My photos are blurry

Sharpness problems, from shake to focus

Why it happens

The shutter speed was too slow for a moving subject — even 1/60s blurs walking people.
Camera shake: at slow shutter speeds your own hands blur the whole frame.
The camera focused on the background because the focus point sat in the middle of the frame.
The sharp zone was thinner than you thought — at f/1.8 it can be a couple of centimetres.

1
Raise the shutter speed: 1/250s for people, 1/500s or faster for anything moving quickly.
2
Let ISO rise to pay for the faster shutter — a grainy sharp photo beats a clean blurred one.
3
Move the focus point onto your subject (or use eye-detect AF) instead of focusing in the centre and recomposing.
4
Brace yourself: elbows in, lean on a wall, or use a tripod for anything under 1/60s.
5
Check whether the whole frame is blurry (shake) or only the subject (focus) — they have different fixes.
