Green screen removal task 1:
For our homework in Nuke, we worked on a green screen compositing exercise. The task involved removing the green screen background from footage of a person filmed in a lab environment and replacing it with a different background.
During the process, we experimented with different keying techniques, including IBK and other keyers, to achieve a cleaner separation between the subject and the background. This helped us understand how important lighting, color balance, and edge details are when creating a believable composite.
The exercise showed how compositing is not just about removing a background, but also about blending elements together so the final image feels natural and visually consistent.
Green screen removal task 2:
For the second homework in Nuke, we worked on a more advanced green screen compositing exercise. The footage showed a woman with long hair moving in the wind while snow was falling around her.
This project was more complex than simply removing and replacing the background. Besides creating a clean key for the subject, we also had to separate the snow so that some particles appeared behind her and others in front of her. This helped create a stronger sense of depth and made the final composition feel more realistic and immersive.
The movement of the hair and the overlapping snow made the keying process more difficult, since fine details and transparency had to be preserved carefully. Through this exercise, we explored more advanced compositing techniques and gained a better understanding of how layered visual effects are built.
