Business Sectors (Suites): Visual Effects
Developed by: ScreenSkills

Overview

This standard is about removing or “painting out” unwanted content from plates. This could include rigs, scratches, dust, blemishes from developing chemicals, company logos, safety harnesses, markers used for blue or green screen, modern elements from period drama and people that should not be in shot such as animal handlers or puppeteers.

This standard is for those involved with Paint and Prep or Compositing.
