Is this an authentic instant-film frame?

It is a measured digital construction inspired by the familiar shape: narrow white edges and a lower writing area. It does not copy a branded film stock, rebate or print texture.

Why is the lower edge larger?

The lower margin creates the visual base and the area historically used for a note. Here it begins at 1.8 times the other edges and can be changed independently.

Does the photograph get cropped?

No. Grow mode adds pixels outside the existing frame. The photograph keeps its complete pixel grid and the exported canvas becomes larger.

Make a measured Polaroid-style photo border

The construction this opening uses

An instant-photo silhouette is a proportion problem before it is a styling problem. The side and upper margins need to read as one even frame, while the lower edge needs enough mass to form a base. This opening links the four edges, then applies a 1.8 lower-edge weight so one width control preserves that relationship.

Percentage units make the treatment scale with the photograph instead of becoming visibly thin on a large file or clumsy on a small one. At four per cent, a 3000-pixel long edge begins with 120-pixel side margins; the lower edge begins at 216 pixels.

Where the treatment stops working

A plain digital border cannot reproduce paper grain, chemical colour shifts, a film rebate or a cast shadow. Adding those here would turn a measured border into an illustration. This route is strongest when the clean silhouette is the intention and weakest when the desired result is a photorealistic print lying on a table.

The opening values are a starting construction, not a filter baked into the page. Every width, colour, unit and mode remains editable after the photograph opens, and the output readout states the dimensions before export. That makes the result reproducible instead of leaving its proportions hidden inside a decorative preset.
