How to Use Affinity Photo’s extensions

1 Add Affinity Photo

Select an image in Photos and press ® to switch to the app’s editing mode. At the bottom of the tools on the right, click Extensions and choose More to see those that are installed; add check marks to those you want to use.

2 Edit in Affinity Photo

Here we want to replace the overexposed sky with a nicer one. This kind of cutout work can only be done by choosing Edit in Affinity Photo. When you do so, that app will spring into life and the picture will open in it.

3 Finish the job

After making changes in another app, to complete the round trip back to Photos press ç+S to save your edits, then ç+W to close the picture. If you don’t close it, your changes won’t successfully return to Photos.

4 Reset your image

If you later decide an edit wasn’t quite what you wanted, don’t worry; the original data is still present. Remember you can always choose Image > Revert to Original in Photos. Your original shot is never lost!

5 Editing within Photos

Only a few extensions require you to pass pictures to third-party apps; others work within Photos. Click Extensions again and pick Affinity Haze Removal. This provides a very useful way to remove low contrast from landscape photos.

6 Haze removal

Adjust the Distance and Strength sliders and drag the before/after divider to check the results; if the pic is too dark, use the Exposure Correction slider to fix it. Click Save Changes to return to Photos’ normal editing mode.
