General Quiz 2

Here is the correct answer:

Remember this:

Aperture is an opening which lets light into the camera. The wider the opening the more light gets into the camera. So aperture controls amount of light which gets into the camera.
It also controls Depth of Field, or how much of the image will be in focus.

Remember this:

Remember this:

You can do better next time. Just remember what ISO measures the sensitivity of the sensor or film to light.

Remember this: The higher ISO, the more sensitive to light it is and the lower ISO the less sensitive to light it is. In this case ISO 200 is lower ISO then 1600, this is why it is less sensitive to light.

You will also get more noise at higher ISO. In this case ISO 1600 will give you more noise.

Remember: Exposure is the amount of light which gets into the camera and is projected onto recording media (sensor).

Remember: Depth of Field is controlled by Aperture Opening. The smaller the Aperture Opening (which is the higher F-number), the more Depth of Field you get.

This is how it goes:

You can change your ISO to 100 or your Aperture to f8 or your Shutter Speed to 1/125 to get more light into the camera, which will fix underexposure problem. The answer is any of the above, but not all at the same time. It you make all those changes at the same time, you will add 3 stops of light instead on 1. This will make your image overexposed.

Remember:

Depth of Field is influenced by Aperture, Focal Length of the Lens and Distance to the Subject.

I would rather use aperture priority mode for a portrait, because I want to control DoF, which is influenced by aperture. Aperture priority mode lets me to control the aperture and camera will adjust the shutter speed accordingly. While you are using aperture priority mode for portrait, you should still pay attention to your shutter speed to make sure that it is not to slow.

Soft even light was used in this image. As you can see there are no shadows on the models face. Hard light would create shadows.

Remember:

Photos taken in the share tends to be cool (bluish). Shade WB Mode will add more warm yellow tones to the image to compensate for blue.

Repetitive Patterns and Vertical Lines on the background make this image powerful.

This is how it goes:

By looking at the water we can immediately tell that slow shutter speed was used for this image. This is why the answer is 15s F5.6 ISO 100.

RAW files:

PROS:
1. No data is lost
2. Allows you to correct mistakes made at the time of exposure
3. You have a lot of flexibility with manipulating the image in post
4. Adjustment made in postprocessing are non-destructive

CONS:
1. Very large files compare to jpeg
2. Images can’t be used immediately for printing, e-mailing, etc.
3. Special program is needed to edit images and turn them to jpegs
4. Require time and effort to “develop”

It is false. F/16 actually lets less light then F/11, since F/11 has a bigger aperture opening then F/16. Remember the bigger the F-number, the smaller the opening and the smaller the F-number the bigger the opening.

It is just a rule of thumb, but you should know it. It also depends on the length of the lens and if it has VR. Also it depends on photographer. Some people can hold the camera without camera shake at slower shutter speed then other. Also consider what you had to drink last night, lol.
