It depends on what your shooting, you can also use AUTO mode on your camera to have your camera choose what aperture it thinks its best. If you have a high shutter speed than you might want to choose a bigger aperture (f/2 around there). But if you want a larger depth of field you need to choose a lower aperture (around f/32) and a lower shutter speed.
Aperture Priority has the camera set the shutter speed for you allowing you to set the aperture and it will set what shutter speed it thinks is best for your current light situation.
To set the aperture on a Nikon D3300 camera, turn the mode dial to Aperture Priority mode (A or Av). Then, use the command dial to adjust the aperture value to your desired setting.
It is a set that you derive from some initial data or formula depnds on the question. I assume you know what a set is?
Aperture priority lets you set the aperture you want and the camera sets the shutter speed for you. You use it when you want to control depth of field. Shutter priority lets you set the shutter speed you want and the camera sets the aperture for you. You use it when you want to control how motion is rendered in the photograph. Program mode sets both shutter speed and aperture for you. Use it when you are not concerned with aperture or shutter speed control.
Need to KNOW the YEAR of the engine. And what it is in.

I don't know the D300, but similar Nikon DSLRs have a secondary control dial on the front, not far below the shutter button.
Shutter priority mode allows you to set the desired shutter speed while the camera adjusts the aperture, whereas aperture priority mode lets you choose the aperture setting while the camera adjusts the shutter speed.
To set the aperture on a Nikon camera, you can adjust it using the command dial on the camera body. Turn the dial to change the aperture value to a higher or lower number, which controls the amount of light entering the camera lens. A lower aperture number (e.g. f/2.8) lets in more light and creates a shallower depth of field, while a higher aperture number (e.g. f/16) lets in less light and creates a deeper depth of field.
You should use aperture priority mode on your camera when you want to control the depth of field in your photos by adjusting the aperture setting while letting the camera automatically set the shutter speed for proper exposure.
