About Sivaji: Director Shanker wanted to change Rajini's wheatish complexion to a white European complexion. It was Directors brilliance and peak of his imagination. Indian Artists took this as a challenging task, because nobody has executed this type of concept in the world. To begin with, Indian artists did an in-depth study of the European complexion. They found that white skin reflects more light and has less shadow when compared to dark skin and is translucent in some areas. Therefore a simple color correction of the hero's skin would not achieve the desired effect.
For the shoot a London based young white lady with a fresh complexion and flushed cheeks was chosen and with the help of Cinematographer Mr. K.V.Anand every single shot of the hero was repeated with her because lighting conditions change in every shot. After the final edit all the 630 hero shots and 630 girl shots were scanned in 4K resolution. Each of the 9000 scanned frames ware rotoscoped to separate the body parts (face, hands, legs etc.). The white lady's skin was mapped onto the Super Star's image using Eyeon “Digital Fusion” software. Thus the Super Star got his glowing white complexion. There were two difficult aspects in this project. One was matching the girl's action with the hero's action and the second was matching both of their body proportions during mapping.
Though it sounds simple, the work involved was laborious and painstaking. Great attention was paid to detail right from the shoot until the final print. It has taken 25 dedicated CG technicians almost a year to achieve this 6 ½ min. feat.
Thanks for Info and Movies Indian Artists.
