To work in Develop Persona:
- Do one of the following:
- Open a raw image. Develop Persona will analyze the data and pre-process it, ready for editing.*
- Select a pixel layer and then, from the Persona toolbar, click Develop Persona.
- Activate your preferred view mode.
- Adjust the image using the various panel options and tools.
- (Optional) Sync applied settings within the view and repeat the above step.
-
On the context toolbar, select Develop.
The photo or layer will adopt all the settings as displayed in the 'None' or 'After' view. The 'Before' view is for comparison purposes only.
To activate view modes:
On the Toolbar, do one of the following:
- Click None to display the processed image in isolation.
- Click Split to display both processed and original raw image on the same page. A sliding divider can be repositioned to view the image 'Before' and 'After' processing.
- Click Mirror to display processed and original raw image side-by-side on separate pages. Panning and zooming affects both pages simultaneously so the same area is always displayed in both pages.
To synchronize applied settings in view modes:
On the Toolbar, do one of the following:
- Click Sync Before to update the 'Before' view to the most recent applied settings, i.e. those in the 'After' view.
- Click Sync After to revert the settings applied in the 'After' view back to the settings shown in the 'Before' view.
- Click Swap to switch the applied settings between the views.
To show clipping:
On the Toolbar, do one of the following:
- Click Show Clipped Highlights to display all 'blown' highlights as a high-contrast red color.
- Click Show Clipped Shadows to display all clipped shadow areas as a high-contrast blue color.
- Click Show Clipped Tones to display all clipped midtone areas as a high-contrast yellow color.
To rotate your raw image:
On the Toolbar, do one of the following:
- Click Rotate Counter-clockwise to rotate the image counter-clockwise by 90°.
- Click Rotate Clockwise to rotate the image clockwise by 90°.
To change initial develop settings:
On the Toolbar, do the following:
- Click the Develop Assistant to open its settings dialog.
- Choose from the following settings:
- RAW Engine: Provides a choice of RAW processing engines for you to use—Affinity's own Serif Labs engine (used by default) or Apple's Core Image RAW engine.
- Lens corrections: Enable or disable automatic lens correction for supported camera lens profiles. Lens profiles are installed with the app. If a camera is not included (perhaps a new model), you can include it by adding its profile—a downloaded Lensfun XML file or Adobe Lens Correction Profile (LCP)—to the database by using Preferences>General.
- Noise reduction: Automatically enables either color noise reduction, color and luminance noise reduction, or disables any initial noise reduction. Color noise reduction is recommended for the vast majority of camera raw images.
- RAW output format: Choose between RGB (16 bit) or RGB (32 bit HDR) output when developing a raw image. Choosing RGB (32 bit HDR) allows you to maintain a full 32-bit float environment from initial raw development to export and take advantage of extra precision.
- Tone curve: If the default 'Apply tone curve' option is active, your raw image is adjusted using a suggested tone curve. The 'Take no action' option makes no tonal correction; the image can be altered within the Basic panel later.
- Alert when assistant takes an action: When checked, a pop-up message appears on loading the RAW image to indicate that adjustments have been applied automatically.
- Exposure bias: Choose whether to apply exposure bias value if stored in the raw image's EXIF data. Like Histogram stretch, both 'default' and 'initial' give the same results but reports zeroed or actual values, respectively. The 'Take no action' option ignores the exposure bias value.
- Map default region: Sets the map that displays in the Location panel to a chosen region, if the raw image contains no GPS location data in its EXIF data.
