10月9日的720nm应用程序分析

720nm is a fast, native infrared photo editor for iPhone and iPad. Built for photographers shooting on IR-converted or IR-filtered cameras who want a real editing workflow without opening a laptop. Everything you need for IR, done right: • Channel swap - one tap for the classic red/blue "blue sky" IR conversion, plus full manual RGB channel mixing when you want control. • Tap white balance - sample foliage or any reference point to neutralize the deep color cast instantly, with manual temperature and tint too. • Dramatic B&W - a channel-weighted mixer built for high-contrast infrared black & white, not a flat desaturate. • Hot-spot correction - automatically reduce the bright center hot spot common with IR lenses, then clean up residue by hand with the brush (Apple Pencil supported on iPad). • Tone controls - contrast, clarity, and sharpening tuned for flat, soft IR captures. • RAW in, high-quality out - open your RAW files; export JPEG, 10-bit HEIC, or 16-bit TIFF for a lossless desktop round-trip. Non-destructive, always. Your edits are a live stack - the original pixels are never touched until you export. EXIF, orientation, and color space survive the round-trip. Fast where it counts. Real-time preview on channel and tone operations, so editing never lags. On iPad, the larger canvas and Apple Pencil make manual hot-spot touch-up precise. Honest, simple pricing. One price to download. Every feature unlocked from the first launch. No trial, no subscriptions, no in-app purchases, no per-feature paywalls, no tracking.
