Camera Raw preview navigation
The Camera Raw dialog's preview has Zoom, Hand, Fit in View, 100%, and zoom preset controls at the bottom left.
Choose Fit in View, or press Ctrl+0 on Windows/Linux (Command+0 on macOS), to fit the whole image inside the preview.
At 100%, one source pixel maps to one physical display pixel, including HiDPI. The native preview refines the processed source in the background so texture, sharpening, and grain can be inspected beyond the reduced proxy's resolution.
Controls
| Action | Windows / Linux | macOS |
|---|---|---|

Zoom and pan are view state: they do not change filter parameters or document history. Before/After keeps the same position; colour probes and clipping overlays follow the image coordinates. Cancel discards the filter; OK applies it through the existing Camera Raw command.
Preview limits
The fast proxy remains available while native refinement is pending. Processed full-resolution refinement is limited to 64 megapixels because the existing engine allocates full-image temporary buffers. Larger sources and failed refinement retain the proxy with a notification. Only the visible crop is uploaded to the GPU (at most 16,777,216 pixels and the device texture-size limit). The initial preview domain is bounded to 512 megapixels, including sparse content outside the canvas. Histogram and vectorscope statistics remain proxy-based. WebAssembly retains the processed proxy until a browser worker path is available.
