In Jainism, a satvi (a female renunciate) follows strict vows of non-attachment and non-possession (aparigraha) and lives a simple, meditative life. Because cameras are modern possessions and can be sources of distraction or attachment, satvis generally avoid using them. There can be differences between Digambar and Śvetāmbara practices, and in some communities a teacher or guru might permit limited use only for specific religious activities or documentation, but the usual practice is to refrain from personal photography or videography.

If you’re asking in a particular community or by a specific satvi, the exact guidance would come from her guru or senior nuns in that sangh.
