1. What is white balancing, why do you do it, and what does it accomplish?
- We can instruct a camera to use a particular colour temperature to fulfill our need. This adjustment that makes sure the white colour we view directly will also appear white in the image is referred to as white balance.

2.  Name 3 of each and explain the difference between Camera and Director's Instructions.
- Camera- Tilt, Zoom, Pan
-Director's- Cut, Standby, Action
The difference between the above is that Camera instructions are done electronically whilst Director's Instructions are carried out manually in the form of instructions given on set to the camera crew and the cast.

3. What is AGC and what does it do? 
- this is an adaptive system found in many electronic devices. The average signal level is fed back to adjust gain to an appropriate level for a range of input signal levels.

4. If you do not want 16:9, what is the other option for shooting and what does it mean?
- the other option for shooting is 4:3 which stands for a standard screen.

5. When you open the iris on a camera, what does it do to the picture?
- The iris is an adjustable aperture used to control the amount of light coming through the lens. The more the iris is opened, the more light it lets in and the brighter the scene will be.

6. Apart from white balance, what else should you check before each scene?
- It is always advisable that a camera man check his audio before before shooting and also, camera settings in terms of resolution etc. This will inevitably lead to the quality of the material in the end.
