Capturing HDR on your phone

HDR stands for High Dynamic Range. It is used when a scene contains very bright and very dark areas that are difficult to record together. Modern phones often handle HDR automatically.

Before you start

Have the camera or phone beside you while you read. Do not try to memorise the page. Find each control or try each idea as it is explained. If a term is unfamiliar, the explanation here matters more than remembering the name.

What HDR is trying to solve

A bright sky and a shaded foreground can exceed what a single straightforward exposure records cleanly. HDR processing combines or maps tonal information to retain more detail.

Automatic HDR

Many current phones decide when to use HDR without showing a separate switch. That is normal.

Hold reasonably still

Phones can align frames, but subject movement can still create odd artefacts. Give the phone the best chance by holding it steadily.

HDR is not a 'make everything dramatic' button

Good HDR can look completely natural. Excessive local contrast and saturation are stylistic processing, not a requirement.

Moving subjects complicate things

Leaves, waves, people and vehicles may move between component frames. Modern processing often handles this well, but not always.

Common mistakes

• Looking for an HDR switch that your phone no longer provides.
• Using HDR to rescue every badly lit scene.
• Expecting moving subjects to align perfectly.
• Judging HDR only by whether the picture looks more dramatic.

What you should be able to do before moving on

You should understand the problem HDR solves even if your particular phone performs the process automatically.

If that still feels uncertain, repeat the practical. There is no benefit in rushing to the next lesson with a gap in the basics.
