FIle Formats

1. I have used JPEG
2. Rastor images data describes the characteristics of each individual pixels and vector formats contain a geometric description which can be rendered smoothly at an desired display size.

JPEG
1. lossy
2. small pictures and on screens
3. yes

TIFF
1. lossless
2. working format for editing digital images
3. some can, some can't

PSD
1. either lossy or lossless
2. photoshop
3. no

DNG

Lossy vs. Lossless

RAW file advantages
  • Gives you more control over how your images looks
  • can fix mistakes such as white balance or exposure
  • higher dynamic range
RAW disadvantage
  • have to get different software for your computer
JPEG file advantages
  • higher in contrast and sharpness
  • can print immediately
  • can take pictures faster since they save quickly straight into the camera
JPEG disadvantage
  • not as much control in editing
1. A RAW file retains all the data from the photo without compressing it.
2. A RAW file enables a photographer to edit white balance, contrast, highlights, shadows, colors, and saturations.
3. Some factors that a photographer must consider when deciding to shoot in RAW is that the files are much larger, and you may have to convert the images to JPEG.
4. An aspiring photographer needs to know how to work with RAW files because it has greater flexibility and processing options.

Aperture, Shutter Speed, ISO

Aperture:
 F2.8

F22

1.We should relate should relate the aperture to the pupil.
2. The smaller the Aperture the higher the F-stop, the higher the Aperture the lower the F-stop.
3. Aperture impacts depth of field by having a large F-stop will bring all foreground and background in focus, and a smaller F-stop will only focus on an object in the foreground or background, not both.

Shutter Speed:
 High Shutter Speed

Low Shutter Speed

beginning of the day
a)1/125
b)1/125, 1/200
c)1/500, 1/750
d) 1/500

f) 1/750

night
a)1/30

Aperture Priority: You set the lens aperture but the camera automatically sets the shutter speed.
Shutter Priority: You set the shutter speed but the camera automatically sets the aperture.Manual: You set the shutter speed and the aperture.

ISO:
 ISO 200

ISO 6400


1) The advantages of shooting at a higher ISO during a sporting event is because there is not as much light and you still want to freeze the image.
2) You should use a low ISO when there is plenty of light or if your camera is on a flat surface or tripod.
3)You should use a high ISO when there is not as much light or you want to get ultra fast shots.

DSLR:
Aperture Settings: 2.8, 4, 5.6, 8, 11, 16, 22
Shutter Speed Settings: 1 sec, 1/60 sec, 1/4000 sec
