Imperfect presets
Use this trick when you’re accumulating filter effects
Both the Radial and Graduated Filters will wipe out any existing Radial or Grad filters you may have previously applied when used in a preset. While it would be great for these to be cumulative, they’re not. The only way to work around this is to save each step you make as a new preset. So add a basic light leak, then save a preset. Add more, then save another new preset. To get variety, once you hit the 4 or 5 leaks stage, remove an earlier leak from the set and save that as a new Preset.
Yes, you’ll build up a lot of presets, but the joy is that when you run over the presets in the panel, you get a preview of what’s happening in the Navigator panel.
