As far as I understand, radiance is a measure of the intensity of light in a direction defined as a differential cone . It's measure is Flux per solid angle per projected area.  $L = \frac{d\phi}{d\omega dA^\perp} = \frac{d\phi}{d\omega dAcos(\theta)} $ . Using this definition, it seems like as the $\theta$ angle increases, radiance increases, thus light is somehow more intense in a direction nearly perpendicular to the normal at point p. This contradicts my intuition.Where am I interpreting this wrong?
Radiance at a nearly perpendicular angle is almost infinite?
