The purpose of the priest facing away from the people is not to hide his face. In the EF the reason the priest faces the wall is to focus on the sacrifice.
Whether the camera catches his face or not the priest is not distracted unless the camera is in his face. Most likely this is not the case. Even in the OF the camera is farther from the priest than we think. That’s wha zoom button does.
As to the question regarding the Poor Clares being seen on TV that’s another issue.
St. Francis founded the Poor Clares as cloistered nuns, not as sisters. There were no such creatures as sisters until Vincent de Paul founded the Daughters of Charity.
However, St. Francis never bound the Poor Clares to the strict enclosure as the Trappistine, Benedictine or Carmelite nuns.
In fact, St. Clare left the cloister every Wednesday to have dinner with Francis and to provide him with spiritual direction. Many people don’t know that she was his spiritual director in later years after she became a Franciscan. She was also his advisor in the reform of the rule.
The answer to the question regarding the Poor Clares on TV is that it is not in conflict with Franciscan tradition.
The nuns are often interviewed on TV outside the cloister. Right now there are four or five of them in Arizona (I believe) building a new monastery. They live outside the cloister.
Poor Clares and Franciscan Friars who celebrate the EF are not as strict about it as other groups, because it’s not part of the Franciscan tradition. They are an exempt religious family. They have many exemptions that they can apply to their celebration of the liturgy that others do not have.
They also have some smal details that they include in the EF that others do not include, such as wearing the capuche when processing.
