Exposure is a combination of 3 factors which determine the amount of light which enters your camera.
These factors are: shutter speed, aperture, ISO.
On my photography lesson we have practiced to do some photos in fast and slow shutter speed.
My examples of shutter speed:
S 1/125sec , F4.5 , ISO 100 2. S 2sec, F22, ISO 100
I have tried to take photos of people and transport in motion. I used my camera Nikon D7100 and tripod . I have learned that fast shutter speeds freeze movement and slow shutter speed shows movement as a “blur” whilst the background remains sharp.
My comparison between a “shallow depth of field” and a “deep depth of field” :
- A 1/25sec, F4.8, ISO100 2. A1/25sec, F4.8, ISO100
Aperture ( also known as f/stop) is how large the iris (or eye) of your lens opens up. Depth of field is how much of the area, measuring away from my camera, is in focus.
