Operator error. Like I said, it's not for handheld use (the only way to get blurry shots).

Correct way:

- Settings: Set the number of shots to 32 or higher. 1s interval. 3s pre-start timer

- Point at scene. Lean it against an object (don't touch/move) or mount on a tripod.

- Select exposure/focus/whitebalance with longpress (I select a light part of the scene, exposure/gain can be adjusted upward afterwards).

- Lock exposure/focus/whitebalance (could be an L in the middle, or text on your screen left, boldface is locked in)

- Shoot.

- After it's done (don't touch!) adjust the exposure if needed.

If you want even higher quality images, you can subtract banding noise (also mentioned in the PDF by the way).

In order to get the banding noise image for your camera:

- set shots to 128, delay 5 seconds

- point lens at light source (e.g. on table, don't move)

- hit shoot, put piece of white paper over the lens

- wait ~2mins (till it stops shooting).

- Select N in middle, "save image as noise fingerprint".

Then take another shot of a scene. Once final pic shows, hit N, now say "remove banding noise".
