When filming, there are a number of reasons why people are excited about making their backgrounds blurry and the objects
sharp. A big reason is the popularity of it’s presentation. This technique results in a cinematic type of storytelling. And impacts greater on viewers.
Depth of Field
The secret is control of depth of field. Depth of field is the distance behind and in front of the focused object that results in a background. Higher priced consumer cameras on the market today provide greater options with depth of field, depending on the image sensor size.
SLR Cameras
For more depth-of-field control when making either videos or a photos, SLR cameras would be a better choice. Lens choice
is really about composition and angle, but that lens enters into the depth of field to provide you with more storytelling together with a camera
with digital sensors and face recognition. To go deeper, the lens apertures can narrow or increase depth of field.
Moving Subject
If your subject is moving, you are going to struggle to keep things in focus. As well as every slight camera move, up
or down or side to side, might have your object go out of focus as well. Perhaps digital sensors and face
recognition availability on a camera will assist with improving focus on moving objects.
