Unit #458, belonging to the Cranberry Township Police Department. This 2012 Chevy Caprice with a 6.0L V8. This is the last unit with the department with the old skin. Equipped with a Federal Signal Valor, single halogen spotlight, and a Pro Gard push bumper. This is their oldest unit, and is the next one to go.
This is an example of Tyndall-Rayleigh scattering using a quartz-halogen lamp instead of a high colour temperature LED. It shows more gradually graded Rayleigh spectrum colours with more extension into the red.

Beneath the sodium glow of the city lights, Jenny stood still as midnight... her silhouette a gleaming contradiction of softness and steel. The cream satin of her top caught every flicker from passing cars, tracing the curve of her confidence, while the leather jacket whispered tales of roads taken without asking permission.
She wasn’t just leaning on the motorcycle; she was part of it, forged in the same language of chrome and rebellion. The engine was silent now, but the air still pulsed with its memory. Somewhere behind her, music spilt from a shuttered café; somewhere ahead, the next streetlight blinked like a dare.
Tonight wasn’t planned. She hadn’t meant to chase the moon through alleyways or let the wind lift her thoughts like winged hair. As the breeze stirred the leaves overhead and the scent of petrol mingled with the scent of garden jasmine, Jenny smiled.
This wasn’t an escape. It was an arrival.
First photo from a small shoot, it's the only Lexus LFA in the world with halogens (same ones used on the endurance race car)
Strobist: 285 with umbrella camera left just to fill some shadows.
Walking down one of my favorite neighborhood streets, I noticed that the sidewalk was illuminated by some extremely bright headlights, coming from the next block. I realized that this powerful light, much like late afternoon sunlight, would create long shadows of walking by. I made about 25 shots, but chose this one because it was funny--the woman walking by had one short leg and one *very* long one.
The headlights weren't the regular ones, they had new-fangled halogen bulbs, whence the lovely silvery sheen on the slightly humid sidewalk. The temperature was just above freezing, so the snow had begun to melt. (My only problems getting around occurred at street crossings, where there were small piles of snow created by snow plows, as well as pools of slush.)

Shot under continuous light (two halogen light bulbs shooting through parchment), as you might have thought already. :-)
Phew, that camera is really not so good. And I dont like the 35 mm lens equivalent either. Tricks used:
1
This is a crop from a larger image to get the perspective and look-and-feel of a 60 mm lense

My old VistaLite halogen bicycle headlights from the 1990s. I put the Blackburn LED headlight I use today in the picture to show how far bicycle headlight technology has come. The separate VistaLite battery had to be recharged daily while I can go for weeks with the LED light, which seems even brighter, without a charge.

From the basement lab comes this 2.5" wide specimen.
On an aluminum tray, salt {~15 mL}, washing soda and sulfur were heated until the salt had melted leaving a mustard yellow mass that smelled strongly of hydrogen sulfide.
On the sample was then placed a solution of calcium chloride containing a drop of MnCl2 sol and a drop of PbCl2 ssol. which was absorbed into the yellow mass turning it whitish. The sample was then reheated until the salt had melted.

18 Watt Triple Output UV lamp from Polman Minerals - Way Too Cool UV lamps
Perfume flacon light setup: I tried quite a few things: Speedlight with snoot, led lamp, daylight lamps ..., and ended up with the simplest possible setup:
Small halogen desktop lamp, on the right side, on the floor, pointing to the lightblue backdrop (a curtain). Desktop with two black-painted boards and an acrylic plate upon them for the reflection. The camera is mounted on a tripod to allow the low ISO adjustment and long shutter times (some seconds). White balance was done with the Datacolor Spydercube.
Also quite helpful for perfectly sharp photos: Manual focus in 10x zoomed liveview mode.
Postprocessing in PS: Clean-up, masked sharpening, color shifting, crop, unobtrusive vignette.

And the way he said it, I believe he thought it was.
taken late last night.
our back drop (news print) got ripped a bunch of times.
and one of out halogen work lights burnt out so we only had one.
but besides that it was a great shoot.

Kitchen in Vegas high-rise. Little portable mini-halogens planted all over the place. This kitchen presented the apotheosis of a recurring challenge: how to effectively (and time-effectively) light a space when all the ambient light is warm, incandescent or halogen light. With all this contrast, a LOT of light is needed and those ceiling halogens just burn bright spots all over the image. Maybe I should bring a 500w halogen work lamp or two from Home Depot along. With some diffusion, it just might do the trick.
Any ideas?
This shot was named “First Smoke” because it is the first image taken in my new photography studio in my family room in the basement. It reminded me of the term “First Light” from astronomy(a).
It is appropriate that my studio is next to the bar. I shall measure the quality of my work as a function of the spirits that I might imbibe.
This is my first effort at shooting smoke. It is not great -- in fact, it isn’t even good. But, I know what I need to do to improve. I post this as a baseline.
That said, I kinda like how this turned out.

a. en.wikipedia.org/wiki/First_light_(astronomy)
Process:
Nikon D200, 300mm, 1/80, f/5.6, WB Tungsten, manual exposure, ISO 1600. Lighting: Harbor Freight 500W halogen worklight @ 24 inches left of smoke. Black background, barn doors around light. Adobe Photoshop include:
a. Unsharp mask to emphasize the noise (I liked it)
b. Color gradient fill layer using hard mask.
Observations:
1. I expected to have problems with lighting. A flash is mandatory if the smoke is to be in crisp focus. The best I could muster was 1/80sec at ISO 1600. It really didn’t freeze the smoke and, had I gone higher in ISO, the noise would have been worse.
2. The light must not hit the black background. I need better barn doors around the light.
3. The supply of Jack Daniels Single Barrel was running low and, therefore, the photo session was terminated before I could try a flash.

