A familiar walk at one focal length
Keeping the angle of view steady makes small changes in distance and position easier to notice.
A familiar route is useful because the subject does not need to be discovered all at once. The doorway, tree, or row of windows is already known. With less pressure to find something remarkable, attention can move to how familiar things sit inside a rectangle.
Use one view
Choose one focal length or one camera on a phone and leave it there for a short walk. This is a limit for the exercise, not a claim that zooming is bad. When the frame does not fit, consider moving a little, changing height, or leaving the picture unmade.
Keep to places where walking and stopping are permitted. Never step into a road or onto private ground to preserve an exercise. A missed frame is a reasonable outcome; it can be more useful than an awkward or intrusive one.
Notice the distance
- Make one photograph that includes the subject's surroundings.
- Find a detail without switching lenses or using digital zoom.
- Look for two subjects that overlap differently when you move sideways.
Changing position changes perspective, not just the amount of subject in the frame. Watch which edges separate and which merge. On the next pass, stop before raising the camera and predict those relationships. The exercise becomes useful when the view begins to feel familiar enough to anticipate.
