13. Ultra HD
๏ UHD is a resolution of 3840 pixels × 2160 lines with an aspect ratio of 16:9
๏ It’s image totals 8.3 megapixels
๏ It’s one of the two resolutions of ultra high definition television targeted
towards consumer television
๏ UHD has twice the horizontal and vertical resolution of the 1080p HDTV
format, with four times as many pixels overall
14. Digital Cinema Initiative 4K
๏ The Digital Cinema Initiatives consortium established a standard
resolution of 4096 pixels × 2160 lines with an aspect ratio 256:135 for 4K
film projection.
๏ It’s image totals 8.8 megapixels
๏ This is the native resolution for DCI-compliant 4K digital projectors and
monitors.
15. Digital Cinema Initiative 4K
๏ Pixels are cropped from the top or sides depending on the aspect ratio
of the content being projected.
๏ DCI 4K does not conform to the standard 1080p Full HD aspect ratio
(16:9)
๏ 4K digital films may be produced, scanned, or stored in a number of
other resolutions depending on what storage aspect ratio is used In the
digital film production chain.
16. Streaming Video
๏ YouTube and Vimeo allow a maximum upload resolution of 4096 × 3072 pixels
๏ This means 12.6 megapixels if using an aspect ratio 4:3)
๏ High Efficiency Video Coding should allow the streaming of content with a 4K
resolution with a bandwidth of between 20 to 30 Mbps.
19. What are the Benefits of 4K?
๏ Footage is “Future-Proofed”
๏ Drastically Improved Image Quality
๏ Consumer Demand
๏ Increased Distribution Options
๏ Easily Down Converted – Universal Master
21. For Your Consideration
๏ Film has resolved at 4K for nearly100 years
๏ Companies like RED and more recently Blackmagic
Design have pushed 4K to becoming a standard with
wider adoption by media professionals
๏ Broadcasters are dragging their feet on 4K due to
costs involved.
22. For Your Consideration
๏ Cameras Change five times faster than our
editing tools
๏ Remember that RED is only 10 years old.
๏ Tapeless Production is only 13 years old
๏ Raw or Log workflows always generate more data on
set and more work in post
23. For Your Consideration
๏ Bigger image equals more costs
๏ We prefer flexibility in our workflow
๏ Add 4K when budget allows, longevity is important,
or recomposing the frame is needed
๏ Moving 2-3 Terabytes of data per camera, per day, is
now common

58. Internal Recording
๏ Newer models offer internal 4K recording
๏ When using a camera rig or usage requires taking advantage of
compact size of camera
๏ Less chance for error
๏ Less power needed
๏ Embraces compact size
59.

๏ Pay close attention to the class of card and your
needs for shooting
๏ Carry a mixture of brands and sizes
๏ SD 5.0 Memory Cards will support 8K, 3D, and 360°
video
61.
62. External Recording
๏ When frame rates higher than 30 fps at 4K resolution
๏ With older cameras that don’t offer internal 4K recording
๏ Models like Atomos offer external monitoring, focus assist, waveform
๏ Can record deeper color depth (10 bit)
๏ Records Uncompressed 4K and audio (internal is always 4:2:0)
๏ Longer record times, on affordable media like SSD drives
๏ Records to familiar codecs like Pro Res, Avid DnX
63.

๏ Records 4K (3840x2160) up to 30 fps
๏ Records 1080p up to 120 fps
๏ ProRes and DNxHD 10-Bit, 4:2:2 Encoding
๏ 12G-SDI Input and Loop-Output
71. The Role of a Low Pass Filter
๏ No filter is good for stills, landscapes
๏ Filter blurs the image at the pixel level
๏ Landscape photographers don’t need them as much, as moire occurs in fine, repeated
patterns…less likely to encounter this in landscapes
๏ Some sensors minimize color moire and aliasing without filters
๏ Post-processing can correct some of this (spot correcting)
๏ New to Mirrorless cameras to not have AA filter
๏ When the pixel count is high enough, Mirrorless cameras can do away with the AA filter
72.
73.
74.
75. The Role of a Low Pass Filter
๏ NO FILTER
๏ Canon 5DS-R removes the low pass filter
๏ Sony RX1R II has a VARIABLE low pass filter
๏ Sony a7R II has no low pass filter
๏ LOW PASS FILTER
๏ Sony a7S II has low pass filter
๏ Panasonic GH4 has low pass filter
87. Impact of Light and Motion on Focus
๏ If you’re shooting a lot of motion, pay close attention to
both the amount of light as well as the quality of light
๏ The less light that’s available, the larger an aperture
you’ll have to use in order to record a properly exposed
image.
๏ This means that your depth of field will decrease and it
will be much harder to keep your subject in focus.
๏ If you or your subject are moving, it get’s even more
tricky
88.
89.
90.
91. The Window
๏ Imagine your camera is a window with shutters that open
and close.
๏ Aperture is the size of the window. If it’s bigger more light
gets through.
๏ Shutter Speed is the amount of time that the shutters are
open. The longer they’re open, the more that comes in.
๏ Inside the room and are wearing sunglasses. Your eyes
become desensitized to the light that comes in (like a low
ISO).

