Kinetic Light Painting vs Light Painting

16 Jul

The post Kinetic Light Painting vs Light Painting appeared first on Digital Photography School. It was authored by Simon Bond.

One of the most exciting techniques in photography is light painting. This is an area of photography that can be carried out in several ways. In this article, you’ll learn about both kinetic light painting and regular light painting, what the difference is, and the different techniques employed by these styles. So engage the hyperdrive and put your creativity up to light speed today!

What is light painting?

This photo has used camera rotation to add more interest to this photo of some skyscrapers.

Light painting happens when a source of light moves across the frame of a camera during a long exposure. You’ll almost certainly need a tripod to practice good light painting photography, though there are some abstract light paintings you can do handheld.

The exposure time is typically between two and thirty seconds in length, but some photos expose for much longer and use the bulb function.

The simplest light painting you can do is to use a torch to spell your name. The complexity of light paintings can then go up as different tools are used to produce increasingly complex and beautiful light patterns. Light painting has a cousin though, and that’s kinetic light painting. This works slightly differently.

How does kinetic light painting differ?

With regular light painting, your camera will stay completely still, while a light source in front of the camera gets moved. However, with kinetic light painting, the camera or elements of the camera are moved, while the light source stays completely still. The movement of the camera is the reason this is called kinetic light painting.

The two main methods available to move the camera are moving the lens or moving the camera body.

Light painting techniques

Let’s look at the different light painting techniques you can try. These almost certainly need a tripod to carry out correctly.

Light writing

This is often considered the simplest of the light painting techniques. A regular torch is all that’s needed, along with a camera and tripod. You don’t have to use a torch; a sparkler or the glowing embers at the end of a piece of wood work too.

You now need to write your word, or perhaps a shape in the sky. Make sure you use a long enough exposure to complete the light writing you’re going to attempt. Also note that you’ll need to write as a mirror image, so when you write the “S” or any other letter, make sure it’s backward.

In this photo, embers were used to spell the country name, India.

Lighting an object

Instead of aiming your light source at the camera, you’re going to aim it away from the camera so it can light up an object. It’s likely you’ll also be stood behind the camera when you’re lighting up an object, but in some cases, you will need to stand in front of the camera. When stood in front of the camera, ensure no part of the light source shines towards the camera; it’s likely to ruin the photo.

Now stroke over the object you wish to paint – literally – as if your light source was a brush. Ensure you get an even distribution of light. You can experiment with sidelight if you wish to bring out more textures in your object. This technique will likely involve longer exposures of ten or more seconds.

Light orbs

These are created by attaching a light source to a piece of string and then spinning it.

The typical light you’ll use for this is a torch, LED light, or fairy lights bunched together. In addition to spinning the light source, you’ll need to rotate around the central point of rotation. Imagine your hand is the central point. You need to orbit your hand while spinning the light source.

It can be tricky to create the perfect light orb, so you’ll need to practice this technique.

Light orbs look great in photos, they take a bit of practice to get right though.

Light Spirograph

This is similar to creating a light orb, and once again you’ll be placing a light source on the end of some string. This technique is carried out indoors. The string is attached to a hook, with the hook attached to the ceiling.

Place the camera directly below and in line with the light source. Turn the lights in the room out, and ensure no outside light is shining into the room from a window.

Now set the camera to expose for 10 or 15 seconds. Pull the string back, and allow the light source to spin in an elliptical shape. Now check your result, and repeat if needed.

This shows interesting patterns from a light Spirograph.

Created your own light trails

This is the area of light painting that’s perhaps the most fun. There are lots of tools out there you can use. Anything that lights up will work. This is where the patterns can get more complex, but the key to good light painting is to keep it simple.

Have a look at some of these tools, and see which one appeals to you.

