The direct links to the pictures don't let you navigate away from them to other restricted pictures. If you want to toggle between pictures this link will take you to the album, https://picasaweb.google.com/FarrAnthony/ShadowBanding?authuser=0&authkey=Gv1sRgCPfPt66UxvTwvQE&feat=directlink .... then when you view a picture you'll have the navigation arrows available. Another lesson I've learned about Picasa. > I capture only with raw format, are you capturing JPEGs? That might be > the issue. > These are raw captures. The unedited picture is a straight conversion to jpeg by ACR and PSE8 with the parameters at default (not zero). My experience is that noise is better controlled when shooting jpeg, but the reduced exposure latitude and limited recovery potential inherent in jpeg means I almost never use them, unless an instant result out-of-the-camera is called for. I'm sorry, but this is the largest size I'll be uploading this picture. I know more pixels are better ;-) but the picture is from a private rehearsal and shouldn't be published.
