During the next few lessons we will be exploring…

• Images from light

• Cameras and History

• Spaces for Art

WelcomeSayto

Cheese…

Lets start by exploring images

from light…

Where does light come from and what do we use it for?

Natural light comes from the sun… Having light allowing us to see trees, hills, rivers,

insects, animals, cars, boats. and even each other.

We use light to keep us warm, to generate power through solar panels, to grow plants for food and to have fun at the beach…

Without light it would be very difficult for us to do all these things.

The sun is a ball of energy which sends light to everything it sees, including earth.

Let’s find out by using this torch…How does light travel?

Image: http://www.clker.com/clipart-10401.html http://apod.nasa.gov/apod/ap011015.html

When we use a torch, we notice the light shines in one direction …No matter which way we face the torch, the lightwill always shine in one direction…

This means light can not bend and can only travel in a straight line.

This is the same with the sun and how it shines on the earth…

The sun sends light (or energy) to the earth. Because light travels in a straight line, only half of earth experiences light at one time.

Light and how it travels is an interesting element to see and use.People have used light to do some amazing things

Reflection plays an important part of how light can travelWith enough mirrors you can create a new path for the light to travelReflection happens when light travels and hits a surface like a mirror. When this happens light bounces off the mirror and moves in another direction

Let’s take a look…

Can you see where the light starts in these two images?

You can get really tricky using light and mirrors

Let’s take a look at some other ways people have used light to do some interesting things.

Early scientists found you could create something unique by directing light

through a small hole…

Early camera obscuras were made by first creating a dark room, making sure no light could shine through

They then made one very small hole in the wall looking outside towards a tree

The hole directed light inside and on to the opposite wallThe reason the tree appears upside down is because, as we learnt earlier, light travels in a straight line

The unique part happened when the light shining through the hole projects an upside down image of a tree

The light from the top of the tree travelled downwards into the hole and light from the bottom travelled upwards making the tree appear upside down

Here are some examples of people creating a camera obscura inside their room…

This would later be called a “Camera Obscura”

The image on the wall shows a colourful landscape that is just outside of this room

This image shows a landscape full of tall buildings and roads just outside of this room

These people have managed to capture the sky outside in their room!

More and more people learned of the camera obscura technique and began using it for different reasons…Many artists started using the camera obscura because they could trace over the projected image and create an accurate and realistic drawing or painting.

Over time the camera obscura got smaller and smaller. This meant artists could travel from place to place creating realistic paintings or drawings of different landscapes and people.

Let’s recap on what we have learnt so far…As we have seen, light can help create some amazing things…

Light

• can help keep us warm, help grow plants and provide power through solar panels

• travels in a straight line

• can be directed on to a new path using mirrors and reflection

• can be used to project an image of the outside environment

• is needed for a camera obscura to work. Many artists use this to help create realistic drawings and paintings.

far?What wehave learnt so

In the next lesson we will explore “Cameras and History”.