The word tulip, which earlier appeared in English in forms such as tulipa or tulipant, entered the language by way of French tulipe and its obsolete form tulipan or by way of Modern Latin tulīpa,
from Ottoman Turkish tülbend ("muslin" or "gauze"), and is ultimately derived from the Persian language dulband ("turban").
(The English word turban, first recorded in English in the 16th century, is a cognate.)

More experiments with a very simple DIY light table, if you can call it that :)
It's just a cardboard box which is white inside to bounce the light around, with a Tupperware container placed on top. No need to worry about a brand name being embossed into the container either, it doesnt show up with a reasonable amount of light shining through. The box although white inside, did have a sheet of whte paper laid in the bottom, just to ensure a nice even light.
Lighting was provided by a pretty standard halogen desk lamp, with I think a 15W bulb in it. Not normally the best of light sources for a nice even spread of light, but in this application with the light being bounced around inside the box, it gives a very even coverage as I hope this shot shows.
One thing to be careful of, these halogen lamps can get pretty hot, so be careful ;-)
Opal is a beautiful natural example of the production of brilliant colours without the presence of a chemical pigment or dye. The existence of a regular 3D array of nano-scale — about a third of the wavelength of the coloured light — scattering elements results in a play of colours arising from the interference of light waves with one another in a process called diffraction.
Using X-rays with wavelengths more than a thousand times smaller than visible light the Bragg father and son team (William and Lawrence) demonstrated the diffraction produced be simple atomic crystals in 1912. They won the Nobel Prize for physics in 1915 for using of this method to determine crystal structure. Since then, there have been 26 Nobel Prizes connected with the use of X-ray diffraction, including that in 1962 to Francis Crick, James Watson and Maurice Wilkins for discovering the structure and significance of DNA. This is a physical phenomenon with profound consequences for the understanding of our world, particularly perhaps for biology.
The so-called Bragg Law given in textbooks does not always include reference to the refractive index of the sample. This is probably because, at X-ray wavelengths, the relevant refractive indices are very close to one, the value for the vacuum. For visible light interacting with an opal however, the refractive index (RI, usually called 'n') of the opal matrix (silicon dioxide with some water, n ~ 1.45) is crucial in determining the colour that will reflect from a nano-structure with a particular physical spacing — typically between around 150 to 250 nanometers (nm, billionths of a metre).
While it had been supposed for a long time that opal colouration was due to some sort of optical interference/diffraction process — there is a nice description of this in the well-known book "Physical Optics" by R W Wood (1934) — it was a group of physicists in Australia in the 1960s/70s who were able to show that the nano-structure consisted of quite large (~1mm) regions that contained a regular, close-packed, 3D array of tiny, identically-sized silica spheres forming what has now come to be called a photonic crystal. As is described in an article in Scientific American in 1976 (see reference below), the diffraction is caused by scattering from the voids between the close-packed spheres which can contain water (see the comment below).
The silica/water opal matrix (essentially internally wet glass) is quite transparent and so the flecks of brilliant colour arising from these ~1mm highly ordered grains can be seen deep into the stone. One of the reasons for this post is that the silica is transparent not only in the visible but also deep into the UV. Why is that interesting?
It gives us the opportunity to see one of the characteristics of Bragg diffraction and that is, like a diffraction grating, the reflection consists of multiple orders: the 'm = 1, 2, 3,...' in the Bragg equation:
m lambda = 2 d sin (theta)
[lambda is the wavelength, d is the spacing of the diffracting centres, n is the refractive index and theta is the angle between the incident light beam and the plane of the diffracting centres on which the light is incident]
which, when combined with Snell's law of refraction becomes:
m lambda = 2 d n sin (theta)
With the eye, it is not really possible to see more than one order of diffraction since the second order will have to be in the blue at greater than 400nm which would mean that the primary, 1st order peak would be at around 800nm and that is beyond our visual capability.
Fortunately, my spectrometer covers a spectral range from 200 to 1100nm which is a large enough to see up to four orders (if I could find an opal that reflected at 1000nm!). I use a combination deuterium and quartz-halogen filament lamps to cover this large wavelength range. This plot shows the reflectance spectra of seven coloured flecks in an opalised sea shell from Australia that has an unusually transparent matrix. Five of these flecks show first, second and third orders while the remaining two show just a blue first order and a deep UV second order peak. The inset is an image of some of the reflecting coloured flecks.
I'm sure they must exist, but I have not seen any other spectra that show three spectral orders like this. Maybe I didn't Google hard enough?
The coloured '+' marks aligned along each spectrum show the predicted peaks of the second and third order reflections based on the measured wavelength of the first order peak. To do this, I need the refractive index of the opal matrix over the entire spectral range. I use the published values for amorphous silica which should be a pretty good approximation give-or-take a little water. Since the refractive index rises quite steeply into the UV, neglecting this effect would mean an error of a very noticeable 10nm or so for the position of the third order peak. This calculation also gives me to good accuracy the spacing between the scattering centres (d in the Bragg equation) of between 269nm for reddest spectrum (top) and 154nm for the bluest (bottom)
This inanimate natural material created a paradigm for understanding the huge variety of photonic structures that have now been discovered and studied in both animals and, increasingly, in plants. When looked at in detail, some of these life forms contain evolved structures of exquisite complexity which result in a range of properties that can be of immense value in technology and engineering.
