Aperture on a Fuji 21800 bridge camera?

[CourtneyB]

I'm still new to my camera and I cant seem to get the aperture right..
I have aperture priority and I can change the shutter speed and exposure, but I only seem to get 2 options for the aperture. E.g it would give me a choice of f3.1 and then a choice of f11.
How can I sort it so I can increase the depth of field more and vice versa?

e.g, I would want it be be f5, which only comes up if I mess around with the zoom and exposure etc

I can't seem do it on other settings either

Thanks

I'm pretty sure that on your camera the "aperture" setting is simply a ND filter put ni fron of the lens to control the amount of light let through; it has no bearing on aperture size at all and so has no effect on DoF. Besides, creating shallow DoF on such a small sensor is damn dear impossible anyway so having a proper variable aperture wouldn't make much difference anyway.
