Grain Silo #5. Convex Pinhole photo shot using Kodak TMX 100. The convex pinhole camera has an aperture of f/188. The grain silo photos used exposure times ranging from 4 to 8 seconds.
A convex mirror does not offer the best kind of reflection sometimes. It accentuates ones figure in places that the last 6 months has affected. I'm only covering a fraction of the distance since March 2020.
This ride of 20 miles was hard going for the last half.
2D-ECGK₂₁ is a 20-simplex ⟂⌅ which includes all its 210 edge EP.

According to Kardashev, T₇ civilizations exist outside of spacetime and are capable of creating n-verses and destroying them just as easily. It's hard to imagine a story with such civilizations, since their perfection and indestructible nature would offer little conflict potential with lower civilizations. Recipe for paraversal tragedy.
It has been argued that KS may not be relevant or useful for classifying civilizations, assuming that behaviors would become predictable only if and when the correspondent civilizations are fully understood. Also, should a civilization be able to harness E of whatever arbitrarily large scale, such as a metagoogol¹ J, it does not mean that it has likewise developed a commensurate ability to use that E with efficiency. Posit a star system wherein a star-shrouding cloud of pebbles is hosting photosynthetic algæ or bacteria that almost completely surround a star, acquiring and having access to far more than the available E on ♁ either proportionately or in absolute terms: nonetheless, even if it were to completely absorb all E from said star, it would not be called a "technologically more advanced civilization" in virtue of its resource advantage alone.
FRB121102 is believed to be co-located in a DG @ 3E9 ly from ♁ with a low-luminosity AGN, or a previously unknown type of EG source, or a young NS energizing a SN remnant; it is presently in a heightened activity state and follow-on observations are encouraged, particularly @ higher RFs. In 2015-11, Paul Scholz @ McGill found 10 non-periodically repeated FRBs in archival data gathered in 2015-05&06 by ART with 3 times the max PD from a MW source and SP consistent with FRB121102. This finding is possibly ruling out self-destructive and cataclysmic SOEs, such as BHEs or NSCs, thus supporting an origin in a young pulsar, or in a magnetar, or from highly magnetized pulsars travelling through ABs, or from an intermittent RL overflow in a NS-WD binary complex. On 20161216, 6 new FRBs were reported in the same direction. This is the only known instance in which FRBs have been found twice in the same location in space. On 20170826, 15 FRBs from FRB121102 @ 5-8 GHz were detected via GBT data.
NOTES
1. The metagoogol [(1E100!)!=10¹⁰⁰ᵎ!] is the largest named number.

I took the flash to this in daylight and it produced a nice reflection in the drop
Ok so its not a reflection but a inverted image formed by the convex lens (water drop)

LES 403 DINKY TOYS
"C'est au salon de l'automobile d'octobre 1955 que le public, sans cesse plus nombreux, découvre le nouveau modèle phare de Peugeot : la 403.
La sortie de la 403 donne à l'époque un sacré coup de vieux à la 203. Pour répondre à la concurrence sans cesse plus mordante de l'Aronde, le constructeur franc-comtois dévoile cette berline à l'esthétique aussi sage.
Son moteur de 1500 cm3 développant 58 chevaux ne fait pas d'elle un foudre de guerre, mais qu'importe, Peugeot mise sur sa robustesse et sa fiabilité qui permettent de fidéliser sa clientèle. Malgré la sortie de ce nouveau modèle, Peugeot décide de poursuivre la production de la 203.
Encore une fois dans un temps record, Bobigny comble les voeux des jeunes amateurs en sortant la reproduction de la 403. La berline mesure 104 millimètres.
La carrosserie finement moulée en Zamak, possède un plancher en tôle, riveté, maintenant en place les essieux aux roues convexes chromés et chaussées de pneumatiques blancs.
La référence 24B, commercialisée en boîte individuelle jaune illustrée, est , dans premier temps disponible en bleu et noir.
De nouvelles teintes, gris clair et jaune paille, font rapidement leur apparition pour le plus grand bonheur des collectionneurs."

Peugeot 403
From Wikipedia, the free encyclopedia
"The Peugeot 403 is a car produced by French automobile manufacturer Peugeot between May 1955 and October 1966.
A total of 1,214,121 of all types, including commercial models, were produced, making it the first Peugeot to break through the one million barrier."
"The 403 made its debut in saloon body style on 20 April 1955 at the Trocadéro Palace in Paris.
For several months before it was launched numerous 403s, their badges removed, were circulating on the local roads near the manufacturer's PSA Sochaux factory, (...)"
"Styled by Pininfarina, the 403 featured ponton, three-box styling incorporating, except on the most basic models, an opening roof panel.
The collaboration with Pininfarina marked the start of a partnership which would see the Italian designer producing designs for Peugeot, including those many mainstream volume models, for more than fifty years.
Regarding the 403 itself there were persistent rumours that the design was one originally intended for a replacement Fiat 1900 which had been rejected when Turin had decided to defer replacement of the Fiat for another four years.
Unusual in Europe at the time, but appreciated by customers, was the way that the rear doors opened wide - to a full 90 degrees. Also unusual were the windows in the rear doors that opened fully into the door frame to the point where they disappeared, (...)"
"Superseded by the Peugeot 404 in 1960, the 403 remained in production as a budget alternative until 1966."

