- Description
- The GN file type, associated with Apollo HDRU (High Dynamic Range Utility), is a proprietary format used for storing and processing high dynamic range images. These files are specifically designed to retain a wide range of luminosity levels, allowing for more detailed and realistic representations of scenes with significant contrasts in brightness. The Apollo HDRU software leverages the GN format to enable advanced editing, tone mapping, and rendering capabilities that enhance the visual quality of images without losing detail in both shadow and light areas. This makes GN files particularly valuable for professional photographers, graphic designers, and any visual media creators seeking to achieve the highest quality in digital imaging.
- Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
