Shutter Speed, part of the Exposure Triangle
In my last post, I talked about by selecting the correct aperture, you could change the depth of field by selecting the correct aperture setting. I hope that you took your camera off of the shelf and tried it out. Today I want to talk about shutter speed. It’s basically how long the camera’s shutter stays open. To know what is the correct speed, you have to ask yourself a question. Is my subject moving or still? Generally if the subject is moving fast, use a fast shutter speed. If the subject is stationary, you can use a slower speed. The important thing is to learn how changing the speed will add action to the image. Using a slower shutter can create blur that can help show motion.
As you can see, you can add a sense of motion to your image by changing the shutter speed. If you speed things up, you will have to use a larger aperture or faster ISO to keep the exposure the same. If you slow things down, you will have the decrease the ISO or use a smaller aperture. “Remember to Make It Your Own”
