- The Camera - "Focal Length and Frame Rate"

What is Focal Length? It is a measurement of mm that determines that distance between the center of a lens, along with its focus point.
What is the visual difference between a low mm lens and a high mm lens? Low focal length attains a shorter distance of view, along with a wider field of view. High focal length, on the other hand, attains a longer distance of view, along with a narrow field of view.



When do you use a lower/higher focal length? It is usually determined based on distance from the subject. Higher focal length can be used for subjects that are far away, whilst low focal length can be used for subjects nearby. Lower focal length may also be preferred if you'd like to capture a wide field of view that is close to you, whilst higher focal length can be used to bring more attention to something distant by zooming in. 


What is fps? It stands for frames per second and is used to determine how fast pictures are generated.
What is the advantage of using high frame rate? When using a high frame rate, more frames will be shown. This helps with slow-motion, as it makes the video look less choppy.
What is the "film/cinematic" look as it pertains to frame rate? 24/30 frames per second because it's what most movies use. There is enough time in between each frame to process in the viewers.

On The Spot Post-Production

On The Spot - Post Production This was definitely the most time-consuming project out of all of them this year. Besides that, however, it was a lot of fun getting to film things outside of the classroom and put some own creative spin on my own work.  Choosing The Right Music I was inspired by a few things from the videos shown in class. For one thing, I learned just how important sound is as the actual video itself. The sound is able to captivate the audience by following a certain tone that is easy for the viewer to understand. This was the hardest thing for me to do as it required a lot of thinking on my part in order to captivate this same feeling- I couldn't just slap any random music and call it a day. The search for the right kind of music was the most annoying part of this project for me because of this. I would play some songs found on bensound over my project, but none of them worked out. A silly thing I found out was that Jazz songs actually fitted well in the background

The Camera - Aperture & Iris

  - The Camera - "Aperture & Iris"                What is aperture?   It is essentially the "pupil" of a camera lens, in which the lens "open" and can be shrunk or enlarged in order to allow more or less light into the camera sensor.                  How does it affect exposure?   It changes the amount of light that is able to reach the camera sensor. Large, wide openings of the aperture will result in brighter photos because more light is passed. A smaller, tight opening of the aperture will result in darker photos because less light is passed. How does it affect depth of field?  A large aperture will yield greater background blur, whilst a small aperture will yield little background blur. How do you pick the right aperture for your scene?  When capturing photos in bright/dark environments, a smaller/larger aperture may want to be used since aperture affects exposure. This allows for less light on sunny photos, or more light on photos taken at night.

EQ

  - Sound Design - "Equalization & Microphone Types" What is the difference between dynamic and condenser microphones?   I n terms of sensitivity, condenser mics are more sensitive compared to dynamic mics. Dynamic mics also require no power, while condenser mics require a battery or phantom. What is directionality?   It is the "pickup pattern" of a microphone in which your microphone can pick up sound from a particular direction. There are three basic types such as omnidirectional, cardioid, and super-cardioid. Omnidirectional can pick up sounds equally from all directions, while cardioid is more sensitive to sounds from the front.  Why would you use a lavalier? A shotgun? A dynamic?   It all depends on the scene's situation. Lavaliers and shotguns are better used when the subject needs their hands free in the shot for things such as hand movements and presentations. Shotgun microphones are also ideal for scenes in which the subject is farther away from you
