'John Snow Charity Fashion Show' (JSCFS) is a college fashion show in Durham, having been created in 2020, which Callum has been involved with since its fruition, helping to shape its creative enterprise. On the executive committee as Photographer for three consecutive years, Callum has been in charge of exec and model headshots, video releases, BTS photography and more.

​

In 2021, when a show was not possible due to COVID restrictions, Callum organised a model fundraiser in conjunction with RT Projects' 'Run to the Sun' initiative to help raise close to £800 of the £2,200 grand total. He also organised and produced a video shoot with a selection of models to post on social media and provide an alternative, virtual show.
