RAW vs. JPEG

RAW Format

Advantages:

Complete Data

Higher in Dynamic Range

More bits of color

Disadvantage:

Lower Contrast

JPEG Format

Advantages:

High Contrast

Sharper

Immediately usable

Disadvantage:

Lower Dynamic Range

JPEG is the final image format that is ready to use.

RAW is the unchanged format of a photo.

1. RAW photos retain all the data, while JPEG images compress it.

2. With RAW photos, you can change the way the data is compressed before it becomes the final image.

3.You can't take as many RAW photos as you can JPEG photos, as RAW takes up more data.

4. RAW is useful when you aren't happy with your photos, or would just like to edit them in a way without losing data.

RAW

1. Learning editing skills

2. Taking photos for competitions

3. Making the photo suitable for selling.

JPEG

1. Taking quick photos

2. Taking A LOT of photos

3. Taking photos with older cameras

Free Shoot Planning

1. My plan is to do portrait photography.

2. My subject will be one of my friends (I haven't decided who yet).

3. I will shoot the photos outside, either near a wall or some plants

4. The photos will be shot outdoors

5. I will do these shots either during photography class or after school.

6. I will have to use artificial lighting, as I'm taking the photos inside on a background.

7. I will just need a tripod, since I'm taking the photos outside.

8. I will try to shoot at least five photos, but I will probably use more.

Sunny 16 Rule and Basic Exposure Constant

Sunny 16 Rule

In it’s simplest form, the Sunny 16 rule (or Sunny F/16 rule) states: On a bright, sunny day, the correct exposure for any middle tone subject is F/16 at the shutter speed nearest to the reciprocal of the film speed. For example:

ISO 100 = 1/100 second @ F/16 (bright)

ISO 200 = 1/200 second @ F/16 (partly cloudy)

ISO 400 = 1/400 second @ F/16 (cloudy)

ISO 800 = 1/800 second @ F/16 (very cloudy)

Equivalent Exposure

Different settings, same amount of light

Aperture and Shutter Speed Practice

F2.8 is best with 1/250 shutter speed

F4 is best with 1/125 shutter speed

F5.6 is best with 1/60 shutter speed

F8 is best with 1/60 shutter speed

F11 is best with 1/30 shutter speed

F16 is best with 1/15 shutter speed

F22 is best with 1/8 shutter speed

The background becomes more and more visible with each change in aperture.

F2.8 background isn't visible at all.

F4 background can only be made out slightly.

F5.6 background is slightly more visible, and you can make out the outlines of windows in the back. It is still blurry, however.

F8 is more visible, but still blurry.

F11 is more in focus. You can make out the entire building in the background.

F16 is more in focus. The couple is slightly blurred, and you can make out larger objects in the background.

F22 is the most in focus. The couple is slightly blurred, while you can now make out smaller objects in the background.

1. At slow shutter speeds, the movement of the people and the photographers are shown in the photo with the blurs.

2. A photographer would use a tripod or other tools to keep this problem in check.

3. I personally think that F5.6 with 1/60 shutter speed is the best. You can make out the background a little bit, but it keeps the subjects in focus.

Aperture, Shutter Speed, ISO

Aperture, Shutter Speed, and ISO

Aperture

Large Aperture

Small Aperture

1. Aperture can be best compared to the human eye.

2. The smaller the aperture, the larger the f-stop and depth of field. The larger apertures have smaller f-stops and a shallower depth of field.

3. As I said in Question 2, smaller apertures mean larger f-stops. This is for getting a good shot of a landscape. Larger apertures and smaller f-stops are for getting shots of one subject and blurring the rest out.

4. 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11, 13, 14, 16, 18, 20, 22, 25, 29

5. Smallest: 4.5. Largest: 29

ISO

Low ISO

High ISO

1. Higher ISO at a football game means better lighting and high shutter speed in order to take quick photos.
2. Use low ISO if you're outdoors during the day or a brightly lighted area.
3. Use high ISO when you're in a darker area or need to take a quick photo.
4. 100, 200, 400, 800, 1600, 3200, 6400
