Now that you have learnt about Shutter Speed, Aperture and ISO in part one of this tutorial, it is time to explore the semi-automatic modes Aperture Priority (Av), Shutter Priority (Tv), Program AE (P):

  • Aperture Priority (Av),  restricts the user to adjusting the aperture and adjusts the others automatically.

  • Shutter Priority (Tv), restricts the user to adjusting the shutter speed and adjusts the others automatically.  

  • Program AE (P), sets the shutter speed and aperture to semi-automatic, allowing adjustment to the ISO. The shutter speed and aperture are chosen by the camera, but can be adjusted afterwards. This mode reduces the set-up time in scenarios where time is of the essence.   

Now that we have an understanding of each semi-automatic mode, lets explore how we can use them to our advantage!

 

Aperture Priority (Av)

Required Effect | Short focal length Solution | Large aperture size

Required Effect | Long focal length Solution | Small aperture size

In most cases aperture priority is used when a certain focal length is required or you are taking photos in extreme light.  A small comment has been added to each example photo to explain why aperture has been used.

 

Shutter Priority (Tv)

Required Effect | Capture unpredictable event Solution | Very long shutter speed (30 sec)

Shutter priority can be very useful in extreme light or when photographing moving objects. It is important to note that a shutter speed of at least 1/60 should be used when not using a tripod, to reduce the blur caused by a moving camera.

Program is mostly used for speed and ease of use. The following photos were all taken on the go, where the shortest setup time is needed.
