The correct answers are:
1. True
2. False
3. True
4. True
Explanation:
The f-stop value determinates the opening of the diaphragm, which is responsible for the light opening. If we use a small f-value, we will be able to isolate the object and let the background out of focus.
Shutter speed affects how long the light enters and aperture how much. The speed will determinate the time exposure, that’s why its number is symbolized by minutes and seconds. While the aperture the light intensity.
That’s true, this is one of the most used configurations in photographs. Other settings are 1/500, 1/250, 1/125, 1/30, 1/15, 1/8, etc. A slower setting is hard to manage and is usually used in low light or dark environments. You’d need a tripod to use them, as the camera has to be totally standing still.
The f/number determinates the opening. So, in a 1/60 setting, the diaphragm will be open for one second and receiving small exposure of light.
The other elements that can affect the photography are the lens and the use of the flash. The lens will allow you to control the image’s depth. And the flash is used when you need artificial light to improve your photo. They aren’t need in a sunny day, but very important if you’re indoors.
A photometer, or exposure meter, is another device that will calculate the light intensity. It’ll will provide you the f/number. Recently cameras have a photometer inside them, but if you want to explore any light possibility, an external photometer can measure the light intensity on the object. Comparing to the value shown by your camera, you can experiment with different options.
