This took me nearly all day to setup and it was over in about a second. Sure am glad it turned out and I had the correct exposure.

Man vs nature? Happy Earth Day.
filament:
1. a fine thread or wire, heated to glowing, in an incandescent light bulb or a thermionic valve
2. The stalk of a stamen in a flower, supporting the anther.

Going back to this picture taken in January 2016, I wanted to try a black & white conversion with the aim to emphasise the shiny white and the filigrane structure.

La estrella de Euastrum hoy se ha adelantado a su tiempo luciendo colores de otoño. Euastrum se abre sobre los fondos poco profundos del Lago de Sanabria, entre filamentos de Nitella y, recortada como una flor de pétalos de arcoÃris, salpicando las nubes de sedimentos que contienen escrita la historia reciente del Lago contada en cascarones vacÃos de todos los seres que habitaron y dieron vida a estas aguas.
La perfecta simetrÃa de los désmidos asegura su equilibrio en el agua y con él el perfecto reparto de la luz del Sol, imprescindible para que puedan realizar la fotosÃntesis y con ello, cobrarse en nutrientes la energÃa que llega a través de la luz.
La supervivencia de todos los désmidos está asegurada a través de diferentes procesos de reproducción, generalmente asexual, si las condiciones son favorables para su vida y sexual en un proceso lento y complejo cuando es necesario garantizar que aunque el futuro próximo sea incierto, el lejano traerá nueva oportunidades para vivir
Igual que la mayor parte de las algas de la familia de los désmidos, Euastrum parece mirarse en un espejo creando una pareja de siameses verdes unidos por un mismo corazón en un juego de simetrÃa en el que la supervivencia hoy y la del futuro están bañadas de esta belleza sencilla e intensa.
El contorno de Euastrum verrucosum es más complejo y el de su hermanos Euastrum didelta y Euastrum ansatum y casi con tanta filigrana como el de Euastrum oblongum, pero todos ellos están marcados por el juego de simetrÃa que caracteriza al resto de componentes de la familia de estas estrellas de agua como Micrasterias, Closterium, Cosmarium, Staurastrum, etc.
El género Euastrum está representado por cerca de dos mil taxones de los que cerca de doscientos han sido reconocidos como especie. Se puede diferenciar del resto de los géneros de la familia de los désmidos por presentar una hendidura en sus extremos. Las células de Euastrum son algo aplanadas y su contorno suele variar entre las formas poligonales y cortas como ésta y otras y otras más alargadas y casi de contorno triangular.
Una gruesa capa transparente, adornada con sinuosos valles, espinas o botoncitos esculpidos y fabricada con celulosa y pectina protege el cuerpo de estas hermosas algas y les ayuda a flotar y a desplazarse lentamente tanto flotando como por los fondos en los que habitan.
Euastrum verrrucosum , como muchos otros désmidos, se encuentra repartido por todo el globo pero prefiere para vivir aguas algo ácidas, a pesar de su amplia distribución nunca llega a ser una especie abundante.
Las formas que pueden presentar las algas de esta especie son variadas y ésta, representada en el Lago de Sanabria corresponde a la la variedad alatum que se cita por vez primera en estas aguas, después de que en el año 2009, también a través de esta galerÃa se citase por vez primera en la Laguna de Peces.
Margalef la encontró en la década de los años 50 en las lagunas altas de Segundera y la presencia en el Lago se deba muy probablemente, igual que la de otros désmidos, a que las aguas del Tera, Cárdenas y Segundera, las recogen en las zonas altas de la Sierra desde donde son transportadas al Lago
La imagen, tomada a 400 aumentos con la técnica de campo oscuro y polarización procede de una muestra recogida el dÃa 31 de julio de 2014 junto a la Isla de Moras a 5 metros de profundidad en el Lago de Sanabria (Zamora) por Ismael y Laura desde el catamarán Helios Sanabria el primer catamarán del mundo propulsado por energÃa eólica y solar.

A dark, solar filament hovered above the Sun's surface, extending across more than half the Sun (Feb. 7-10, 2015). If that filament were straightened out, it would be more than 533,000 miles long, longer than 67 Earths. These images were taken in a wavelength of extreme ultraviolet wavelength of light of material heated to about 60,000 degrees C. Filaments are cooler clouds of particles tethered above the Sun by powerful magnetic forces. Though this one has been fairly stable for many days, they are liable to break apart at any time.

