Check adjustment status
One or more status icons may be displayed to the right of an adjustment's heading. Hover over each for more information.
- A blue information icon indicates success in auto-selecting a lens profile, or that the Develop Assistant is not set to auto-select a profile.
- A yellow warning icon indicates something could not be done. The Develop Assistant may not have been able to auto-select a lens profile for some reason; the image contains insufficient metadata to perform the adjustment; or corrections have already been applied to the image.
Any status indicator related to the Develop Assistant is cleared if you select a profile manually.
Though Affinity Photo may determine a suitable lens profile for your image, in the following circumstances one or more adjustments may be turned off. They can be turned on manually, if you want.
- The image is not a linear RAW format—its light values are logarithmic. This is rare.
- The image is not a RAW format. For example, you opened a JPEG file and then selected Develop Persona.
- In the Develop Assistant, RAW Engine is set to Apple (Core Image RAW).
- The image contains insufficient metadata, such as focal length and aperture, to perform some aspects of correction.
- Other software has already corrected the image.
- Preset—manages adjustment presets via a pop-up menu.
- Add Preset—saves the current adjustment settings as a named preset for later use. The pop-up menu populates with the preset name on saving.
- Delete Preset—deletes the preset currently checked in the Preset pop-up menu.
- Default—reverts the current adjustment settings back to default settings.
- Active/Inactive—when checked, the adjustment is applied to the image.
- Reset—sets adjustment slider(s) back to default.
