60 fps
2. Parameters for controlling exposition
Every step in photography means double or half light.
2. Parameters for controlling exposition2.1 Shutter Speed
Amount of time every frame is exposed for.
It affects: a) The amount of light that enters the camera b) Motion blur
It’s expressed in fractions of second or seconds. Ex: 1”; 1/50th seconds
The higher the number of the fraction, the darker the image
2. Parameters for controlling exposition2.1 Shutter Speed
RULE: Double the frame rate

2. Parameters for controlling exposition2.1 Shutter Speed
Why does my camera have 1/50th? Because I have it in thirds or half stop in-crements
Why does the image flicker when I’m in the correct speed for my frame rate? Flickering of the fluorescents 1/60th
2. Parameters for controlling exposition2.1 Shutter Speed
2. Parameters for controlling exposition2.2 Aperture (f stop)
Wide the lens opens to let light in
It affects: a) The amount of light that enters the camera b) Depth of field
The higher the number, the darker the imageThe lower the number, the brighter the image
Watch out when making zoom-in or out with a Zoom lens!!! Cau-se they normally have a Variable Aperture, rather than fixed.

2. Parameters for controlling exposition2.2 Aperture (f stop)
2. Parameters for controlling exposition2.2 Aperture (f stop)
Depth of field depends on: a) Aperture b) Distance from camera to number of focus c) Focal distance in the lens
You can use it shallow to create a centre of attention in image. You can combine it with PULL FOCUS
Normally, f full stops in the medium of the aperture range of a lens, give be-tter definition. The higher and the lower numbers of aperture for a lens start to lose definition in the borders.

2. Parameters for controlling exposition2.2 Aperture (f stop)
Reciprocity law:Reciprocity is the law of the relationship between shutter and aperture. It stipu-lates that one stop increases in aperture is equivalent to the shutter duration doubling. Both increase light by one stop.

2. Parameters for controlling exposition2.3 ISO
Makes the sensor sensitive to light
It affects: a) The amount of light that enters the camera b) Digital noise
The higher the number, the brighter the imageThe lower the number, the darker the image

4. Measuring light4.1 Two basic methods
Incident Light
Reflected light
4. Measuring light4.2 Light zones
All light meters are designed to measure light for an average reflectance or a neutral gray. And that coincides with Zone V
4. Measuring light4.2 Light zones
4. Measuring light4.2 Light zones
4. Measuring light4.3 Reflected MeasurementWill give you always exposition for ZONE V based on the light the subject reflects. So you always have to interpret the info.It will give you, for the same light, different exposition values for a White cat (which reflects a lot of light) and a Black cat (which reflects less light). It will take both cats to the same middle gray. So you should know what Zone is everything you measure.An average caucasic person is Zone VI and White with texture is zone VII-VIII. It’s handy to go for the white surface in your image and open the aperture to fit the zone VII-VIII, so always, for white, open two or three steps from what the light meter of the camera tells you to (which would be middle gray).
