1. Eyes is the body part most related to aperture.
2. The smaller the aperture the more blurred, the bigger the aperture the more focused.
3. Aperture impacts depth of field by taking a 2d picture and make it look 3d by adjusting the aperture to what suits the setting.

F2.8

F16

Lossy Vs. Lossless

higher in dynamic range, complete data, more control

One disadvantage:
not as sharp

Three advantages of JPEG:
higher in contrast, sharp, able to be manipulated

One disadvantage of JPEG:
lower in dynamic range

1. Retains all the photo
2. Photographers can edit white balance, contrast, highlights, shadows, colors, and saturation.
3. Memory space, not every camera has the option, you cant convert jpeg to raw
4. Photographer would want to work on raw to dive deeper into editing skills.
