Easily Export Presets
Once u've started processing a certain image under the Develop module and want 2 apply the same values to other images in the future, u can save the preset by clicking on the Presets panel on the left. Clicking on the "+" sign will open up a window asking u to enter a name 4 the preset. This newly-saved preset and all other presets will be saved in \Documents and Settings\YourUsername\Application Data\Adobe\Lightroom\Develop Presets. Simliarly, the settings 4 some of the other features r saved in \Documents and Settings\YourUsername\Application Data\Adobe\Lightroom. You can move these to another machine for later use.
