Today we had a photography induction with Dave. We learnt about digital SLR’s, in particular a Canon EOS 600D which, I have to say, isn’t bad equipment although it has been discontinued by the manufacturer. But that’s not to say that we are behind, but that Canon are forever bringing out new material and progressing.
I’ve always had an interest in photography, I even studied it for two years previous to my degree so there wasn’t a lot we learnt that I didn’t already know. However, for those who hadn’t studied photography before or had ever used a camera, I imagine it was more than helpful, if not a little mind boggling with all the numbers thrown at us.
We learnt about a variety of camera tricks and tips. Such as MF (manual focus), AF (auto focus), the different lens types, stabilisation, how to format the camera before using it, changing the quality, etc. It was a lot of information for a sixty minute tutorial but it was helpful nonetheless.
We learnt about the three pillars of photography:
Aperture; ‘the bigger the hole, the more light‘ quoted from Dave. The aperture affects a few things, for example the depth of field. If you let little light into your shot, you are going to narrow the depth as you won’t be able to see past the object you want to focus on. The different aperture numbers are known as ‘F stops’ and either increasing or decreasing this will affect how much light you allow into the camera and, in turn, will make your image darker, or lighter.
ISO: ISO is the sensitivity to light. The higher the ISO the more sensitive it is. This is measured according to international standards so ISO100 on one camera will be the same as the ISO100 on another.
Shutter speed: A camera shutter is a curtain in front of the camera sensor that stays closed until the camera fires. When the camera fires, the shutter opens and fully exposes the camera sensor to the light that passes through the lens aperture. After the sensor is done collecting the light, the shutter closes immediately, stopping the light from hitting the sensor. It is responsible for creating dramatic effects by either freezing action or blurring motion, this is known as the shutter speed. Shutter speed, or exposure time, stands for the length of time the shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely and create a still image. If the shutter speed is slow, it will create an effect called ‘motion blur’ where moving objects appear blurred along the direction of the motion. This is a good technique for catching flowing water and it often used in car advertisements.
With all of this new information in mind, these are the images I took:
