Short side
How big the image comes out. The small side is set to this and the rest follows. Smaller throws away more of the original detail. 512 is a good default, and 480, 720 and 1080 snap into place as you drag. Tap the number to type an exact size.
Dispersion
Pulls two tinted copies of the picture apart, so edges pick up colored fringes. Red and blue is the old cinema 3D look, but the two colors are yours to choose.
- Split
- how far apart the copies sit. 1 to 3 px reads as a slightly cheap lens, 10+ is openly a 3D poster
- Angle
- which way they separate. 0 is horizontal, like real anaglyph
- Strength
- how hard the fringe is mixed in. Above 100% it starts to glow
- Colors
- the two fringe tints. Complementary pairs (red/cyan, orange/blue) look like optics, clashing pairs look like a printing error
At 0 px nothing is touched, so your colors stay exactly as they were.
Chroma noise σ
Color static mixed into the color channels. This is the main “cheap re-saved JPEG” look. 0 is off, 20 to 30 reads as clearly compressed, 60+ is wrecked.
Chroma spot
How big each blob of that color static is.
- 1 px
- fine confetti, nearly vanishes if the image gets resized later
- 6–12 px
- blotchy, like a badly compressed JPEG, and survives resizing
- 25+
- big color patches, closer to a posterised photo
Spot shape
- Cells
- patches that tile the whole image, with hard edges. Closest to compression blocks
- Splat
- scattered clumps with clean gaps between them, more like speckle
UAP strength
Presses a fixed 8×8 pattern into the brightness, the same block grid JPEG works on. Higher makes that texture easier to see. 3 is subtle, 8+ is obvious.
Grain
- Color
- speckle drawn separately per channel, so it fizzes with color. Film-like
- Luma
- the same speckle in all three channels, so it stays brightness only and colors stay clean
- Saturation
- 1.00 leaves color alone, 0.00 gives black & white
Gaussian noise σ
Plain even noise laid over everything at the end. Use a little to soften how deliberate the rest looks.

Every stage is random, so the same settings give a slightly different result each time. Nudge any slider to roll it again.
