Open RAW and inspect detail

Understand the difference between the editor preview and the source.

The editor uses a bounded preview so that adjustments stay responsive. Professional export renders from the native source. A preview dimension shown while editing is not, by itself, the maximum export resolution.

The method

Step by step.

  1. Open a supported RAW or raster file. On macOS, RAW development uses the available Apple RAW support; camera compatibility can vary.
  2. Wait for loading to settle. A fast initial preview and a completed source preparation are different stages.
  3. Use Fit for composition, then 100% for edge and noise inspection. Pan with the Hand tool.
  4. For a JPEG, remember that a high-bit-depth workflow does not recover information already lost to compression or clipping.
  5. If a file does not open, verify the drive is connected, the file is intact, and the camera format is supported. Try a known-good raster file to isolate a decoding issue.

At your own pace

Try it.

Inspect a bright chrome edge at Fit and 100%. Look for halos before increasing Sharpen.

Watch for

Do not judge final TIFF bit depth or full-resolution export quality from a screenshot of the editor.
