COM 163 Lecture Notes - Lecture 1: 720P, Digital Single-Lens Reflex Camera, Progressive Scan
Document Summary
Golden mean: based on davinci"s work, fibonacci sequence, rule of thirds: it doesn"t match up exactly but it comes close, for mostly nature. Subject placement: foreground, middle ground, and background. Iris (part that lets the light in) and zoom affect the depth of focus. Depth of field: wide- camera is very close to the subject and zoomed out wide, narrow- camera is far from the subject and zoomed in tight. 1080i: skips every other line, eye- interlace scan, even lines field 1, odd lines field 2, field 1 + field 2 = complete frame. 1080p: scan all lines consecutively without skipping. Standard resolutions: ntsc 525 lines. Consumer camera- cell phones, i pads, handy cam (one in every pocket) Pro-sumer camera what we will use in this class manual/automatic (portable television camera) Dslr cameras excellent video, but limited audio interchangeable lenses (great, clear pictures, cameras photographers use) Pro cameras interchangeable lens and manual controls pro audio.
