# Scene composition

Use the tool below to compose two scenes. Experiment with different camera settings to see what effects you can create.
You can switch between two scenes using the dropdown menu above the image and choose the camera setting with the sliders below the image.

## Quiz

Once you have experimented with the camera tool, try to answer the questions below.
Increasing the focal length has the effect of
.

Notice that in both scenes, the character in the foreground remains the same height. To achieve this, as we increase the focal length we have to move the camera
the scene.

As the focal length increases, the background appears to move
the camera.

If we keep the focus on the character in the foreground, as the focal length increases, the background appears
blurred.

## Discussion questions

How does using a long lens (such as a 200, start text, m, m, end text lens) affect the feeling of a scene?
When would you want to use a wide angle lens (such as a 28, start text, m, m, end text lens)?
If you wanted a viewer to focus on a particular element in a scene, what sort of lens and f-stop might you use?
When might you want more of the background to be in focus?

• I can understand what is f-stop and focal length.What is focus(m) then ?Please clear my confusion.
• Focus is acheved when all the colors of our subject (almost) "hit" the sensor of our camera (photograph or film). With the use of our lense [the distance of it from our plate (sensor)] we are managing the light rays of our subject of interest to convergence on our plate, that`s when we have in focus objects.
• how is joy the same size even when switching lens. you should be able to see different amounts. like the background
• it could be because if you change something on a real camera. The numbers just keep getting bigger and bigger and bigger
• it takes forever
• understanding how to use a camera is hard.
