This week we got a new learning assignment which we are going to hand in next week, but i decided to start today. It is two assignment about photography. The first assignment was to name all the functions/buttons on the front and back of your camera, explain how you would set the correct ISO, how you would change the aperture and explain how you would change the shutter speed.
Set the correct ISO.
The ISO setting on the camera is to change the exposure settings. It´s really easy to change the ISO to get a smaller and larger aperture. For example, if you put your ISO at 1600, the noise levels get high, so if you pick a lower ISO, like 100, the noise levels get much lower. So i would have taken the photographs with different ISO, so you can see the difference yourself. It`s really easy to change ISO. When i take pictures with my camera, i set the camera on M, which is manual mode and just push the button who is called ISO, and you easily can change the ISO with the control wheel.
Change the aperture.
The values as f/1.4, f/2.5 and f/4.0 is described as a large apertures. They let much light slip through to the film and that`s give you the opportunity to photograph under bad weather conditions. The values like f/11, f/16 and f/22 is described as small apertures. They don`t let much light passing through to the lense. To use the small aperture it requires that it`s much light when you going to take a picture. So i would have changed the aperture by set the camera on manuel mode and then adjust my aperture by press the av+/- and adjust up or down the aperture with the control wheel. Usually i go for large aperture, such as f/4,5. When you want to change the aperture, you can decide wether you want the object to be sharp, or both the object and the background.
Change the shutter speed.
If you for example want to take a picture of a waterfall, and choose to have a long shutter speed, the water becomes like a “velvet effect” the longer shutter speed you have, the clearer will the picture become. Basically, it is three settings in the camera you need to relate to, that is ISO, aperture and shutter. When you are going to take a photograph with long shutter speed, you need to have as low ISO as possible, so there is minimal grain and noise in the image. I would have changed the shutter speed by rotating the control wheel and adjust is like you want it to be.