  • Lightsaber – These don’t emit a strong point of light, but you will be able to use them to create smooth panels of light. As the light isn’t strong, it’s likely you’ll see the scene behind the light painted area, sometimes a desirable trait.
  • Glow stick – These work in a similar way to a lightsaber, and the amount of light they produce are low so you’ll need to use this in a dark place.
  • Wire wool – Pack some fine wire wool into a whisk, attached to some string. Now set the wire wool on fire and spin! Sparks will fly, but take care not to cause a fire or burn yourself.
  • Fairy lights – Use battery operated fairy lights for light painting. Use them to create a light orb, or attach them to a stick and make your own D.I.Y. light stick.
  • LED light stick – This is your all-in-one light painting mega tool. It’s expensive but you’ll be able to produce more or less any light painting effect. And you only need one device to do it.
  • Hula-hoop light – These are a little like the LED light sticks. Only instead of a stick, the programmable lights are now in a hula-hoop. They’re often used by dancers but also work very well in photography as well.

In this photo, you can see light patterns created using an LED light stick.

Light trails

You don’t always need to make your own light trails. There are plenty of opportunities to photograph moving lights created by others! You have no control over how these lights move, however, you can choose places with predictable light trails, and you can choose where to stand.

The following are examples of where you can photograph light trails.

  • Traffic trails – The most obvious and easiest light trail is formed by moving vehicles. It’s nice and predictable as well, as everything will move along a road network.
  • Boat lights – Boat light trails are a little more difficult to photograph. Choose a location with regular boat traffic, perhaps a river taxi area. Finally, be prepared to take several exposures, and merge them together in Photoshop. Boats move a lot slower than cars, so they won’t move through your frame in a single 30-second exposure.
  • Stars – Use a series of 30-second exposures and stack them together to form one photo. It’s best to aim at the north star or southern crux, this will lead to stars rotating across the sky.

Car light trails are one of the easiest and most popular form of light painting.

Kinetic light painting techniques

While regular light painting often needs additional equipment, kinetic light painting only needs a camera, lens, and a tripod. The lens you’ll need is a factor; you’ll learn about that in a moment.

The following are the different ways you can move your camera to create light paintings.

Camera zoom

This is a technique that uses the movement of a zoom lens to produce a light painting. The idea is that you use a long exposure and that during the exposure, you move the focal length of the lens. With nighttime light painting, it’s best to zoom out, starting at the lenses longest focal length. The best lens to use here is a superzoom 18-300mm lens since this gives you more choice over the focal distance range you’ll use for the photo. If this lens isn’t available a wide or mid-range zoom lens is the next best option.

  • Abstract – To create this type of photo, zoom in on some lights. Now expose for two or three seconds, and continuously zoom out during the exposure.
  • Two-step – With this approach, you’re going to combine the abstract zoom burst described above with a regular photo. To do this, first pre-compose your photo at the final focal length you’ll finish your photo at, and focus in manual mode. Now zoom into the central area you’ll zoom out from. Take a 30-second exposure. The first 2-3 seconds will be the zoom burst, and the remaining exposure time will be the regular exposure.
  • Flash – You can combine zoom with flash photography as well. The flash will freeze your subject, usually a person, and then you can zoom out for the remaining part of the exposure. Use a shorter one-second exposure for this method.

This photo has used a zoom burst to create light patterns. The photo is cropped in so that the central zoom area is off-center.

Camera rotation

Another type of kinetic light painting is camera rotation.

This works best when rotating from the head of a tripod, and for that reason, you’ll often be using a worm’s eye perspective for this photo. Once again, you can take this as an abstract, two-step or you can combine it with flash. This type of photo really needs a wide-angle lens. You might even experiment with a fisheye lens.

  • Abstract – Look for a light source that’s tall and vertical, preferably lit from top to bottom. A skyscraper or tower is ideal. Use a two to three-second exposure and continuously rotate the head of the tripod during the exposure.
  • Two step – Once again, you’re going to combine the abstract photo described above with a regular nighttime long exposure. This time when pre-composing, make sure you make a note of the angles of degree on your tripod head that you begin the exposure at. Now take a 30-second exposure, once again rotating the camera head during the exposure. However, this time, when you reach the number on your tripod head that you started the exposure, it’s time to lock the camera in position for the remaining exposure time.
  • Flash – Use a one-second exposure time, and aim the flash at your subject. Now smoothly rotate the camera around the central point of your photo. This must be done handheld, making this a tricky technique to get right.

