What is point of view and why does it matter?
Something I see a lot when I scroll through social media is that parents take photos of their children from their own height. This makes complete sense, because the most natural thing to do is just to put the camera or phone in front of your face, point it slightly down at the child or children in front of you and take a photo. What that does though if the child is a lot smaller than you (and close to you), is that you are showing them from slightly above and making them appear smaller or compressed.
How do we change this?
If you go down to the child's eye level, ie so that you and the child are eye to eye to each other, the angle at which you see the child changes and your photos show the world from their perspective. Depending on the size of the child, you could crouch or kneel down or, for babies, hold the phone or camera close to the ground, or lie on your stomach. Alternatively, you could raise the child up - for example they could stand on a climbing frame - so they are at your eye level.
It might seem odd to start with, but it's something you get used to and do automatically really quickly. While it is just a little thing to change, it will make a big difference to your photos. They children in the photos will look more in proportion and instead of looking down at them, you are showing them in their world at their level.
Have a look at some examples of photos taken at about the child's eye level:
What else can we do with this?
Photography is all about breaking the rules and trying different things! You can change the point of view for different effects. For example, try taking photos from above (I was balanced on our dining table for the one below!) or you can make the child look more heroic or in charge of their world by taking a photo from lower down.
