为了更得心应手地使用LED灯具进行拍摄,了解LED的光谱( color spectrum) ,色域 (color gamut),普朗克黑体曲线( Planckian black-body curve)和及其相关的色温(color tempertaure) 对理解LED的基本概念十分重要。 什么是色温?(Color temperature) 我们先从“色温”真正的定义说起。 自然的白织(incandescent)*光源——...
LED术语和实际应用指南光谱(spectrum) 表示相对于光的波长,光的强度的分布。LED的光谱一般为单色LED, 例如蓝色LED以波长470nm时为峰值呈山峰分布,以峰值波长较短的紫外 领域和峰值波长较长的绿色领域为光的强度的测定极限。而白炽灯的光谱, 其发光强度广泛分布于400nm多的蓝色领域至700nm多的近红外领域,在紫 外...
How light bend within a lens depends on the wavelength of the light. The light transmitted through a lens is scattered into the seven-color spectrum, like an rainbow and forms an image at a certain point. That is, the formation of the images position differs for each color. Depth of fiel...
