A and S are the two common settings found on your camera mode dial. However, on a Canon camera; these two settings are AV and TV.
A(AV) stands for aperture or aperture value. On this setting you can adjust your aperture and the camera will set everything else to the appropriate setting. This used when the subject is still. E.g. landscapes.
S(TV) stands for shutter speed or time value. With this setting, you can adjust your shutter speed. The shutter on you camera is what physically controls the time of an exposure. This is the mechanical sound your camera makes, the shutter opening and closing (If it makes a sound at all.) This setting is used when your subject is moving. E.g. Sports, Animals etc.
There are many complicated settings and confusing buttons on a camera that may take a while for you to learn so that you are able to use the camera to its fullest potential. First of all there’s aperture; this is a reference seen in zoom lenses and are commonly referred to as f-stops. F-stops and have a specific numerical sequence, such as F5.6, F7.1, F8, F11 and so forth. It corresponds to the largest aperture ratio possible at the smallest and largest focal values of the lense.
I find that if I am capturing something and want to separate the subject from the background; it works well to set the aperture at what we call a ‘shallow DOF.’ This is usually about F4.5-F5.6 and is good for portraits. But if I want the whole image to be in focus, I usually go for an aperture of about F7.1 (great DOF). This is good for landscapes.
Today I started my first blog.
The lesson started out, learning about social media and that people can become addicted. Its like a drug, people become obsessed with likes, followers etc. This happens because the brain releases dopamine; a chemical which makes us feel good when we get lots of likes or followers.
Later in the lesson, we learnt how to make our own blog. A place where we can put all of our ideas and what we have learnt.