The carapace is the dorsal (back), convex part of the shell structure of a turtle, consisting of the animal's ribcage combined with dermal bone. The spine and ribs are fused to dermal plates beneath the skin which interlock to form a hard shell. Exterior to the skin the shell is covered by scutes, which are horny plates made of keratin that protect the shell from scrapes and bruises. A keel, a ridge that runs from front to the back of the animal is present in some species, these may be single, paired or even three rows of them. In most turtles the shell is relatively uniform in structure, species variation in general shape and color being the main differences. However the soft shell turtles, pig-nose turtles and the leatherback sea turtle have lost the scutes and reduced the ossification of the shell. This leaves the shell covered only by skin. These are all highly aquatic forms.
This is how my grandpa looks with my new Sigma 10-20 lens...
I had to crop it thoug cause the poor man looked all convexed to the sides!
As I was driving past an industrial estate in Holland. I saw this structure,
a rainbow-coloured 30m high pole advertising the colour photo lab...
Rainbows are all around us, for those who look.
I could not resist a close-up of this, I just like puzzling graphics, this one has an added bonus, when you rotate it, the metal scales go from concave to convex.
THANX, M, (*_*)
This is fascinating....well, at least to me. This is a burl on a tree trunk. The next photo on my stream is the exact same image. I have done nothing to the second photo but turn the first one upside down. But as soon as I did so, the "convex" burl, (which looks a lot like a bear paw) suddenly appears to look concave. Even the individual "claws" look concave, like a track made on soft ground. I assume it appears this way to others and is not due to brain damage on my part. Any theories from you Flickr folks on why this is occurring? I don't remember ever seeing this phenomenon before.

Make a thousand dots inside a circle. Then find the convex hull of all the points, draw it, and remove those points from later consideration. Repeat until you run out of dots.

The dominant feature of the Queen Victoria Building is the centre dome, stained-glass on the inside (as shown) and copper-sheath on the outside.

The car windows above are covered with dark film that is also optically active. Partly polarised skylight passes through the window film and the polarised refection from the polished plastic is coloured.
To view in 3D cross your eyes so that you are seeing three blurred images in a line. Pay attention to the middle image and wait for your brain to refocus your eyes on the monitor. When this happens you will have locked on to the 3D image with the reflections below the transparent upturned plastic dome which is a partial convex mirror.

Shown here are two formations: loafs (convex) and pans (concave). The main grid formation is caused by even cracks formed through sedimentary layers of siltstone, which have been shifted sideways as the earth's crust folds.
Where there is more water, the "cracks" wear away more quickly causing the convex "loaves". Further from the water's edge, salt crystals cause the surface of the squares to wear away more quickly than the cracks (or "joints") causing the pan appearance

I just love the Brazilian congress lines.
The bold and skillful use of curves is a basic feature of the work of Architect Oscar Niemeyer
Oscar Niemeyer says: "It is not the right angle that attracts me, nor the straight line, hard and inflexible, created by man. What attracts me is the free and sensual curve — the curve that I find in the mountains of my country, in the sinuous course of its rivers, in the body of the beloved woman"
Niemeyer was born in Dec 15, 1907 and still works at 103 years old!

Convex or concave reflective backgrounds (or foregrounds) always create a challenge, whether it's glass props, eyeglasses, wine cellar, or windows.
Remedy options: change the angle of the lights or your subject to minimize reflection; make corrections in photoshop; go to light painting techniques; composite images of various exposures; shoot as is and call it art, which is what bad writers do and they call it style.
Here I have a 4'x4' softbox as key light ± 15° CL, umbrella at almost 90° CR, and later added a gridded light behind model to fill the cellar slightly and add a muted hair light.
For my final product in this shoot (not shown), (1) I adjusted the model's head position to minimize reflection on her eyeglasses; a small amount of reflection was important to me. (2) I added a gridded backlight that raked across the wine cellar, bringing it to life. (3) In PS I cloned the reflections on the wine cellar at about 35% opacity, leaving some highlights that are natural, much like the necessary natural highlights in the bottle and glass. (4) I repositioned to exclude the window in the background.
