"No camera found in Scene" error I just started blender and one of the main things you have to do is to render to make an animation, but I can't seem to do that. Whenever I click Render and then render image or render animation, at the top of the screen it says 'No camera found in Scene "Scene". I don't know why this is happening.
I don't know any other reason, except you have no camera in your scene. 

You can add a camera by: Shift + A  > Camera.

Or maybe you have a camera in you scene, but it is switched off for render. Check the little camera icon on right side in Outliner.

There are Eye for visible in viewport, arrow to prevent selection, and a Camera to toggle visibility in render.
