The fast and frantic nature of street photography often requires you to think fast on your feet, or rather fingers. Whether it’s a moment that you want to flood the sensor with light to achieve a pin-sharp shot, or you want to slow the shutter down a little to inject a bit of arty motion - diving into the settings in the conventional way, changing from aperture priority to shutter priority, can be a long enough delay that leads to you missing the moment.
One of my favorite solutions to this problem is to set up custom modes. Most cameras from enthusiast-level upwards have some sort of custom mode functionality, usually labelled as C1, C2, C3 etc. It’s even better if these are physically printed on the mode dial as it means you can dive into them with a quick turn of the dial.
