Remove Filter From Photo
A filter is a stack of adjustments, not a layer you can switch off
An app filter looks like a single effect and is really a short stack of them: a tone curve, a color split that sends shadows cool and highlights warm, a drop in contrast, a saturation shift, a soft glow, sometimes grain and a vignette. None of that is a separate object sitting on the picture, which is why an instruction to remove filter from photo cannot mean peeling something off. What it means is rebuilding the tone and color the file had before the grade was applied. The difficulty is that the stack was applied to a photograph, and parts of what it did cannot be inverted without a reference for how the scene actually looked.
