Sharpen a photo or video on Mac
The Sharpen adjustment changes photos and videos by making edges crisper and better defined.
Go to the Photos app on your Mac.
Double-click a photo or video, then click Edit in the toolbar.
Click Adjust in the toolbar, then click Sharpen.
Drag the sliders to adjust the sharpness.
Intensity: Adjusts the strength of the sharpened edges.
Edges: Sets the threshold for which groups of pixels are edges and which ones aren’t.
Falloff: Makes the sharpening effect more or less prominent. Increasing the falloff value makes the sharpening more severe; decreasing it softens the effect.
Tip: Hold the pointer over a slider and press and hold the Option key to extend the slider’s range of values.
