Convert gn to png

What is the difference between .gn and .png?

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.; A PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
