Particle Generator vs Phosphor Press

Particle Generator is an interactive particle visualizer with a video capturing option. You can create your own custom particle visual effects and record them in video mode. Lastly, you can use the video for creative purposes. Features: • 9 particle textures available for selection • Ability to set a custom texture by loading an image from the library • Touch to set particle emission position • Adjustable particle emitter options: Position, Angle, Speed, Alpha, Scale, and Rotation • Ability to set particle color gradient • Ability to set background color • Save/load particle presets • Save particle effect snapshots to the camera roll • Save particle effect videos to the camera roll Particle Settings Quick Explanation Emitter Birthrate = [100] particles born per second Maximum = [0] is infinite. If set to a specific number, e.g., [1000], particles will stop once the limit is reached Lifetime Start = [20] each particle lives for [20] seconds before disappearing Range = [5] each particle lives for 20 ± [5] seconds Position Range X = [80] particle birth range in width Y = [80] particle birth range in height Angle Start = [0] particle starting angle in degrees Range = [60] particle starts at 0 ± [60] degrees Speed Start = [50] moves at [50] velocity Range = [10] moves at 50 ± [10] velocity Acceleration X = [0] negative for acceleration to the left, positive for right Y = [0] negative for acceleration downward, positive for upward Alpha Start = [0.5] initial alpha value ([0] = transparent, [1] = opaque) Range = [0.3] alpha range: 0.5 ± [0.3] Speed = [-0.05] animates particle transparency (negative = more transparent, positive = more opaque) Scale Start = [0.5] initial scale Range = [0.2] scale range: 0.5 ± [0.2] Speed = [-0.05] animates particle size (negative = smaller, positive = larger) Rotation Start = [30.0] starting rotation angle in degrees Range = [120.0] rotation range: 30 ± [120] degrees Speed = [-0.02] animates rotation (negative = clockwise, positive = counterclockwise) Create distinctive, beautiful particle effects with plenty of customization options. You can create rain effects, fireworks, or any abstract art effect and enjoy the colorful particle show. This particle show brings joy and a cheerful atmosphere to your device.

Phosphor Press turns a photograph into the kind of picture a machine would have shown you before it could show everything: a few tones, a visible grain, and hard pixel edges. Not a filter laid over your photo. The picture is taken apart and rebuilt on a palette of two, four or sixteen colours, with the dithering that made those palettes bearable in the first place. SCREENS AND PRINT Paper — dark ink on warm paper, four tones. The one to start with. Ink — the same, at two tones, for a woodcut edge. Amber and Green Terminal — the monochrome monitors, at two levels or four. Inked 256 — full colour under hard black outlines. CGA 1984, CGA Outline, EGA Adventure — the hardware palettes, matched in a perceptual colour space so four colours still look deliberate. Mosaic — your photo's own colours in big square blocks. CONTROLS THAT DO SOMETHING Pixel size, from a coarse mosaic to a fine grain. Period screen modes keep their original non-square pixels, so 320x200 looks the way it did on a real monitor. Outlines that follow shapes rather than brightness. The app segments the picture into regions and draws the boundaries between them, so a line closes around an object instead of breaking up wherever contrast dips. Even lighting, which divides out the light in a scene so a surface split by a shadow stays one colour instead of becoming two objects. Auto levels, contrast, saturation, flattening, and frame shapes from square to 16:9 with a manual crop. WHAT IT IS GOOD AT Strong shapes and clear contrast: architecture, landscapes, silhouettes, objects against a plain background, anything backlit. A photograph reduced to four tones keeps what a silhouette is made of. It is honest about the rest. Fine texture — hair, foliage close up, crowds — is what these palettes have to throw away, and portraits are the hardest subject of all. Monochrome handles them better than the colour palettes do. NOTHING LEAVES YOUR DEVICE No accounts, no analytics, no advertising, no server. The app works with the network switched off entirely. Your photos are read, converted and shown back to you, and they go somewhere else only when you save or share them yourself. FREE, AND PRO Every palette, every dither mode and every frame size are free, forever. Phosphor Press Pro is a single one-time purchase. It removes the signature from exports, adds CRT effects — scanlines, phosphor glow, aperture grille, vignette — adaptive palettes picked from your own photo, exports up to eight times the pixel size, and your own saved presets, exportable to another device.
