Likewise in polarized light, image brightness is governed by the illumination intensity … Although there are instances where an intense color can be consider bright, this can be a misleading term when try to describe intensity. 0.000000 Luminance refers to the absolute amount of light emitted by an object per unit area, whereas luminosity refers to the perceived brightness of that object by a human observer. 95.000000 The problem is that we constantly use the word colloquially to describe how things "appear" to us – it's a bright sunny day, that bulb is a bit bright, etc. I would describe the process of uniformly brightening the image as increasing intensity while leaving the contrast unchanged in the whole image. Intensity can also be considered as the brightness or dullness of a color.
