Camera Techniques

Over the past few weeks, we have been practising with SLR Cameras which feature a number of techniques, such as : Aperture, shutter speed and ISO. All of these techniques can judge a photo instantly depending on what the settings are set to.

Shutter Speed :

Shutter speed controls the light and motion detected in a photograph. The camera auto focuses on the object ( can be done manually as well) and takes the photo. Shutter speed is read as a fraction. Ranging from:

1/4

1/30

1/260

1/1000

The quicker the speed, the better the freeze lotion will be. This is so you're can capture moving objects without blur. But it lets less light in and gives it a darker image depending on what the setting is. Vice versa for a speed. More light in the photo but it has a blur lotion. 

Aperture:

With aperture, you can stabilise the depth of field in the photo. For example, if I wanted to just capture a photo of the object in front of me while everything else is blurred, I would give it a short depth of field. So that would be an F stop below 4. If I wanted the whole background, I would have a higher F stop. You can use many camera lens for aperture. Preferably people would use a wife angle camera lens to capture the whole background. 

Iso:

ISO is what sensitivity your camera is. If you were to give a low ISO setting, it would be less sensitive towards the light and it would have more grain. People use higher ISO to gain a faster shutter speed and is typically used in dark areas and backgrounds. 100 ISO is the normal setting as this gives a crispier shot and it has less noise.

Here is an example of all the settings in their work.
