Shutter speed/f-no./ISO: Where's the elegant balance?

[table1349]

There are trade-offs in everything. Here are the ones associated with the three methods of getting more light:

high ISO - introduces noise, especially at the highest ISO setting on your camera, and sometimes the one below that.

slower shutter speed - doesn't freeze subject motion or camera shake as well

lower f number - less depth of field and possibly if you are near wide open, less image quality

So, you pick your poison for the particular situation and go from there!

Its as simple as that.

Yep, the physics of the exposure triangle are actually quite complicated, but putting those physics to work are really not that difficult.
