Shutter Speed
I think motion blur is an important element in some photos because it shows how fast something moves while the environment around it doesn't move. I think the first two photos when Soleil is moving shows the intentional blur because she's moving on purpose while the third photo with the blurry hand is a mistake because we only intended on capturing the dice being blurry. If the camera says it's too bright it might be because its exposed in a bright environment for too long so you could just adjust the brightness or change the brightness setting entirely.

Both of these photos were taken on my phone but the first is focussed on the foreground and the second is focussed on the background.
