Digital Photography Flashcards
What are the camera settings?
M-Manuel
P-Program
S-Shutter Priority
A-Aperture Priority
What does Manuel in the camera settings mean?
You are in control of adjusting each setting. (Shutter Speed, Aperture (f/stop) ISO)
What does Program in the camera settings mean?
The camera controls the settings. (Shutter Speed, Aperture (f/stop) ISO)
What does Shutter Priority in the camera settings mean?
You are in control of the Shutter Speed, the camera controls the Aperture (f/stop) and ISO
What does Aperture Priority in the camera settings mean?
You are in control of the Aperture (f/stop), the camera controls the Shutter Speed and ISO
Tell me about Aperture:
- Measured in “F-stops”
- Controls how much is in focus (“depth of field”)
- Affects amount of light coming into camera
Tell me about Lens Opening:
- The larger the opening, the greater amount of light is allowed into the image sensor
- The size of the lens opening is measured by F-stops (The larger the F-stop, the smaller the opening)
What is the order of the F-stops?
The F-stops are as follows: F 1.4 (most light) F 2 F 2.8 F 4 F 5.6 F 8 F 11 F 16 F 22 (least light)
What is Shutter Speed and what does it do?
- The rate the shutter opens and closes
- Affects amount of light coming into camera
- Impacts risk of blur in a photo
- Measured in fractions of a second (1/60, 1/200, 1/800)
Tell me about Shutter Speed:
- The time for which film is exposed to light is controlled by the shutter speed
- The faster the shutter speed, the shorter the duration of film exposure, and the less light reaches the film
- A dimly lit subject requires a slower shutter speed than a brightly lit object
What are the shutter speed settings?
The following are shutter speed settings: (fraction of seconds) 1 (most light) 2 4 8 15 30 60 125 250 500 1000 (least light)
Tell me about ISO:
ISO: Image Sensory Absorber
- Sensitivity to light
- Impacts how bright a picture is
- Measured in hundreds (100, 200, 400, 800, 1600)
- The higher it is, the brighter the photos are
- The higher it is, the more noise in a photo
Tell me about ISO speed:
ISO speed: A rating of a film’s sensitivity to light. Though digital cameras don’t use film, they have adopted the same rating system for describing the sensitivity of the camera’s imaging sensor. Digital cameras often include a control for adjusting the ISO speed; some will adjust it automatically depending on the lighting conditions, adjusting it upwards as the available light dims. Generally, as ISO speed climbs, image quality drops.
What is the difference between a point-and-shoot camera and a DSLR camera?
DSLR- Digital Single Lens Reflex Camera: A camera that has removable lenses, that has a reflex mirror which allows live optical viewing through the lens taking the image. DSLR’s use a mirror that allows you to see the image you’re about to shoot through the view finder- when you take the shot the mirror flips up, allowing the image sensor to capture the image
Point-and-Shoot Camera: A simple, easy to use camera that allows the user to simply point at the subject and take the photo. The camera automatically calculates shutter speed and aperture values. Some P&S cameras, however, allow the user to adjust the shutter speed and aperture
What are the composition concepts:
- Rule of Thirds
- Backgrounds
- Lines; Geometry
