Art Appreciation- Tuesday: • Make sure you have good notes on all the basic terms (on a blank sheet of paper), we will have an open-note quiz on this THURSDAY. • Make sure you are in class tomorrow- we will be doing a quick DARKROOM PROJECT. • Make sure you are current with projects, writings and journals/ websites. Pick up graded journals on the cutting board by my desk. • Keep in mind I am continuing to give 10 points for ATTENDANCE each day! Make up these points by coming in on a MONDAY or FRIDAY. THANKS!
What does the Shutter do? • Controls the amount of time light is allowed to strike the film • Controls motion
Shutter Speeds B 1 2 4 8 15 30 60 125 500 1000 2000 • B represents bulb, which refers to the use of flash bulbs with earlier camera models. • The 1 refers to a 1 second exposure, all other numbers are a fraction of a second. • Shutter speeds are in 1-stop increments, so a change in settings either halves or doubles the speed
Leaf Shutter • Located in the lens barrel • A function of the aperture mechanism but is also controlled by the shutter speed • Exposes the entire film plane as the metal leaves open
Controlling Movement • Camera movement- results when shutter speed is too slow to hold the camera steady • Subject movement- using a fast shutter speed to stop the action or a slow shutter speed to allow a blurring effect
Fast Shutter Speed • Stops action • Add an element of tension or dynamics
FAST SHUTTER SPEED – JUGGLING SHOTS NOTICE HOW OBJECTS ARE “FROZEN” IN THE AIR
Slow Shutter Speed • Showing movement in a photograph • Blurring the action in a scene
Panning • Allows the subject to remain in focus • Causes the background to appear out of focus because of camera movement • Gives the illusion of dynamic speed
Aperture description… • referred to as the opening inside a photographic lens. • The size of the opening in a camera lens regulates the amount of light that passes through onto the film or sensor. • Regulates the depth of field within a photo. • Aperture size is usually calibrated in f-numbers or f-stops. Each of this value represents one time the amount of light either more or less in quantity.
Depth of Field • Refers to the amount of the picture plane that appears to be in focus • May be referred to as shallow, medium, or wide 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. SHALLOW DEPTH OF FIELD:
With 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). WIDE DEPTH OF FIELD:
Exposure: the total amount of light allowed to fall on the photographic medium (photographic film or image sensor) during the process of taking a photograph.
How do you determine a correct exposure? 1. Control the exposure time and amount of light by adjusting the shutter speed and aperture settings
How do you determine a correct exposure? 2. Determine the sensitivity of the film • Sensitivity of film to light is referred to as film speed • Film speed is measured on a scale by ISO • The faster the film speed (larger the number), the more sensitive the film is to light • The slower the film speed (smaller the number), the less sensitive the film is to light
Fast Film speed The high sensitivity to light with the fast film speed produces a very grainy effect on the photograph.
Fast Film Speed -best for low light/ indoor due to the fact that it is more sensitive to light
Slow Film Speed The low sensitivity to light with the slow film speed produces a very detailed effect on the photograph. Little or no grains appear on the photograph.
Slow Film Speed -less sensitive to light, and does not produce the grainy look that a high film speed film would create.
Overexposure!!! Changing only the aperture setting by opening up with a correct meter reading results in overexposure- exposure to too much light. You don’t want this!
Underexposure Changing only the aperture setting by stopping down with a correct meter reading may result in underexposure- not enough exposure to light. You don’t want this!
Composition:the organization or grouping of the different parts of a work of art so as to achieve a unified whole.
Rule of Thirds • Subjects placed in the center of the photo often look stiff and motionless • Add interest by aligning your subject into one of the “thirds” of the photo
Framing • Brings the focus to the subject • Allows an object to act as a border around your subject • Creates perspective and shows depth
Leading Lines • Draw the viewer into the photograph • May be created by organic or man-made forms • Create depth and dimension
Simplicity • selecting uncomplicated backgrounds • avoiding unrelated subjects • moving in close
Color • May add intensity to an area of a photograph • May help create a mood or feeling • Can bring out the focus of the photograph
