Hi,
I have an olympus C750UZ, and need help understanding the shutter and aperture settings. I am trying to take pictures of objects, and I want the object to be clear, but the background to be blurred. I have modified the shutter and aperture settings to different values, but this doesnt seem to have much of an effect, and the manual doesnt offer any help.

Any explanations, suggestions or links would be appreciated.

Thanks,

Hi Anag
this may help you, I dont personally use your type of camera but some basic shooting methods can be applied to most cameras.
With yours I note that the maximum aperture is f2.8 (very usefull for low light shots) and of course shallow depth of field which is what you are trying to create
(i.e. object sharp background out of focus/blur)
so an easy way to achieve this :
set your camera on AV mode (aperture priority mode) then sellect a wide aperture say f2.8 or f4 . the camera will produce a correct exposure by adjusting the shutter speed to suit.
Make sure you focus accurately on the object, using focus lock if the subject is off centre or does not line up with cameras focusing points in viewfinder.
do some test shots and check as you go.
Now try out the next method, use the zoom function and towards the telephoto end again a wide aperture try framing the object from various distances( a tripod is really usefull for these tests) and make sure you get the focus right.
try the wide angle end of the lens ( I think 28mm on your olympus)
this time work in close to the subject, move away even a small distance with wide angle and everything will appear to be sharp. the great thing about digital is it does not cost to shoot these tests and you see the results straight away.
p.s. get to know what your camera is capable of by tests first.
if you already have pics and need to blur the background its pos with photoshop or other image editing software so all is not lost.

Some usefull links:

The DCview page (links to 6 tests)

Try to fully understand the two autofocus mode (Iesp and Spot).

Now a link to some practical use of a C765 (should the same for the C750):

After that, you're ready !

Hope it helps,
