Why you need this
Text readability on photos
A dark overlay at 40β60% opacity turns any busy background photo into a canvas where white text is perfectly legible β the standard trick for hero banners and Instagram stories.
Brand colour tinting
Apply your brand colour at low opacity (15β30%) to unify a mix of stock photos. Suddenly every image looks like it belongs to the same campaign.
Gradient overlays for cinematic feel
Bottom Fade is the secret weapon for video thumbnails β darken the lower half so a title card sits perfectly at the bottom without obscuring the main subject.
Blend modes for mood
Multiply deepens shadows for drama. Screen lifts highlights for a dreamy look. Color tints without affecting brightness β great for duotone effects.
Vignette / Feather
The Feather slider fades the overlay toward the centre of the image, drawing the viewer's eye inward β classic portrait and product photo technique.
