Portrait Photography Basics That Actually Matter

Portraits feel intimidating because there are a hundred things you could adjust. In practice, a handful of choices do most of the work. Get these right and your portraits immediately look more intentional. A dependable starting point for a single portrait is f/2 · 1/250 · ISO 200.

A longer lens flatters faces

Wide lenses up close distort features, making noses look large and faces wider than they are. A longer focal length around 85mm compresses the face into natural proportions and lets you stand back five or six feet, a comfortable distance that also relaxes the subject. This is one of the clearest reasons to own a short telephoto prime. A 50mm is a cheaper alternative that works well, especially on APS-C where it frames a little longer. On full frame, anywhere from 85mm to 135mm is the classic portrait range; longer than that and you are shouting across the room. The best lenses for portraits guide covers the picks across systems.

Open the aperture for separation

A wide aperture like f/1.8 to f/2.8 throws the background out of focus so your subject stands out. Just remember that the sharp zone gets thin, sometimes only an inch or two at f/1.8, which makes focus accuracy matter more. For a single relaxed portrait, f/2 is a sweet spot: enough separation to soften a busy background, enough margin to keep both eyes acceptably sharp when the head is square to the camera. Step the subject several feet in front of a distant background so the blur has room to build.

Soft light is flattering light

Hard, direct light creates harsh shadows on a face. Soft light, from open shade, an overcast sky, or a north-facing window, wraps gently and is far more forgiving. The classic indoor recipe is window light: place the subject one to two feet from the window and turn them about 45 degrees toward it so the light rakes across the face rather than hitting it flat. Watch the shadow side: when the nose shadow and the cheek shadow nearly meet, leaving a small triangle of light on the far cheek, you have Rembrandt lighting, the flattering pattern painters used. Bounce a white card into the shadow side to keep it from going too dark.

Focus on the eyes

Sharp eyes read as a sharp portrait, even if the ears and shoulders fall into the blur. Use single-point or eye-detection autofocus and put the point on the near eye. At a wide aperture this is the difference between a keeper and a miss. Keep the shutter speed at least as fast as your focal length, so 1/125 or quicker on an 85mm lens, to avoid softness from your own hand movement or a fidgeting subject. Look for a catchlight, the small reflection of the light source in the eye, since it brings the eyes alive; a window or a softbox gives a soft, natural one. If you shoot a series, half-press to lock on the eye between frames rather than trusting one acquisition.

Pose for connection, not stiffness

The technical settings get you a clean frame; posing gets you a portrait that feels like the person. A few cues do most of the work: have the subject push the chin slightly forward and down to define the jawline and avoid a double chin, angle the shoulders rather than squaring them to the camera, and shift weight onto the back foot for a relaxed line. Keep talking so expressions stay alive; a held smile dies fast, while a prompt or a small joke produces a genuine one. Show the subject a good frame early to build their confidence.

What is the best lens for portraits?

An 85mm prime is the classic portrait lens for its flattering compression and background blur. A 50mm also works well and is cheaper, especially on APS-C where it acts a bit longer.

Why are my portraits not sharp at f/1.8?

The depth of field is very shallow wide open, so a tiny focus miss lands on the eyelashes or ears instead of the eye. Use eye-detection autofocus or stop down to f/2.8 for a little more margin.
