How can I adjust the size and intensity of a lens flare?

[Audrey Hossain]

I know there is a lens flare option in the filters section, but the option only allows me to modify the position of the flare, is there any way to modify the intensity and size of the flare?

- Create a black layer
- Add the lens flare on it
- Use Color-to-alpha to remove the black
- Scale and adjust opacity of the resulting layer
