To the uninitiated, the idiot mode functions on their newly acquired DSLR camera could be viewed as a real feature that will transform their photography. The idiot modes are the little face, landscape scene, runner, or flower on the mode dial on a camera. If you really aren’t going anywhere in your photography then they will assist in shooting average photos. My advice though, is to take a black permanent marker and blot them out. They are not going to help you as you learn photography.
The nice thing about pro cameras is that these options have been removed, and there are no longer these choices. So you’re forced to use the creative modes of Aperture Priority, Shutter Priority, and Manual. The reason to use these modes is answered in the following points.
1. Aperture Value (A or Av on most cameras)
By choosing aperture value you get control of—you guessed it—your aperture. You choose the aperture and the camera gets to choose the shutter speed. This gives you complete control of depth of field, (i.e. how much of the photo is in focus in front of and behind the subject you are focusing on). You can blur out the background or have a sharply focused landscape from foreground to the background. You have control of the size of the aperture, which controls depth of field and the amount of light allowed through the lens. Now the problem you’ll experience when controlling the aperture is that the camera has no idea of fast movement in the scene. So it will choose a shutter speed that doesn’t necessarily achieve the effect you intended. So what do you do? Look at point 2.
2. Time Value or Shutter Priority (S or Tv on most cameras)
The problem you have experienced needs to be corrected by choosing the shutter speed and allowing the camera to select the aperture. You might want the action blurred, so a slower shutter speed is selected, or perhaps you want the action or movement frozen and in sharp focus so a fast shutter speed is selected. All nice and simple and for most of the time a really creative shot.
Now another issue raises its head. What happens when you want to select both the aperture and the shutter speed? Say, a frozen movement with a shallow depth of field? You can’t rely on the camera to get it right, so what do you do? Look at point 3.
3. Manual Mode (M on most cameras)
A whole chapter can be written on manual mode, but the bottom line is that it gives you the control you need over all aspects of the image. The camera meter will give you a recommended shutter speed and aperture, but you may want a slightly different effect, so, choose the aperture and shutter speed you require. But, by doing this there might not be enough light and you are left with a dilemma: a bad exposure.
That’s where the exposure triangle comes to your rescue. The third element of exposure after aperture and shutter speed is ISO. By increasing the ISO level you will make the sensor more sensitive to light thereby adding the necessary light to the image and allowing you to use the aperture and shutter speed of your choosing.
I just want to stress that this is a very simplified look at taking control of the creative controls of your camera. As you learn digital photography, take time to explore and experiment with each of these controls. Once you master them you will never shoot on automatic again. The freedom it gives you to create the perfectly exposed image will change you forever. Happy shooting!
