Join Alan Chung's workshop to explore the evolution of DSLR video, from the introduction of Nikon D90 to Canon 5D Mark II, and learn about DSLR video basics like aperture, shutter speed, and ISO settings. Discover the pros and cons of using DSLRs for filmmaking!

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
