I am short sighted and always have to wear either glasses or contact lenses. The optical correction can be seen through the lenses of my glasses as they refract the colourful lines.

**Prompt :**
Deux sphères de verre parfaitement transparentes, posées sur une surface liquide miroir dans un laboratoire futuriste baigné de lumière froide bleu-cyan. À l’intérieur de chaque sphère, un micro-écosystème hyperréaliste : un arbre solitaire aux branches tortueuses, enraciné dans un sol de galets humides, partiellement submergé sous une eau cristalline. La ligne de flottaison coupe l’arbre en deux mondes — au-dessus, l’air immobile chargé de particules lumineuses ; en dessous, une eau calme où la lumière se fracture en reflets liquides.
Entre les deux sphères, des gouttes d’eau en suspension chutent lentement en apesanteur, capturées en ultra slow motion, chacune reflétant l’univers environnant comme des lentilles vivantes. Des ondulations concentriques se propagent à la surface de l’eau sous les sphères, créant un jeu de symétrie hypnotique.
Ambiance visuelle inspirée du cinéma de science-fiction contemplatif, mélange de **macro-photographie**, **optique cinématographique 85mm**, profondeur de champ extrêmement réduite (bokeh crémeux en arrière-plan), rendu **8K hyperréaliste**, textures ultra détaillées (verre, eau, bois, pierre). Éclairage volumétrique avec faisceaux lumineux diffus et particules flottantes visibles, créant une atmosphère presque sacrée.
Palette de couleurs dominée par des bleus profonds, argent métallisé et reflets blancs éclatants. Reflets complexes sur les surfaces vitrées, distorsions optiques subtiles. Composition parfaitement symétrique, centrée, avec une sensation de calme suspendu et de tension silencieuse.
Thématique implicite : dualité, expérimentation, équilibre fragile entre nature et technologie, microcosmes enfermés, illusion de contrôle.
Style visuel : fusion entre **Blade Runner 2049**, **Interstellar** et **photographie scientifique haut de gamme**, avec une touche artistique minimaliste.

**Prompt:**
Two perfectly transparent glass spheres resting on a mirror-like liquid surface inside a futuristic laboratory bathed in cold cyan-blue light. Inside each sphere lies a hyperrealistic micro-ecosystem: a solitary tree with twisted, sculptural branches rooted in a bed of wet pebbles, partially submerged in crystal-clear water. The waterline slices the tree into two distinct worlds — above, still air filled with suspended luminous particles; below, calm water where light fractures into fluid reflections.
Between the two spheres, droplets of water hover and fall in slow motion, captured in ultra-high-speed detail, each droplet acting like a tiny lens reflecting the surrounding environment. Gentle concentric ripples spread across the liquid surface beneath the spheres, creating a hypnotic symmetry.
Visual atmosphere inspired by contemplative science fiction cinema, blending **macro photography**, **85mm cinematic lens**, extremely shallow depth of field (creamy bokeh background), **8K hyperrealistic rendering**, ultra-detailed textures (glass, water, wood, stone). Volumetric lighting with soft light beams and visible floating particles, evoking a sacred, almost otherworldly ambiance.
Color palette dominated by deep blues, metallic silver, and bright white highlights. Complex reflections across glass surfaces, subtle optical distortions. Perfectly centered, symmetrical composition, conveying a sense of suspended calm and silent tension.
Underlying themes: duality, experimentation, fragile balance between nature and technology, enclosed microcosms, illusion of control.
Visual style: a fusion of **Blade Runner 2049**, **Interstellar**, and high-end scientific photography, with a minimalist artistic touch.

The big eruption of Mount Corona happened around 3000 years ago. The liquid stone shot out with a tremendous force and covered a big area in the Northeast of Lanzarote Island. The lava cooled out quickly on the surface, but underground it continued to flow towards the Atlantic Ocean. The lava ebbed away, the empty tunnels stayed, building the worlds biggest lava tube. Parts of this tunnel system can be visited on a guided tour. You climb down 50 meters through a huge hole into this mysterious underworld. At the end of the tour you arrive at this spectacular, steep abyss...or is it a reflection? However that may be...the tour guide allowed me to stay longer than the group to take my photographs in a calm and lonely setting.

