The Apollo HDRU (High Dynamic Range Image) file type, with the extension .hdru, is a specific format used for storing high dynamic range (HDR) images. These files are designed to capture a broader range of brightness and color levels than standard digital imaging formats, allowing for more detailed and realistic representations of scenes with significant contrasts in lighting. The Apollo HDRU format is particularly used within the realm of digital photography, computer graphics, and advanced imaging applications where capturing the fullest possible range of light information is crucial. This format helps in preserving the quality of images for professional editing, rendering, and display purposes, ensuring that details in both the brightest and darkest areas of a photo are maintained.
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.
