The RadLab Panel is installed automatically. To make it visible, select File -> Automate -> RadLab Panel from the Photoshop menu. The RadLab Panel will appear as a floating palette that you can collapse into a sing-button mini-panel.
Try moving the mini-panel to just under your Photoshop tools palette (that’s a very convenient place for it). You can select from several layering options, and launch RadLab with a single click from this panel. This is the only way to start with a blank recipe, and is the way we suggest you access RadLab.
