1 . A photograph’s exposure d A photograph’s exposure determines how light or dark an image will appear
2 . Achieving the correct exposure is a lot like collecting rain in a bucket.
3 . While the rate of rainfall is uncontrollable, three factors remain under your control
4 . the bucket’s width, the duration you leave it in the rain, and the quantity of rain you want to collect.
5 . There are many different combinations of width, time, and quantity.
6 . Aperture: controls the area over which light can enter your camera
7 . Shutter speed: controls the duration of the exposure
8 . ISO speed: controls the sensitivity of your camera’s sensor to a given amount of light
- aperture affects depth of field
10 . shutter speed affects motion blur
- ISO speed affects image noise.
12 . A camera’s shutter determines when the camera sensor will be open or closed to incoming light from the camera lens
- The shutter speed specifically refers to how long this light is permitted to enter the camera
20 tip’s I learned for photography
- For lenses anything under 50 is wide and anything over it is telephoto and if it’s on 50 it’s fixed
- Shutter speed is a powerful tool for freezing or exaggerating the appearance of motion
- With waterfalls and other creative shots, motion blur is sometimes desirable
- If a properly focused photo comes out blurred, then you’ll usually need to either increase the shutter speed, keep your hands steadier or use a camera tripod.
- It is specified in terms of a f-stop value
- In photographer slang, when someone says they are “stopping down” or “opening up” their lens
- ISO speed is usually only increased from its minimum value if the desired aperture and shutter speed aren’t otherwise obtainable.
