Kelvin Camera turns your iPhone into a fully manual camera. Every control a DSLR gives you — ISO, shutter speed, focus, white balance, exposure compensation — on dials designed for one-handed shooting. No AI enhancement, no over-processing: the photo you take is the photo you get. MANUAL EVERYTHING - Full Auto, ISO Priority, Shutter Priority or full Manual exposure - ISO and shutter speed on haptic ruler dials with live readouts - Three focus modes: AF-C, AF-L (tap to lock) and Manual with focus peaking - White balance in Kelvin plus Daylight, Cloudy, Shade, Tungsten and Fluorescent presets - Exposure compensation in 1/3 stops with a thumb-friendly stepper - One tap back to Auto for any control, any time FILM, DONE PROPERLY Nine film simulations built as real color profiles — temperature, tone curve and per-channel response, not a slapped-on filter. Live in the viewfinder, so you see the look before you shoot. Add monochromatic grain in four strengths, rendered per pixel. LONG EXPOSURE, YOUR WAY Pick any duration from 1 to 10 seconds. Silky water, light trails and motion blur — with a live progress bar while you hold steady. PRO CAPTURE - Apple ProRAW and RAW (DNG), paired with processed photos - HEIF for everyday shooting, JPEG for compatibility, lossless TIFF for archival - All lenses with true focal length labels, precise zoom, tap-to-focus and exposure - Fill light with five power steps, front-camera screen flash - Hardware shutter: volume keys and Camera Control - Full EXIF in every photo, including optional GPS location SEE YOUR EXPOSURE - Live RGB histogram while you compose - Rule-of-thirds grid, horizon level and focus peaking overlays - Your latest photo one tap away, your settings exactly where you left them TRY EVERYTHING FIRST The whole app is free to explore — every dial, every film, every mode, live in the viewfinder. Unlock the shutter with Kelvin Pro: $4.99/month or $29.99/year, both with a 7-day free trial, or $39.99 once for lifetime access. Subscriptions are charged to your Apple ID account, renew automatically unless cancelled at least 24 hours before the period ends, and can be managed in Settings → Apple ID → Subscriptions.

StreamCamera turns two Apple devices into a camera and a monitor. One device films. The other shows the picture live and can record it at the same time. HOW IT WORKS • Open StreamCamera on both devices, pick the other device in Nearby Devices, and accept the request. • iPhone or iPad to Mac: connect over a USB cable for the steadiest picture, or over Wi-Fi. • iPhone to iPad, or two of either: over Wi-Fi. • The monitor shows the quality actually arriving, so you always know what you are watching. ON THE MONITOR • A live view of the camera's picture, up to 4K30 over a cable. • Record the stream on the monitor as a second copy of the take. • Take a photo of the live picture. • Start and stop the camera's recording from the monitor. CAMERA CONTROLS • Auto mode, or take over with ISO, shutter, white balance and exposure. • Face retouch and eye size, adjusted live with a fine slider. • Tap to focus, with an exposure slider at the focus point. • White balance presets and per-lens ranges that match your device. • Switch lenses, zoom, and change frame rate and resolution. • Your resolution, frame rate, codec and colour profile are kept when you change lens and between launches. RECORDING • Record in HEVC, H.264 or ProRes 422 LT, 422 and HQ. • Pause and resume a take without starting a new file. • See how much recording time your free space allows. • Name your files with your own prefix and suffix. • Dim the screen while recording to stay cooler and save battery. DUAL CAMERA • Record the front and back cameras at once on supported devices. • Save both in one video, or as a separate file for each camera. • Move the inset picture where you want it. FRAMING TOOLS • A level guide: a horizon line when you shoot straight ahead, and two marks that meet when the device is flat over a table. • A grid, and framing guides for common aspect ratios. • Stereo audio meters while you film. YOUR MEDIA • Everything you record is saved to your photo library. • Browse, play, share and delete your takes inside the app. • Drag across the grid to select several files at once. LANGUAGES English, French, German, Spanish, Persian, Arabic, Indonesian, Japanese and Simplified Chinese. STREAMCAMERA PRO Without Pro you can stream for 1 minute at a time, or 30 seconds while a recording is also running, and recordings are 30 seconds. Pro removes those limits and unlocks Dual Camera, splitting long recordings into clips automatically, and recording both cameras combined or as separate files. Choose the plan that suits you: 1 month or 1 year, or buy Lifetime once with no subscription. • Payment is charged to your Apple Account at confirmation of purchase. • A subscription renews automatically unless it is turned off at least 24 hours before the end of the current period. • Your Apple Account is charged for renewal within 24 hours before the end of the current period. • Manage or cancel your subscription in your Apple Account settings after purchase. • Lifetime is a one-time purchase and never renews. GOOD TO KNOW • Both devices need StreamCamera. For Wi-Fi, put them on the same network; a 5 GHz or Wi-Fi 6 network gives the best results. • While the camera records in HEVC or H.264, the monitor picture switches to a lighter format so it stays smooth. Your recording always keeps the quality you chose. • On Mac, StreamCamera is for monitoring and recording a stream; it does not use the Mac's own camera. • At 4K, Face Retouch and Eye Size record at 30 fps so the frame rate stays steady. Other resolutions are unaffected. Privacy Policy: https://arthousestudio.net/products/streamcamera/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
