Gallery Assis - Saturday, November 24th, from noon
SLT until 2:00pm, for the opening of My new series,
"Beyond Perception".
I will have five new pieces featured, which are exclusive to Assis.
There are far too many judgments and misconceptions with everything, though some often carry more then others. But if you take the time to look beyond those, you can see what's really there. I would like you to come have a look for yourself, and tell Me what you see.
While you're here, be sure to have a look around at all the other talented Artists' work.
There is no dress code, just come as you are. Be yourself, be comfortable and have some fun.
I’m often asked about the world that insects can see when people enjoy my UV fluorescence images, often confusing two very different things: UV reflectance and UV fluorescence. This post will hopefully demystify that, with a simple Shasta Daisy!
On the left, we see the visible-light image of the flower. Pretty ordinary! It’s really just here for reference to the images in the center and right. The central image is UV reflectance, and the right image is UV fluorescence. You can see why I do a lot more UV fluorescence work!
UV Reflectance is the direct observation of ultraviolet light. This requires some tricky hardware, you need:
- A camera modified for full spectrum photography (shot with a converted Lumix GX85)
- A bright source of UV light
- A lens that has very good ultraviolet transmission properties
- A VERY good “UV Black” filter that allows for the transmission of ultraviolet light but zero visible or infrared light.
In contrast, for Ultraviolet fluorescence photography, you need:
- A pure ultraviolet light source
UV Reflectance can reveal hidden patterns in flowers that insects are able to perceive along with visible light. They don’t see UV light exclusively, but their vision extends into this spectrum and some flowers take advantage of that. Daisies do not. Sunflowers, on the other hand? Solidly yellow petals to our eyes will reveal a dark bullseye pattern in the ultraviolet spectrum: donkom.ca/bts/DKP_9769-UV.jpg . Marsh Marigolds have a slightly more complex pattern ( www.flickr.com/photos/donkom/34783610615/ , which also shows visible and infrared versions). Not all flowers use this technique of reflecting back UV light to guide insects towards them, and while it is fun to explore the patterns it doesn’t have the same drama and colour as UV fluorescence.
Directly observing UV light is difficult, but UV fluorescence is a much easier subject to tackle. You use your regular camera to collect regular light, albeit in a darkened room. You just need a good pure UV light source that doesn't leak into the visible spectrum which would contaminate the results. When ultraviolet light hits the flower, some of that light excites electrons in the atoms of the flower. Those electrons rise to a higher orbit but very quickly decay back down, and in the process of doing so release energy in the form of… visible light! UV light goes in, visible light in much smaller quantities come out. You camera captures this visible light.
This is “unnatural” in the sense that there is no way to observe this in nature – the sun clearly emits visible and infrared light in far more abundance than ultraviolet light. UV fluorescence is not what insects can see, it’s what no living thing could see without the aid of the inventions of mankind. It’s “real”, but also hidden from reality. And on the other side, there is something elegant about the mostly-black flower that we know to be white to our own perceptions. The world beyond our own reality is worth exploring.
Can you tell I’m going through my shot list for my upcoming book?? This kind of information will be found within the pages of Macro Photography: The Universe at Our Feet, currently being funded on Kickstarter - www.kickstarter.com/projects/donkom/ - it would be great to have your support for the project and also get a copy when it’s out in December!
…. Oh hey, you’re still here? You actually wanted to know MORE about UV reflectance? Sure, here we go.
The lenses with the cheapest cost and best transmission properties can be found on eBay from the seller “igoriginal”: www.ebay.com/itm//273878542781 .
The filters included with that lens are decent, but if you want the very best at cancelling out visible AND infrared light, you need a two filter combo from maxmax.com:
XNite 330C: www.maxmax.com/shopper/product/15065-xnite33052c-x-nite-3...
XNite BP1: h www.maxmax.com/shopper/product/15072-xnitebp152-x-nite-ba...
Those links are for 52mm filters, which would fit on the above-mentioned lens. You’d still need a camera converted to full-spectrum photography, and one of the biggest outfits for that is LifePixel: www.lifepixel.com/?ar=3
Down the rabbit hole you go. :)
I have been thinking about how we look at things that aren't real. I'm talking about spaceships, cars and photoediting.
I mean, we know how a car is supposed to look like. We see them every day, real cars, our brains are tuned to them in terms of how they look and move around us. Spaceships are a different thing, we're not that used to seeing them around. Does that make a difference when making images with a scale model? Is a spaceship an easier sell than a car?
I made an experiment with the Maserati Boomerang model I've been building during the past couple of months.
Which quote has more significance to this image?
This is a gift, it comes with a price
Who is the lamb and who is the knife?
Midas is king and he holds me so tight
And turns me to gold in the sunlight
-Florence & The Machine
Nature's first green is gold,
Her hardest hue to hold.
Her early leafs a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.
-Robert Frost

I decided to try editing this image with paint.
This is the start of a possible series that will explore manual photo editing. Please do not mistake this for a full painting. It's goal is to make the viewer question what it is and what it is not.

"Depth Perception:" Aldous Huxley has stated, "There are things known and there are things unknown, and in between are the doors of perception." Looking into this scene, it became difficult for me to tell the depth of the water; some of the submerged rocks were visible below the surface, but the reflections from the trees and rocks above began to play tricks on my eyes. I did end up crossing the creek and found the deepness varied with the undulating terrain below.
If the doors of perception were cleansed every thing would appear to man as it is, Infinite. For man has closed himself up, till he sees all things thro' narrow chinks of his cavern.

We perceive the world as we see it. Our perception is based on what we see and what we want to see.
The reality is, if you imagine positive, you’ll end up in having a positive image of your surroundings.
Sunsets have always been part of my inspiration, it always attracts my attention, that brings me close to the nature.

