Video for Photographers

Video For Photographers: Shooting with a DSLR
CH 1

Understanding resolution for video

·       Resolution has nothing to do with megapixels

·       Photography can change resolution at will

·       Video has two resolutions: 1080 HD, and 720 HD

·       1920x1080 pixels = 2 megapixels

·       1280x720 pixels = 1 megapixel

Choosing a video frame rate

·       Simple= 30 frames per second (traditional)

·       True film look= 24 frames per second

·       For sports, to smooth motions= 60 frames per second

 

CH 3

Understanding the challenge of shutter speed

·       Frame rate divide by 30 (for 30 frames per second) your slowest shutter speed would be 1/30

·       This would mean 1 second of video with no gaps

·       normally for video, you will be choosing a shutter speed between 1/30th and 1/90th of a second.

·       Some say ideal shutter speed is 2 times the frame rate. That would mean if you are shooting 30 frames per second, you would choose 1/60th of a second for the shutter speed

           

Getting the right exposure

·       Use scale at bottom of camera to show under/over exposed scale

·       Use histogram to check for proper exposure

·       Zoom lenses are not very fast, but lets in lots of light

·       Get better exposure by: setting your ISO, using a neutral density filter, and looking into maybe using fast prime lenses