with the camera/lens
๏ Adaptors that convert full frame to APS-C
๏ Adaptors that convert 4/3 to Full Frame
๏ Lens support, weight, rail support
๏ Some adaptors offer increased stop (speed booster)

142. When To Use Prime Lenses
๏ Most DPs choose primes both on feature films as
well as independent projects for two main reasons:
speed and sharpness.
๏ A quality prime lens with a wide aperture of f/1.2 to
f/2 will allow you to shoot in existing light or low-
light environments more easily.
๏ Primes are universally faster than a zooms due to
the way they are manufactured.
143. When To Use Prime Lenses
๏ Prime lenses have less moving parts, and fewer
elements than zoom lenses. The result is a sharper
image.
๏ Primes are great for videos where you have control of
the environment. You are stuck with the focal length
๏ If you can block out any movement in the scene in
advance, control the lighting and want that nice short
DOF that these lenses deliver, then prime lenses are a
good choice.
144. When to Use Zoom Lenses
๏ When you need to change focal length quickly and/or
you need the versatility of those different focal lengths
๏ Zooms are generally slower than a fast prime, so you’ll
need to raise your ISO higher to match the exposure
๏ Many documentary shooters use zooms because there
isn’t any way to stop the event or subject just to
change lenses
๏ Able to go from a 50mm standard shot of the
interviewee to a 200mm close-up
145. Adapting the 4K
Camera with a Cage
or Rail System

EA_photo
150. When to Use a Cage
๏ Sometimes you need to build camera out with a
cage for accessorizing
๏ External recorders, monitors, viewfinders, lens
control motors , cable locks
๏ Protection from impact
๏ More attachment points for rigging shots
157. Powering the Camera
๏ When shooting video, your camera will need much
more power than you usually use when just
shooting stills.
๏ First, you’ll be using the Live View function of the
camera – which means powering the LCD
continuously
๏ Second, to record video, your camera’s processors
and memory card are working all the time.
158. Powering the Camera
๏ Your camera’s default settings for the live view mode
includes shutting it off after a couple minutes. Leave
this as is.
๏ It’s essential to have additional batteries with you
when shooting video.
๏ Pack five batteries per shooting day for each camera
body.
๏ If charging batteries is an easy option, you can get by
with less (3 per camera)
159. Using a Battery Grip
๏ Two batteries are in use.
๏ Sometimes one is contained in the grip and one in the
camera body. Other times, two are in the grip itself.
๏ This added power is great for shooting video because
you’ll be using the live view mode on your camera all
the time.
๏ A battery grips often allows you to change batteries
quickly since the battery door is located on the rear
or side of the grip.
160. Tethered Power
๏ If you are in a studio or other location where AC power is available for a
longer period of time, an AC power adapter is a good alternative
๏ The only downside to them is that it limits camera movement, especially
if you are on a jib or dolly.
๏ We'll often power a camera with AC power for stationary shots (like
interviews), then switch to a battery when on the go.
162. Tether Tools Case Relay
๏ More cost effective than purchasing multiple proprietary
camera batteries
๏ Power sources are non-proprietary. Power your camera with
the same 5V battery you use to charge phones or tablets.
๏ Never need to charge camera batteries again. And never run
out power.
๏ Compatible with most Canon, Nikon, Sony, Panasonic, Fuji, and
Olympus cameras.
