Sometimes some of the subjects in your shots are in focus, but other subjects that are a little closer or further away are out of focus.

This is an unwanted side effect of having what’s called a ‘Shallow Depth Of Field’.

Portrait Scene Mode

When you set your camera to the Portrait Scene mode, it makes some adjustments to the settings to ensure your main subject is in focus, and anything behind the subject is out of focus. This is normally very pleasing because it emphasizes your subject in the photo.

The focus is on the cake in this photo.

However, when you have multiple subjects and they are all at different distances to the camera (like the cake, and the two boys in this photo), you won’t often get the effect you desire. Either (as in this shot) the cake is in focus and the boy in the white top is slightly out of focus, or the boy will be in sharp focus and the cake will be blurry.

Basically with Portrait Scene mode set, the camera will focus on one thing. Only those subjects that are exactly the same distance away as what the camera focused on will also be in focus. Anyone who is further away or closer to the camera will be slightly out of focus. The actual range of who is in focus depends on a number of things including how far away from the camera your subjects are, and your aperture setting.

As you can see in this photo, the middle of the cake is in sharp focus, but the tee-shirt of the boy behind is out of focus, as is the front part of the cake.

To spot this, zoom in on your LCD screen after you take the shot. You see some parts of your image blurry that you want to be sharp.

Having Your Cake…

The easiest way to make all your subjects sharp is to move further away from them. This will increase the range of depths that are in focus. Don’t zoom in however, as this will negate the benefits of physically moving further away.

Another option is to change the Aperture setting on your camera. Here’s what I do:

1. Set your camera to Portrait Scene mode and take the shot.
2. Find out the Aperture your camera used to take the first shot. It will be a small number like F5.6.
3. Change the camera to “Aperture Priority Mode” rather than Portrait Mode. Usually marked as “AV”, this is a more advanced mode of your camera that gives you finer control
4. Set the aperture two settings higher (called one ’stop’ higher). If it was F5.6, set it to F7.1.
5. Take the shot again.
6. Look at the LCD screen of the shot. You should see more of your subjects in focus. If not all subjects are in clear focus, increase the aperture setting one more and try again.

I should warn you that changing the aperture like this also decreases the shutter speed (as less less light will be getting into the camera, so it compensates). If you are also in a low light environment you should take some steps to steady your camera as well.