The light bulb again 2x shot of part of the filament. impossible to shoot without reflections so made a bit of a mess cleaning it up but enjoyed myself in a sad sort of way.
Strobist: Canon 430EX with blue gel on background, full power. Using canon cord so as to use high-speed mode (1/3200 shutter, f32, ISO 100).
It's been a while since I posted a photo from our monthly theme photo wall where I work. So for the month of June the theme is an easy one, "Light". I took it literally.
Each month where I work we have a picture theme. The company provides matted frames for 8x10 prints. The pictures hang on a wall in a well lit hallway past offices to the conference room. We pull a theme from a hat. We don't "judge." We don't put our names on our prints. Anyone can participate in any theme or not. We do a quick critique each month too. So far, it's lots of fun and we are all getting into it.
A dark, elongated filament rose up and broke to the lower left and out from the sun (Apr.9-10, 2017). Filaments are cooler clouds of plasma tethered above the sun's surface by magnetic forces. They are notoriously unstable and tend not to last more than a few days before they collapse into the sun or break away into space. The video, taken in extreme ultraviolet light, covers about nine hours of activity. Credit: Solar Dynamics Observatory, NASA.
This is my first Eskimo photo, it was a very challenging object to photo also it has a very small FOV in the sky.
The Eskimo Nebula (NGC 2392), also known as the Clown face Nebula or Caldwell 39,
is a bipolar double-shell planetary nebula (PN).
It was discovered by astronomer William Herschel in 1787. The formation resembles a person's head surrounded by a parka hood.
It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star.
The outer disk contains unusual light-year-long filaments.(Wikipedia)

added dells and dents and made the welding lines less perfect.
the "holes" for eyes and mouth are unfortunately less visible now. that's why I painted them black with a permanent marker.
the pink arrows point to a dell that is going around the whole helmet. this was there before but became more prominent with the silver colored filament. will try to fix this.
also you can see the newest iterations of the "gloves" and the lower armor. the upper armor turned out bad...so not pictured here...
What's happening at the center of elliptical galaxy NGC 4696? There, long tendrils of gas and dust have been imaged in great detail as shown by this recently released image from the Hubble Space Telescope. These filaments appear to connect to the central region of the galaxy, a region thought occupied by a supermassive black hole. Speculation holds that this black hole pumps out energy that heats surrounding gas, pushes out cooler filaments of gas and dust, and shuts down star formation. Balanced by magnetic fields, these filaments then appear to spiral back in toward and eventually circle the central black hole. NGC 4696 is the largest galaxy in the Centaurus Cluster of Galaxies, located about 150 million light years from Earth. The featured image shows a region about 45,000 light years across. via NASA ift.tt/2gaBLeE

Parte de "Atlas de Chile Regionalizado" que estoy exponiendo hasta el 7 de septiembre en la muestra colectiva "Spoilers" en GalerÃa AFA, curada por Ignacio Szmulewicz.
"Atlas de Chile Regionalizado" consiste en el cultivo de distintos tipos de hongos filamentosos sobre 15 contenedores de vidrio, la forma en la que se propagan dichos hongos dibujan cada una de las 15 regiones del paÃs, los hongos están conservados con resina. Fue realizado en conjunto con el laboratorio de MicrobiologÃa del Centro Médico San JoaquÃn.
This decorative large LED Globe had a filament which was just amazing to view in close up. This image was shot using a Stackshot macro rail and no additional lighting. 46 images images were captured and processed through Helicon Focus 7 and Adobe Photoshop CS6.
... have since been cooled.
This Edison Mazda lamp is a prized possession of mine, I've been meaning to shoot it with a real camera ever since I got it. Being as fragile as it is I'm always hesitant to apply power to it's 100+ year old filament, but I thought this was a fitting arrangement. Needless to say I only applied about 20% of it's rated 20 watts to GTS. It's safely tucked away again with it's sister GE Mazda tubular lamp. See comments below for my original iphone shot and link to youtube video.
Way too busy for new photos right now. Here's one from my unposted archive. A supermacro of a wet lily stamen, the two parts - filament and anther - meeting. Pink lily petals provide the background. Very small scale and shallow dof in this. The anther is perhaps 3 mm across. Some crazy chromatic aberration happening here.
