What is f-stop, aperature, and ISO?

Well i just got a nikon D3000 because i'm a beginner. Is this a good camera? Please write in simple words i'm just a kid

Those are three things you learn about by reading a basic photography book or taking a class.

It's gorgeous. I'll never stop being a kid, so you have time enough. Just dive in the manual and put something from yourself

The D3000 is a great camera that will shoot well in automatic and allow you more advanced manual control as you learn. Here is my attempt at a simplified answer:

Aperture is a term that describes how wide a camera lens opens.

f-stop is a term that defines the aperture setting on a camera. Easier to visualize on old manual cameras where itis visually marked on the lense but still app. If you think of light as speed on a car, the aperture is kind of like the amount of gas you give a car and the speedometer would be like the f-stop.

ISO is a term that refers to how sensitive film (on a digital camera like the d3000 the sensor replaces the role of film) is to light. The higher the number, the more sensitive it is to light. High ISO's have a tradreoff. The higher the number, the lower the quality of an image. Generally you want to shoot at the lowest ISO you can get away with considering the available light.

Hope this helps

ALL that is explained in your user manual - you will find if you become "one" with it, your experience with your fine D3000 will be excellent

An f/stop is a calibrated number to let the photographer know what aperture is being used in the lens.

ISO is what describes the sensitivity of the sensor to light

It is up to the photographer to balance the shutter speed, aperture and ISO to provide near perfect exposure under lighting conditions from bright sun to shooting sports indoors

Just remember to have fun and experiment!

F-stop and aperture are one of the same thing. They refer to the size of the hole in the lens that allows light to go in.

ISO is how sensitive the sensor is to the light. Lower ISOs are less sensitive and higher ISO settings like 1600 or 3200 more sensitive, but create more "noise" (basically little spots of grain in your photos).

Aperture and ISO are only two of the three things that make up the "exposure triangle" though. The last part is shutter speed, which is somewhat self explanatory. Leave the shutter open for, say 8 seconds, and that lets in a lot of light as opposed to something like 1/2000 of a second.

Well kid - the people that wrote the manual were chosen for their ability to explain things to buyers with poor xomprehension skills. We have had no such training. Read the manual.

To understand more how aperture/f-stop affects the image, set your shutter speed to 1/60 and iso to 100… Take a shot while adjusting the aperture from smallest number to the biggest.smallest f-stop number means bigger a aperture which allows more light to the sensor and vice versa. Then compare the images.
do the same with iso.set the aperture to f9, shutter to 1/60 and adjust the iso on each shot.sometimes experimenting things by yourself will make you learn faster.last to experiment is the shutter speed.bottomline, the right combination of aperture and shutterspeed will give a correctly exposed images.
