SHUTTER SPEED

•CONTROLS THE AMOUNT OF TIME LIGHT HAS TO ENTER THE CAMERA AND EXPOSE THE FILM.

•SHUTTER SPEEDS ARE MEASURED IN FRACTIONS OF A SECOND

SHUTTER SPEED SCALE

APERTURE/F STOP

•CONTROLS THE AMOUNT OF LIGHT THAT ENTERS THE CAMERA AND EXPOSE THE FILM.

•“F” STANDS FOR FRACTION

•F1.4    2.0    2.8    4    5.6    8    11    16    22

F STOP

• THE F-STOP IS THE FOCAL LENGTH OF THE LENS DIVIDED BY THE DIAMETER OF ITS OPENING.

• EACH CONSECUTIVE F-STOP HALVES THE OPENING OF THE PREVIOUS.

• FOR EXAMPLE, A 50MM LENS WITH ITS F-STOP SET TO F2 MEANS THAT THE OPTICS INSIDE THE LENS CREATE A DIAMETER EQUIVALENT TO 25MM.

DEPTH OF FIELD

•THE DISTANCE BETWEEN THE NEAREST AND FARTHEST OBJECT IN A SCENE THAT APPEARS IN ACCEPTABLE FOCUS.

CAN BE CONTROLLED THREE THINGS

•FOCAL LENGTH OF LENS: THE SHORTER THE DISTANCE FROM THE LENS TO THE FILM, THE GREATER THE DEPTH OF FIELD

•50 MM

CAN BE CONTROLLED THREE THINGS

•DISTANCE OF OBJECT TO THE LENS: DEPTH OF FIELD INCREASES THE FARTHER AWAY THE SUBJECT IT FROM THE CAMERA. A LENS FOCUSED AT 20 FEET WILL PROVIDE GREATER DOF WHEN FOCUSED AT 10 FEET.

CAN BE CONTROLLED THREE THINGS

•F-NUMBER: DEPTH OF FIELD INCREASES AS THE LENS APERTURE BECOMES SMALLER

GREAT DEPTH OF FIELD

•SMALL F STOP – F/16, F/22

•BACK AWAY FROM YOUR SUBJECT MATTER

•USE TRI-X (LESS LIGHT, FASTER SHUTTER SPEED, OUTSIDE)

SHALLOW DEPTH OF FIELD

•LARGE F STOP – F/2.8, F/2

•MOVE CLOSER TO YOUR SUBJECT MATTER

•USE PLUS-X (MORE LIGHT, SLOWER SHUTTER SPEED, OUTSIDE)

ASSIGNMENTS

• HALLWAY ASSIGNMENT• GROUPS OF 4

• GREAT DEPTH OF FIELD:• LANDSCAPE, SEASCAPE ETC.

• SHALLOW DEPTH OF FIELD:• CHOICE BUT NEED FOR, MID AND BACKGROUND
