Convert HDR to VDA

HDR stands for High Dynamic Range, and in the context of Radiance, it refers to a file format used for storing high-quality images. The Radiance HDR format was developed as part of the Radiance rendering system, which originated in the late 1980s at the Lawrence Berkeley National Laboratory. Its primary use is in the field of computer graphics, where it captures a wider range of luminance levels compared to standard formats, enabling more realistic lighting effects. This format is particularly beneficial for tasks requiring precise light measurements and accurate visualizations, making it indispensable for professionals in fields such as architectural visualization and visual effects.

The VDA file extension, associated with Truevision Advanced Raster Graphics Adapter (TARGA), is a raster graphics file format developed by Truevision Inc. It was designed for high-color and true-color display on IBM-compatible PCs, supporting resolutions matching NTSC and PAL video formats. VDA files are used for digital photos, textures, and video editing, offering various color depths (8 to 32 bits) and alpha channel transparency. The format includes both lossless and lossy compression options, ensuring high-quality image preservation.
