Zone focus and hyperfocal distance are two timeless techniques that can help you improve your street photography once you’ve learnt how to use them.
Don’t be put off by the fancy sounding names, either. All it takes is a comprehensive yet easy-to-follow tutorial, which is what we have here, and some practice, which is what you’ll need to do after reading it.
Also included is a section on pre-focus, which is another closely related way of going beyond auto-focus and taking your street photography to the next level. Come read. You know you want to.
