HDRI Prep vs Exposure Check

Build a library of HDRI exposure brackets for your RICOH THETA V, Z1 or X, and fire them off on set in seconds. The THETA can shoot multi-exposure brackets, but setting them up in the official app is slow, and you can't save them to reuse later. HDRI Prep fixes that. Set up a bracket once, name it, file it under your show, and call it up whenever the lighting calls for it. BUILD BRACKETS THE WAY YOU THINK • Choose 3 to 19 photos, 1 to 3 stops apart. No need to set each exposure by hand. • Pick a center shutter speed, and the bracket spreads evenly above and below it. • Set aperture, ISO and color temperature for the whole bracket at once. Choices are limited to what your camera can actually do. ORGANIZED FOR PRODUCTION • Name brackets, group them by show, drag to reorder, and copy or move them between shows. • Each bracket is tinted by its color temperature, so tungsten and daylight setups stand out at a glance. ON SET • Live View, flat or as a 360° view you can drag around, to check the frame before you shoot. • A shot counter and timer while the bracket runs, and Cancel if you need to stop. • View the photos from that bracket the moment it finishes. • Browse the camera's photos, inspect them full screen or in 360°, share them to Photos, Files or AirDrop, or delete them from the camera. • Find nearby THETAs and join their Wi-Fi from the app. Cameras you've used are remembered. • Adjust the camera's shutter volume and sleep delay. TRY IT WITHOUT A CAMERA Demo Mode loads sample 360° brackets so you can explore every feature before you plug in a THETA. Works on iPhone, iPad and iPhone Duo, and includes a built-in Manual. GOOD TO KNOW • HDRI Prep connects over the camera's own Wi-Fi (the camera's access-point mode). • Shutter volume and sleep delay are saved to the camera itself, so they stay set even when HDRI Prep isn't running. • HDRI Prep focuses on bracketing. It isn't a replacement for the official THETA app, which works well alongside it. Built by a VFX artist for VFX artists. If "HDRI" and "THETA" mean something to you, this was made for you.

Exposure Check brings professional-grade exposure analysis to your iPhone, iPad, and Mac for 1 low price! False color imaging — used by cinematographers on set worldwide — reveals exactly where your highlights clip and shadows crush before it's too late. Use this tool to import images from Movies, TV Shows, and more to reveal how professional cinematographers exposed their final graded images. SHOOT IN APPLE LOG Capture with the in-app camera in Apple Log and read exposure the way you would on a pro monitor. Zone and False Color overlays follow the exact Apple Log curve, so every zone lines up with true scene stops — the full dynamic range of your sensor, measured in real light. REAL-TIME FALSE COLOR CAMERA See your scene through a live false color overlay as you shoot. Instantly identify overexposed highlights, underexposed shadows, and perfectly exposed midtones — the same tools used on professional film sets, now in your pocket. TAP TO METER Tap anywhere in the frame for an instant zone readout and a recommended f-stop. Simulate any lens aperture with the IRIS control and get a recommendation to place your subject at 18% middle gray — before you roll. ZONE SYSTEM ANALYSIS Exposure Check maps your image into distinct one-stop tonal zones so you can evaluate exposure with precision and intent. MANUAL CAMERA CONTROLS Take full control with manual ISO, shutter angle, white balance, frame rate, and lens selection — plus pinch-to-zoom lens switching and a live, draggable histogram. ANALYZE ANY PHOTO Import photos from your library and run Zone or False Color analysis instantly. The stacked compare view shows your original and analyzed image together so you can see exactly what the exposure is doing. ORGANIZE WITH PROJECTS Create projects to keep your shots organized.
