Society for Social Work & Welfare
The Photographic Club of S. Thomas’ College plays a key role not only in documenting the day to day activities of the school but also, Among the most active societies in College. The Photographic Club is a society which encourages young Thomians to perceive and capture moments in time, gradually exposing the artist which resides within. Whilst pursuing photography in an artistic sense we pride ourselves in our ability to provide media coverage for all events in the school calendar rendering service to our school in any way we can.Latest Project
