    Reference image

    Also called Reference, Subject reference.

    A reference image is a picture supplied alongside the prompt so the model can copy an identity, product or style from it, without that picture becoming a frame of the output.

    The distinction from a starting image is worth being pedantic about, because they are different slots on the form. A starting image is the first frame — it appears, exactly as supplied. A reference never appears; it is a description made of pixels, and the model is free to show that subject from another angle, at another size, in different light.

    Models publish how many they will hold at once, and that ceiling is real. Beyond it, extra images are dropped rather than averaged in. Within it, variety helps: three angles of one product teach the model more than three near-identical crops.

    Everything in the frame is a reference, not just the part you meant. A subject photographed against a red sofa often brings the red sofa along, which is why cutouts and clean plates give more predictable results than snapshots.

    In practice

    • Different angles beat duplicates — you are describing a thing in the round.
    • Crop out what you do not want to inherit; the model cannot tell which part you meant.
    • Reference slots are separate from the prompt: the prompt still decides what happens in the shot.

    The mistake to avoid

    Using a heavily filtered or stylised photo as a product reference. The model learns the filter along with the product and applies both.
