Painting with Light

 

What You'll Need

Instructions

Take the approach of using the air in front of you as a canvas and a flashlight as a drawing tool. Set up a DSLR camera in a dark environment uncontaminated by extraneous light. Place the camera on a sturdy tripod to eliminate movement. Draw with a small bright flashlight by shining it directly at the camera while moving it in front of the lens. Try some gesture drawings. Use flowing arm movements to record gestures suggesting outlines of people or objects.

Experiment with different camera settings to get the right look. Use at least a 20-second exposure time. Step down your aperture until the picture looks right. Allow a minute or more for more complex line drawings. Shoot against an uncluttered or artfully arranged backdrop so the light painting doesn't have to compete with a busy background. Take several pictures to judge the correct exposure. Adjust your exposure time up or down depending on how bright you want the light to appear.

Use a digital camera to be able to see and correct the results of your technique. Make close-up light paintings or zoom out for larger compositions. Run around within range of the camera, composing with your flashlight. Don't hold the light in the same spot too long, or it will show up too bright in the picture.

Make linear light drawings by using single lines of light to define outlines. Use overlapping strokes of the flashlight for shaded or smeared painterly affects. Try using fluid arm motions as you paint with light. Write messages in the air, or place color filters over the flashlight to punch up your pictures with bright, neon-like hues. Tape colored paper or gels over the light's lens for different color affects.

Use the illumination technique for an alternative approach to painting with light by shooting outdoors when there's little or no natural ambient light. Illuminate areas and objects of your scene with a wide-beam flashlight while the shutter is open. Shine the flashlight on different objects for a few seconds. Give each object the same illumination time. Work for a surrealistic affect with this method.

 

Product like shot - In a closed (dark) room place your product on a table and paint it's contour. You can use several colors to make a strong effect or to draw different (even imaginary) parts of your object.

Location shot - find a location with some ambient light. Find an object that is less "hit" by that light. now you can use the ambient light to capture the background, while painting the object with light. You will get a nice effect - with some surreal foreground and a "normal" background. Also the white balance will be different on ambient and painted - another cool side affect.

Environmental Graffiti - If you are shooting a wall (or even on thin air...), you can scribe on the wall. Make funny graffiti; Write huge love notes; Make a political statement - there will be no trace left other then the one on your memory card.

Exposure Time

This is difficult to judge, so needs some experimentation. A good starting point is to carry out a trial run, where you start behind your camera and then run around your scene, illuminating the objects as you go. Time how long it takes you to do this, and then use that as a starting point for your exposure time.

If you have a lot of light painting to do, you may find that the illuminated areas come out too faint to make an impact. To get around this you'll need to split your scene up into logical areas and take multiple shorter exposures. These can later be combined in a software package like Photoshop. To combine your exposures, stack them on top of each other in separate layers and select "Screen" as the blend mode for each.

Painting with Light - "Illumination" Technique

This technique works well when there's very little natural light available, and involves using a torch with a wide beam to illuminate large areas of your scene at a time.

Open your shutter and then run around your scene, stopping to shine your torch on the objects or areas that you want illuminated for a few seconds at a time. You might need to take a few exposures to help you judge exactly how long to shine the torch for, but try to give each object in the scene roughly the same illumination time so that they all show up well.

Also remember to stay out of the line of sight of the camera when you've got the torch on or you'll leave a silhouette in front of the object you're illuminating.

Painting with Light - "Light Streaks" Technique

For this type of painting with light you'll need a small bulb such as an LED torch or exposed torch bulb.

This time, rather than shining your light at objects, you want to keep it angled so that it is always visible by the camera. Keep it moving through your scene and be careful with the speed you move at because that will affect the light's brightness in the final image.

You can either run randomly through your scene, weaving an interesting trail as you go, or you can use the light to trace the outline of an object in your scene, which produces a really interesting 'neon sign' type effect.

Experimentation is the Key

Whichever painting with light technique you try, it's very hard to nail settings such as exposure time at the first attempt, so be prepared to experiment. Digital cameras have made this exceptionally easy because you can review your results within seconds of taking the photo.

As well as experimenting with settings, why not play around in other ways, for example:
