A High Dynamic Range (HDR) file is a digital image format designed to capture and store a wider range of luminance and color information than standard image formats like JPEG or PNG. In photography and computer graphics, HDR files are used to represent scenes with extreme variations in brightness and contrast. They achieve this by combining multiple exposures of the same scene, each with different exposure settings, to create a single image that preserves details in both the brightest highlights and the darkest shadows.

HDR files typically have a greater bit depth, often 32 bits per channel, allowing them to represent a vast range of colors and tonal values. This extended dynamic range enables HDR images to closely mimic the way the human eye perceives light and color in the real world, resulting in more realistic and visually stunning images. HDR files can be created using specialized software or cameras capable of bracketing exposures, and they are often used in applications like professional photography, computer-generated imagery (CGI), and video production to achieve stunning visual effects and realistic lighting simulations.

To view or edit HDR files, dedicated software like Adobe Photoshop or specialized HDR software is often required. Once processed, HDR images can be converted to more common image formats like JPEG or TIFF for wider compatibility and distribution, but doing so may sacrifice some of the extended dynamic range that makes HDR images unique and visually appealing.

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimising the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colors down to 256 or 16 colors to help reduce the file size of the PNG.
