Shooting through glass in street photography introduces two layers of challenge at once: you are managing reflections and glare while also composing a scene you cannot physically enter. Done well, the window itself becomes part of the image.
Managing Reflections and Glass Glare
The most reliable technique for eliminating unwanted reflections is pressing your lens hood or a dark lens cap directly against the glass. This blocks the ambient light that would otherwise bounce off the window surface and back into your sensor. The contact needs to be firm enough to seal out light but gentle enough to avoid vibrating the glass and blurring your subject. A polarizing filter is the optical solution: rotate it until the reflection fades, which works best when the angle between your lens axis and the glass surface is around 56 degrees. Note that a polarizer costs you one to two stops of light, so you will likely need to compensate with a wider aperture or a higher ISO.
Reflections can also be used intentionally. The window surface becomes a natural double-exposure tool: the reflected street scene overlaid on the interior subject creates layered images that are impossible to achieve in post-processing. For intentional reflection work, position yourself at roughly 45 degrees to the glass rather than perpendicular to it. The overlapping images work best when the exterior reflection and interior subject have similar tonal ranges, otherwise one will dominate and the other will disappear.
Exposure Settings for Window Shooting
The biggest exposure challenge when shooting through shop or cafe windows is the extreme contrast between a bright exterior and a dim interior. If you expose for the window light falling on a subject inside, the street outside will blow out. If you expose for the street, the interior subject goes dark. In most cases, exposing for the subject inside and accepting a bright or clipped background produces the stronger image: it isolates the subject and creates a painterly quality that mirrors how we actually experience looking into a lit room from outside.
Use spot metering pointed at your subject’s face or hands and set exposure compensation to plus 0.7 to plus 1.0 to lift the subject out of the shadows without destroying the window light effect. Shoot in RAW to preserve the most highlight recovery flexibility in post. A fast lens at f/2.8 or wider helps in dim interiors, but stopping down to f/5.6 sharpens the glass surface and any dust or smudges on it, so find the balance between subject sharpness and lens cleaning.
Composition Strategies Specific to Windows
The window frame is one of the most direct framing tools in street photography. A wide horizontal shop window with multiple panes creates a natural grid that can separate subjects into distinct panels, like panels in a comic. A single small window isolates one subject with implied confinement. The window ledge, frame, and sill all work as leading lines that pull the eye toward whatever sits behind the glass.
Consider your camera height relative to the window. Shooting from slightly below the center line means interior subjects appear to look out toward you, which creates a more direct geometry. Move laterally along the window to change which interior elements align with the vertical frame edges before committing to a shot. Condensation and rain streaks add texture: stop down to f/8 so droplets sharpen into distinct shapes rather than blurring into general haze.
Common Mistakes to Avoid
- Using autofocus without checking what the camera locked onto. AF systems frequently grab the window surface instead of the subject behind it, particularly with phase-detection systems on high-contrast glass edges. Use manual focus or confirm the focus point before shooting.
- Forgetting to clean the glass before shooting. Smears and fingerprints on shop windows create soft halos around bright light sources that are nearly impossible to remove in post.
- Standing so close to the window that your own reflection appears in the frame. Step back far enough that your body falls outside the reflection angle, or wear dark clothing to minimize your own presence in the glass.
- Ignoring the visual weight of the frame itself. A window that takes up 80 percent of the image with a tiny subject behind it is usually a weaker composition than a tighter crop that emphasizes the subject.
- Neglecting to check whether subjects can see you. People inside a brightly lit room looking out into a darker exterior often cannot see a photographer outside, but in some situations they can. Being aware of this protects your candidness and your courtesy.
Frequently Asked Questions
Is it legal to photograph people through windows in public? In most countries, photographing what is visible from a public street or sidewalk is legal, including through shop windows. Photographing into private residences through windows, even from a public area, falls into a different legal and ethical category and should be avoided. When in doubt, photograph only clearly public-facing commercial spaces.
What focal length works best for shooting through windows? A short telephoto in the 50mm to 85mm range is usually ideal. It lets you stand far enough back to avoid reflection issues while still filling the frame with your subject. Very wide lenses exaggerate reflections and require you to be so close to the glass that your own presence often appears in the image.
