AnalogTV vs FaceDepth

AnalogTV recreates the complete analogue television chain - broadcast camera tube, composite signal encoding, RF transmission, and CRT phosphor display - simulated from physical first principles. Not a vintage filter. Not a post-process effect. A working simulation of every stage of broadcast television, from the camera neck to the phosphor screen. THE COMPLETE BROADCAST CHAIN. Not AI, Not a Filter, the Real Thing. Every frame passes through the same stages as a real television signal. A camera tube mode: Image Orthicon, Plumbicon, Vidicon, or CCD, captures the scene with its characteristic lag, halation, and MTF response. The signal is composite-encoded to NTSC, PAL, or SECAM standards, then decoded through the same mathematics a real television receiver performs. A Metal GPU fragment shader renders each frame onto a simulated CRT phosphor display at 60 fps. ANALOG CAM AnalogCam is a second way to use the app: a point and shoot camera with the console hidden and nine stompbox effect pedals along the bottom. Tap a pedal to latch it, hold it for a momentary hit. They are live while you record, so what you play is what is captured. EIGHT PHOSPHOR TYPES P22 colour television. P31 oscilloscope green. P45 white sub-millisecond. P4 B&W television. P3 amber radar. P7 dual-persistence radar — white flash fading to yellow-green afterglow. P11 deep blue photographic. P24 cyan-green flying-spot. Each calibrated from manufacturer datasheets and IEEE literature. Each shifts the IIR decay constants, rendered colour, and shutdown spot tint independently. SERVICE MENU Access the hidden service menu to make adjustments a television engineer would use: RGB drive and cutoff, convergence, focus voltage, G2 screen voltage, purity, HV regulation, and degauss. Every control operates at the physics level, changing focus changes the modelled electron beam diameter, not a software blur. TUBE AGEING AND SHUTDOWN Cathode emission falls with use. The screen accumulates burn-in at sustained high-brightness areas. Shut the set down and watch the EHT bleed, beam defocus, and phosphor decay to darkness with optional HV arc sounds. 14 TEST PATTERNS SMPTE and EIA colour bars, pluge, crosshatch, multiburst, zone plate, flat fields, and more. Every pattern is generated mathematically in real time. TECHNICAL SUMMARY - Metal GPU rendering at 60 fps - NTSC, PAL, and SECAM composite encoding and decoding - Eight phosphor types from primary source measurements - Four camera tube models with authentic lag and MTF physics - 14 test patterns generated in real time - Shadow mask magnetisation with 128×128 persistence texture - IIR phosphor decay with per-channel time constants - Aperture grille, shadow mask, and slot mask geometries Also on Apple TV as AnalogTV for TV, a separate app with a Teletext interface built for the Siri Remote.

FaceDepth turns your camera into a depth camera. Point it at a face and the shape of that face appears as a live, colour-mapped depth image — at around 30 frames a second, computed entirely on your iPhone. There is no server. There is no account. There is no upload. The neural network ships inside the app and runs on the device's own GPU, so FaceDepth works in aeroplane mode, in a basement, and on the day the internet is having a bad time. LIVE CAMERA • Real-time depth from every lens your iPhone has — front, ultra-wide, wide and telephoto • Face-priority autofocus keeps the subject sharp instead of the wall behind them • Capture stills or record video with the depth look baked in • Photos and videos save straight to your library with correct focal length, exposure and capture date • Grid, self-timer and flash, where the hardware supports it IMPORT AND PROCESS • Run any video or photo from your library, iCloud Drive or Files through the same model • Progress continues on the Lock Screen while you do something else • Output is written at full source resolution with the original audio intact CONTROLS Swipe the selector beside the shutter to reach every setting without leaving the viewfinder: • Seven colour maps — inferno, magma, turbo, viridis, plasma, bone and grey • Near and far clipping, to spend the whole colour range on the part of the scene you care about • Gamma, for how sharply depth falls off • Range and depth smoothing, to trade temporal stability against motion blur • Invert, and a side-by-side view showing the source next to its depth BUILT FOR THE HARDWARE FaceDepth measures your device rather than assuming. A setting times the model across CPU, GPU and Neural Engine and picks whichever is genuinely fastest on your iPhone — which is not always the one you would expect. The camera also asks for exactly the frame rate the pipeline can sustain, so it does not waste power capturing frames it would only throw away. PRIVACY FaceDepth collects nothing. No analytics, no crash telemetry, no advertising identifier, no accounts. Camera and microphone access are used only to produce the image and video you are looking at. Photo library access is used only to read the file you choose and to save the result you asked for. Requires iOS 26.