You can use flash in combination with a zoom burst, as seen in this photo.

Random camera movement

The two above techniques use controlled movements of the camera for light painting. The moving part can only move in one way, so you get smooth lines through the photo.

It’s also possible to use random movements of the camera to produce light paintings as well. You can even do this using the two-step approach used for zoom and rotation.

The abstract approach is easiest. Use some fairy lights and randomly move your camera in front of them. To use the two-step approach, you’ll need to move the camera around in some random motion. Once finished, lock the camera in position for the remaining exposure time.

Other movements can be used for kinetic light painting. The risk is the photo becomes too busy.

Conclusion

There are many forms of creativity in photography, especially at night. Light painting is a great technique to experiment with, and kinetic light painting is an interesting sub-genre of this that’s really worth exploring.

Have you tried light painting before? How about kinetic light painting?

Here at digital photography school, we’d love you to share your experiences of these techniques, together with any photos you have taken, or will take having read this article.

Living Light: 11 Transforming Kinetic & Illuminated Art Installations

22 Jun

[ By SA Rogers in Art & Installation & Sound. ]

Rippling, unfolding, slithering and glowing like bioluminescent creatures, these kinetic and illuminated works of art are mesmerizing to watch. We can’t help being fascinated by the combination of light and motion, especially when it’s integrated into clothing, responds to our gaze or voices, or is engineered into monumental interactive installations of laser beams for our slack-jawed amusement.

Sound Activated Clothing by Ying Gao

‘Incertitudes’ and ‘(NO)Where (NOW)here’ by fashion designer Ying Gao are two series of unusual reactive garments – the former covered in rippling dressmaker pins, and the latter moving like a living creature while glowing eerily in the dark. The photo luminescent thread works with eye tracking technology to activate movement by the gaze of spectators, while the pins respond to spectators’ voices.

Experimental Kinetic Glass Installations by LASVIT

Czech lighting company LASVIT presents a series of experimental kinetic glass installations during Milan Design Week, creating immersive illuminated environments that move and shift in synchronized rhythms.

La Vie en Rose by Atelier Öi & USM

A company called USM produces a network of industrial components known as USM Haller Systems that offer infinite reuse and reconfiguration possibilities. For Designer’s Saturday 2014 in Switzerland, the company commissioned Atelier Öi to use these parts as a base for a kinetic art installation expressing these possibilities. ‘La Vie en Rose’ is the result.

CL:OC Installation by GROSSE 8

Hanging flurorescent tubes powered by twenty-eight motors hang in the air, constantly rearranging themselves to display the time in digital numbers. Created by German design collective GROSSE 8, the sculpture debuted at Interior Design Week Cologne.

Big Dipper: Helical Kinetic Sculpture by Michael Candy

Looming in the air like some kind of monstrous mechanical spider, BIG DIPPER by Michael Candy is suspended within an old warehouse in India, just waiting to scare the pants off a passerby. It features 18 fluorescent tubes sticking out of a plywood and metal body.

METALmorphosis: Kinetic Sculpture by Controversial Czech Artist

21 May

[ By SA Rogers in Art & Sculpture & Craft. ]

david cerny 1

A giant metallic head splits into segments and rotates in a ‘metamorphosis’ worthy of its subject, author Franz Kafka. All 42 of its layers spin independently, catching the sunlight on their reflective stainless steel edges, magnifying the strange transformation as the head briefly blurs into something more abstract and then comes together again. The 45-ton sculpture was installed in a Prague plaza in 2014, visualizing the inner workings of a psyche the sculptor may identify with, himself. It’s perhaps the tamest and least controversial piece Czech artist David Cerný has ever put out for public consumption.

