FAQ
HDR to DDS Conversion
What are HDR files?
The HDR file format (.hdr) is a raster image format designed to store high dynamic range (HDR) data, capturing a wider range of brightness levels than standard formats like JPEG or PNG. Developed by Radiance, it uses a 32-bit floating-point representation per channel, enabling realistic lighting, shadows, and highlights.
What are DDS files?
DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications. DDS is a container file and can be decompressed using a graphics processing unit (GPU).
