We present a method to map the total intrinsic reddening of a foregroundextinguishing medium via the analysis of spectral energy distributions (SEDs)of background galaxies. In this pilot study, we implement this technique in twodistinct regions of the Small Magellanic Cloud (SMC) - the bar and the southernoutskirts - using a combination of optical and near-infrared$ugrizYJK_{\mathrm{s}}$ broadband imaging. We adopt the LePhare$\chi^{2}$-minimisation SED-fitting routine and various samples of galaxiesand/or quasi-stellar objects to investigate the intrinsic reddening. We findthat only when we construct reddening maps using objects classified as galaxieswith low levels of intrinsic reddening (i.e. ellipticals/lenticulars andearly-type spirals), the resultant maps are consistent with previous literaturedeterminations i.e. the intrinsic reddening of the SMC bar is higher than thatin the outer environs. We employ two sets of galaxy templates - one theoreticaland one empirical - to test for template dependencies in the resultingreddening maps and find that the theoretical templates imply systematicallyhigher reddening values by up to 0.20 mag in $E(B-V)$. A comparison withprevious reddening maps, based on the stellar components of the SMC, typicallyshows reasonable agreement. There is, however, significant variation amongstthe literature reddening maps as to the level of intrinsic reddening associatedwith the bar. Thus, it is difficult to unambiguously state that instances ofsignificant discrepancies are the result of appreciable levels of dust notaccounted for in some literature reddening maps or whether they reflect issueswith our adopted methodology.
