Applying iPhoto effects in batch!
Batch processing can really speed things up and it is the main reason why applications such as Automator are so great. iPhoto doesn't have any kind of batch processing capabilities, especially when it comes to editing photos. Being able to apply effects such as Enhance, Black and White, Sepia, etc, to a bunch of photos at once could be really helpful. There is a free third-party application that solves this. It is not a plugin, but a standalone application. To use it, you simply select the photos in iPhoto and switch to the application called iPhoto Batch Enhancer. You choose the settings in the app and click "Apply". You can download iPhoto Batch Enhancer here from MacUpdate.
