Calibration Flow vs Demosaic

Calibration Flow is the tonal calibration tool for silver-based and alternative photographic processes: cyanotype, platinum-palladium, gum bichromate (Aquaprint), carbon, Van Dyke, resinotype. KEY FEATURES • Custom calibration curves per process, paper and negative • Pre-calibration sheet: 9 variants around a central reference, with a correction curve applied first and increments of 5, 10 or 25; larger photos, targets and grayscale ramps help compare settings. • Digital negative: high-resolution generation and export (300 to 720 dpi, continuous tones or halftones) • Direct printing: send the negative to your printer from the app, with no AirPrint and no third-party app — it asks the machine what it can do before sending, honors its hardware margins, and follows the job • CMYK tonal separation with black generation control (GCR), including multi-zone • Full Gamut color mode with 5, 6 and 7 channels (Orange, Green, Violet), to go beyond simple CMYK • Ink steps: set where each ink stops, in negative as well as positive, combinable with zones • Screen angles: one angle per ink (rosette) or all aligned • Color Venn: printing test target and ink-layer overlay simulator, with eyedropper and magnifier • .acv export for Photoshop, Lightroom, Affinity Photo and GIMP • Registration marks: a frame of targets around the image and a mini-target that follows the output, in negative as well as positive • Harmonic exposure timer with circular dial, multi-device sync, and Dynamic Island / Live Activity on iPhone • Bluetooth control for compatible UV lamps (BanlanX SP630E controller) — on/off control from the app, no variable-intensity dimming • HD media library with cloud sync and multi-device access • Large-format tiling: edge-to-edge A4, A3 and A3+ sheet assembly PRO SUBSCRIPTION Calibration Flow is free with: – 3 cloud-synced calibration curves – 300 MB of cloud storage – Unlimited presets – CMYK tonal separation (4 inks) The Pro subscription unlocks: – Unlimited calibration curves – 5 GB of cloud storage – .acv export (Photoshop) – Color mode with extended inks (5 to 7) – Advanced separation settings: black generation, fine tuning Two plans: €9.90/month, or €99/year (equivalent to €8.25/month, effectively 2 months free).

Demosaic is a local RAW and image editor for iPhone and iPad. Built around a direct photographic workflow, Demosaic supports both RAW and standard image editing, including: • Exposure, brightness, contrast, and saturation • Tone curves and RGB curves • Highlight recovery and shadow adjustment • Sharpening, denoise, local contrast, and dehaze • White balance and color tools • HSV equalizer and channel mixer • Crop, rotation, perspective, and lens correction • High bit-depth export and wide-gamut workflows For RAW files, Demosaic also provides lower-level sensor and reconstruction tools, including: • Demosaicing controls • RAW black level adjustment • False color suppression • Chromatic aberration correction • Input sharpening • Hot and dead pixel cleanup Supported color spaces include: • sRGB • Display P3 • Adobe RGB • ProPhoto RGB • Rec.2020 All editing is performed locally on-device. Performance Note: Some RAW workflows, including denoise, local tone mapping, and high-quality export, can be demanding on CPU and memory. For a more stable experience, M-series iPads or devices with A17 Pro and newer chips are recommended.
