FastRawViewer opens, as the name implies, RAW files extremely fast and direct, rather than displaying an embedded JPEG preview like most RAW viewers. Instead, images are rendered directly from the RAW files, so you can use the RAW histogram to see the really unaffected image. This makes FastRawViewer the ultimate photo culling tool.
FastRawViewer is for viewing images only and does not change them at all. It is available as a free 30-day trial. Then it's a one-time payment of $ 25 if you continue to use it.