Day 5 of the reveals for the G+ Photo Scavenger Hunt. Category: Perception. For this I thought what is more perceptive than the 10th Doctor? The model is a co-worker of mine that does one of the best 10th Doctor's I've seen. The tardis in the background is one of his miniature collectibles that I took a nice close shot of. @tenthdoctormatt
See all of the submissions over here...
I absolutely love the fact that the title is portrayed in the picture.
'Selective perception' is the process by which individuals perceive what they want to in media messages while ignoring opposing viewpoints. It is a broad term to identify the behavior all people exhibit to tend to "see things" based on their particular frame of reference.
Pareidolia is the tendency for incorrect perception of a stimulus as an object, pattern or meaning known to the observer, such as seeing shapes in clouds, seeing faces in inanimate objects or abstract patterns, or hearing hidden messages in music.

Another shot from the lake at Earlswood Common. The way the light has fallen on these shrubs - and the shadows they've created - has left me thinking of something else entirely...
The other two pictures are just for fun but you can click through if you wish

Elle écrivait les rêves qu'elle allait bientôt faire. C'était sa manière de s'arracher au temps présent.
Isn't she a beauty? No, not the photo, this red-backed spider, Latrodectus hasselti. The photo is rubbish. What? Did you expect something better when I was lying on my back and peering up into a control box filled with valves, pipes, filters, wires, solenoids and three messy red-backed spiders. Think yourself lucky that I did this well!
We are all born lucky. The odds against our conception, birth, and survival to adulthood are astronomical. But we did, so let's get on with it.
How many times have I heard: "But you live so far away…couldn't you come here"? Yes, but it's just as far for me, and if you're whining like that, what motivation are you offering? Then there's the "Oh, no you have so many 'poisonous' things out to kill me". The latter might have a grain of truth. Could it be your whining that's motivating that emotion? I don't condone such thoughts, by the way, and we can explore that, if you like.
We have sharks: great white, tiger, bull. All can give you a nasty nip. Consider this: they are cosmopolitan species, not unique to this Great South Land. Could it be the habit of popping into the sparkling warm waters on golden sandy beaches that puts bite-sized temptation in their fishy way more frequently that if the water is murky, brown and frigid? No one will force you to come here and enjoy yourself. That's up to you.
Besides, horses, bees, domestic dogs and lightning kill more people than sharks. It's got something to do with their disinclination to come ashore for a snack. There are no extant predators that fill that role. No wolves, tigers, lions or bears. Okay, there are drop bears. You might get a concussion, a compression fracture of your vertebrae, or a nasty fright. I haven't seen one for a while. You should be safe.
Snakes? Arguably the most dangerous snake in the World is the eastern brown snake. Sea snakes are pretty bad too. But because you've decided to avoid the water, well, stop worrying about them. I've been struck at multiple times by brown snakes. Not once has any of them connected. I wouldn't be writing this if they had; possibly. One bit Bessie outside my door. With a bit of help, she lived. Dangerous? I guess. But you don't see one every day, just occasionally, and usually as they are slithering about on some mission involving a rodent they can swallow. Never has one hunted me for food, or attempted to swallow me. Don't think you can escape by going into the water. They are good swimmers too. Instead, stand still and wait till they go away.
Crocodiles, blue ringed octopus and stingers? See shark, above. Yes you might be stalked by a saltwater crocodile on land, if you are that clumsy that you repeat habitual behaviours, day after day, in the same place, and the salty is hungry. They can wait for you to do something dumb. The slow metabolism that enables that patience also means you just need to go somewhere cooler to avoid them. Oh, and yes, as you are already avoiding water: somewhere cold.
Mass casualty events? There aren't any active volcanoes anywhere you'd know. Ever heard of, err Heard Island? No, I guessed that. If you rank those that have happened, the massacre of our continent's original human inhabitants tops the list; multiple times. Ship wrecks are up there, and hostile foreign aggression, once; other times, not so much. The toll against POW escapees was bigger. Some floods have been deadly, and there's one nasty earthquake that hit a built-up area. That was ugly, and a bridge collapsed when a commuter train hit a bridge stanchion. A family member attended in an official capacity. That left many scars.
Our biggest civilian incident was a deranged individual with a semi-automatic weapon in 1996. Those weapons are banned now. And recently, there was another incident. In between? Nothing on the scale that wears the label mass casualty. Why? You might have to visit to understand that, and take note of the policy and practice which limits the likelihood of these things.
Here's some numbers about mass casualties. You watch the news. You've already seen stuff around the world. Here, we've had two events in 29 years. Every loss was someone, a person of equal value. They worked, paid taxes, studied, had aspirations, were part of the economy and society. We mourn them all. Just in 2025, this tragic year, there has been one event too many in a country of around 27 million lives. One per capita: 1/27,000,000. In a socially comparable country, there has been a mass casualty frequency of 1/875,000 people. Where would you feel safer? Thirty one times safer?
Back with the wildlife, we also have the nastiest venomous spider in the World. This isn't it. The Sydney Funnel-web is endemic to the sandstone country of the Sydney Basin. That's a big area! Yet almost as many people have seen a drop bear as has encountered one of these spiders. They can kill you, as sure as a drop bear can. I'd rather take my chances with the spider. The last verified death by envenomation by a red-backed spider was in 1956. They are so timid, they'll roll up and play dead if you poke them. I poked this one, and the other female here in this control box too. The male ran off somewhere; such is their bravado. I picked both of those girls up and took them away where I could not harm them, and let them go. My greatest discomfort was negotiating the return to vertical after lying supine to get this picture!
Perception and reality can be divergent.
