I tend to do a lot of street photography as i'm always traveling, its quick and easy but making it look good, not always, so there is a simple technique I use to get good Bokeh in a shot.
Firstly, so we're all on the same page Bokeh for those who aren't familiar
In photography, bokeh (/ˈboʊkə/ BOH-kə or /ˈboʊkeɪ/ BOH-kay; Japanese: [boke]) is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light".
The background can make a huge difference in how your street photography final image will appear.
Walking around it kind of 'is what it is', the old adage of F8 and be there works well, but doesn't always give you great bokeh. I'm not a shooter that is comfortable approaching people to ask to take a shot, I prefer to speak to them afterwards, if I can, because of being in so many foreign lands. Most of my walk around shots I take 'from the hip'
An example, good, but not great because its shot at F8, this would have been amazing with good bokeh, but I doubt I could have got the same expression
