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.
