Camera's "Image Area" is Tiny

i’ve been following along serveral tutorials, and am unsure where i messed up my camera settings. but this file alone has an “image area” about 1/12 of the screen’s full resolution. How do i change it back? what setting regulates the scale. I am attaching a screen shot because i have no idea what any of these settings might be called.


any help clarifying what the settings are called, or even what the broken pieces are called would be helpful (i dug around a few forums, but failed to find any help because I can’t figure out what any of these settings are called)

thanks in advance,
Nathan

Try this: Switch to camera view. Press N while your cursor is in the 3d view window. This opens properties shelf. Scroll down until you see lock camera to view, uncheck this, and then zoom in. When you have the camera boundaries the size you like check the box again (if you want to)

that allows me to zoom, but the grayed out area doesnt adjust with that setting. if i unclick “passepartout” under Properties/Camera/Display it stops being dark, and i can adjust the alpha value of that black letterbox, but the viewport itself doesn’t adjust with any of those settings

Assuming you have not changed from the default keyboard shortcuts, follow what DruBan says and it works.

To autofit the camera view in the viewport you can also use the Home key on your keyboard

pressed N
Checked Lock Camera To View
Zoomed in and Out,

unfortunately, it does not adjust the size of the viewport…
it does zoom the scene in and out, but does nothing to the viewport.

is there a possibility i have a bug like this?

i was messing around with camera settings, i’m just uncertain of when the width of the viewport changed.

We’re probably having a communication problem. When I say viewport I mean the entire 3Dview window. Within it is the camera frame. When i say ‘size’ of the camera frame I mean the width or length in the viewport. To change the ‘shape’ of that, i.e. the proportions you need to change settings in the camera properties. To change the size you view that fixed proportion rectangle at in the viewport, you do the procedure I suggested earlier.
HTH.
Sometimes the perspective camera seems to stall during zooming. Not sure if this is a bug. Try ctrl+middle mouse drag to see if that unfreezes the zoom.

Just press <Pos1> to maximize your camera to the current viewport, or use your mousewheel to zoom in/out.

Perhaps the fact that I don’t have a mouse is a hindrance. I’m on a MacBook Pro and using the trackpad. I can ZOOM using a pinch with two fingers, but it doesn’t do anything to the camera frame… Is it possible I’m not zooming the same?

And more than likely we are having a communication issue, I have just started using blender and am referring to things as best I can figure not necessarily any official documentation.
