Morphology unveiling [28]. (a) IC 405, Spitzer IRAC camera 8.0 m image (France et al. [29]); filaments and a bow shock near HD34078 (see the red cross “x” in Figure 3(a)). The brightness is proportional to the flux (logarithmic scale). (b) Brightness is proportional to the module of the gradient of flux (logarithmic scale); this way of looking at astronomical images facilitates analysis of nebular morphology, outflows, jets, embedded sources, and shock fronts.
