We investigate the effects of dust on Large Magellanic Cloud (LMC) H II region spectral energy distributions using arcminute-resolution far-ultraviolet (FUV), HЮБ, far-infrared (FIR), and radio images. Widely used indicators of the amount of light lost to dust (attenuation) at HЮБ and in the FUV correlate with each other, although often with substantial scatter. ...
