Re: Understanding Exposure
The first choice I make is f stop. Whether adding or subtracting. I want to use f stop to help determine DOF. Shutter speed I leave dependent on my selection of f stop. Depending on what I am doing I leave shutter speed alone or determined by the formula of the particulars involved in the exposure I am shooting.
I only use shutter speed as a prime motivator for lack of light or capturing motion. Other than these two elements, I use f stop to deduct or add. It's tough to explain as they are used in combination. Suffice it to say that my primary concern is depth of field. A secondary concern is how much light I need for certain areas or motion, as stated before.
Depth of field is primary in making a statement. F stop gives you this. Shutter speed is a compliment to depth of field. I always set my lens for DOF. I use a tripod to help if the shutter speed required is slower than I can adequately hand hold.
I hope this helps. I can only type words.
