iPhone lenses 0.5x, 1x and 2x: which one for photos of people

Which iPhone lens is best for photos of people?

The 1x lens is the safe default. It is the main camera, it handles low light best and it gives natural proportions at a normal distance. Use 2x when you want a closer, more flattering portrait and can step back. Use 0.5x only when you need the extra width. Not every iPhone has every option, and the Camera app only shows the buttons your phone supports.

What does 0.5x do?

The 0.5x lens is an ultra wide camera. It fits much more of the scene in the frame, which is useful for groups in tight rooms, tall landmarks and low-angle full-length shots. It also exaggerates things near the lens and stretches shapes near the edges, an effect described in the Wikipedia articles on wide-angle lenses and perspective distortion. Keep faces toward the center and do not hold the phone close to a face.

What does 2x do?

The 2x option gives a tighter view that suits portraits, because a longer focal length flattens perspective, as the Wikipedia entry on telephoto lenses notes. Depending on the model it uses a dedicated camera or a crop of the main sensor, and the Camera app handles that for you. Step back two or three paces, so you fill the frame without the phone being close. Hold the phone steadily, since a longer view magnifies shake.

How does Posepass suggest a lens?

Every pose lists a lens: 0.5x, 1x or 2x. Crosswalk stride uses 0.5x, low, to show the street. Coffee to go uses 2x at chest height to the knees. Cup in both hands uses 1x. A lens chip on the camera shows the suggestion as information only. You tap the lens in the Camera yourself, since Posepass does not switch it. The direction text says switch to 0.5x, stay on 1x, or switch to 2x and step back.

How far should I stand with each lens?

Distance changes proportions, not only framing. With 1x, a full-length shot is about three to four paces from the person. With 2x, you step back further, around five or six paces, to get the same frame. With 0.5x, you can stand closer, but keep your distance from the face. Take the first frame, check head and feet, and adjust by a step. The Posepass direction take three steps back often goes with 0.5x group poses.

Why do my group photos look stretched at the edges?

You are using a wide lens and people stand near the edge. Pull them toward the center, step back and use 1x. Or keep 0.5x and put the tallest in the middle. Another fix is to stand them in a curved line, with the outer people a step closer to the phone. A group of five is fine on 1x if you step back four paces.

Does the lens matter for low light?

Yes. The main 1x camera usually has the best low-light performance, so use it indoors. The 0.5x and 2x views may be noisier in dim cafes. Move closer to a window or a lamp instead of switching lenses, and ask the person to stay still for a second after the shutter sound.

What about zooming in between the lenses?

You can pinch to zoom, but it is better to use the fixed lens buttons, which are sharper. If you must crop, leave extra space around the person when you shoot, so you can crop later. For people, try to stay at the lens buttons and move your feet.

A simple lens routine

Start at 1x. If the person does not fit, step back first, then go to 0.5x. If you want a tighter, softer look, go to 2x and step back. Always check the edges for stretched faces and the level for tilt. The camera guides in Posepass show the horizon and level on the live view.

What about the selfie camera?

The front camera is a single wide lens on most models and it is usually closer to the face than the back cameras. Hold the phone a bit higher than the eyes, keep your arm slightly bent and do not tilt the phone down much. Newer models let you widen the view for a group selfie. For anything more than a quick selfie, ask someone to use the back camera, which has more resolution and more lens choices. Posepass includes a button to flip the camera when you need the front lens.

Which lens suits which Posepass situation?

The library mixes all three, depending on the pose.

• City: mostly 1x, with 0.5x for walking shots and 2x for portraits like Coffee to go.
• Beach: 0.5x for low shots such as Shoreline walk, 1x for seated and leaning poses.
• Cafe: 1x for tables and 2x for close frames such as Read the menu.
• Couple and Group: 0.5x for walking and group frames, 1x for hugs and sits.
• Travel: 0.5x for most poses to fit the sight in the frame.
• Full outfit: mostly 1x from a low phone, 0.5x for walking and jumps.

Should I always use the same lens for a set?

Not necessarily, but it keeps the look consistent. Pick 1x for a seated set at a cafe, or 0.5x for a day of travel poses. Switching between lenses changes the feel of the background and the shape of faces. For a shot list of six poses, it is fine to change as the pose asks, but keep the distance and angle in mind, and check the first frame after each change.

What are the common lens mistakes with people?

Four slip-ups come up often.

• Holding the 0.5x lens close to a face, which makes noses large and ears small.
• Using 2x indoors in dim light, which adds noise or shake.
• Zooming by pinching instead of using the lens buttons.
• Switching lenses between frames of the same pose, so the series looks inconsistent.
