Adobe has released Lightroom 4.3 with support for 20 cameras and 42 lens profiles (including the iPhone 5) and fixes for a variety of bugs. Amongst the highlights, the professional photo cataloging and editing application fixes a problem with uploading to Flickr if the photo’s filename contained an apostrophe, ensures that Catalogs from Photoshop Elements 11 are updated, properly imports AVCHD video, fixes an issue where TIFF images could experience a tonal shift, and fixes a flickering problem with videos created on the iPhone 4. Additionally, Lightroom 4.3 now supports Retina displays when using either the Library or Develop modules. ($149 new, free update, 419 MB, release notes)
Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
