Digital Photography Tip - How To Photograph Christmas Lights

Christmas is coming and so is the urge for us who love digital photography to get out there in the burbs and photograph the beautiful Christmas lights. It's a beautiful time of year and when you are as passionate about digital photography as I am, then this is the time you whip that digital camera out.

Taking photos of Christmas lights with your digital camera can be a very disappointing experience for digital photography enthusiasts. Pictures of Christmas lights in digital photography are aimed at being crystal clear with beautifully bold colours and hopefully we can capture the delicate glow that radiates from the lights themselves.

But...Christmas lights don't always provide the ideal digital photography experience does it? J In fact, in digital photography, Christmas lights can turnout to be smudged dots of colour, like water over ink and way too dark. The first time I took a digital photography image of Christmas lights the flash went off accidentally causing a flattening out of my images not to mention the lovely colours disappearing and it ended up just being a digital photo of the neighbour's front lawn. Not to mention how it set the dog off barking!

So just what is the digital photography secret to getting crystal clear shots of our suburban Christmas lights?

Okay now I'm going to share a secret with you. The best way to get suburb results of sharp, colourful Christmas lights is to choose the house you are going to photograph. Depending on where you live and how fast you can run, you may need to tee it up with your neighboughs first and offer them the photo. The same rules apply with your Christmas tree.

Take your tripod with you. Take your digital camera off "auto" and take it off "auto flash".

Now try a method called bracketing. Set the aperture at a wide f stop, such as 2.8 or 3.5 for example. Then proceed to try some different settings. Set the shutter to 1/30 or higher. I'd recommend, if it's really dark in the street something around the one second, two seconds or three seconds shutter speed.

There is a groovy little trick you can also do for helping you learning faster, about what works in digital photography and what doesn't. That's recording and documenting your digital photography experience. I usually take a note pad with me and write down the number photo and the f stop and shutter speed so when I look at the photos I know which digital photo has worked and what has not.

But in the dark it's very hard to write down anything so you can do what I sued to do, and that is record on Mp3 what your settings you had on what photo. For example you can record yourself saying "picture one, f stop 2.8, shutter speed 2 seconds." Then again as you have tried another setting "picture seven, f stop 22, shutter speed 1 minute."

These are just examples but they really work. Don't forget the basics with your night time photography such as wide aperture and slow shutter speed and the necessity of a tripod.

If you are in a moving vehicle for example and you are taking shots of Christmas lights from a bus or car, then you can always use the maximum aperture and a smaller shutter speed. For example f stop 1.4 and a shutter of 1/350 or higher.

And don't forget if you do have the time to set up a tripod and try the bracketing technique (ideal) also remember if you have the shutter open for a while the light can bounce off other objects such as windows and roofs. If you get too much reflective light, simply reduce the time the shutter is open.

Good luck and may you have a beautiful Christmas!

Happy Shooting,

Amy Renfrey

LED Lights - Christmas is Not All LED Lighting is For

During the last five years, LED (light emitting diode) lights have become more and more popular, as well as more affordable. While the technology that was first discovered in the early 1900s has already been used for several decades in commercial applications such as billboards, traffic lights, and exit signs, it has now made its way into the home in a whole lot more than just the display on your electric alarm clock.

The Many Uses and Types of LED Lights

Lamps Christmas

Also referred to as solid-state lighting, LEDs use several types of inorganic semiconductor materials to create light that is visible to the eye. These materials, which vary depending on the color needed, are encased in a highly durable plastic, allowing the lights to be used in many different practical applications in everything from a simple calculator to the most advanced of electronics.

Some of the other many items utilizing LED technology include indicator lights on automobiles, motorcycles, bicycles, and boats, traffic lights, exit signs, strips of emergency landing lights at airports, as well as in lanterns and flashlights. Places like Las Vegas would look totally different, not to mention mostly dark, without the use of light emitting diodes. Even some museums are now turning to LED lights as the amount of ultraviolet (UV) rays that are emitted in comparison to the heat given off by other types of lighting is negligible and keeps the valuable artwork and delicate artifacts safe from heat damage.

Extremely useful applications in the world of medicine, including pulse oximeters that measure the amount of oxygen saturation within the blood, also use LED lights in their displays, as well as in a process for sterilizing water and in a special type of phototherapy used for treating acne. Computers and wireless, optical mice also use light emitting diodes, along with a host of sporting good equipment, toys, flashlights, cell phones, remote controls, and video games.

For the sheer purpose of lighting, LEDs are also used in light bulbs, grow lights for gardening, street lights, architectural lights, stage lighting, large video displays, and emergency lights for police cars, fire trucks, and ambulances.

As technology continues to advance, it's expected that LED lights will soon be used all over the inside and the outside of the home, giving people the option of changing both the color and intensity of their lighting with the flip of a switch, creating a variety of special effects and moods.

Basically, there are three different types of LED lights and they include alphanumeric, illumination, and miniature. Each of these types also come in a variety of shapes and sizes as the plastic that holds the diodes is able to shaped into many different forms. Clusters of LEDs can be placed into straight lines, as they are in clocks or signs, or in an array of geometric patterns, both uniform and irregular.

Some of the many advantages of LED lights include:

- Most all LED lights will gradually dim over time, as opposed to abruptly "burning out" the way other light bulbs do. The average lifespan of most types of LED lights is an astounding 35,000 to 50,000 hours of use, as opposed to an average of one to two thousand hours of light from incandescent bulbs and 30,000 for fluorescent tube lighting.

- There is no mercury or hazardous materials within LED lights, enabling them to be discarded right along with the regular garbage instead of needing to be disposed of carefully the way fluorescent bulbs must be.

- Since the casing used to house the materials to create light emitting diodes is made of an extremely durable epoxy based plastic, they're virtually indestructible and are able to withstand use in harsh outdoor conditions as well.

Some of the known disadvantages of LED lights include:

- Light emitting diodes are definitely more expensive, at least initially, on a price per lumen basis in comparison to traditional forms of lighting.

- The overall performance of light emitting diodes will mostly depend on the ambient temperature of the environment, or the room temperature. Adequately heat-sinking the diodes is needed if the application will be in regular contact with high temperatures.

- LEDs aren't capable of producing collimated beams of light, which are light rays that are parallel with one another such as those used in lasers, without the addition of a collimation lens.
