Set the shutter speed to 1/500 or 1/1000. Capture a range of subjects in motion creating a minimum of 15 photos that freeze the motion.
Blurring motion: use a tripod. Start with a shutter speed of 1 “. If your photos are too bright look for a darker place to shoot. Combine something moving and something that is still and sharp in every frame. You can tell a short story like Duane Michals or create a minimum of 10 photos that contrast blurred motion with a sharp environment.
Put the final 25 photos in an album on Flickr. Send your best one or two of each category to the class group.
Shutter Speed is the length of time that the sensor is exposed to light to create the photograph. It is measured in seconds or fractions of a second.
The full stops for shutter speed are: 30â, 15â, 8â, 4â, 2â, 1â, . sec, ., 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000
Doubling the time, doubles the amount of light that reaches the sensor.
When shooting with a cameraphone and the Lightroom Photoshop app, you can set the shutter speed of your cameraphone between 1/10,000 and 1/4 sec.
A good rule of thumb when shooting with a camera is: Any shutter speeds slower then 1/60 require the use of a tripod. When shooting with a cameraphone, you will need a tripod to shoot at 1/15 or slower.

Capturing of Motion
Your choice of shutter speed will change the way motion is captured in the photograph.
Frozen Motion-Motion is stopped and captured in the frame with a fast shutter speed.

How to freeze motion:
Use a shutter speed of 1/ 500, 1/1000 or faster.
Blurred motion-moving elements blur with a longer shutter speed.

How to blur motion:
Use a slower shutter speed – 1/4 sec to 30″ or even longer
Direction-if the subject moves parallel to the picture plane there is more visible movement than if the subject moves toward or away from the camera.
Focal length-a subject will appear blurrier when photographed with a telephoto lens than when photographed with a wide-angle lens.
Timing
The exact moment that you take the picture is as important as how long the shutter speed is. This is often called:
The Decisive Moment: A term coined by Cartier Bresson- “the simultaneous recognition, in a fraction of a second, of the significance of an event as well as the precise organization of forms which gives that event its proper expression.”
Photographing outside during the day in good light, take a minimum of 30 photos where there is something in the foreground and something in the background. Use shallow depth of field so either one or the other is out of focus.
If you are working with a camera phone, all of your shots will be close ups. Please for this homework, do not use an app like focos or portrait mode.
When working with a camera phone the best way to achieve shallow depth of field is to get very close to the subject with some actual space between the foreground and the background.
Put your 30 photos on an album in Flickr. Send your single best photo to the group.
Camera Phones and Depth of Field
Camera phones have a fixed aperture. For example, the aperture of the iPhone 7 is f1.8. This is one of the things that makes cameraphones so good in low light. You might think this wide open aperture would make it easy to get shallow depth of field with a cameraphone. However, the other factors involved make it quite challenging to achieve shallow depth of field with a cameraphone.
Camera to subject distance is the factor that gives you the most control of depth of field when working with a camera phone. To create shallow depth of field bring the camera as close as possible to the subject. Allow for some actual space behind the subject
Focal length is the distance between where the light converges in the lens and the sensor and there just isnât that much space. Even for cameraphones, we use the size of 35 mm film as the standard when discussing focal length. So the iPhone 11 has three lenses that are the 35 mm equivalent of 13mm, 26mm and 52mm. Earlier phones with one camera have one focal length. If working with a camera phone with more than one lenses, use the telephoto choice (highest number) to create shallow depth of field.
Depth of Field-The distance between the nearest and farthest points that appear in acceptably sharp focus in a photograph. Depth of field can be shallow or extensive. While the term includes the word depth, depth of field refers to focus.
Shallow depth of field is commonly used in portrait photography to separate the subject from the background and in food photography.

Extensive depth of field is often used in landscape photography and photojournalism.

The depiction of space
Perspective-the representation of a 3-dimensional space on a 2-dimensional surface by converging lines, diminishing scale and/or atmospheric perspective.
Aperture is the size of the opening that allows light to hit the cameraâs sensor when the photograph is taken.
Aperture values are expressed in numbers called f-stops. A smaller f-stop number means more light is coming into the camera and will create shallow depth of field. A larger f-stop number will let less light into the camera and create extensive depth of field.
The full stops for aperture are: F2, f28, f4, f5.6, f8, f11, f16, f22, f3
Focal Length is the distance from where the light converges in the lens to the sensor. If it is a short distance then the lens is a wide angle lens and shows a lot of the scene. If it is a long distance, the lens is a telephoto lens and it magnifies the scene. Wide angle lenses create extensive depth of field while telephoto lenses create shallow depth of field.
Camera-to-subject distance is how far the subject is from the camera. If everything is far from the camera, it is easier to achieve extensive depth of field. If the main subject is very close to the camera and the background elements are far from the camera, it is easier to achieve shallow depth of field.
It is the small size of the sensor that makes cameraphones so good at achieving extensive depth of field. It is also the main reason it is so hard to get your cameraphone to achieve shallow depth of field.Sensor size-the smaller the sensor the easier it is to achieve extensive depth of field. Bigger sensors allow for shallow depth of field.
Bokeh-Bokeh comes from the Japanese word boke (ăă±), which means “blur” or “haze”, or boke-aji, the “blur quality.” Bokeh is pronounced BOH-KÉ or BOH-kay.