Entitled ‘K’, the sculpture has a nearly-identical twin called METALMORPHOSIS in Technology Plaza in Charlotte, North Carolina, which even had its own live webcam feed for a while so anyone in the world could watch passersby interact with it at any given moment. The Charlotte version is not based on Kafka, and sits in the center of a fountain, occasionally spitting water. Its mirrored exterior almost makes it seem like an optical illusion in certain lights, like some kind of apparition made of the sky itself.

Born in Prague, David ?erný first gained notoriety in 1991 when he took it upon himself to paint a Soviet tank serving as a war memorial in his home city bright pink. A number of his statues feature grown men peeing, and the literally masturbatory ‘Nation for Itself Forever’ had to be perched on the roof of the National Theater to keep it from being defaced.

Crawling babies with bizarrely punched-in faces scale the Czech Republic’s highest tower and wander blindly around parks, while the nation’s most revered saint, St. Wenceslas, is depicted riding a dead horse. A permanent exhibition at FUTURA gallery Prague features ladders leading up to two white posteriors; climb up and stick your head inside to view a video of two Czech politicians spoon-feeding each other to ‘We Are the Champions.” Czech out a tour of the irreverent sculptor’s works in Prague if you’re ever in the city to see them all.

Metallic Life Forms: Kinetic Sculptures Undulate in the Wind

05 May

[ By Steph in Art & Sculpture & Craft. ]

anthony howe kinetic sculpture 3

There’s something alien about the way these metallic structures move, a fluidity that makes them seem as if they’re alive. Each one transforms so completely as it spins, the results almost seem like optical illusions. It’s really all a play of light and shadow on cleverly designed kinetic sculptures, which are engineered to spin effortlessly whether the winds are barely blowing or gusting with extreme force.

Working through many a night in his remote workshop on Orcas Island, Washington, Howe refuses commissioned orders, working only from his personal creative inspiration. Hundreds of his sculptures have sold to private and public collections around the world, including large-scale urban works in several cities.

“Kinetic sculpture resides at the intersection of artistic inspiration and mechanical complexity. The making of one of my nieces relies on creative expression, metal fabrication, and a slow design process in equal parts. It aims to alter one’s experience of time and space when witnessed. It also needs to weather winds of 90mph and still move in a one mile per hour breeze and do so for hundreds of years.”

Architecturally Alive: 16 Transforming Kinetic Buildings

14 Jul

[ By Steph in Architecture & Cities & Urbanism. ]

moving architecture kundig 2

Will the cities of tomorrow be filled with intelligent kinetic architecture that moves and transforms of its own accord, as if it has a life of its own? The designers of these 16 structures seem to think so, whether they’re making use of ancient pulley-powered systems or engineering remarkably responsive auto-adaptations to change the look of a structure, shield it from the sun, or make it seem like a living creature in a bid to foster deeper connections between humans and architecture.

Adaptable Snow Cone Lifeguard Station

Modeled on a pine cone, this lifeguard post by RAW Design, Ferris + Associates and Curio adapts to weather conditions on Toronto beaches. The white ‘petals’ can move to either offer shade during the hot summer months or to collect snow in the winter for extra insulation. The petals can also be retracted on one side and closed on the other to guard against heavy winds but still let sunshine in. It was fabricated in three weeks and then re-assembled on-site within 6 hours.

Penumbra Adaptive Window Shading System

The Penumbra system by Tyler Short is “designed to offer a kinetic and mechanical solution to a problem that would otherwise be nearly impossible to solve with static architectural components: providing shading across a building facade for both low evening sun and high afternoon sun conditions.” The various kinetic elements of the shade system can shift in different ways to deflect light as needed.

A home with a roof that opens vertically, an art gallery with a hoist-and-pulley facade and a ‘virtually indestructible’ cabin with operable steel panels are among the kinetic projects by Tom Kundig of the firm Olson Kundig. The architect says early exposure to mining, logging and farming industries led to a lifelong fascination with machinery, which he has integrated into all sorts of architectural projects. The idea is to move something large using very little energy, encouraging user participation in the transformation of the space in concert with geometry and physics.

