Greetings. I am a new forum member and Olympus DSLR (E-3, E-5) and PEN E-P2 user. My Olympus images can be found at my photo web site Steve Brantley Photography | SmugMug I 'd like to get some advice from Olympus Viewer 2 software users regarding your sharpness procedures and settings. When I double click a RAW or JPEG photo in the Browse window and it opens in the Image Edit screen, the right side of the screen shows an "Edit" tab as well as a "Raw" tab adjacent to it. Now within the "Edit" tab, there is a "Sharpness & Blur" feature, and below it is an "Unsharp Mask" feature. The adjacent "Raw" tab has its own "Sharpness" adjustment feature. Given these options, what do you do to add some sharpness to an JPEG image, as well as a RAW image? Do you utilize all of these choices, or some combination? This is quite confusing, and not explained to any extent in Viewer 2's on-line help. Also, considering the "Unsharp Mask" feature, what rule-of-thumb settings do you recommend for the Strength, Radius and Threshold sliders? Thanks for any and all comments.