It appears we are looking up a hill at an Elk with the sky in the background but what we are actually looking at is down a hill with a lake behind her.
For MACRO MONDAYS, this week’s theme: "Corner".
Setting: a 15mm Optical Cube Prism was placed on a white plastic board. The rainbow colours were from refraction and dispersion of sunlight.
HMM!
♥ Thank you very much for your visits, faves, and kind comments ♥
Lamp in the waiting room of my ophthalmologist. The light is originally much softer on the eyes, but I am in the mood to slide, and I suddenly have a crave for a creamsicle.😁 HSS!
The Root Problem: Perspective Distortion
When you tilt a camera (especially upward at a building), parallel lines in reality appear to converge in the image. This is due to how light rays hit the sensor.
Vertical lines → lean inward (the “falling buildings” effect)
Objects closer to the camera → look disproportionately larger
This is governed by basic projective geometry—not a flaw, just how perspective works.
The “Trick”: Re-mapping the Image
Perspective correction tools (in apps like Adobe Lightroom or Photoshop) apply a mathematical transformation to the image.
Think of it like this:
The original photo is a distorted grid
The software stretches, compresses, and skews parts of that grid
It forces lines that should be parallel (like building edges) to become parallel again
This transformation is often a homography (a 2D projective transform).
Why It Looks Like “Optical Trickery”
The illusion comes from how your brain interprets visual cues:
a. Restoring “Expected Reality”
Your brain expects:
Vertical lines to be vertical
Rectangles to look rectangular
When software enforces this, the image feels “correct”—even though it’s been heavily warped.
b. Stretching Space Unevenly
To fix perspective:
The top of the image is often stretched wider
The bottom may be compressed
This creates subtle side effects:
People or objects near edges can look slightly distorted
Resolution is uneven (some areas lose detail)

Despite my best efforts it still looks a bit weird.

I was playing around w/ framing up the Milky Way on this particular night... so is the tree absorbing the Milky Way?... or is the Milky Way absorbing the tree? lol

Thank you for taking a look at my images. I appreciate it.
Although beautiful statues and cathedrals filled my brain during travels to Italy, I found myself enchanted with the architecture of each town we visited. I especially loved the windows with their all the exquisite details.
As I was waiting on the corner for a friend to return from a shop, I looked up and noticed one window across the street seemed to be gleaming. Initially I thought the black shapes were two cats facing each other. A closer look much later actually showed me something totally different.

My usual Wikipedia research came up empty for this product type. If you're curious, here's the manufacturer's product link.
The area shown is about 2" x 2" (50.8mm x 50.8mm).
I am doing something I have not done before on this site and that is, posting the same picture twice. But I am intrigued by the optical illusion in this shot. It was taken in the early morning light which causes our brain to see it differently than it actually is. Here's the science behind it.
Brain's Assumption: The human brain is evolutionarily wired to assume that light, especially from the sun, comes from above.
Shadow Interpretation: When we look at ripples or footprints in the sand, our brain uses the shadows to determine if a feature is raised (a hill or a ripple crest) or indented (a depression or a footprint).
The Illusion: If an image of sand ripples (or dunes) is lit from below (e.g., in a photograph taken from a specific angle or a picture that is inverted), the shadows fall on the "wrong" side. The brain, still assuming the light is from above, misinterprets the shadows, causing the crests to appear as troughs and the troughs to appear as crests. The image appears inverted.
I invite you to look at this shot and tell me if you see ridges and small concave valleys or do do you see rounded crests of sand with narrow valleys. For me it switches back and forth between the two. And for me there is sometimes a third view my brain gives me and that is, the dark shadows become the raised parts of the picture. It may take a minute for your brain to switch from one to the other. When I first look at this shot I see sharp ridges which is an illusion but when I bring my eyes over to the toes of my shoes it switches to what it should be.
I would appreciate hearing about what you experience.

Un'illusione ottica è caratterizzata da immagini percepite visivamente che differiscono dalla realtà oggettiva. Le informazioni raccolte dall'occhio sono trasformate nel cervello per dare una percezione che non coincide con una misura fisica della fonte di stimolo.
Il modo in cui oggetti e colori appaiono dipende fortemente dal loro contesto. Le variabili strutturali e spaziali di una scena possono influenzare l'aspetto e la percezione.
