Manual secondary flares are additional secondary flares that are individually added to the lens flare. These can be used in addition to, or in place of automatic secondary flares.
You use Manual secondary flares when you want to add unique flares that you don't want repeated.
You can have groups of secondary flares, instead of just one set. Many of the controls in this dialog are for a specific set of flares, not all sets.

To add another set to your flare, click the Add button beneath the On check box. To delete a set, click the Del button.
