A photo walk slows attention in a useful way. It gives the eyes something specific to notice and gives the mind a gentle reason to leave urgency behind.
You do not need perfect images. The value comes from noticing shape, light, shadow, and rhythm.
When you look for color, texture, or repetition, the nervous system often shifts away from internal overload.
Reviewing a few favourite images later can extend the calming effect and help you notice what drew you in.
