We describe the technique of absorption line imaging of galaxy disks using the Taurus Tunable Filter on the Anglo-Australian Telescope and demonstrate its sensitivity to the behaviour of spectral features associated with Mg and Fe. Radial profiles of Mg2 and Fe5270 line-strengths are presented for a sample of eight face-on spiral galaxies spanning a range of Hubble types. Signatures of phenomena including merger-induced star formation, HII rings and galactic bars are also reported. This study demonstrates the capacity of tunable filters to measure Mg and Fe line-strengths across the face of spiral galaxies, which can ultimately reveal clues about the star formation history and chemical evolution.
