	Television Production: The Fill, Back and Background Lights
		The key light by itself — whether it's the sun in a clear sky or a focused quartz light in the studio — produces distracting shadows.
		If the back light is too low, it will be picked up by the camera in wide shots; if it's too high it will spill over the top of the subject's head, lighting up the tip of the nose, creating "the Rudolph effect," after a well-known reindeer.
		First, back lights are often placed closer to the subject than the key light, and, second, with subjects confined to a limited area like a chair, the beams of most Fresnel lights can easily be "pinned down" (focused into a narrower beam) to intensify the beam.

	G4 - Feature - 3D Animation Tip: Three-Point Lighting
		Back light -- The job of the back light is to bring out the silhouette of the subject.
		The back light helps to separate the subject from the background; this directs the viewer's eye towards the subject.
		The back light does not usually simulate "real" light and should only be adjusted until it is pleasing to the eye.

	Back Light In 180 Degree Dolly
		Hey guys...I'm about to shoot a music video, 16mm (7217), one of the main playback of the band is a white scenario with a red tree in the middle and the 4 members of the band also wearing white clothes with some red details...the camera would be in a 180 half circle dolly.
		What do I do with the back light (which I would like to have in the front angle) when the camera is on one side and it has been changed to be a key light overexposed?
		Typically there is a close up (med shot etc.) of the whole song on the lead singer and you may wish to consider the lighting approach on this and then let this drive the look for the wide coverage.

	PhysOrgForum Science, Physics and Technology Discussion Forums -> How does light speed back up on leaving a medium?
		I think we fail to appreciate how thin light is. It is largely the crystaline lattices of the silicone in glass and the self-arrangement of water molecules that allow light to pass through them at all at useable thicknesses.
		Light accelerating is the evidence of its propulsion.
		I am guessing that the light slows down because the light 'particles' get fatter as they encounter and travel through the medium and as a result they appear shorter as well because some of the light's speed is translated into getting fatter.

	[back light module] patent invention (Site not responding. Last check: 2007-10-26)
		A back light module comprising a frame, a reflective plate, at least a light source, a caved transparent plate, a diffusion plate and several optical films is provided.
		With the caved transparent plate disposed inside the back light module, heat is prevented from passing from the back light module into a liquid crystal display panel.
		Because the transfer of heat to the liquid crystal panel from the light source is unlikely to be uniform, the liquid crystal layer within the liquid crystal panel is subjected to different degrees of heating.

	Three Point Lighting Tutorial
		Your Key Light represents the dominant light source, such as the sun, a window, or ceiling light - although the Key does not have to be positioned exactly at this source.
		The key light is brighter than any other light illuminating the front of the subject, is the main shadow-caster in your scene, and casts the darkest shadows.
		Your "one light" scene (with just the key light) should have a nice balance and contrast between light and dark, and shading that uses all of the grays in between.

	Canadian Survey Sheds New Light on Back Pain
		Participants were asked a series of questions about their own experiences with back pain (frequency, severity, possible causes, etc.), along with the methods used to treat the pain, and how satisfied they were with treatment.
		When a person experienced back pain, he or she was more likely to reach for some type of medication before seeing a doctor of chiropractic.
		Of the back pain sufferers who did nothing to address the condition, over two-thirds did so because they either thought the pain would go away, thought the pain wasn't that severe, or disliked or didn't trust drugs.

	Back light module with birefringent crystal assemblies patent invention (Site not responding. Last check: 2007-10-26)
		A back light module (100) includes a light guide plate (130), a number of light sources (110) at one side of the light guide plate, and a number of birefringent crystal assemblies (120) respectively located between the light sources and the side of the light guide plate.
		Light emitted from the LEDs 21 enters the side of the light guide plate 22 and eventually emits uniformly from a top surface of the light guide plate 22.
		The back light module 20 does not provide uniform brightness over an entire area of the associated liquid crystal display panel.

		Our scan backs gather the information for the image in one continuous scan as the light is collected by three, individually filtered rows of pixels – this is called a tri-linear CCD.
		If you are using the scan back for product work, you will not have the moiré issues and noise problems that most of the other digital cameras experience.
		The Better Light backs provide extremely sharp focus, wide dynamic range, total control of your image tone range, extraordinary adjustment of density (exposure) in less than 1/10th f-stop steps.

	Hydrogen Detected From Three Billion Light Years Back
		For the first time, astrophysicists have detected hydrogen from a galaxy beyond our local universe, allowing us to stare back in time and witness the evolution of the universe.

		New radio telescopes such as the Square Kilometre Array (SKA) that Australia is bidding to have built here will be able to look back at over 90 per cent of the age of the universe.

		Eventually you're going to have to back up, and as we all know, most stock back-up lights don't even come close to generating enough light to adequately illuminate sheetmetal-bending trees and rocks.
		Since the IPF light is designed to offer the option of illuminating when the back-up lights are on, you'll need to tap into the stock back-up lamp wire at one of the rear lights.
		The IPF light features a waterproof connector in the wiring near the light, which allows for simple installation and removal of the light to access the spare tire.
