Quick Tips
3. Improving Optical Performance
Stopping aperture down increases depth of field, making the |
|
|
foreground and background sharper. Stop aperture down |
|
|
too far, however, and diffraction will actually cause the image |
|
|
to lose definition. The effects of diffraction are partly influ- |
|
|
enced by the size of the pixels in the camera image sensor, |
|
|
but with the D800/D800E’s high resolution the effects gen- |
|
|
erally become noticeable around f/11. When you need more |
|
|
depth of field, don’t just immediately stop the lens all the way |
|
|
down; instead, look for the aperture that offers the best bal- |
|
|
ance between sharpness and depth of field. In the examples | f/8 | f/11 |
on this page, you can see the grid lose definition as aperture |
|
|
is stopped down past f/11.
f/16 | f/22 |
