A Lead Compositor and Technical Director, Mr.Ganesh Shankar conducted a workshop on ‘VFX Compositing’, at the ICAT, Chennai campus on 9th of April, 2014. The workshop was conducted for the 2nd and 3rd year students of the VFX department. The session focused on the essential tools and industrial methods of keying and compositing by using leading compositing software. Mr.Ganesh Shankar also shared the usage of color correcting film plates and multi pass compositing. During the 4 hour workshop, the students had the opportunity to work on some industrial footage, enabling them to composite CG elements and live action footage, which they found to be very beneficial in understanding the concepts practically. Forthcoming workshops will follow up on Camera Projection techniques and Outdoor Shooting techniques.
