These work essentially the same – for Patch you draw around the area to be replaced, and for Clone Stamp, you first select an area to act as a source, then paint this over your lens flare. For smaller sized artifacts, this may be sufficient, but for larger instances of lens flare, you will then need to repeat this with the Patch tool and/or the Clone Stamp.Start with the Spot Healing Brush, making sure it is set to ‘Sample All Layers’ then paint it carefully over the lens flare.
To fix lens flare in Photoshop, where you only have one exposure and the lens flare is of the ‘Colors, Shapes, Artifacts’ type, your best bet is to use the Spot Healing Brush, Patch, or Clone Stamp, which act as the Photoshop remove lens flare tools. If you have already taken your picture and want to know how to remove lens flare from it, the best option is to use Photoshop or Lightroom (you could also use After Effects, Photoshop Elements, GIMP, Luminar, Affinity Photo, etc, broadly following the same steps below).