Kinetic Desk Rises to Nudge You Into a Standing Position

03 Feb

[ By Steph in Design & Furniture & Decor. ]

kinetic desk 1

Ready or not, it’s time to stand up when this kinetic desk starts to rise on its own, ensuring that you don’t spend too much time in an unhealthy seated position as you work. Studies have shown that parking ourselves in chairs for eight hours or more per day can lead to organ damage, foggy brain, a strained neck, muscle degeneration and other negative effects. Experts recommend alternating between sitting and standing – and now there’s a high-tech desk that will help you do just that.

kinetic desk 2

The Stir Kinetic Desk gently raises and lowers itself at pre-set intervals, to custom heights of your choice. A built-in touch screen on the desk surface enables you to check your daily stats, telling you how long you’ve spent in each position and when your next adjustment should be.

kinetic desk 3

kinetic desk 4

You just double-tap the home screen to move the desk to its next position when desired, using a slider to create your desk height presets. A function called ‘Whisperbreath’ creates a gentle one-inch rise and fall of the desk surface to signal you that it’s time to stand up so you don’t have to stop what you’re doing.

kinetic desk 5

The creator calls it a “non-wearable wearable,” i.e. a fitness-tracking gadget that works in a similar way to smart watches and Fitbits. You can also synch other fitness tech to track how many calories you burn while standing. The cost of “the world’s most advanced desk” clocks in at $ 2,990.

Kinetic Facade: Awesome Adaptive Window Shading System

17 Mar

[ By WebUrbanist in Gadgets & Geekery & Technology. ]

animated-window-system

Buildings are forever in tension, being static objects in a dynamic world – light conditions in particular shift predictably yet variably throughout the day, week, season and year, in turn demanding an adaptive response.

dynamic facade shading

Thus the Penumbra system by Tyler Short, designed to offer a kinetic and mechanical solution to a problem that would otherwise be nearly impossible to solve with static architectural components: providing shading across a building facade for both low evening sun and high afternoon sun conditions.”

adaptive facade interior gears

The constituent parts can shift side to side while in their vertical orientation, then turn on a proverbial dime to form a horizontal shading solution, all creating a way to deflect (and let in) light while maintaining control over views.

kinetic shade facade system

More from the designer: “Our solution was a series of vertical shading louvers, that can independently pivot to maximize solar protection, and when the sun reaches an altitude in which vertical louvers would be ineffective, completely rotate upwards to act as a horizontal shading element and light shelf. All of the mechanical components and gear ratios were fully resolved, and the result is a hand or computer-operated system that creates a beautiful undulating form across the facade.”

Touch to Open: Kinetic Doors Unfold Like Life-Sized Origami

21 Feb

[ By WebUrbanist in Design & Furniture & Decor. ]

flip-animated-kinetic-doorw

Made of rubber, metal, glass and wood, these dynamic flip panel doors tackle perhaps the world’s original architectural invention in a series in a fresh, new and interactive fashion.

flip-panel-door-loop

Each member of the Evolution Door set by Austrian artist, designer and builder Klemens Torggler involves a multi-panel contraption the flips open and re-closes in a fantastic feat of kinetic motion.

flip-steel-door-design

The steel version of the door is particularly ingenious as its space-saving method of action. Like its sliding cousins, it avoids the in-and-out motions of a typical doorway to minimize the space you need to set aside in front of or behind it.

klemens toggler glass door

The glass design uses a minimalist framework of structural supports, all of which then disappears entirely into a secret wall space hidden alongside it.

With steel and glass variants in particular, though, viewers are sure to wonder how one avoids getting a finger pinched if they are not paying full attention,  hence this short video regarding benefits of the softest member of the Evolution family.

flip panel door design

Aside from the finger-friendly end result, there is something brilliant in the common approach of these works: each bypasses all positions outside of the binary ones – these doors are either opened or closed between uses, never resting anywhere in between.
