Colour magnitude diagrams of Terzan 3 and IC 1276 are presented for the first time. The morphology of the horizontal and red giant branches indicates that they are metal rich ([Fe/H] ). They are considerably reddened, with (Terzan 3) and (IC 1276). Terzan 3 is located at a distance from the Sun ≈ 6.5 kpc, and IC 1276 at ≈ 4.0 kpc. Both clusters are in the Galactic Bulge. The photometries attain the main sequence turnoff regions, and a discussion of ages is given as compared to other bulge and halo globular clusters.
