Overview:
This document presents the Dosch HDRI: Extreme Hires collection, a series of high-resolution HDRI (High Dynamic Range Imaging) environment maps designed for advanced 3D rendering and lighting applications. The collection includes multiple HDRI files identified by codes DH201 through DH224.

File Naming and Formats

The document details the naming conventions and file types used in the collection:

• Light-Probe Files: Examples include DH107LX.HDR, DH107LP.HDR, DH107LT.HDR.
• Light Probe Blurred: e.g., DH107LB.HDR.
• Spherical Maps: e.g., DH107SX.HDR, DH107SN.HDR.
• Vertical and Horizontal Cross Formats: DH107VC.HDR and DH107HC.HDR respectively.

Resolution Specifications

The HDRI images come in various resolutions tailored for different use cases:

• 4096 x 4096 pixels
• 2048 x 2048 pixels
• 512 x 512 pixels
• 6248 x 3124 pixels
• 2048 x 1024 pixels
• 6248 x 4686 pixels
• 4686 x 6248 pixels

These resolutions indicate the availability of extremely high-resolution environment maps suitable for detailed lighting and reflections in 3D scenes.

Collection Contents

The document lists the HDRI sets by their identification codes (DH201 to DH224), presumably representing different environment captures or lighting scenarios. Each code corresponds to a specific HDRI file or set within the collection.

Usage and Application

While explicit procedural or normative guidelines are not detailed, the document implies the HDRI files are intended for use in professional 3D rendering workflows, providing realistic lighting environments. The variety of formats and resolutions supports flexibility in integration with different rendering engines and software.

Summary of Critical Information

• HDRI Types: Light probes, blurred probes, spherical maps, vertical and horizontal cross formats.
• High Resolutions: Up to 6248 x 4686 pixels, enabling extreme detail.
• File Identification: Systematic naming with DH codes for easy reference.
