April Photo Tips; Shutter Speed and ISO

April 10, 2019  •  Leave a Comment

Understanding Shutter Speed: The shutter is the clicking noise you hear when taking a picture and the shutter speed is how quickly that shutter opens and closes. It controls how long your are letting light hit your sensor. Shutter speeds can be as fast as 1/4000 or 1/8000 of a second and as slow as 30 seconds (or 30” in camera). The faster the shutter speed, the fast the action you can freeze and the slower your shutter speed (or the longer your exposure) the more motion you will see in an image. If your image is over exposed (too bright) you want to speed up your shutter speed (higher number) and if it is under exposed (too dark) then it needs more time so you should slow down your shutter speed. Generally speaking, for high speed activities like sports, shutter speeds should range 1/1000 of a second and higher, children and pets should range between 1/250 of a sec and 1/1000 of a second, and adult portraits can range between 1/60 of a second to 1/250 of a second.

3 Ways to achieve a faster Shutter Speed (stop action):
1. Open up your aperture to let in more light.
2. Increase your ISO to be more sensitive to the available light.
3. Add more light to your scene if possible. (make it brighter). IMG_8062IMG_8062


ISO is referring to your cameras light sensitivity. It controls how sensitive your camera is to the available light. The ISO range starts at 100 (or 50 depending on the camera) and ends at 6400 (or 12,500 or 25,000 also known as High 1 and High 2 on some cameras). The smaller the number, the less sensitive you camera is, indicating that there is more available light and that your camera does not need to be as sensitive. The less available light there is (or the darker your scene) the higher (or more sensitive) your ISO would need to be. If your photo is under exposed make your ISO higher and if it is over exposed make your ISO lower.
