Concerns when shooting Depth of Field

• Main subject should be in focus

• If surrounding areas are important to subject’s relativity, use a LONG depth of field

• Key part of the camera which controls depth of field…

3 types of Depth of Field

• Short/Shallow

• Medium

• Long/Great

>> 0 >> 1 >> 2 >> 3 >> 4 >>

Short Depth of Field

• At f/2.8 only the focused subject will be sharp; foreground and

background won't. • This effect may be very

dramatic with portraits and is known with the

japanese word "Bokeh".

Medium-Depth of Field

• Many photographers prefer very sharp images.

• End result: sharper image

>> 0 >> 1 >> 2 >> 3 >> 4 >>

Long-Depth of Field• Smaller apertures (f11)

everything in the scene

will be very sharp • Many lenses have a

so-called sweet spot where the lens reaches the maximum sharpness

• (in many cases at f/8 or f/11).
