I'd like to be able to 'draw' more of the trail that can be seen in the above picture in between the two trees. I'm doing data augmentation for ML, so I want to have the same features but maybe add another one in a different direction for example, with a loop etc...

Is there some sort of tool (something similar to the eyedropper), where I could have a pen that would draw this?

I would create a custom brush for this. Using a small part of the image, adjust the curves to create more contrast, and convert to black and white, erase any extraneous pixels. Define this as a brush. And apply settings similar to those shown below.

Back in your image, select a suitable foreground colour, set the brush size accordingly, and paint with the brush.

    Thanks @BillyKerr this is exactly what I needed! I've been trying to do the custom brush but I'm struggling to get it anywhere as good as what you did - I've barely ever used photoshop before. Is there a way you could send me the brush as a package to download? Thank you in advance Cyril Jul 27, 2020 at 17:34

    All you need is the brush image since I've already given you the settings to apply.
