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

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

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).
