Scene camera is grey

[Triple_A_Batteries]

When i startup unity it’s all well but when i turn over to my scene view there is a 2d view which is grey.
Is it meant to be like this? On some tutorials when they start up they have a blue sky and their scene view is in 3d by default. Also when i created the project i made sure to click 3d.

Go to your camera inspector and you’ll see these options

Change Clear Flags and Background like you want.
