RGF to HDR conversion is the process of transforming an image stored in the RGF (Raster Graphic Format) into an HDR (High Dynamic Range) image file. This conversion extracts the original raster pixel data and remaps color and luminance information into an HDR container so images retain extended brightness range and greater detail in highlights and shadows.

The RGF file format uses a specific MIME type often linked to raw image data, while HDR files use the image/vnd.radiance MIME type. RGF is commonly used for raw graphic data requiring specialized codecs, whereas HDR is a high dynamic range image format supported by many image processing codecs. HDR files are ideal for applications needing enhanced color and lighting details.
The HDR (.HDR) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like RGF.
While specific technical details aren't available here, HDR files generally serve the purpose of storing image effectively within their domain.

RGF files typically store raw image data with limited compatibility, whereas HDR files support a wider color range and are widely used for high-dynamic-range imaging. While RGF is often proprietary or specialized, HDR files are standardized and supported across many platforms and applications, making HDR the preferred choice for advanced image work.
Keep source RGF files under 50–200 MB for faster conversions; very large images with many layers can slow processing significantly.
Preserve quality by choosing a 32-bit float HDR output (OpenEXR) rather than 16-bit or lossy Radiance exports when dynamic range matters.
For batch conversion, prepare RGF files with consistent color profiles and dimensions to avoid extra per-file adjustments.
Be aware RGF-specific features like proprietary metadata or uncommon compression may not carry over; flatten layers or export a standard raster if important.
