Homework: Notes on Chapter 6

- RAW files are captured at the largest size and without compression, so ISO is the only setting that will effect the image quality
- Image size determines how large of a print you can make
- Shooting with a larger image size gives you better quality if you need to crop later
- With JPEG you can choose how much compression you want
- Choose the best JPEG setting to produce the best quality files which are compressed the least
- Most consumer level digital cameras only offer JPEG
- TIFF is not compressed and JPEG is
- TIFF occupies more space
- RAW gives you greater flexibility than film
- ISO determines the camera's sensitivity to light
- On a digital camera you can change the ISO each shot while on film the whole roll of film has the same ISO
- You should shoot ISO 100 in sunlight
- A higher ISO setting increases the noise on the photograph
- If you are shooting indoors or at night without a flash you should use high ISO settings like 1600 and 3200
- Color temperature is used to describe the color of light
- Color temperature is measured in Kelvins (K) and it describes the relative intensity of red to blue light
- 1000 K, would be candlelight or firelight, while 10,000 K would be overcast skies, 5000 K would be typical daylight
- Some lightings produce illumination that's "warmer" or "colder"
- All digital cameras offer AWB (auto white balance). The camera finds the brightest point and assumes that this point is white. White balance can also be fine tuned in Photoshop.
- The aperture can be adjusted to let more or less light hit the sensor
