sriyachoudhury2-code/photobooth ? reverse-engineered prompt

Build me a simple photobooth web app where someone can open the page, use their webcam in the browser, take a photo, apply a few basic filters, and save it. I want a clean React frontend that feels easy to use, with a live camera view, a capture button, controls for the filters, and a gallery of saved photos.

It should send captured images to a backend API, and the backend should store and serve the images from MongoDB using GridFS. Add the basic routes needed to upload a photo, list saved photos, and view them later in the gallery. Keep it lightweight and easy to run locally, with clear setup instructions for the frontend and backend. If you need to check current docs for webcam or GridFS handling, look them up online.
