How can I get rid of the iPhone camera?

Question

The issue I am having is that when I press Cancel, the camera fades away, but then it comes right back. Now what I want at all.
Background
I have set up a UIViewController with nib and launch this view from a tab bar.  When the tab bar button is pressed the camera comes up as expected.  However, I cannot get back to my root controller because I cannot dismiss the camera.  When it is fading away, I can see the tab bar momentarily, but then the app goes right back to the camera view.
To be clear, I make use of  the following method calls:
[self presentModalViewController:picker animated:YES];
[self dismissModalViewControllerAnimated:YES];
Any suggestions or comments will be greatly appreciated.
Thanks!

Here you go!
==
- (void) viewDidAppear:(BOOL)animated {
  // Create a new image picker instance:
  UIImagePickerController *picker = [[UIImagePickerController alloc] init];
  // Set the image picker source:
    [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
  // set delegate to self
    [picker setDelegate : self];
    picker.showsCameraControls = YES;
          picker.navigationBarHidden = NO;  // NO = no help!
          picker.wantsFullScreenLayout = NO;
  // Show the picker:
          [self presentModalViewController:picker animated:YES];
    [self dismissModalViewControllerAnimated:YES];
    // release it
    [picker release];
    [super viewDidAppear:YES];
