  Using a sample of 471 million BBbar events collected with the BaBar detector,
we study the sum of seven exclusive final states B->X_s(d) gamma, where X_s(d)
is a strange (non-strange) hadronic system with a mass of up to 2.0GeV/c^2.
After correcting for unobserved decay modes, we obtain a branching fraction for
b->d gamma of (9.2 +/- 2.0(stat.) +/- 2.3(syst.))x10^-6 in this mass range, and
a branching fraction for b->s gamma of (23.0 +/- 0.8(stat.) +/-
3.0(syst.))x10^-5 in the same mass range. We find BF(b->dgamma) / BF(b->sgamma)
= 0.040 +/- 0.009(stat.) +/- 0.010(syst.), from which we determine
|V_td/V_ts|=0.199 +/- 0.022(stat.) +/- 0.024(syst.) +/- 0.002(th.).
