Don’t forget, as you change the f stop, you must compensate the exposure by also changing the shutter speed. In some cases, it will be too bright to use a open apeture like f 2.8, or too dark to use f 16.
Remember that you must adjust the f stop to match the shutter speed you have selected to get a correct exposure. You may find that you can not use a low or slow shutter speed in the bright sun, as there is too much light present. In that case, you must go someplace where there is less light or wait till dusk. The same is true of high shutter speeds, which often require you to open the lens to get enough light to make a correct exposure, this may not be possible indoors, for example.
