Stitching Spherical HDR Panoramas in NukeX with CaraVR
In this video we take an in-depth look at using the CaraVR toolset in NukeX 12.0+ for stitching spherical HDR panoramas. We talk about - Advantages of stitching in Nuke vs alternatives like PTGui and AutoPanoGiga - Blending multiple bracketed exposures into a single hdr image - Calibrating color and exposure - Using the C_CameraSolver node to solve our camera rig, including an in-depth rundown on creating manual feature matches, and a manual approach for getting a solve - Fixing alignment, ghosting and blending artifacts - Using C_SphericalTransform to paint out unwanted objects in frame - Using Blender, we'll test out our final HDR to see how it works!
