Line-of-sight integrated emissivities of the same exponential disc (Re, he) = (3.5, 0.1) model as a function of longitude and latitude for z0 = 0 (left) and +50 pc (right). The images have been normalised to the symmetric case and thus contain the same absolute flux. Clearly, the contrast in the right image is higher, but the flux is more spread out into a larger number of pixels.
