Answer:
What is Exposure?-the state of being exposed to contact with something.
What can affect illuminance?-Two factors affect illuminance, the amount of light actually hitting your subject; and the surface quality of your subject and how it reflects light. ... Closing or restricting valve, using a smaller aperture, also called stopping down, allows less light into the lens.
How do camera settings influence exposure?-Exposure depends upon subject luminance (illumination and reflection)and camera settings (f/stops, shutter speed and ISO). The Aperture<- your second lab link 1. ... Closing or restricting valve, using a smaller aperture, also called stopping down, allows less light into the lens
Describe how the aperture size relates to the size of the lens opening.--Aperture is how we describe the size of the opening that determines how much light can come into your lens (like an iris on your eye). Assuming two lenses have the same size opening, a wider aperture value (smaller f stop #) will let more light in than the same size lens with a larger minimum aperture value.
How does the amount of light allowed through the lens influence a photograph?-The aperture of a lens is the opening in the diaphragm that controls how much light is allowed to reach your focal plane (film or sensor). ... The wider an aperture is, the more light it allows through, and the smaller the number under f/ is. A common wide aperture is f/2.8, and is called a "fast" lens
Describe a situation that you might want to adjust the f-stop for your photograph? What benefit would you gain? Shutter Speed
What is the shutter?
How do the shutter speed numbers relate to the time the shutter is open?
If you were to set the shutter speed for a long opening, what effects might you notice in your photographs? Why?
The f-stop (or aperture) controls how much light you let in. It's easier to understand it if you look at your camera lens and play with the f-stop- you'll see that the shutter becomes more closed or more opened in your lens. So, a higher f-stop means that the shutter is closed more, and a lower f-stop means that the shutter is closed less; therefore, less light is let in with a higher f-stop, and more light is let in with a lower f-stop.
So, if I'm shooting in bright daylight, I'll want to raise my f-stop, because if I don't, my photo may be overexposed (where the whites are completely washed out- this is pretty much a #1 don't do of photography).
(Plus, you can't recover overexposed images, so if your image is overexposed, you're pretty much screwed.)
But if I'm shooting at let's say, night/indoors/an alley, I will want to lower my f-stop to let in more light. If I don't do that, my image may be underexposed (where the blacks are extremely dark. You can recover underexposed images to some extent, but your photo may become extremely grainy if it's too underexposed. Also, not underexposing your image saves lots of time in Lightroom/Photoshop.
The shutter is the thing inside your camera lens that controls how much light is let in. It can widen/narrow itself (aperture) and snap shut (shutter speed). Without a shutter, all your photos would just be complete white.
The shutter speed numbers correlate to seconds. 1/16 shutter speed is 1/16 of a second, 1/128 shutter speed is 1/128 of a second, 5 shutter speed is 5 seconds, etc. This is how fast the shutter closes in between when you press the button and when the shutter closes. Longer shutter speeds mean more light is let in, and faster shutter speeds mean less light it let in. Another thing controlled by shutter speeds is blur on images. If I take a picture with a short shutter speed on a waterfall, the shutter opens and closes very quickly after I press the button, which means I can get photos of the waterfall's individual droplets where it basically looks frozen in time. However, if I take a picture with a long shutter speed of that waterfall, the water will look extremely smooth because of the delay in between when I pressed the button and when the shutter closed.
So, if you set the shutter speed for a long opening, you'd let in more light and let things blur more. If you take a picture of a waterfall, you'll notice that the water is extremely smooth. If you take a picture of a city street, you'll notice that the people walking by will be blurred as if they're all in motion. If you take a picture of the night sky (you have to have a really long shutter speed for this and a low f-stop) you will be able to notice all of the stars in the night sky, and how the stars move around. (If you haven't tried this before I'd suggest doing it, it's really fun.)
