1 Neural Filters are trained using machine learning, so they are capable of results that are not attainable using conventional algorithmic filters.
2 If you are connected to the Internet, you can download Neural Filters and use Neural Filters that process image data in the cloud. If you choose to participate in the Photoshop Improvement Program, an Internet connection allows your usage data and images to be sent to Adobe for use by researchers.
3 The Current Layer option applies the results of Neural Filters to the selected layer, permanently changing it (destructive editing). The other Output options apply the results of Neural Filters to a separate layer or as a Smart Filter, preserving a layer’s original state, so that you can start over at any time (nondestructive editing).
4 The Photo Restoration Neural Filters (and possibly Super Zoom) can help improve the quality of digitized images of old prints and slides. The Colorize Neural Filter can re-create colors for a black-and-white photo. JPEG Artifacts Removal can improve images that were saved at a low-quality JPEG compression setting. Depth Blur can help focus attention on the subject of a photo.
5 Neural Filters such as Landscape Mixer, Harmonization, and Color Transfer can help unify a composite by making its layers more visually consistent with each other.
