My comments on these codecs
Barb Bowman (http://digitalmediaphile.wordpress.com) has found a useful resource on this website http://www.fastpictureviewer.com/codecs/ for those of you who want to keep the Windows platform relevant to your high-end digital photography needs.
Here, this site provides downloadable codecs and plugins that work properly with the RAW image files that are part of high-end digital photography. Some of these codecs may work directly with Photoshop for Windows or simply become Explorer codecs for use in thumbnails and Windows Live Photo Gallery.
The main thing I have liked about this is that the codecs don’t cost anything and, from Barb Bowman’s experience, aren’t likely to bog your computer down. This may avoid the need to just use the Apple Mac for your digital-imaging needs.
