First attempts at creating shadow screens

Shadow Screen against trace paper

During our session of light and shadow we were introduced to look at shadows and how they can be manipulated in different ways. At the beginning of our first inclass shadow study I wanted to see how shadow shapes can be manipulated by folded openings that can possibly apply to shading membranes for buildings.  In exploring the effects of different aperture sizes on one screen demonstrates the capability of how the minor changes made to half the screen can affect the overall pattern of a set of shadows.

The screen is cut symmetrically with openings on one half allowing more light to penetrate. On the other half of the openings only the mininmum amount of light is allowed to pass through. The effect at different angles creates almost a sundial effect. Also the symmetrical pattern with different aperture sizes creates a modular piece that placed in a sequence could create very unusual patterns.

Shadow Panels is about the discovery of shadows and shaded surfaces through the exploration of material and technique.  These are the first of my studies of the Shadow Panels, I ave been exploring the nature of shadows through the manipulation of layered surfaces.

First starting with a regularized panel of 1/8″ bristol strips each of which having different curvature in the z-dimension, I explored the layering and interplay of shadows, light and material. Finding beauty in the playful nature of these delicate strips and their shadows.  The composition of the strips with their shadows creates a depth of intrigue.

The second panel explores the same material but through the form of a web.  These shadows are increasingly intriguing as the panel is held at an angle to the receiving surface.  The shadows do not build upon one another like in the first panel, but they create intriguing patterns that are ephemeral as the lighting changes.

The third panel begins to explore the phenomenon of reflection and refraction.  Layering acrylic strips of varying depth together creates two surfaces in which to study.  One being smooth and planar the other showing the relief from the varying depths.  Through this panel I am beginning to explore shadow and light through light passing through a surface instead of passing around.  I am intrigued by the resulting caustic like patterns that are formed when reflections are layered upon the shadows from these varying strips.

These panels have begun to barely scratch the surface of what I want to explore through this class.  I am looking to explore the ideas of digital fabrication and what those tools can do to help us as designers in shaping light.  The tools in which I wish to explore are not set in stone as I believe that tools should be used to solve a problem, not as a way or means of exploration.  This however will not limit me in my study, as I will be exploring fabrication and modeling techniques throughout the term, settling upon the method that best suits my final project.  As of right now I am not entirely sure of what my final project will be, although I do have ideas of what I want to explore.  I am interested in manipulating light based on human interaction as well as the way in which light and shadow can inform the way we use space.  Each of these ideas can manifest themselves in different ways, from a luminaire or building facade panel to an installation.

Light Studies

My first exploration in creating a shadow study panel was relatively unsuccessful.  I created a hyperbolic shape out of fishing line, anticipating that the translucent quality of the fishing line would have some interesting visual qualities to it.  It rendered more or less opaque, and the hyperbola I created was too shallow to really be noticeable.  But in thinking of how to secure the fishing line to the frame, I inadvertently created some more interesting shadows.  Each strand of fishing line is held in tension between two posts.  After tensioning all of the lines, I slowly began to appreciate the connections more and more.  The frayed edges became much more dramatic than the original hyperbolic shape I had intended.

I’m also very interested in the caustics produced when light passes through water.  For this exploration I have been using zip-lock bags filled with water to create the desired effect.  The position of the bag drastically changes the effect produced, so the direction the bags are oriented in in the final panel will be important to consider.  It would be interesting to explore the caustics created by other liquids of different colors and chemical make-up.

Light and Shadow First Experiments





Here are a few of the results of my initial light/shadow experiments.

I was mostly interested in the light/shadow effects involving some bright green moss I found. I used led’s for the lighting which is very directional. The moss tended to disperse the light, though the light levels where really low and it was difficult to get good photos with my camera. In the room it was more like a moss disco ballroom. I liked how the light tended to reveal the structure of the moss in a dramatic way.

I also played with using water, bubble wrap, and shape tracing patterns. One of the images I took over break of the coast at night, and the way the light bounced off particles in the air was unusual.

