Lynda.com Notes
- Resolution is how detailed the image is...how many pixels
- Pixel- the unit to measure the image resolution
- HD is 1080x720....important....don't crop video
- 1080 HD -video image 1920x1080 pixels & 720 HD is 1280x720 pixels
- camera's mega pixels camera does not relate to resolution of the video of camera
- 1080 video = image size ~ = 2 megapixels & 720 video image size ~= 1 megapixel
- video frame rate- 30 frames/sec.......used to be 24
- for slow motion- need more frames to be smooth -about 60
- shutter speed in video diff from pictures
- high shutter speed-freeze frame-noisy
- 1/25 -simple movements......higher the speed weirder the look
- 1/30 - 1/90 is good
- ideal shutter speed is 2 times the frame rate
- manual exposure!
- when using RAW be more careful with exposure
- blinking light- checking correct exposure
- use the histogram
- check f-stops
- good iso-100 to 400, maybe to 800
- wide f-stops for limited depth of field? cut light & get a neutral density filter
- zoom lenses are NOT fast
- when shooting wide open with fast lens
