Lenses

1. I would use a telephoto lens to take a pictures at a concert if you are far away.
2. I would use a prime lens for a more indoor situation or in low light.
3. I would use a wide-angle lens for like group photos or to get a whole scene in a picture.

1. Depth of field- The distance between the nearest and farthest objects.
-You can't tell how far the picture is

2. Light- The lighting around the environment.
-Need good lighting for photos 

3. Shadows- Dark image casted by something in the way of light.
-I really don't know

4. Exposure- How long you expose the lens to light.
- Good for dark situations or bright.

5. Aperture- Controls how much light the lens takes in.
-So you don't take to bright or dark pictures.

6. Shutter Speed- Tells how long the shutter speed is open when the picture is taken.
- To capture more things 

7. ISO- Relative amount of light necessary to give a proper exposure.
- To get the right amount of light
