Specular or diffused light is also a transmitted form of light in photography. All surfaces, smooth or not, reflect some form of specular and diffused light, but in commonality we see more diffused light around us, thus this is how most photographers illuminate their subjects as the light appears more natural. Diffused light is light that strikes irregular or not so smooth surfaces, thus the light scatters in many directions, less focused, less contrast, softer and sweeter light. This is a more focused, reflected light and in photography, it’s our highlights for the most part, or any bright spots in our final image. Specular light is formed by equal angles of light striking a smooth surface and reflecting back. One other factor involved in determining shape, color, contrast and form in what the camera and we capture is the physics rule, the Law of Reflection, aka the Angle of Incidence Equals the Angle of Reflection. It’s this rule that also determines if reflected light is specular or diffused. Two of those basics, which are also part of color theory, are that reflected light is what the human eyes and cameras capture to determine hue, brightness and saturation of color. In order to use daylight properly however, photographers have to understand a few basics. Flash aside, photographers use this natural light, or daylight, to illuminate their subjects-in essence, photographers are merely capturing the reflected light off their subjects. When photographers go outdoors and photograph models out in the open, they are working with natural daylight, assuming they are not using fill flash to either lighten up shadows or overpower the sun with flash. So now that brings me to the main topic of this photography tip, natural, ambient and existing light-of which daylight can play different roles in all three. These lights vary in color temperature, measured in Kelvin, the most common types are on average, 5400K for flash and 3200K for tungsten. She is highlighted with sunlight being reflected off a SUNBOUNCE PRO with a SPARKLING SUN fabric.Įach form of artificial light has its own qualities, such as harshness or softness, specular or diffused, color rendition index and specific wavelengths to name a few. The natural light is the main ambient light in this scene with model Dilara.
