Applying a large feather to hide a bad selection, which turns a hard error into a soft, translucent one.

Feathering
Also called feather edge, soft edge or edge softening. Here is what it means, when it changes what you export, and what people get wrong.

The short answer
Feathering softens the edge of a selection or mask so it fades out over a few pixels instead of stopping dead. It keeps a cut-out from looking stamped on, because real photographic edges are never perfectly sharp: lens blur and anti-aliasing always leave a thin transition.

The short version
Feathering at a glance
| Quick fact | Detail |
|---|---|
| Applies to | Selections and masks, not the pixels themselves |
| Measured in | Pixels, so it scales with image size |
| Typical product cut-out | Roughly 0.5 to 1 px |
| Fixes | Jagged, stamped-on edges |
| Does not fix | Colour halos or a mask cut too wide |

How much feather does an edge actually need?
Less than most people expect. The aim is to match the softness that the camera already produced, not to blur the boundary. As a rough working guide for product cut-outs:
- Small web images, under about 1000 px on the long side: around half a pixel.
- Standard listing images, roughly 1500 to 2500 px: half a pixel to one pixel.
- Large or print-sized files, 3000 px and up: one to two pixels.
- Genuinely soft subjects, such as a shadow edge or an out-of-focus limb: considerably more, matched by eye.
Feather is measured in pixels, so the same setting behaves very differently on a thumbnail and a 6000 px master. Always judge it at 100 per cent zoom, and against the background the image will actually sit on rather than against white.
What goes wrong when you feather too much or too little?
Too little and the outline reads as a hard line. On curves and diagonals you get visible stair-stepping, and against a contrasting new background the subject looks like a sticker.
Too much and the edge turns mushy. The subject appears to dissolve into the backdrop, thin details such as handles and straps thin out or vanish, and a translucent rim lets the new background bleed inward. Over-feathering is particularly damaging on text, logos and straight product edges, where any softness is immediately obvious.
Is feathering the same as blurring the edge?
At the mask level, effectively yes: feathering blurs the mask rather than the image, so the visibility fades gradually while the underlying pixels stay sharp. That is why it looks natural and a blur applied to the photo itself does not.
It is worth separating feathering from two neighbours. Contracting (also called choking) pulls the whole edge inward by a set number of pixels and is what removes a rim of leftover background. Decontamination replaces the colour of edge pixels with colour sampled from the subject. Feathering does neither. If a cut-out has a pale halo, more feather will only spread it, so contract and decontaminate first, then feather.
What people get wrong about feathering
Each one is a real failure mode, not a style preference.
Using the same feather radius on a 600 px thumbnail and a 5000 px master, since the setting is absolute rather than proportional.
Judging the feather against a white canvas when the image is destined for a dark background, where every soft pixel shows.
Feathering a logo or straight-edged packaging, where any softness reads immediately as a mistake.
Questions people ask
Feathering, answered
The follow-up questions people search for once they have the definition.
What feather radius should I use for a product photo?
Start around half a pixel to one pixel on a typical 2000 px listing image and check at full zoom. Hard-edged goods want the lower end. If the original shot has a shallow depth of field, match the softness you can already see at the edge instead.
Can I feather after I have already exported the file?
Not properly. Once the image is flattened, the edge pixels are mixed with whatever background they were composited onto, so softening them further just smears that colour outward. Feather while you still have the mask or the layered document.
Why does my cut-out still look fake after feathering?
Feathering only addresses hardness. If the subject still looks pasted on, the likely causes are a leftover colour fringe, a missing contact shadow, or lighting on the subject that does not match the new background. Those need separate fixes.
