Memory Check

What is ISO and what does it effect?

• ISO stands for International Standards Organisation and it affects how sensitive the camera is to light. The drawback to using a high ISO is that the pixels become grainy and detail is often lost in the photograph taken.

When would we use the ‘P’ control setting on the camera mode dial?

• The 'P', or Program, setting on the camera is something akin to semi-automatic. The camera would handle most of the work, but you can make adjustments to the ISO and White Balance when you need to.

• We would use the Program setting on the camera when more flexibility is required. It is also helpful when working on composition, as it means that you don't need to worry about the aperture or exposure when getting shots.

Name two important considerations when attaching the tripod base plate to the bottom of camera?

• Make sure that it is fastened tightly to lessen the chances of it coming loose.

• Ensuring that the and ensure that it is put on the right way around, with the arrows pointing towards the lens. 

Name three important considerations when using a red-head lighting kit.

• Make sure not to touch the red-head light and the surrounding barn doors that are there as the protection. 

• Leave the red-head light to cool down for 10-15 minutes after use. If this is not done, the filament in the light bulb is prone to breaking.

• Health and safety regarding the power cables of the light should be taken into consideration.

When focusing the camera, what do we place on the object/subject to ensure it is the center of focus?

• The small green rectangle that appears is where the subject of the photograph needs to be, so that it is the center of focus. In order not to break the rule of thirds, once the shutter button is held halfway down for the focus, the camera should be moved to get the right composition for the shot.

Name two techniques we can use to adjust the brightness and contrast of a photograph?

• To adjust the brightness and contrast of a photograph, you can use the 'levels' and 'curves' tool in Photoshop. When using the camera, we could adjust the brightness and through control of the ISO, shutter speed and aperture.
