Removing Objects From an Image - Nano Banana 2

Start by looking at what surrounds the object on all sides and naming the material that should continue through it. Grass, plain wall, sky, wood grain, carpet. If the object sits across a boundary — half on a table, half against a window — say both, and say where the boundary runs. That single sentence prevents the most common failure, which is a patch of plausible texture that ignores the line it should have continued.

Negative wording alone rarely works. Asking for “no dog” while the rest of the prompt still describes a park scene with a dog-shaped hole in the composition tends to produce a smaller dog, a different animal, or a dog-shaped smudge. Positive description of the replacement is what actually removes things.

Persistent reappearance usually means the composition still calls for it. If the object was the visual centre — the thing the framing pointed at, the reason for the arrangement of everything else — the model will keep filling that hole with something, because the picture is built around it. In that case the honest fix is to reframe rather than repair: crop the object out, or regenerate the scene without it in the first place.

The other recurring problem is repeated texture. Large removals against patterned surfaces produce visible tiling, the same knot of wood or clump of leaves stamped twice. Break the region into two or three smaller passes and describe each slightly differently, or accept the fill and then run one light pass over the whole area to vary it.
