FastPictureViewer is among the firsts of a new breed of hardware accelerated desktop applications and delivers unprecedented speed and ease of use.įreeware programs can be downloaded used free of charge and without any time limitations. The program has been translated into several languages, including Chinese, French, German, Italian, Japanese, Russian, and Spanish, and is able to browse folders and images who's names can be written in any language, thanks to its support for the Unicode standard. Standard image formats such as TIFF/MTIFF, JPEG, HD Photo, PNG, GIF, BMP, and ICO are supported. The software supports fast previewing of raw image formats such as Nikon NEF, Canon CR2, Panasonic RW2, Olympus ORF, and Adobe DNG through manufacturer-supplied or 3rd party image decoders. A tethering function is also available and works with all cameras fully compatible with the MTP/PTP transfer protocol, which includes most Nikon and recent Canon DSLRs. It displays shooting data (shutter speed, f-stop, ISO, exposure compensation) and RGB histogram in seamless floating windows and features a built-in program launcher, all in a slick and uncluttered user-interface. FastPictureViewer is an image viewer designed for photographers, helping to review digital photos faster than ever before.
