Hey guys

I am a new Maya user and are only starting to learn the program now.

My friend gave me a car modelling tutorial which is great.
Now the problem that I find in the program is when I select a camera view , let's say I choose the side view. When I zoom in on the image plane then I can only zoom in to a point , thereafter the image plane blueprint of my car starts scaling, How can I set it up so when I zoom in that the image plain picture stays the same.

Regards
