How do I take a panorama without the join going wrong?
Panoramas fail for three reasons — pivoting about the wrong point, moving at the wrong speed, and letting the exposure change mid-sweep. All three are avoidable.

Short answer
Turn on the spot rather than walking sideways, pivot around the phone rather than around your shoulders, and sweep slowly and evenly. Lock the exposure and focus before you start so the brightness does not step halfway across. Keep close objects out of the frame — they are what produces the visible break in a join.
A panorama is many frames stitched by matching overlapping detail. Every failure is the software being given frames it cannot reconcile, and each of those has a physical cause you can control.
Step by step
- Lock exposure and focus first.Point at the mid-brightness part of the scene, press and hold to lock, then start. Without this the sky at one end and the shade at the other are metered separately and the finished image has a visible brightness step.
- Pivot around the phone, not around yourself.Hold the phone close to your body and rotate on the spot, keeping the phone roughly over the same point in space. Swinging it out at arm's length moves the camera through an arc, which changes the relationship between near and far objects and breaks the stitch.
- Move slowly and at a constant speed.Most phones show a guide line and a speed warning. Slow and even beats fast and corrected. Stopping and restarting mid-sweep is worse than going slightly too fast.
- Keep the horizon on the guide.Drifting up or down forces the software to crop the finished image to the narrowest common band, which is why panoramas often come out much thinner than expected.
- Avoid close foreground objects.A wall, a railing or a person within a couple of metres shifts position between frames far more than the distant scene does. That parallax is the single most common cause of a visibly broken join.
- Avoid moving subjects, or use them deliberately.A person walking through the sweep gets stitched twice or sliced in half. If you want someone in the shot, put them at the start or end of the sweep and have them stand still.
- Sweep the direction that suits the light.Going from the shaded end towards the sun tends to produce a worse result than the reverse, because the lock is set on the darker end. Set the lock in the middle of the brightness range instead.
- Consider a vertical panorama.Turning the phone landscape and sweeping upwards captures a tall building or a waterfall in a way no single frame will. The same rules apply.
Tips
- For a room interior, the ultrawide in a single frame usually beats a panorama — panoramas of small rooms are all foreground parallax.
- If the join fails at the same place every time, something close to you is in shot at that point.
- Take two sweeps. They cost nothing and the second is almost always steadier than the first.
Common mistakes
- Walking sideways instead of turning — Translating the camera changes the viewpoint continuously, so near and far objects move relative to each other and cannot be reconciled. Rotate on the spot.
- Letting the phone meter as it goes — The finished panorama shows a clear brightness or colour step where the metering changed. Lock exposure before starting.
Questions people ask
Why did my panorama come out bent or curved?
Wide sweeps are projected onto a curved surface and flattened, which bends straight lines — most obviously a horizon or a rooftop. Keeping the sweep shorter, and keeping the horizon centred, reduces it.
Can I stitch photos on a computer instead?
Yes, and for a careful landscape it gives a better result: take overlapping frames with about a third overlap, all at the same manual exposure and focus, and stitch them afterwards. That approach also lets you use the main camera rather than a sweep mode.
