# 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 |
|
|
|---|---|---|
|
|
| Select Zoom | Z | Z |
|
|
| Scrub zoom in / out | Left-drag right / left with Zoom | Same |
|
|
| Toggle Fit / 100% | Click with Zoom | Same |
|
|
| Zoom a selected region | Ctrl+drag | Command+drag |
|
|
| Select Hand | H | H |
|
|
| Temporary pan | Space+drag, or middle-button drag | Same |
|
|
| Pointer-anchored zoom | Alt+wheel, or pinch | Option+wheel, or pinch |
|
|
| Zoom in / out | Ctrl+plus / minus | Command+plus / minus |
|
|
| Fit in View | Ctrl+0 | Command+0 |
|
|
| Actual size | Ctrl+Alt+0 | Command+Option+0 |
|
|
| Zoom presets | Bottom-left dropdown or right-click menu | Same |
|
|
|
|
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.