Light & Shadow – Preliminary Studies

BagO
GlassO
JarO

The three pictures are of a plastic bag, a small drinking glass, and square cookie jar respectively.  All images were created from found objects around my apartment, and the light source that was used was an old Sony projector that emits a default blue light.

The experience was unique.  My process started out by shining light through paper with cut geometric holes, then the use of textile meshes, and finally found glass.  The “found glass” proved to be the most interesting because while the glass looks smooth and flawless in everyday conditions, a light source reveals the opposite.  The light source revealed that the glass’s imperfections, but it is the imperfections that created interesting patterns of light and shadow.  To me the most interesting aspect of the the investigation was the what the overlapping of the same materials created.  With each image light passed the their respective materials at least twice before hitting the wall.  The overlaps created an interesting contrast between light and dark.  I will explore this aspect, along with the “imperfection” that materials create, further.

Light Modulators

In the reading excerpt by Moholy, Vision in Motion, he describes objects being photographed as light modulators.  Thinking of the object as not a thing by itself but as a tool that manipulates, catches, reflects, bounces, distorts and absorbs light.  Anything can be called a light modulator, including the human face.  Our first mini-assignment in class was to manipulate a material and just observe the shadows that can be created from it.  I created a “wheaties”-looking object using watercolor paper and linear cuts.  I found that by having many different light sources (by accident) actually created a more interesting shadow, with parts of it sharper and blurred depending on the intensity of the light source.

This light source layering effect reminded me very much of performance theater, where a scene is controlled very much by the lighting used.  This may be something I want to explore since my studio project is to design a performing arts center this quarter.  I am still not quite sure how I want to explore this – possibly through the use of paper, various cuts, or origami techniques.  I tested out a few origami tessellations and noticed how the larger the fold, the more dramatic the shadows are within the objects are.  I may try to test out different materials, such as tissue paper, mesh, or fabric to see what results I can get.

Light and Shadow: Shadow Panels












On the first day of class, during our 30 minute experimental shadow excursion,  I thought it would be cool to experiment with the translucent nature of trace paper.  I drew a pattern on a piece of paper that attempted to express a concept I have struggled with in the past:  Harnessing randomness and uncertainty.  I blew up the drawing in the copier, scanned it and printed two different versions on trace paper.  By overlaying the images with a slight gap, it created a interesting effect.  Unfortunately, It would not cast a shadow.

The logical next step was to print the same patterns on a translucent material.  This time, using a projector as the light source, I was able to cast a shadow.  I experimented with different surfaces…smooth wall, crumpled trace paper, my face.  All produced interesting effects.  One unintended consequence was the interesting reflections generated of the reflections.  By rotating the “light manipulator,” I could produce green, purple and white reflections.

The next step will be to experiment with cutting and folding paper.  I don’t think the pattern I chose was very successful for this project because the shadows produced are hard to differentiate.  I may choose another design for some of the other panels.

Shadows Assignment 1 – Thoughts











Light and Shadow:  First class of the 2011 Spring term.  In this class we were introduced to concepts of light and shadow and ended with a short workshop of creating images.  I focused on using different openings to reflect the light at different angles.  The most interesting proved to be the  punched “x” opening that created a ring of light around the opening.

I continued these studies at home.  I was interested in the affects of color and light and began to experiment with different colored glass containers

The next series of photos used clear glass.  I was interested in transparent objects’ shadows.  I used a glass cup filled with water and eventually adding opaque objects.  The circular shape of the glass bottom created a focal point of light.  I was surprised at the outcome when I added a plastic bag behind the glass.  The clear plastic diffused the variation of the light intensity resulting in a softer shadow.

In all of these studies, the location and intensity of the light source seem to predominate the outcome of the images.  I want to further investigate the impact of different light sources on my panels.  Using the same panel to generate different shadows by altering the light source.  I also want to further investigate transparent objects creating shadows.
