How it works
Near–Far Split Tone estimates relative—not measured—depth, normalises it from the 2nd to 98th percentile, and removes isolated speckles with a 3 × 3 median filter. It applies disjoint cool-far and warm-near color shifts in OKLab around a source-exact neutral middle band. Intensity directly scales the perceptual a/b color shift; lightness is not deliberately changed, and source-relative gamut compression restrains saturated pixels before they create new clipped RGB channels. At its working size, every output pixel uses only same-coordinate source RGB: no image content is moved, copied, spatially resampled, inpainted, or regenerated, framing stays fixed, and working-frame alpha stays byte-exact in the lossless PNG. Larger uploads can be proportionally resized first: the standard free limit is 800 pixels on the long side, and the depth service defaults to a 2048-pixel long side for remaining larger inputs.
