What the opening frame is actually drawing
The halo is seven concentric vector strokes rather than one browser-dependent blur.
Spread controls reach while strength controls opacity, so a wide faint halo and a tight bright rim are separate decisions.
The glow is redrawn at output size and uses the photograph's short edge as its scale reference.
Where to judge it
Check the frame at thumbnail size first: if it disappears, widen it; if it becomes the subject, narrow it. Then inspect all four corners at full size. Corners reveal uneven joins, clipped glow and pattern repeats long before a straight edge does.
Use Outside when the composition already runs to the boundary. Use Inside when keeping the exact output dimensions matters more than keeping the outermost pixels.
Limits worth seeing before export
- A pale glow disappears on a pale page; preview it against the surface where it will be used.
- A glow cannot create separation when the subject and its own background already merge at the image edge.
Questions about the rendered frame
- Does the frame stay sharp on a large export?
- Yes. The frame is rebuilt as vector paths, gradients or procedural pattern tiles at the output dimensions. The screen preview is not stretched into the saved file.
- Can I change the opening colours?
- Yes. Every colour shown by the preset is a normal colour slot in the shelf. Width and any frame-specific strength, angle or scale controls remain editable too.
- Does the frame cover the photograph or add pixels around it?
- The Placement switch decides that. Inside draws the frame over the picture's outer edge and keeps the file's dimensions; Outside adds it around the picture and grows the canvas, so every pixel of the photograph stays in view.
