Beautiful Portrait photography on Nantucket

Portrait photography on Nantucket has becoming incredibly popular with all the beautiful scenery and summer weather. Here are some tips of you are a Nantucket portrait photographer.

Using Programmed Auto 1. Set the Mode Dial to P. 2. Set the ISO. 3. Press the shutter button half- way. The camera displays the selected ISO in the viewfinder, plus the aperture and shutter speed required to give the correct exposure at that setting. Note: Pentax camera users should refer to their manuals as their cameras have more options in P mode. ISO (photographer sets ISO).

Program Shift In Program mode you set the ISO and the camera sets the aperture and shutter speed accordingly. Another feature that sets Program mode apart is that you have the capability of overriding the camera’s selected aperture and shutter speed settings.

This feature is called Flexible Program by Nikon. Canon, Fujifilm, Sony, Olympus, Pentax and Sigma call it Program Shift. To use Program Shift, push the shutter button half-way down. This tells the camera to take an exposure reading from the scene and choose an appropriate aperture and shutter speed. These are displayed in the viewfinder so that you know what they are.

If you want to override the camera’s settings, simply turn the dial to the left or right. You will see the aperture and shutter speed change together. You can keep turning the dial and the aperture and shutter speed will continue to change. They only stop when you reach the limits of the aperture settings of the lens or the shutter speeds of the camera. You will understand why when you think back on the lessons learnt in the previous section. If you change the aperture so that it’s wider, then it will let more light pass through the lens. You need to set a faster shutter speed so that the correct amount of light reaches the sensor. If you change the aperture so that it’s smaller, you need to use a slower shutter speed to allow the correct amount of light to reach the sensor. Why would you want to change the camera’s settings?

We have already seen how aperture and shutter speed affect the way the photo comes out. Creative photographers use both these settings to influence the look of the photo as well as obtain correct exposure. Learn more at and

Imagine that you are using your camera in Program (P) mode and the camera sets an exposure of 1/125 second at f8 and ISO 400 (above). But what if you would prefer to use a different shutter speed or aperture value? Simply turn the dial on the camera (left) to change the aperture and shutter speed settings in tandem. For example, if you wanted a slower shutter speed, you could change it to 1/60 second. The camera would set the aperture to f11 to maintain the correct exposure (below). Learn about photography at

Using Aperture Priority (A) Programmed Auto (P) is a useful mode (and its usefulness is extended by the Program shift function), but what happens if you want to set a specific aperture value for creative reasons? We’ve already explored some of the reasons why you might want to do this. You might choose to use a wide aperture when you take a portrait, to make the background go out of focus. Or you may want to use a small aperture to take a landscape photo where everything within the frame is in focus. Aperture Priority is a mode designed to let you do exactly this. It works very simply. Just set the Mode Dial to A (or Av if you have a Canon or Pentax camera), and use your camera’s dial to set the aperture. The camera sets the shutter speed according to the light levels and the ISO setting.
