Saving Your Work

You can make numerous changes to your files using the Factor Files worksheet approach. Form a workflow perspective, you could make several changes and then click the Apply Changes and Refresh button, then continue working with additional changes. Or, you might make all the changes at once and then apply. Regardless, your changes ARE NOT saved outside of Photometric Power Tools until you elect to do so from the File menu selections in the Viewer/Editor dialog
