Motion blur
This is when your subject isn’t completely still and you see their movements in the image.

Depth of field

This is when some part of the image is sharp and the rest blurry.

How to fix it?

- Shoot a larger f-number
F-number is how we describe Aperture.
With a larger f-number (f6.0) more things will be sharper in the image than at f1.2

Missed focus.

This happens a lot when your using a faster lens.
A fast lens is one that it’s Aperture opens at f1.2.

How to fix it?
- Use a single focus point every time you shoot.
- For portrait, place the focus on the eye.
- Use a larger f-number e.g F10
