Take a look at the `spotlightHighlight(_:_:_:)`, `colorHighlight(_:_:_:)`, and `blur(_:_:_:)` functions in **DepthImageFilters.swift** from the final project. Each of these functions converts a `CIImage` to a `CGImage` to a `UIImage`. You should be able to do the same using the `CIImage` from the depth map to create a `UIImage` that can be saved. ---

This tutorial is more than six months old so questions are no longer supported at the moment for it. Thank you! ---
