Portable Document Format File

The .pdf file format extension was developed by Adobe systems in 1993 as a means of presenting documents in a consistent manner across different platforms, hardware, operating systems, and applications. The format was not released as an open source document format until 2008, though minimal proprietary technologies still controlled by Adobe Systems exist in the format. Every .pdf document carries with it the necessary meta information required to properly reconstruct the text, fonts, and graphics used to produce the document. This ensures that documents will be viewed in exactly the same way the author intended regardless of the device used to open the document. From conception to date, Adobe Systems has continued to support the format adding features with every iteration of the standard including hardened algorithms for document encryption and privacy. Today, many freely available readers exist allowing you to open and view .pdf documents and create or convert other file formats such as .jpeg and .doc into .pdf documents.
HDR

High Dynamic Range Image File

A .hdr extension file is a High Dynamic Range image format that is also known as HDRI or a Radiance HDR format. A raster image or a digital photo with dark shadows or washed out areas can be rectified using HDRsoft to enhance the color and improve the brightness level. The Multiple pictures having different exposures can also be combined to create one image with an even distribution of color with the HDR software. As compared to standard digital imaging or photographic techniques, HDR imaging uses a high technology to improve the picture quality of an image by increasing its clarity, brightness and luminosity.
