Our little application BeautyActionsFS is now up and available for FREE! at Adobe Exchange online store. BeautyActionsFS is a Photoshop Plug-in that allows you to do Frequency Separation of an RGB Image with a click of a button. It works for either 16 or 8 bit files. You can read all about it here. If you do this often in your workflow, this will save you time or the necessity of creating actions for each type of image.
