How to Control your Depth of Field

• You will adjust your aperture or f-stop

  f/1.4, f/2, f/2.8, f/4,f/5.6, f/8, f/11, f/16, f/22, f/32

• You f-stop is written in numbers and some of them have decimals.

• LOW Apertures: Let in more light and create more shallow depth of field (f.8 or lower)

• HIGH Apertures: Let in less light and create deep depth of field (f.8 or higher)

Prime lenses. give the greatest depth of field.

Things to remember about PRIME LENSES

• THEY COST MORE

• DROPS TO APERTURES LOWER THAN 3.5

• DO NOT ZOOM IN AND OUT 

• CREATES MORE BOKEH OR DREAMY LOOK

• $200 TO $800, DEPENDING ON CAMERA AND MODEL
