<span class=normal>We had a body double for Katrina to match the boys eye line as a reference point, while filming the house plates. One interesting layer was the light pass, which we shot by rigging up a trolley track with a set of Kino Flo lights. We did this as Carlos the cinematographer of the film wanted Katrina to have an angelic look emitting white light, this would emulate the light affecting the walls and other objects in the room. We moved the rigged up lights on the same path as how Katrina would hover after she plate would be composited. This made the lights and shadow interact with the room. The Kino Flo light pass was used only for effect of the light on the walls and other objects in the room. All relevant information such as lens data, camera height, focal distance etc. was recorded as we had to replicate the cameras positions for shooting Katrinas plate. Our compositors were present on set to match the plates and get approval from Zoya, this was important as the Katrinas dimensions were to seem credible enough like she was actually in that room. Once we filmed all our plates, we digitally created fairy wings using CGI and made sure she had the right angelic look which Zoya had visualized. </span><BR><BR><br><p class=clear>&nbsp;</p><amp-img width=1.33 height=1 layout=responsive src=https://images.bollywoodhungama.com/img/feature/13/may/vfxbombay4.jpg></amp-img>
