Grijs weer buiten, een goed moment om eens binnenshuis met fotografie aan de slag te gaan. Naar het voorbeeld van de foto van Sus Bogaerts 'burnout' en de foto van Mark Lukes 'smokin' lightbulb', ontstond mijn plan een gloeilamp te fotograferen. De lamp moet branden, echt branden, zelfs ver-branden. Zolang het glas eromheen zit zal de lamp wel branden maar niet verbranden. Het glas moet er dus vanaf.

Eerst naar de doe-het-zelf winkel. Gloeilampen kopen, originele ouderwetse, is niet eens zo makkelijk, bijna alles is halogeen. Bij de Praxis vind ik wat ik moet hebben, een gloeilamp van 40 Watt. Om te beginnen koop ik 5 stuks. Een glimlach kan ik niet onderdrukken als ik bij de kassa een bonnetje meekrijg, veel te ruilen zal er straks niet overblijven.

Thuisgekomen, veiligheidsbril op, werkhandschoenen aan en de eerste lamp, met een plastic zakje eromheen, tussen de bankschroef. Grote knal, veel gebroken glas en een fitting met daarin iets wat ooit het filament is geweest. De gloeidraadjes bungelen alle kanten op. Duidelijk niet meer als lamp bruikbaar. Een tweede lamp, een derde, vierde en tenslotte ook de laatste knijp ik geheel aan gruzelementen.

Terug naar de Praxis. Het glas kapot maken is het probleem dus niet, de gloeidraad heelhouden wel. Een dikkere gloeidraad zou de oplossing kunnen zijn. Ik besluit een paar 60 Watt en een grote 100 Watt gloeilamp mee te nemen.

De truc met het plastic zakje en de bankschroef vervang ik door de lamp in de doos kapot te knijpen. Eerst een 60 Watt, dat gaat goed. De gloeidraad blijft heel, alleen het glas is vrijwel geheel verdwenen. Nog niet echt het resultaat wat ik zoek. Een poging met de 100 Watter dan maar. Voor de zekerheid het glas eerst beplakt met afplakband. Losjes vastgeplakt om het later nog los te kunnen trekken. De lamp in de doos en het geheel tussen de kaken van de bankschroef. Dat gaat perfect, de dikke gloeidraad beweegt niet eens. In de glazen bol zit een groot gat. Heel voorzichtig het plakband eraf, waardoor hier en daar nog wat glas afbreekt, maar het eindresultaat is prima.

Nu een opstelling maken om de lamp te laten branden. Op een plankje schroef ik een kroonsteen en wat VD-draad aan elkaar. Om te voorkomen dat de lamp in één keer verbrandt zet ik er een dimmer tussen. Heel voorzichtig soldeer ik de lamp aan de draad, zodanig dat tijdens het fotograferen de draden niet zichtbaar zijn. Het stijve VD-draad zorgt ervoor dat de lamp rechtop blijft staan. Als achtergrond gebruik ik zwart etalagekarton en als invulverlichting zet ik twee ledlampen neer.

De techniek is klaar, nu foto’s maken. Eerst wat proefopnames terwijl de lamp nog uit staat. Ik probeer verschillende sluitertijden, diafragma’s en iso-waarden. Ergens in de buurt van de 1/2000 bij f8 en iso 400 lijkt goed te gaan. De camera op motordrive en de dimmer langzaam open draaien… Een lichtflits, een rookpluim en direct draai ik de dimmer weer uit. En nu zoeken tussen de tientallen opnames of dat ene moment daadwerkelijk is vastgelegd. En ja hoor, drie opnames achter elkaar zijn raak. De eerste terwijl de lamp net opgloeit, de tweede zo fel en heet dat er rook opstijgt en de derde als de lamp weer langzaam dooft.

Nog een poging. Weer gelukt. Ik krijg de smaak te pakken en dus nogmaals… nu brandt de lamp echt door. Einde van het fotoexperiment maar een paar mooie opnames rijker.

Illumination: Halogen and white(!) LED (Ra>95)

This is a collage of 8 pictures from the very same scale, but different illumination (white light, but different incident angles and different polarization angles). This leads to the brilliant iridescence of that butterfly.

Visit the album to see some colour variants of the scales!

This butterfly is a true master in structural (physical) colors. Oblique light produces blue/aquamarin, direct illumination results in a yellow reflection. Back-illumination yields red/brown. Thus, depending on illumination angle (and polarization) any mixture between yellow and blue can be obtained. In addition to the iridecent scales, there are several "normal scales" with pigment colours from brown to orange, yellow and almost white. If you are interested in the details, here is a nature article explaining this phenomenon:

This is a crystal of common table salt - sodium chloride, which I recrystallized, to get bigger crystals. In this macro shot the strict geometrical lines of the crystal can be seen, reflecting the alignment of the sodium and chloride ions at an atomic level.

The shot was done with macro rings and a shutter speed of 1/200, and an aperture value of 8. Used a halogen bulb for some additional light.

