The quick answer
Choose a visible reflection, change the phone’s height to see how much of it enters the frame and wait for a moment that suits the water’s movement. Decide whether you want both the subject and its reflection or only a reflected fragment. Keep enough of a reference frame to understand the scene before experimenting with a tighter composition.
Choose the reflected subject before the framing
A reflective surface is not yet a complete subject. Name the element you want to show: a building, a tree, a colorful sign or an abstract patch of light. This helps you choose what to include when the water reflects more than you expected.
For a building in a shallow puddle, first make a reference that includes the building, puddle and surrounding pavement. Then look for the reflected roofline. If that is the important shape, compose around it instead of keeping every part of the original scene.
Explore height without committing to one formula
Adobe’s reflection guide discusses changing camera position and shooting low around puddles. Compare a standing view with a lower one from a stable position. Watch what enters and leaves the water’s reflected area as the phone moves.
Keep the phone above the water and remain on firm ground. You do not need to balance at the edge of a pond to make the comparison. If a low view is uncomfortable or inaccessible, use the standing viewpoint as a constraint and find a smaller reflected detail within it.
Work with the surface you actually have
Adobe notes that wind and ripples affect reflected scenes. If you want a recognizable mirror image, observe the water before shooting and make a few frames as the surface changes. If it remains broken, choose whether the moving pattern is worth photographing on its own.
For the puddle example, compare a clear roofline with the same roofline interrupted by a passing ripple. Neither has to win automatically. The first may describe the place; the second may communicate rain or movement. Select according to the image you intended, not a universal rule about perfect symmetry.
Compare the complete scene with a reflected fragment
Adobe discusses both a subject with its reflection and a reflection-only view. Compare those options using the same scene.
The complete relationship. Include the physical subject and the reflected version. Nikon notes that a centered horizon can work for symmetrical reflections; compare it rather than applying a grid rule mechanically.
The reflected fragment. Crop out the real subject and let the water carry the image. Inspect the edges for a stray shoe, drain or bright piece of litter.
Preserve the reflection you came to photograph
Canon’s polarizer guidance explains that the filter can reduce water reflections. If you already use one, compare its rotation or an unfiltered view before assuming a stronger effect is better. Removing the glare may also remove the reflected subject.
Check the saved photograph for a recognizable focal feature, awkward edge crops and a distracting tilt. Keep the wider reference alongside an abstract crop so you can trace the result back to the scene. If you later rotate the image for a creative presentation, make that a deliberate viewing choice rather than an accidental orientation error.
Common questions
Should I always place the dividing line in the center?
No. Compare centered symmetry with a frame that gives more space to the important subject or its reflected version.
