The Camera - Aperture & Iris

Image
  - 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 expos...

Progressive vs. Interlaced Scan

Image
  - The Camera - "Progressive vs. Interlaced Scan" What is progressive and interlaced scan?   A progressive scan draws a sequential line that fills a single video frame. It ensures that each frame is filled with a complete image. Interlaced scan, in contrast, displays every other line of an image rather than the whole thing.  Why does it matter?   Interlaced scanning saves bandwidth by cutting down half of a full image. This allowed for older TVs to refresh at a better pace, allowing for smoother transmissions. Interlaced, however, can also cause artifacts which reduce the quality when there is movement on screen compared to progressive scanning. One example of scans being used is during sports broadcasts, in which 720p is used rather than 1080i in order to have better movement in the images. Why should we know the difference?   When figuring out progressive vs. interlaced, it is important to notice the difference in the image between the two. Progressive scanni...

Camera Movements

Crane Shot: a shot at a scene in which the camera moves down into the story/scene from the air. This movement has a feeling of falling into the character's world.  Crane; Wide Vista Shot: a long shot version of the crane shot that gives the feeling of how small the character is, as well how large the obstacle is that he/she has to overcome. Extreme High to Low Shot: when the camera moves from a very high position to a very low position. This gives the character/interest a sense of authority to the viewer, or strong and imposing fear. Handheld Camera Movement: when the camera is handheld and shaky. Imposes a strong feeling of uneasiness or danger.  Quick Pan: immediate change on the emotional direction of the scene. Reveals something dangerous that the character has to overcome, and sends the audience into a totally different emotional direction. Quick Push In: when the camera is pushed quickly towards the character/interest. Imposes a feeling of surprise or shock. Slow Camera ...
