Project disappears

When I zoom out in camera mode, the image disappears for some reason. Please help me!

I added pictures of what happens as I zoom out.




First time adding a picture, IDK how to; hope this works

Select the camera, Increasing this number will push the fog back more.

do the same thing in properties panel(n key in 3d view) to change the viewport draw distance (labelled as “clip”) this will effect the user perspective view instead of the camera, as well as any other non orthographic views make it easier to work on bigger scenes
