Wearing masks during the COVID-19 pandemic is an important measure to prevent the spread of the virus. To motivate other people not to take off their masks for photos at the rides, Disney photoshopped their visitors.
The company has now discontinued the practice, but the photographs have been spotted on several guests at Disney World while using the rides. One of these masks can be found in the photo below.
Many believe that digital masks were intended to discourage visitors from taking off masks for photography. People are theoretically less likely to endanger others if they know the mask will appear on their face anyway.
Disney expects visitors to the park to wear masks whenever they are not eating or drinking while stationary.
