Comment ça marche
Depth Anaglyph 3D estimates which parts of your photo are nearer or farther, builds slightly shifted left-eye and right-eye views from that depth, and combines them into one red-cyan image tuned to reduce ghosting through standard 3D glasses. The intensity control changes the real 3D separation instead of fading a ghosted copy over the image. At full strength, nearer surfaces shift by at most 1% and farther surfaces by at most 2% of the image width, and a narrow strip along the frame edges stays flat so nothing is doubled or clipped at the border. Framing and transparency stay the same, and the result is a lossless PNG.
