.

This subject, a California native poppy species, is one of the most demonstrative examples responding within seconds to the ultraviolet light. My photos kept coming out blurry and I recorded this video to verify my theory.

The video is at 450% speed to exaggerate the effect.

Anacamptis morio orchid is a widespread species which is threatened despite its range. It naturally occurs throughout Europe, Great Britain, and extends to the middle east. Evolution has favored this like many orchids to use deception instead of nectar to attract pollinators.

Woah the fluorescent guttation is so cool!

I adore games where the user structures attacks or functions in the game. Such things as Transistor and Hades from Supergiant, Noita, and even games like Reassembly and Avorion and Spore check the box! Maybe a build a bird to survive weird ecologies would be fun!

Hi Scott! What would you like to know? The process itself is pretty straightforward - 365nm output through a bandpass filter to reduce visible light. Visible fluorescence is captured on conventional camera and lens with optional bandpass filter to eliminate extra UV.

I started working mostly with regionally native plants which meant that it all needed to be self grown, purchased from nurseries, or collected from common wild plants. I've never worked with purchased cut flowers however. Some of the more rare subjects would be ones that I would need to grow myself.

Craig P. Burrows @cpburrowsphoto.bsky.social · Jan 29

I don't know in advance, but I haven't met a plant that didn't have SOME fluorescence yet. Some have consistent patterns like Phacelia always have brightly fluorescent nectar cups and Asteraceae almost always have highly fluorescent pollen.

Going to try to do posts a little more often!
This is Allium neopolitanum, an onion from the Mediterranean which has naturalized throughout the world in similar climates such as here in California. It has potential to become invasive where it has not already.

We checked it out and it seemed to be a couple trees and bushes on fire. FD was on site. Shortly beforehand we saw transformers flash off in the sky in the right direction.

Just a little time lapse made from thumbnails from a day trip last week. Doing explorations for a project and I liked how the frames looked when I scrolled through fast.

Hope you're all doing great!

I posted one of my reels from IG to here and it was brilliant - no stress about aggressive compression and seems like a whole different value platform over the type of content posted.
