An HDR image (High Dynamic Range) is a high-definition image format created to capture a photographic scene in indredible detail. The format stores multiple exposures at different settings to capture the maximum amount of detail.

While most image formats are limited to 8 bits of data per colour channel, the HDR format supports 32 bits per channel, allowing a vast amount of image colour to be preserved using this format.

HDR images are aimed at professional users and can be opened in high-end image editing software such as Photoshop, which can also be used to convert to other, more portable formats such as JPEG.

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 minimizing 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 colours down to 256 or 16 colours to help reduce the file size of the PNG.
