Tested along the way how well the camera knowledge has sunk in.
23rd – Aperture

Fridays – Showreel, Vimeo page or Website
Interlaced – T.V., live, documentary
Progressive – Filmic – Drop a field (25fps)
Upper field – DVCAM
Lower field – (small cam)
(De-Interlaced) – If the fields are the wrong way round, the video will be flickery.
LED – light emitting diode (10 years lifespan) – SOLID
LCD – Liquid crystal display (2-3 years lifespan) – LIQUID
PLASMA – GAS – Hardly ever used
C.R.T – Hardly ever used
P.A.L – Phase Alternating Line – Britain – TV Standard – 50Hz
N.T.S.C – North America – TV Standard – 60 Hz
S.E.C.A.M. – France – TV Standard – 50 Hz

Aperture, ISO, Shutter speed
Aperture – F setting – F Stop
- Blurring the background of an image
(Pupil) like an eye is like the iris (aperture) on a camera
Diaphragm (affects the size of the aperture)
F – stop – Small aperture – Large number – f/22
Large aperture – Small number -f / 1.4
Inside – Open up aperture
If you are outside – Close the aperture
F8 and be there – If you aren’t sure of the lighting then use f8.
f/32 – D.O.F. – Depth of field – Focus near and far with a smaller aperture for example filming a pebble on a beach would be a high f setting to get the best focus. If you want it to blur, you change the aperture accordingly.
f/1.4 – Focus near not far or vice versa not both.
There can be different lenses:
Fixed (Prime) 1 x focal length – f stop remains the same
Zoom lens – Tighter and wider – Variable apertures
If you have a 18mm – 200mm zoom lens (zoom out) f/3.5 zoomed in is f/5.6
Some zoom lenses have no change in aperture like a fixed lens but most will.
I.S.O. or A.S.A. – Sensitivity of what is recorded – Sensitivity of film to light
(International Standards Organisation)
Lower number – lower sensitivity
High ISO is used in darker situations/locations e.g. to freeze each frame – sharpness
The recording becomes noisy e.g. recording sport. A darker situation so therefore you need to set a higher ISO but then you will have a noisier recording.
ISO 100 was the image on the left and ISO 3200 was the image on the right.
Below is ISO 200 – ISO 3200
100-400 ASA is a small aperture so you could start off with an aperture of f/2.4 – f/8
Indoor Sport – For indoor sport you would have a low ISO because you don’t want any grain. You would not use legs because it would constantly be moving. You would have a large aperture because it is filmed inside. – Limited light.
Concert – For concerts you would have a higher ISO because it would most likely be filmed indoors with no grain. You would use camera legs to get a still shot and have a large aperture because it would be fairly dark.
Museum of Art – This would be filmed with a high ISO with high grain and you would definitely use camera legs to get some still shots and have a high aperture.
Chinese New Year – This would be filmed with a low ISO because it would be filmed outside and you would have low grain. It would most likely be filmed on a stills camera and with legs with a low aperture.
SLR – Single lens reflex – Deflecting the light into the view finder.
Shut – Light sensor – Shut – Exposed
Length of time of exposure
Slower or faster
Fast shutter speed – Filming birds (1/250th of a second)
ISO needs to increase to 800 because of the sensitivity because we increased the shutter speed.
Iris – Aperture f/2.4
Filming a car crash at night in front of the tower block – High shutter speed at about 1/400th and therefore the ISO would need to be increased to 800 because it would be filmed in the dark and the iris would have an aperture of f/2.4 with lots of lighting.
Aperture priority mode – I set the aperture and the camera will automatically set the shutter. ISO set.
For indoor sport you would set them to manual and control the aperture and shutter yourself.
