A new photometric study of M3 was done in order to obtain fine details of sequences in the bright part of the color-magnitude diagram from V = 12 to V = 17. Since the (B-V)o,g color of the subgiants is a function of metallicity at the level of the HB, the chemical homogeneity of the M3 stars was studied by finding the intrinsic width of the subgiant branch at the level of the horizontal branch. Limits were also sought for the intrinsic width of the horizontal branch. It was found that the subgiant branch may have zero intrinsic width in color, that the horizontal branch has an intrinsic width in magnitude of about 0.3 mag, presumably due to evolution, and that there is no definite proof for any gap in the giant branch other than that near V = 13.4, similar to that found earlier in M15, but discounted then.
