Aperture setting question

[Jana_NJ]

I just bought a new camera
not a DsLR but a digital that has this capabilities but without changing lens
But I have all manual capabilities
I still have to read a lot in my new huge manual, but
I saw some videos on youtube showing about APerture to make a bluer background, and when I set my camera just trying out of the box in the anxiety of trying , I set the aperture to 2.8 but it didn;t seem to work that much, altough i have to upload to see , but my question is
Is that work at night with flash? I also have to reduce something else like
ISO?
thanks guys just a beginner here...

The smaller your aperture (f/stop) number the "wider" the opening and the more light you are letting into your camera. This creates a blurrier background also known as "bokeh". You will get less area in focus with a wider aperture.

You don't need to use a flash to get the blurrier look. You would need to up your ISO if you are in low light in order to get enough light for the right exposure. The higher your ISO the more noise you will get (dependent upon your camera). Noise is extra pixels that give photos a grainy look.

Hope this helps. There are some other threads in the photog forum that might be helpful too.

It's much harder to get that nice blurred background with a point and shoot camera; they just don't do it like an SLR can. It may work better if you zoom out as far as you can and put as much space between your subject and the background as possible.

I did get a good shallow depth of field with my point and shoot (though technically a ZLR, or a Prosumer P&S). It had aperture priority, but it would only open to about f4.5. I got this picture (SOOC) by backing up as far as I could and using my zoom as far as it would go. That's an easier way to "fool" the camera into getting a shallow DOF. (I see Laura and I were typing the same thing at the same time!)
