Raising contrast until the backdrop clips to pure white, which erases the edge information a clean cut-out depends on.

Contrast
Also called image contrast, tonal contrast or levels. Here is what it means, when it changes what you export, and what people get wrong.

The short answer
Contrast is the tonal separation between the light and dark parts of an image. High contrast means deep blacks sitting next to bright whites with fewer tones in between; low contrast means everything clusters in the middle and the picture looks flat and hazy.

The short version
Contrast at a glance
| Quick fact | Detail |
|---|---|
| Global contrast | Overall spread from darkest to brightest |
| Local contrast | Neighbouring-area separation, reads as sharpness |
| Best tool | Curves, for control over specific tonal ranges |
| Check with | The histogram, not your monitor |
| Irreversible risk | Clipped highlights and crushed shadows |

What is the difference between global and local contrast?
Global contrast is the spread of the whole image from its darkest point to its brightest. It is what the contrast slider and the end points of a Levels dialog control, and it decides whether a photograph feels punchy or washed out.
Local contrast is the separation between neighbouring areas at a smaller scale. Raising it is what clarity, structure and large-radius unsharp mask do, and the eye reads the result as sharpness even though no detail has been added and nothing is genuinely more resolved.
That distinction is worth knowing because local contrast is the more useful control for showing texture in fabric, grain in wood or brushed metal, while global contrast mostly changes mood.
What does clipping take away permanently?
Contrast works by stretching the tonal range, and once values hit either end they stop. Everything that was near white becomes exactly white; everything near black becomes exactly black. The difference between them is gone and no later edit brings it back, because there is nothing left in the file to recover.
For product photography, clipped highlights are the expensive kind. The edge of a pale item against a bright backdrop is exactly where the tonal information lives that a cut-out needs, and when it is blown to pure white the outline dissolves. Background removal then produces a ragged edge or eats into the product, and no amount of retouching restores an edge that was never recorded.
Watch the histogram rather than the picture. A spike jammed against either wall means values are piling up at the limit.
How much contrast does a listing photo want?
Enough to look clean on a bright page, and no more. Marketplace grids are rendered on white, which makes a flat image look grey and unappealing next to competitors, so a modest lift is usually justified. Past that point you start losing the fabric texture and shape information that persuades someone to buy.
A practical approach is to set the black and white points so the histogram just reaches both ends without stacking against them, then add local contrast only where the material deserves it. Curves give finer control than a single contrast slider, since you can lift the midtones without crushing the shadows. Do it on a 16-bit master if you have one, because heavy tonal stretching on an 8-bit file leaves banding in smooth backgrounds.
What people get wrong about contrast
Each one is a real failure mode, not a style preference.
Mistaking a local contrast boost for genuine sharpening, when it adds no detail and leaves halos around high-contrast edges.
Applying heavy contrast to an 8-bit JPEG rather than a 16-bit master, which shows up as banding in smooth gradients.
Editing contrast on a phone screen at full brightness, then finding the image looks muddy on a dimmer desktop display.
Questions people ask
Contrast, answered
The follow-up questions people search for once they have the definition.
Does adding contrast make an image look sharper?
Local contrast does, because the eye reads edge separation as sharpness. It is not real sharpening: no detail is recovered, and pushed too far it leaves visible halos along high-contrast edges. Global contrast changes mood rather than perceived detail.
Can I recover clipped highlights?
Not from a clipped JPEG, where the values are already at maximum and nothing distinguishes one blown pixel from the next. A RAW file sometimes holds recoverable data in one or two channels when only the third has clipped, but the reliable fix is exposing correctly at capture.
What is the difference between contrast and exposure?
Exposure shifts the whole image brighter or darker together. Contrast stretches it apart, pushing dark tones down and light tones up around a midpoint. You can have a correctly exposed image with almost no contrast, which is what a flat, hazy photograph is.
How much contrast should product photos have?
Enough that the image does not look grey against a white listing page, and no more. Set the black and white points so the histogram reaches both ends without piling up, then stop. Extra contrast costs you the texture detail that helps someone judge the item.

Neighbouring entries, so every term in the set is one hop from every other.
Cut-out
A cut-out is a photo with its background removed so the subject stands alone, ready to drop onto white, a colour or a new scene.
Compression ratio
Compression ratio is the size of the original image divided by the size of the compressed file, written as something like 10:1.
Depth of field
Depth of field is the zone of a photo that looks acceptably sharp, from the nearest point in focus to the furthest.
