How to Light a Portrait with a Single LED

Previously we explored the idea of creating beautiful portraits with a single LED. In this post, Christina N Dickson will give 2 short tutorials on the LED portrait.

The LED for On-Location:

location.jpgThere will be times in your on location portraiture sessions when the available light is just too dim or weak to create an even portrait. Getting rid of shadows and adding catch-lights in this scenario is impossible unless you bring in another light source. An LED is a quick and non-imposing way of adding just enough light to create an artistic flair to your portrait.

1. Position your subject near the primary light source. In this case, window light is my main light and illuminates my subject. I turn my subject into the light until her skin is appears soft and luminous.

2. Add the LED. Rather than the LED acting as my main light, I use it to soften the transfer edges of the highlights and shadows along my subjects face. I am able to maintain shape and depth along her face without having harsh and distracting shadows.

3. Pull the LED away from your subject: If the LED is too close to your subject, the lighting will become flat – especially if we are using the LED as a fill light. Move the LED away from your subject as much as possible while still filling in and softening the shadows just a bit.

The LED for Studio:

1. Place your subject away from your backdrop. If the area behind your subject is dark, you’ll create a nice, black backdrop – no matter where you are. For this portrait. my subject is 5 feet in front of a dark hallway wall.

2. Get rid of all other light. To create a contrasty portrait, eliminate other light sources. Though you are using a single LED, the light will be more even and controlled without other competing light sources.

3. Position your LED. For a close up portrait with no other light sources, you will want to position the LED, 1 foot above and 2 feet away from your subject. This distance will enable you to cast light evenly along the face, and you won’t have to worry about distracting shadows falling under the eyes or the edge of the nose.

An LED can be purchased at Wal Mart or Amazon for $10 to $20 and is a pretty simple solution to acquiring an additional, easy to use light source for any off camera need.

LED Handrails Prevent Stairway Spills [LEDs]

In the not too distant future, LED handrails could make every stairwell seem like you are about to enter someplace indecent.

Despite what the aesthetics might suggest, something like this could be invaluable for commuters, people with poor eyesight, and fans of Tron. [Toxel via Designlaunches via Boing Boing Gadgets]

How Does IP Telephony Work

By Derek Rogers

IP tele­phony refers to the sys­tem of trans­mit­ting voice over a data net­work such as in broad­band Inter­net con­nec­tion. In com­par­i­son to the tra­di­tional ana­logue phone line, as an exten­sion to the prac­ti­cal Inter­net appli­ca­tions, it presents a cheaper and more acces­si­ble option to com­mu­ni­cat­ing with peo­ple from any part of the world.

With its call sound qual­ity that is com­pa­ra­ble and some­times bet­ter that that observed in ana­logue tele­phone con­ver­sa­tions, it presents a mod­ern and improved sys­tem for call man­age­ment hav­ing total flex­i­bil­ity in using and locat­ing phone num­bers. IP tele­phony, broad­band tele­phony or Voice over Inter­net Pro­to­col (VoIP) appli­ca­tions is oper­ated over the Inter­net through pack­ets of switched net­work.
