Take Out the Room, Keep the Shine

How it works

The photograph is scaled to about one and a fifth megapixels and repainted at 0.45 denoise, low because almost all of the frame should survive untouched.

The instruction names the targets specifically rather than asking for reflections to be removed: the photographer, the camera, the light stands, the softbox frames, the window, the room. Then it names what must stay, with a reason attached — every specular highlight, at the same brightness and softness, because those highlights describe the shape and the material.

The negative prompt is a list of what over-removal produces: a matte surface, lost highlights, dulled gloss, a flat plastic look, a changed material.

Two things made of the same light

Highlights and reflections are not different phenomena. Both are light that bounced off the surface without entering it, and on a perfectly smooth object both are images of whatever is in front of it.

What separates them in practice is structure and scale. A large diffuser two feet from a curved mug produces a broad, soft, featureless bright region — you cannot tell what it is an image of, and your eye reads it as glaze. A window across the room produces a small, sharp, rectangular patch with recognizable divisions in it, and your eye reads it as a window.

That is the line this workflow works along. Remove the parts that carry identifiable content, keep the parts that carry only brightness. It also explains why the job gets harder as a surface gets smoother: on chrome, everything is sharp and everything is identifiable, so there is very little anonymous shine to preserve and the removal becomes invention.

Fix it with a polariser, not a model

The strongest advice on this page is not to use this page.

A circular polarising filter cuts reflections from non-metallic surfaces optically, at capture, with no invention involved. A larger, closer diffuser turns a hard reflection into a soft one that reads as a highlight anyway. A sheet of black card opposite the product replaces the reflection of the room with a reflection of nothing, which is exactly what retouching is trying to fake afterwards.

These take minutes and cost less than a returns handling process. Retouching exists for the shots you already have, or for reflections that a polariser cannot touch — metal, principally, which is also where this workflow is weakest.

There is a general version of this rule across the whole catalog: the cheapest fix is upstream, and the further downstream you get, the more of the picture is invented.

What must not change

The line between retouching and misrepresentation sits inside this page, so it is worth stating where.

Removing the studio from a surface changes nothing about the product. A buyer who receives the mug gets the mug that was photographed, and the softbox was never part of it.

Changing the finish does change the product. If the cleanup leaves a satin glaze looking matte, or a brushed steel looking painted, the photograph now describes something the buyer will not receive, and that is a listing accuracy problem rather than a taste one.

So the check is the material, not the mess. Look at the result and ask what it is made of. If the answer changed, the retouch went too far, however clean it looks.

Publication gate

This page ships once the workflow has been run against a ceramic mug with a single softbox reflection, a chrome kettle showing a whole room, a glass bottle with reflections and refraction together, and a semi-gloss painted surface, with highlight brightness and softness measured against the source in every case.
