Aperture photos on a Nikon D3000?

I just need to know how to work aperture on my camera, and how to do big and small aperture. I have a Aperture setting but I still don't know how to work it and what type of subject would be good to capture it.

Also is depth of field the same thing, or is there a difference? It involves small and large depth of field, so just wondering if it is the same thing or not.

Read the instructions that came with your camera. If you don't have the instructions, download them from the Nikon website.

This camera was the first to come with an interactive guide mode, which explains all of this to you. Now it would be a pity if you let all the efforts of those hard working Nikon engineers go to waste.

However here's a clue.

Narrow depth of field = big aperture

Big aperture = small f/number.

Aperture is ONE of the factors that controls depth of field (the others are the focal length of the lens and the camera to subject distance).

A small aperture (large f number, like f16 or f22) gives you a deep depth of field (everything in focus). A wide aperture (small f number, like f2.8 or f1.8) gives you a shallow depth of field (foreground & background blurred but subject in focus).

To change the aperture on your camera, you need to be in manual mode (M) or aperture priority (A).To adjust it, press & hold down the +/- button on the top right and turn the thumb-wheel on the back (this alters shutter speed when you don't have the +/- button held).

Don't forget that certain lenses will not go down to f2.8 - the maximum aperture it can manage will be marked on the lens. For example, the 18-55mm kit lens has a maximum aperture of f3.5-5.6. This means that the biggest aperture it can do is f3.5 (at 18mm focal length) and f5.6 (at the 55mm focal length).
