PPT-Camera ISO, Aperture, & Lens

ISO Generally defined ISO is the cameras sensitivity to light If the camera has a low ISO the camera will be less sensitive to the light coming in If the camera has a high ISO it will be extremely sensitive to light ISO settings are as follows 100 200 400 800 and 1600. 5 Beermat Board 2S FIN000035 ISO 536 ISO 534 ISO 287 ISO 2470 ISO 87912 ISO 82541 TAPPI 569 380 390 420 430 500 575 600 640 660 700 880 900 970 1000 1150 1350 1400 1500 1550 1650 70 70 70 70 70 70 70 70 70 70 Understanding the relationship between three critically important parameters: the ISO speed, aperture (or f-stop number), and shutter speed. .

Depth of field is the range of the scene that stays sharp and focused. As we create small apertures the depth of field increases. As we set large apertures the depth of field decreases. . 2.

Aperture. The aperture is the opening at the rear of the lens that determines how much light travels through the lens and falls on the image sensor. . The size of the aperture’s opening is measured in f-stops. SD Cameras run on an SD card similar to what is inside a USB . flashdrive. . Each video clip is a file. These cameras are very durable but the quality suffers. - This is what we use in BRI. HD Cameras run on a . The camera. All cameras are basically the same. A box with a piece of “film” in one end. A hole in the other end. The hole is there so that light can enter the box, strike the light-sensitive surface of the film and make a picture. 1. Types of Cameras. Still Cameras. Fixed Lens Cameras.
