Default Aperture not making a difference?

I have been playing around with my new fz-35 and its IQ is significantly better than the walmart point and shoots I used to buy before vacations.

however I have yet to take a photo in aperture priority mode that has any discernible difference between 3.6 and 8.0. It was my understanding that 8.0 would produce a shallower depth of field. Is it possible the aperture is somehow malfunctioning (though the camera still displays varying apertures for the photos taken) or am I doing something wrong. just how shallow is that shallow depth of field?

F/8 is a smaller aperture than f/3.6. The number is a fraction based on the focal length of the lens (F). F/8 will give you the most DOF, making everything look pretty sharp from close in to far away. F/3.6 will give you a shallower DOF, but not as shallow as the same aperture would on a larger sensor camera. (for the equivalent focal length)
What kind of shots are you trying to get the shallow DOF with?

Well I ducked outside and took some photos to test the difference in DOF, and it did mak a moderately significant difference. guess I was just taking pictures without enough bistance between walls etc for the effect to be noticable. however one thing I noticed taking pictures indoors is that a low aperture (assuming 3.7 is lower than 8.0 in photography) creates reddening. Here are some examples, both using flash. The first is an aperture of 3.7, the second, 8.0

Since you are using flash, your camera is balancing the color based on the color temperature of the flash, which is near daylight. The room lights have a lower temperature and are redder (that red/orange color you often see in indoor pictures). The wider aperture (3.6) is allowing more of the room light to show, resulting in the warmer colors.
