To remove metadata, choose the + button in the ModifyMetaData# node properties panel; a placeholder will be created in the metadata box. Next, double-click on the cell under action to display a flyout and then choose remove from the flyout. Invoke the Pick Metadata key dialog box as discussed earlier. Select the keys to be removed from the dialog box and then choose the OK button; the selected key will be removed from the metadata. To cancel an existing action choose the - (minus) button from the ModifyMetaData node properties panel.
Note: When you delete a key from the metadata, it only affects the ModifyMetaData node calculations. It does not alter the embedded metadata in the input images.
