The ‚dedolight Lightstream’ should not be
regarded as a general lighting tutorial. Here we will
mainly concentrate on various aspects of reflected
We are well aware that light and lighting is a vast
subject with an incredible variety of aspects about
the character of light. There is unnoticeable natural
light, there is unnoticeably created light.
There is unnoticeable light with subtle accents,
guiding the attention.
Such lighting can serve as an element of image
Then we have the many characters of noticeable
lighting, as gentle as the autumn light in Paris,
which makes women all look like they have been
painted by Renoir.
All the way from this wonderful, gentle, amiable
light character that makes people glow, to the
dramatic light characters as you find them in
Caravaggio and El Greco.
Yes, we all know that lighting and the art of lighting
should not be regarded as a value on its own. The
most important is the story that we need to tell and
what style we choose. And from this vast field of
many subjects, here we are mainly talking about
aspects of reflected light in its purity, and mixed
with other lighting instruments and characters. Here
we want to talk about the tools, the physics and
practices; and hopefully we will be able to give
some valuable explanations and hints.
Everyone of us has used reflected light in our profession, be it cinematography or other approaches to image creation.
Reflected light can provide a multitude of characters, many of which are not achievable by any method of direct lighting.
Hard reflection can have a very special character. Sometimes, this could be interpreted as simply redirecting the light, where, at the same time we are creating a virtual light source at considerable distance from the object being lit.
Hard reflected light very often is also polarized light, providing a different surface texture, different impressions. Gentler reflections can show a great variety of spreading of the reflected light. In all of these, it is important to consider the area, from which the light is being reflected. Small area reflections may still provide harder light and harder shadows. Larger reflective areas will produce gentler transitions between light and shadow.
Reflective surfaces vary in the degree of reflectivity: All together reflective surfaces provide a rich choice and an incredible variety of influencers for the character of light used.
Colored reflective surfaces may add qualities of their own in an incredible variety from the shiny gold reflector, used to produce warm and pleasant skin tones, to warm-colored wooden surfaces, adding subtle hues of warmth to the image and skin tones.
In combination with narrow-beam light fixtures or parallel beam light fixtures it is possible to transport tremendous intensity of light over a considerable distance.
Combining such light fixtures with the use of reflective surfaces can be used to redirect light, but can also be used in many different ways, and can add to an incredible variety of creative tools and practices.
To light interiors of a high building, beam projectors are placed on street level, shining straight up. Large, hard reflectors placed overhead of the windows redirect the incoming light and simulate incoming natural daylight. Because we create a virtual light source way up and high in the sky.More
dedolight Lightstream and Eflect are the names of our new lighting tools and practices. The new tools are parallel beam light fixtures and highly developed optical systems which function with dedolight focusing lights. The tools also include a selection of reflectors with a selection of very efficient reflector surfaces, with a variety of functions, and are available in different sizes.More
Reflector surfaces. These are reflectors for the application and use in dedolight Lightstream Drama and dedolight Lightstream TV. The high efficiency of these reflectors within this system derives from reflective values, where approx. 95-98% of the light can be effectively reflected. At the moment we use four different reflector types, each featuring a different reflecting surfaces.More
Although Lightstream technology and other practices of lighting with reflected light, like CRLS, the system used for major drama productions, originally by Christian Berger and Jakob Ballinger, were originally intended for major drama productions only and have proven to be very successful in this field, we have, with our more highly developed technology, expanded these practices for the lighting of television studios.More
We have now designed additional optics to be placed in front of our focusing dedolights. They are computer-designed, based on our many years of experience in optical design for focusing lights. Such parallel beam adapters are now available for each and every one of the focusing dedolights. Our parallel beam adapters have been very carefully calculated to match the performance of the optical system and each of our focusing dedolights. Thus, some of those may have the same appearance and same diameter, but you have to watch out, which parallel beam adapter performs best with each light.More
The image shows the light coming from the parallel beam projector PB70, shining onto the hard, big 3x3ft (100x100cm) reflector R1, which is redirecting the light. Redirecting the light does not change the character, nor does it influence much the beam angle of the redirected light. The redirected light now is used by reflector #R2, which could be a reflector #2, relatively hard, changing the direction of the light towards R4, which would be a softer, gentler reflector, possibly surface #3 or surface #4, spreading the angle of exit, thus, acting as a gentler fill light on the person behind the desk, whilst reflector R3 could be surface #2 or #3, reflecting the light onto the person, possibly acting as a key light.More
The brand name Eflect describes reflected light for creative elements and backgrounds. Who can use Eflect? Even the single image creator who travels has to use lighting on the move but still wants to have access to all the creative choices. Eflect can also be used for major effect in studios, theatres, shows as an infinite choice of creative effect. Table top – we are working on a miniature version of Eflect for the use of table top shooting, suitable for both still photography and moving images For the smallest crew, the Eflect system can be used to complement our smallest kits of focusing LED lights. You simply add a gooseneck arm with a magnet to attach Eflect reflectors.More
Ian Murray is a professional cinematographer; he has worked in the TV and film industry for over 22 years and has carved a distinguished career in commercial advertising production over the last 20 years. Ian suffered with dyslexia and truly found his forte when he enrolled with the London College of Printing and studied and passed the BA in Film and Video with the only Distinction in his year.More
The inverse square law applies to point light sources or Fresnel lights and focusing lights: Double the distance – one quarter of the light. When the light source is close to the talent, this will produce the effect of changing light intensity as soon as the talent moves closer to the light source or further away. In order to overcome these effects, we have several ways and thoughts:More
