![]() It’s just so much more fun than just pushing the button. Using the effect of reflections can completely shift the view on an image from something simple boring and straightforward to crazy abstract and artistic. Reflections can provide the most amazing and interesting effects. Here we are trying to investigate options that do not involve Photoshop manipulation. Reflections can be hard to capture because you might find yourself on the ground in the mud and literally pressed to the wall. I use Reflection in Light Painting Photography very often. Artistically you can create images with a special twist for the artistic and engineers eye. Is the viewer going to figure it out? The photographer as well as the viewer is required to have a decent comprehension of the perspective and the angles and corners the light will go. The challenge to the curious brain is what I look for. In my opinion that exactly why I am drawn towards it. To make it POP using a reflection in your photography or even in your Light Painting is a challenging task. There is some point reflection, while most light scatters.A reflection always makes an image a little bit more interesting.a white rough-surfac cardboard, like artists mount card A diffusion surface creates an illuminated spot.No reflection, you will see most light as scattered.a painted matt black surface like a black board An absorbing surface minimises reflection.Examples when you shine a beam at different surfaces: This would create a bright spot of reflecting light around the point the light strikes. It may also reflect some light, and diffuse some light. It is a surface that might absorb some of the light energy (eg. The diagram below is a more realistic version of how light scatters on a diffusion surface.Ī partially absorbing, diffusing and reflecting surface might be white gloss paint. So you would see light coming off it only as a proportion of the total light striking the surface. In the studio, an effective diffusion surface scatters light in all directions. High reflection, low scatter – silver foil: reflector.Low reflection, high scatter – white card: diffuser.The amount of light reflected depends on the how well the surface reflects rather than diffuses. A percentage of the light may be reflected in a reduced specular reflection. The scattered light radiates from around the strike point. Some light coming off the surface you would see as diffused light. ![]() Some of the light, in reality, may be absorbed by the surface. Remember, the perfect diffusion reflection surface does not exist. Note: The diagram is only showing two dimensions – in reality the hemisphere is three dimensional around the light strike-point. In a diffusion reflection, you would see light reflected from a strike point in a hemisphere of illumination. It is not the best model of how a light beam reacts in reality. This model of diffusion is mainly of interest to physicists. Although the diagram is only two dimensional (2D) the light scatter forms a hemisphere (3D) around a light strike-point. The diagram shows you the way light is scattered by a perfect diffusion surface. The total light in the beam spreads over the whole illuminated space, thus reducing the amount hitting your eye. Your eye, fixed at one point, sees a reduced amount of light. ![]() This scatter occurs around the point the light strikes the diffusion surface. In a perfect diffusion reflection, all the light will form a hemisphere of illumination. This type of reflection occurs when an incident ray of light strikes a surface and the light is scattered. The devices that we might use to create scattered light are called diffusers. The process that scatters light is what we call diffusion. It is usually used to help soften light or can be directed so as to reduce harsh shadows. In photography, something that creates diffusion or diffused light is a device that evenly scatters the light from a light source. Diffusion diffusion reflection (the process of…) ![]()
