Best camera focus techniques: 10 surefire ways to get sharp photos
Face Detection AF
This popular camera focus option is a form of automatic AF point selection found on most compact and compact system cameras – and even some SLRs in Live View mode (when the image is composed on screen).
It works by recognising face shapes in the scene and then prioritising the focus towards them.
Refinements on this camera focus system include Smile Shutter, which triggers the shutter to fire when the camera detects that the subject is smiling (it doesn’t work with every smile, but it can be very effective).
Some cameras can also be set to recognise particular faces in a crowd and focus on them. This is a very useful option for photographing your children at parties or events when they are surrounded by other kids.
When Face Detection AF is activated you’ll notice boxes appearing around peoples’ faces on the camera’s LCD to show that they have been recognised. Half-pressing the shutter release brings the faces into focus ready for the shot to be taken.
As you might imagine, Face Detection AF is extremely useful at parties and social gatherings when you want to get lots of people pictures.
