Learning your equipment sounds really easy until getting out into the field and realize, “I never thought about how to evaluate the amount of light put out by my light source!” Now this opens up a new area for questions and learning. “How sensitive is my camera to light?” “How does my camera’s sensitivity measure against its shutter speed?” “How does my camera’s sensitivity to light change with each aperture stop?”
Some answers can be “too simple” or rather purely informational without direction as to the application of the information. So in this post I hope to bring you two options explaining their application to the best of my ability.
Option 1: Light meter. Handheld light meters get more expensive the fancier features they contain. There is an excellent article by B&H Photo on learning about handheld light meters and information to help you choose the appropriate light meter for you. Most digital cameras are equipped with light meters (if you will remember the light meter I referred to in my first post on “Learning Your Equipment”). However, there is one key difference between a handheld light meter and a light meter in your camera.
The difference in light meters held in your hand or in your camera is this, the meter’s location. Now what will help you most? A light meter showing you the amount of light surrounding your subject or the amount of light around your camera? Answer: You want to know the amount of light around your subject. That makes it a little difficult to measure the light around your subject with your camera when it is more efficient to have it set-up on your tripod.
Option 2: Requires a lot of experience and a trained eye and mind. Using your own vision to estimate the light around your subject is cheapest and builds your skill. I am still tweaking my own skill, so I am not much practical help at this time. Some practical pointers to come in Fridays post.
