HDR-Pretrain: A Pretraining Dataset for 3D HDR Reconstruction
Paper | Code | Project page
HDR-Pretrain is a synthetic multi-view dataset for pretraining 3D high dynamic range (HDR) reconstruction models. It provides multi-exposure low dynamic range (LDR) images and corresponding HDR references to support learning 3D HDR scene representations from multi-view observations and rendering HDR images from novel viewpoints.
The dataset contains 168 Blender-rendered indoor scenes. Each… See the full description on the dataset page: https://huggingface.co/datasets/Bugjudger/HDR_Pretrain.HDR-NSFF

We present HDR-NSFF, a method for reconstructing dynamic 4D scenes with HDR video rendering from multi-exposure monocular video. Our approach extends Neural Scene Flow Fields… See the full description on the dataset page: https://huggingface.co/datasets/SHlNDY/HDR-NSFF.open-hdri-1k
Open HDRI 1K
A consolidated, public-domain (CC0-1.0) collection of 3,491 equirectangular HDR environment maps at 1K resolution, gathered from five free HDRI libraries: Poly Haven, BlenderKit, ambientCG, CGEES and Open HDRI.
Every map is stored as a linear, high-dynamic-range .exr file alongside a tonemapped .jpg preview, with a per-asset metadata row (dimensions, source, author, license, SHA-256 checksum and tags).

Krea 2 scene-linear HDR — LogC4 training dataset
320 scene-linear HDR training images for the Krea 2 HDR LoRA
(see model: LAXMAYDAY/krea2-scene-linear-hdr-lora
· tools: krea2-hdr-toolkit).
Built by re-projecting CC0 Poly Haven HDRIs into normal perspective scene images,
exposure-normalizing (mid-gray → 0.18), and LogC4-encoding to [0,1] so a wide
scene-linear range is carried through an ordinary 8-bit pipeline.
