iPhone

Fourteen plates, every part of the look under a slider, exported at your exact screen resolution. No photos, no filters. The image is generated. Emulsion makes the grainy, near-black gradient images that fill phone wallpaper feeds: soft lit forms, folded satin, liquid chrome, light shafts. Every part of the look sits under a slider. There is no photo input and no library of textures. One shader draws the whole image, evaluated per pixel at the exact resolution you export, so a wallpaper is not a stretched preview. It is the same math, sampled more finely. FOURTEEN PLATES Each plate sets a complete look (form, optics, tone, colour and grain), and each carries its own colour ramp, so no two land in the same place. Pick one as a starting point, then take it anywhere. EVERY PART UNDER A SLIDER Eight field shapes, from a lit column to folded waves to warped chrome contours. Resolution-independent blur and directional streak. Exposure, black point, gamma, contrast, gloss and vignette. A three-stop colour ramp with a movable midpoint and fifteen palettes. Grain sized in real output pixels, with density and midtone bias. Optional dash, brush, weave or halftone overlays. BUILT FOR YOUR SCREEN Output presets for current iPhones, or any custom size. Lock screen guides show where the clock and widgets will sit before you save. Save straight to Photos, share, or export a set of seed variations at once. SEAMLESS LOOPS Animate the field and record one full cycle as video. The motion returns to frame one exactly, so loops are seamless by construction rather than by crossfade. Emulsion runs entirely on your device. Nothing you make is uploaded, and the app collects no data at all.
