Why compare at 100%?

A larger image can look crisp when scaled down but reveal invented patterns and halos at actual pixels. Check the exact areas you care about, not just the whole image.

  • Inspect architectural lines, small type, fabric weave and tiny reflections.
  • Check whether edges are natural rather than oversharpened.
  • Compare equal crops aligned to the same source coordinates.

How this example should be documented

Every published case should include its original and output dimensions, the model version, selected mode, test date and a note about limitations. Only use rights-cleared source files.

Do not claim that 4× means four times as many total pixels: it multiplies width and height by four, so total pixels rise sixteenfold.
