I saw a render (attached) with really realistic looking shadows. Any clue how to do this bokeh-style shadow?
Thanks in advance

One way is to use geometry:
In the scene below, the shadow geometry is simply hidden to the camera in render time and has a grey transparent shader (the color controls the opacity).
Or you can use a texture for a similar effect like so:
Here is simply an image texture with transparent shader. The light in the scene is a sun lamp.
I found a great tutorial by Shane Spence Design for Blender and Keyshot that used image sequences of real trees to create this effect: https://www.youtube.com/watch?v=lYR0wlRmuZI
By using image sequences, you can even animate the shadows created. i assume that the bokeh circles can be achieved by using a larger spotlight.
It's kind of silly to come back here and answer my own question two years later, but I feel like other people would find this helpful. Take care!
