DollyCam: Cinematic Filming

DollyCam turns your iPhone into a one-person dolly zoom rig. The app tracks a face in real time and adjusts zoom as you walk toward or away from your subject, recreating the Vertigo effect made famous by Hitchcock -- no rail, no crew, no post-production.

DOLLY ZOOM
Tap a face, pick a direction, and press record. The app handles the rest:
- Walk Away: zoom increases as you move back, keeping the subject the same size while the background stretches
- Walk Toward: zoom decreases as you approach, compressing the background behind the subject
- Adjustable zoom response and intensity sliders let you dial in the exact look
- Noise rejection and frame smoothing eliminate jitter from handheld movement
- Monotonic ratchet prevents zoom reversal during recording for a clean, one-direction push

DUAL CAMERA (PiP)
Record from front and back cameras simultaneously:
- Floating picture-in-picture window you can drag anywhere on screen
- Drag to the top or bottom edge for a 50/50 split-screen layout
- Combined mode composites both feeds into a single video file
- Separate mode saves two synchronized files -- one from each camera

MULTI-ASPECT RECORDING
Capture portrait and landscape from a single take:
- Records 9:16 portrait and 16:9 landscape simultaneously
- Uses the ultra-wide camera for the landscape crop
- Both files receive the same LUT and stabilization settings
- Perfect for repurposing content across Reels, TikTok, and YouTube

CINEMATIC EXPOSURE LOCK
Lock the shutter to a 180-degree shutter angle at 24 or 30 fps for true film-look motion blur:
- Auto ISO adapts to changing light while shutter speed stays fixed
- Live ISO readout on screen
- Low-light and overexposure warnings so you never clip

COLOR GRADING WITH LUTs
Apply .cube LUTs in real time -- on the preview and baked into the recording:
- 10 built-in looks: Cinema Teal, Nostalgic, Monochrome, Vivid, Warm Fade, and more
- Import your own .cube files from any source
- Intensity slider blends from 0% to 100%
- GPU-accelerated Metal rendering pipeline with trilinear interpolation
