Exposure deals with
The elements of light, quality and timing:
Arranging them and balancing them in a way that allows you to make the picture you want.
It's all about balance
Camera: ISO
Keep this number as low as you can
The higher the ISO number
The more sensitive to light the image is-The less light is needed- the more noise in the phot and lower the resolution
The lower the ISO number
The less sensitive to light the sensor will be- the more light is needed- the less noise in the photos and the higher the resolution
Camera: Shutter speed
Freezing motion needs higher shutter speed
The higher the shutter speed
the less time the curtain stays open- the less light available to the sensor- the more action is frozen
The lower the shutter speed
The more time the curtain remains open- the more light gets to the sensor- more motion is captured
Will produce blur
Shutter speed under 1/60
Freezes motion
Shutter speed over 1/250
Lens: Aperture
Low number, more light, less depth/ high number, less light, more depth
The lower the f/stop
The larger the opening in the lens (more incoming light)- the less depth of field- the blurrier the background
The higher the f/stop
The smaller the opening in the lens (less incoming light)- the greater the depth of field- the sharper the background
