Lagoon Lens

Travel west to east as the day goes on. Each wetland has its own quota, and the light drops at every stop, so exposure gets harder.

Aim

Move the mouse. The frame shows exactly what the photo will contain.

Focus

Hold the left button. Autofocus locks on the bird nearest the centre. The box turns amber while it hunts and green when it locks. Low light and fast birds slow it down.

Shoot

Release the button. Releasing before focus locks gives a soft frame.

Zoom

Scroll from 200 mm to 600 mm, or press [ ]. A tighter frame scores more for framing but is harder to keep on a moving bird.

Aim

Push the joystick on the left. The further you push, the faster the frame moves. A full push is quick but can spook nearby birds. You can also drag anywhere on the screen.

Focus

Press and hold the round shutter button on the right. Its ring turns amber while autofocus hunts and green when it locks. Low light and fast birds slow it down.

Shoot

Lift your thumb off the shutter. Lifting before focus locks gives a soft frame.

Zoom

Tap T to zoom in and W to zoom out, or pinch with two fingers. Hold a button to keep zooming. A tighter frame scores more but is harder to keep on a moving bird.

Pause

Tap II at the top right.

Scoring

Each frame is graded out of 100: sharpness 35, framing 30, exposure 15, composition 10, plus bonuses for behaviour such as a kingfisher's hover or dive. Two stars or better counts as photographed.

Quota

Each round sends up ten birds. Photograph enough of them to meet the quota. Every frame uses space on your memory card.

Stay quiet

Fast, jerky pans spook birds near the frame. Firing at an empty frame startles the whole flight and cuts its time.

Enthusiast

1 2 3 setTap the shutter-speed button at the top left to cycle 1/500, 1/1000 or 1/2000. A faster shutter freezes motion but darkens the frame in poor light. The small viewfinder at bottom right previews exposure.

Pro

Q E change ISO and B togglesThe ISO and burst buttons at the top left change ISO and toggle a three-frame burst. Higher ISO brightens the frame but adds grain. Burst fills the camera's buffer.
