That effect mimics the shallow depth of field
of a proper big camera - but the iPhone camera can't do it for real because the laws of physics don't allow it.
One of the problems of photographing small things is the very limited depth of field
that a macro lens will provide, even stopped down to a small aperture," Hawkridge explains.
Depth of field
is an important consideration in photography: it is the area in front of and behind the point of focus that is also in acceptable focus, and the shorter the lens focal length, the greater the depth of field
The Section 2 image samples show the same image clicked in four different modes - normal auto, HDR, Depth of Field
and Super Res.
It's hard to resist achieving a very cinematic look at 24 fps with a very shallow depth of field
, for a fraction of the cost.
Here is a question for the newbie: If you find that 4mm of depth of field
is too narrow (or small) to work with, is it practical to research for even narrower (say, 2mm) depth of field
As a result, simple eyes generally can't focus very close, and they tend to have quite a shallow depth of field
That particular aperture setting gives decent depth of field
in most situations.
Peep size affects the depth of field
you will experience while aiming.
A lens setting yielding a large depth of field
will show everything from foreground trees to distant mountains clearly.
This technology is ideal for applications that require a large depth of field
or when refocusing is needed after a product changeover.
The full family of Xenon scanners has been upgraded with extended depth of field
, improved data matrix and mobile phone reading, adjustable illumination, Bluetooth HID keyboard interface and optional laser aimers.
