To derive the metallicities of M3 and M5, we used the shape of red giant branch, horizontal branch magnitude, and red giant branch bump on the (V - I) - V color magnitude diagrams. [Fe/H] values ranging -1.46 -1.69 for M3, and -1.00 -1.49 for M5 are estimated. This result leads the morpholgies of re...
