The second lesson task this week, I were to watch the video: Introduction to Photography: The Camera by Ben Long (1h 52m) and answer the following questions:
1. Name all the functions / buttons on the front of your camera
2. Name all the functions / buttons on the back of your camera
3. Explain how you would set the correct ISO
4. Explain how you would change the aperture
5. Explain how you would change the shutter speed
I have a Canon 400D EOS and I named the functions/buttons in Illustrator by using picture of my camera.
1.Name all the functions / buttons on the front of your camera
2. Name all the functions / buttons on the back of your camera
3. Explain how you would set the correct ISO
The faster the camera ISO, the faster the shutter speed. When the ISO is higher, it is more sensitive to light and will take the shot faster. But to high ISO is the reason for grainy images. It all depends on the light source I have, to set the correct ISO. If it is day/night, if I am using flash or other light-sources.
Ideally, if I am outdoor and have light from the sun, ISO number can be low, at 100. If it is a rainy/overcast day the ISO number can be 400. If I am inside in the dark without flash or at night the ISO can be 800.
4. Explain how you would change the aperture
The aperture is set inside the lens. The more widened out, or the larger the hole in the lens is, the more light will enter through the lens and hit the image sensor. The smaller the hole, less light will enter.
The «f»-number on the camera indicates how large or small the hole is. Higher «f» -number = smaller hole. Lower «f»-number = larger hole.
Higher aperture is better when I want everything in the shot to be in focus, for example a landscape shot. Low aperture is better for low-light scenarios.
5. Explain how you would change the shutter speed
Shutter speed refers to the amount of time that the cameras shutter opens. The longer the shutter speed, the more light is let in to the camera. The shorter the shutter speed, the less light is let in to the camera.
If I want to freeze the motion of a moving object, I need to use a shutter speed faster than the moving object. It depends on the direction from the camera position and the object and the distance from camera to the object, with what shutter speed is required.
To change the shutter speed, I hold down the Shutter release button or turn the Main dial button on the camera, to set the correct shutter speed.