The wings of aphids are rather thin (about 500nm), and also very rough (+-160nm). Thats why they show up with rather small regions of the same color (in epi-illumination at high magnification), leading to the impression of psychedelic art.

HSS, folks!

Halogen Teal faux crocodile patent skirt, from Nordstrom. They had it paired with a orange blouse on the website so they closest thing I had was this mustard yellow knit top, and yellow patent heels. I then went to black with a T-Neck and CK tall smooth black boots. I like both looks but the black pops the teal and I think this might be a better look for a dinner with freinds. Done without make up so Faceap was used for my makeup and hair

Coming in October!

This Milkyway Galaxy picture was shot when the halogen lights were turned on and there was some fog in the air. This created a beautiful lens flare and the light painting of the halogen bulb made the place colorful. I should say it's a painting done by the nature her self.

Happy Macro Monday!! For the challenge ENERGY (July 28th 2014)

it was too hot to use my makeshift kitchen studio this week - a heatwave took us to 106F in the sunshine at its height! So I had to find another way to approach the challenge!

These small halogen light bulbs measure about 3cm across. I use them in my bedside reading lamps. I shot this in complete dark, with just one tiny blue LED (5mm) as the battery-powered light source. ;o)

Shot with the Sony NEX-6 using the E30mm F3.5 macro lens.

Ventrally on the chelicerae are the fangs, these hollow hypodermic needle-like structures are what delivers the venom into prey or attackers. Shown here is the tip of a tarantula fang, including the single opening of the venom canal on the dorsal side around 700µm from the tip away. You can see the full chelicerae @2,9x here: flic.kr/p/T3Fyaf, or on the anatomy poster linked below. As with hypodermic needles, scorpions and venomous snakes the venom canal never ends at the tip itself, but shortly before it. This prevents the venom canal from getting clogged and is mechanically more stable.

Those multi-use injection needles must be sufficiently tough to withstand the initial impact of a rapid attack, while at the same time they need to be hard and stiff to be able to break the prey’s protective cuticle. Shortly after the molt, they are white and vulnerable, tarantulas can’t use them to eat or perform other tasks, it takes a couple days to harden the fangs. A juvenile Chromatopelma cyaneopubescens (Strand, 1907) after the molt: flic.kr/p/D5CEXT

So what makes them strong enough to brake insect cuticle, which is essentially the same material? The spider takes advantage of a wide range of the available chemical and structural modifications in its cheliceral fangs. One of the secrets are the metals. The tarsal claws, chelicerae, stings and other tools of arthropods contain extraordinary amounts of heavy metals (e.g., zinc, manganese, copper) and halogens like bromine and chlorine. Those Metal–halogen biomaterials are widely distributed, especially among arthropods. The functions of the enriched structures suggest that metal–halogen biomaterials enhance mechanical properties. It is likely that they affect the behavior and ecology of the large fraction of arthropods in which they are found (Schofield, 2005). For example, leaf cutter ants may delay leaf cutting until zinc has hardened their mandibles (Schofield et al. 2002). The same effect may apply to tarantula fangs, as shown above. Other secrets of the strength are the chitin and its structure, the proteins and the water content (Politi et. al. 2012).

This Lighthouse was opened by Mr G O H Giles MP, Member for Wakefield on behalf of the Minister for Transport the Hon R J D Hunt MP, 29 September 1980. It has been an active unmanned light since that day.

The area is known for the treacherous Troubridge Shoal and nearby Marion Reef which by 1911 had claimed nineteen ships and a great loss of life.

It was built after a decision to downgrade the lighthouse on Troubridge Island to a low-powered automatic operation. The Troubridge Island light is now decommissioned.

Special wedge shaped clay bricks were custom made to build this unusual and unique conical lighthouse with balcony and lantern, it has never been rendered or painted. It is a distinct land mark on the peninsula.

It is designed to be resistant to high winds and earthquakes: in the twentieth century the area experienced numerous earthquakes.

Measuring 32 metres high, Troubridge Hill Lighthouse has a light range of 22 nautical miles and operates off mains electricity with a backup diesel alternator.

The brickwork construction system was innovative and earned an award from the South Australian Brick Association for an outstanding application of clay brickwork.

As it was intended for automatic operation the tower has no windows: it opened 1980 with the following technical details : -

Light source: Tungsten Halogen lamp arrays on revolving pedestal [due to high maintenance cost, these have been replaced with a more traditional rotating lens and electric lantern].

Power source: Mains supply with standby of diesel alternator and batteries

Character: 2 flashes every 15 seconds

Intensity: 257,000 candela

Range: 22 nautical miles

Tower height: 32 metres

Elevation: 62 metres above sea level.

I've still not got the X100 nailed yet, and as such haven't had many good photos.

This isn't perfect, but it's close enough for me to like it. I'm shooting in B&W a lot lately, but it's useful when there's never any daylight!

Tell me what you think.
