Using a dark background works best in this case. So I used black as the background. Select the ‘Pen Tool (P)’ and up on the ‘Options Bar’, select the ‘Paths’ option.(Second one)
Using this Option will not create a new layer, so it’s best to do that now.
Then click (Start Here) and continue to add ‘Anchor Points’ (in the direction I have indicated with the arrows below) (Ultimately the Path Shape is up to you!)
Select the ‘Brush Tool (B)’ on the Toolbar, and up on the ‘Options Bar’ select the ‘Brush Preset Picker’ and from the list choose a soft edge brush. I chose a brush tip of 2.
Hit the ‘X’ key on the keyboard to set the foreground color to White.
Then from the drop down options, choose ‘Stroke Path’
Then from the Tool: options select ‘Brush’
Nothing fancy, but combined with other elements it can really enhance an image.
