How Cell Size Affects the Spread of Light
Cell size, measured in degrees, describes the maximum angle of the off-axis light. A 30° Soft Egg Crate® is one of our narrowest models, giving you the ability to aggressively control light; this model creates significant occlusion at close distances. As cell width increases, the blocking of off-axis light is wider. A 60° Soft Egg Crate® is the widest model and is therefore the most modest light blocking tool.
The 30°/50° Soft Egg Crate® models offer two variations in a single Lighttools® Soft Egg Crate®. You can vary the amount of soft light spread in four directions by rotating these models.
Why Occlusion Matters
Occlusion refers to the blocking of light by the Soft Egg Crate® cells at close distances. This changes light distribution and the effective size of the source, affecting the softness of light. Soft light depends on the size of the diffuser and the distance of the diffuser to subject.
Soft Egg Crates®, with uniformed parallel cells, block and control off-axis soft light according to how closely the cells are spaced. The reduced near-to-far ratio is created with Soft Egg Crates® due to increased occlusion close to the source. At closer distances the light size, and output, is reduced proportionately due to the occlusion of the cells at that range. As the subject moves closer to the source, less light reaches them, because the angle of the outer cells blocks much of the light output. This occlusion is minimized as the subject moves further from the source, along the center-axis.
The following illustrations show occlusion variations with 30°, 40°, and 50° cell sizes with an 8x8 ft diffused light source and at a distance of 8.6” to the subject.
