The hadronic photon structure function F-2(gamma)(x,Q(2)) is measured from data taken with the ALEPH detector at LEP. At centre-of-mass energies between roots=189 GeV and 207 GeV an integrated luminosity of 548.4 pb(-1) is analyzed in two ranges of Q(2) with [Q(2)] =17.3 GeV2 and 67.2 GeV2. Detector effects and acceptance are corrected for with a Tikhonov unfolding procedure. The results are compared to theoretical predictions and measurements from other experiments.
