"Multiple Populations of GCs Seen from Ca uvby Photometry"
 

During the last five years, I have carried out Sejong Ca uvby Survey for globular clusters and the selected Galactic bulge field using the CTIO 1m telescope. My results showed that Ca uvby photometry can provide a very powerful method to distinguish multiple populations in GCs. In this talk, I will present some highlights of my survey.
