Analyse de l'application GREYN pour le 6 septembre

Most retro apps stamp a picture of grain on top of your photo. GREYN doesn't have that picture. The grain, the halation glow around bright edges, the falloff at the corners — all of it is computed live on your device, at full resolution, every time you move a slider. That difference is the whole app. Because the texture is generated rather than pasted, it scales with your image instead of tiling across it, it reacts to the light in your frame instead of sitting on top of it, and it never repeats. Photos and video go through the exact same engine. What you see on a still is what you get on a clip. WHAT'S INSIDE • 129 film looks, each hand-built from a density curve rather than copied from a preset pack • 11 effects that stack: diffusion, flash, focus falloff, light leak, dust and scratches, tape lines, date stamp, colour bleed, prism, photocopy scan, duotone • 46 frames and borders — drawn as geometry, so they stay sharp at any size • 45 layouts, from contact sheets to photo-booth strips • 11 fine adjustments: exposure, brilliance, highlights, shadows, contrast, brightness, black point, saturation, vibrance, warmth, tint • Crop, straighten and rotate VIDEO, NOT JUST STILLS Pick a clip and it runs through the same shader as your photos — same look, same grain, same borders. Audio is preserved. Export up to 60 seconds. BUILT TO BE PRIVATE There is no account and no sign-in. There is no server. GREYN does not connect to the network at all. Your photos are read when you pick them, processed on your device, and written back only when you tap Save. Nothing is uploaded, nothing is collected, nothing is sold. One payment, then it is yours. No subscription, no in-app purchases, no ads.
