The Image Sensors Role In Video

Sensors in cameras, both still and video, come in a variety of sizes. Some popular sizes are Super 35 (Sony NEX-FS100), Full-frame (Canon EOS). While an 18-megapixel point and shoot may have the same number of pixels as an 18-megapixel DSLR, the DSLR has a much bigger sensor. As a result, those 18 million pixels are considerably larger on the DSLR chip. The signal to noise ratio refers to a sensor’s ability to receive more light and deliver more of the actual image, or signal, than noise. The sensor contains millions of light receptors or photosites, which convert the light energy into an electrical charge. Lastly I learned with all the different size sensors, it is important to consider crop factor when looking at cameras. Crop factor refers to your field of view for an image.

Dolly vs Zoom

What is the difference between zooming and dollying? What do dollying and trucking add to the shot? While zoom is created through a static camera change in focal length. A dolly is created by moving the actual camera closer or farther. (Usually on a set of tracks) a dolly can be created using a prime lens, that's because the lens doesn't need to do anything. While a zoom shot only adjusts the camera's focal length a dolly zoom moves the entire camera toward a subject.

The History of Frame Rates Pt. 2

60 hertz = 60 fields per second. It is created in a 60th of a second resulting in a full 30 frames per second. It was chosen over the air broadcasting because flashing the same frame on screen was not an option that was technologically feasible. Engineers were also more concerned about bandwidth, something they were trying to conserve with over the air broadcast. Another reason to conserve bandwidth and avoid flickering each frame would be interlaced. The introduction to color factored in 1948, the FCC (Federal Communication Communion) put a moratorium on new television broadcast licenses as it tried to figure out what to do with the newly available UHF spectrum. TV sets access died off while they tried figuring out what to do.

Horror Lighting Tutorial

They talk about their setups in this video and the main one that caught my attention was the staircase scene they created. They put up two lights the first and 150 watt then they do a light with the projector attachment inside and they put an M size steel gobo that replicates the look of a four panel window thus giving the audience the idea this is coming from somewhere natural its originating from within the scene. The second light they use is the softbox on top of it so its not barefaced and they stick the egg crate on top of it to provide some directionality in the living room we put their third and fourth case of which in this case mul richarchardson they use as much as the same in the  projector attachment to illuminate a back wall.
