DSLR Camera Workshop Led by Alan Chung
How did DSLR video start? • Nikon first introduced the D90 that captured 720p 24fps • At first it was just a gimmick. No one really thought it would take off • News outlets asked camera manufacturers for an alternative/faster way to capture B-roll • Canon eventually jumped onto the bandwagon and introduced Canon 5D Mark II with a software update that allowed the use of video
Advantages of using a DSLR for Film Pros Cons DSLRs weigh less = shaky Highly compressed = quality loss Cannot record longer than 12 min at a time On board microphone is a joke. Must have external sound recorders/booms • DSLRs are cheap • Work with photography lenses that people have • Small size, easily swappable lens • Depth of field • Compressed small file formats
DSLR Video Basics • There’s only three things you need to know in order to operate a DSLR video camera • Aperture • Shutter Speed • ISO
Aperture • Aperture on DSLRs control how much depth of field occurs in the frame • We refer to these as f-stops • The higher the number the narrower the iris is • The lower the number the wider the iris is • Lower # = more lightHigher # = less light
Aperture (con’t) • Depending on the lens you are using, some can go as low as f/1.4 (super blurry) • At very high f/stops the entire image is clear • NOTE: The higher the f/stop number the more clear it is. If you have dust in your camera sensor it will show up as a dot on your film
Shutter Speed • Shutter Speed is a crucial element in DSLR video • Much like the principle concept in photography, shutter speed works the same way here • It allows you to pull off effects that you can’t do in traditional camcorders • Allowing you to achieve cinematic looks
Shutter Speed (con’t) • The higher you increase your shutter speed the more fluid the motion • General Rules: • Shooting at 24fps = 1/50th of a second • Shooting at 60fps = 1/200th of a second FPS x 2 = your shutter speed
ISO • ISO is used to increase the amount of light sent to the camera • The lower the ISO = less grain • The higher the ISO = more grain • For Canon 60d’s the sweet spot is usually around 100-1250 or so
