<span class=normal>Rakeysh OmPrakash Mehras Delhi-6 might have failed to woo the audience at the box office, but if one were to talk about the visual effects (vfx) work in the movie - done by the couple of Indian studios - the effort is really commendable.<BR><BR> <br><p class=clear>&nbsp;</p>Various vfx techniques, right from compositing, matte painting, background plates (BG), wire removal and many more, went in creating shots which portrayed the look and feel of real Delhi, though most of the sequences were not actually shot in Delhi for security reasons. <BR><BR> <br><p class=clear>&nbsp;</p>For a behind-the-scenes vfx case study of the movie, we spoke to Chennai-based post production house Prasad EFX, which has worked on close to 425 shots for the movie. With around 50 artists, it took 3.5 months to complete all the shots. Kilari Hima Kumar, Executive Producer-VFX, Prasad EFX says, It was a great and wonderful experience working with the director Rakeysh OmPrakash Mehra and the team under the supervision of Craig Mumma - the vfx supervisor for the movie. <BR><BR> <br><p class=clear>&nbsp;</p>Apart from Prasad EFX, Mumbai-based Prana Studios also worked on few shots. Here is the breakdown of a few key shots worked on by Prasad EFX: <BR><BR><br><p class=clear>&nbsp;</p><amp-img width=1.33 height=1 layout=responsive src=https://images.bollywoodhungama.com/img/feature/09/mar/vfx1.jpg></amp-img><BR><br><p>&nbsp;</p><span class=normal><br><p class=clear>&nbsp;</p><amp-img width=1.33 height=1 layout=responsive src=https://images.bollywoodhungama.com/img/feature/09/mar/vfx2.jpg></amp-img><BR><br><p>&nbsp;</p><span class=normal><BR><br><p class=clear>&nbsp;</p>Terrace Extension<BR><BR><br><p class=clear>&nbsp;</p>The terrace shots of Delhi 6 were shot on set in Jaipur but were given the feel of Delhi in post production. Original backgrounds were replaced by images shot in Delhi. The key challenge in this shot was extending the generic terraces, building the geographic landmarks of the area like Jama Masjid, Golden Temple, Red Fort, with their respective geographical positions. <BR><BR><br><p class=clear>&nbsp;</p>Craig Mumma had suggested and guided the creation of a 360 degree Delhi geo-environment in 3D with using Delhi terrace photographs. Then we tracked the shots and placed the geos in the respective positions. We had executed about 164 terrace extension shots in this film, says Himakumar.</span>
