Alamance
This student is looking at one of the hallmark images of our university: Alamance Academic Building. Her eye acts as a convex mirror. Light is reflected from the outer surface of the eye. The rays from any point on Alamance diverge after reflection from the surface of her eye, as though they were coming from some point deep in her pupil. The image of Alamance is virtual because it lies behind the mirror (eye) at the point where the object’s rays appear to originate. As with most convex spherical mirrors the image of Alamance appears to be upright and smaller than the object.

Convex mirror over the fireplace provides an unusual reflection - several other Landmarks we have stayed in have had mirrors like this.
Rusophycus cryptolithi Osgood, 1970 - trilobite burrow (convex hyporelief) in limestone from the Ordovician of Kentucky, USA.
This is a rare trilobite trace fossil from the famous Cincinnatian Series of the tristate area of southwestern Ohio-southeastern Indiana-northern Kentucky. Trilobites are extinct marine arthropods in Cambrian to Permian rocks. They have a head (cephalon), a multisegmented thorax, and a tail (pygidium). The body is subdivided longitudinally into three lobes - a central axial lobe and two pleural lobes at the sides.
Trilobite walking behavior resulted in trace fossils called Diplichnites. Burrowing behavior, presumably done in the search for food, resulted in distinctive-looking traces called Rusophycus (some consider Rusophycus to be a "resting" burrow). The fossil seen here is a Rusophycus trace made by a Cryptolithus bellulus trilobite (formerly known as Crypolithus tessellatus) (see: www.drydredgers.org/fragcrp1.htm and stratigrafia.org/cincy/fauna/trilobita/Cryptolithus.html ), a "lace collar trilobite".

Convex mirrors only produce one type of image. Upright, virtual images that are smaller than the object. Magnification <1.
It's supposed to be concentric convex but with the framing and color tone it easily can swing between seeing convex or concave. I realize too depending on the angle of light it can make it feel more convex than it should. I guess perception varies in such instance too.
19th century hardwood chest or baul from northern Luzon.
The top is in the convex style, known to northerners as "pirata". Original details, including lanite-wood geometric inlay.
This street sculpture is a mix of wooden/cardboard cuts applied to a outdoor surface. The piece itself is based on a geometric triangular design formulated using a base plane mathematical equation.

Composición de Cóncavas y Convexos
Cinematografía y Artes Audiovisuales en Centro de Diseño Digital.
La concavidad y la convexidad son líneas de trayectoria curvilínea casi formando un semi-circulo o del todo formandolo; una luna cuarto creciente tiene concavidad y convexidad.
En esta serie de fotografías están todas mis fotografías entregadas siguiendo el elemento compositivo y en si las reglas de movimiento, balance y profundidad.
Todas en blanco y negro a 10 x 8" pulgadas, procesando únicamente el brillo y el contraste a gusto.
Como se observa, la simetría siendo mi regla de balance, es la favorita y siempre está en perfecto ritmo con los puntos de fuga, como profundidad. El sangrado como movimiento es débil, no sé si pueda decir que he fallado siguiendo la regla, ya que fue un poco difícil, pero bastante entretenido. Hay otras reglas como la técnica del sistema de zonas, el enmarcado, la perfecta exposición que proporcionan una estabilidad en mi nota final.
Detail of the Prada Aoyama Epicenter Building with its signature diamond-shaped glass panes, which vary between flat, concave and convex “bubbles”.
Jacques Herzog describes these glass panes as “an interactive optical device. Because some of the glass is curved, it seems to move as you walk around it.

Cap, At first convex with rather striped margin, soon flat, lovely chestnut-brown, weakly sticky, mostly 2-5cm in diameter.
Gills, White, then pale yellow, mostly distant.
Stem, At the apex light, towards the base red-to black-brown and minutely velvety, no ring.
Flesh, Yellowish, mild taste and pleasant smell,.
Habitat & distribution, In mild winder, occasionally appears in October in clusters on deciduous wood, mainly on beech, rarely on coniferous wood,...

Looking down into a hemispherical, convex, magnifying, aquarium window at the Sealife Centre, which put on events as part of the 2011 White Night.
Lincoln Street, Denver, CO, as seen in a convex mirror mounted in a parking garage between 13th and 14th.
Vintage plano convex lens, with cool magnifying effect. Most likely a glass lens from an old theater stage light.
Taken with a plano-convex lens (focal length 114mm, diameter 63.5mm) mounted to my Canon T50. Not great results, but they make me excited for what future experimentation will bring.
Thanks to this Flickr group for introducing me to the possibility of homemade lenses. If I ever become good at photography, this will pay off, I swear.
La Fisicromía Cóncavo-Convexa de Carlos Cruz Diez de Plaza Venezuela fue inaugurada en 1982 y restaurada en el 2007 por PDVSA La Estancia bajo el cuidado de José Armando “Nanín” García, quien trabajó con Cruz-Diez por más de quince años. La obra se diseñó como una obra de arte a escala urbana con la función de cubrir los ductos de ventilación del Metro de Caracas en esa plaza. Forma parte de las Fisicromías a escala urbana realizadas por Carlos Cruz-Diez, que establecen un diálogo con su entorno y ofrecen al espectador en movimiento el juego visual de los colores en movimiento aparente. La pieza provee un marco abstracto a una escultura figurativa tradicional: la estatua en bronce de Andrés Bello, realizada por Nicanor Plaza, escultor chileno de finales del siglo XIX.

La plaza Venezuela fue inaugurada en 1940, con la inauguración del Parque los Caobos, el gobierno necesitaba darle popularidad al nuevo parque. Para ello mandó a construir una pequeña redoma con una fuente en el centro de la Avenida Monumental del Este. A mediados de 1945 el gobierno quería una fuente más grande por lo que la Avenida Monumental quedó para siempre dividida en dos por una gran redoma y una fuente a la par.
