• Your camera‘s light meter decides what settings to use, e.g.

1/250 sec @ f 8OR1/60 sec @ f 4OR1/125 sec @ f 11etc….

…depending on the scene – how bright it is, how much white or black is in the overall composition, how sunny or cloudy, etc.

Each scene and each time of day will require a new exposure setting because the lighting conditions will be slightly different

Let’s say…

Your camera’s light meter says that

1/250 sec at f 8 is perfect for the scene you want to photograph…

…but you want to use f 5.6 instead…

Wait a minute….!

Why would I want to use f 5.6 instead of f 8 !!?

Depth of field

or

Shutter Speed?

Okay, so back to our original question….

What if your camera said that 1/250 of a sec at f 8 would let in the perfect amount of light for the scene you want to shoot….

….and you want to use f 5.6 instead….?

What should you do?
