Hello, my name's Ms. Powell and welcome to Computing.
I'm so pleased that you decided to join me today.
In today's lesson, we are going to be learning how you can edit a digital image.
Let's get started.
Welcome to today's lesson from the unit Photo Editing.
This lesson is called Changing Digital Images, and by the end of today's lesson, you will be able to use a range of tools to change a digital image and its composition.
We'll be using these keywords through today's lesson.
Let's take a look at them.
The first word is edit.
Edit: this means to make changes.
The second word is rotate.
Rotate: this means to turn around a central point.
The third word is crop.
Crop: this means to remove parts of an image or a video.
The last word is composition.
Composition: this means how objects are arranged or framed within an image.
This lesson is split into three sections.
In the first section, we'll be learning to recognise that digital images can be altered.
In the second section, we'll be learning to explain how composition of images can be changed.
And in the third section we'll use tools to change a digital image.
Let's get started with the first section: Recognise that digital images can be altered.
Many of the images you see every day have been edited.
Editing an image means changing how it looks.
I've got a photograph here.
This is the original.
What do you see in this photograph? I notice there's a tree and a winding road.
The photograph next to it is edited.
What do you see that's the same and what do you notice that's different? The edited image will look different to the original image in some way.
Things that are different about this photograph, I've noticed that the colours are different.
The original is colour and the edited is black and white.
Did you spot that? Fill in the blanks.
Many of the photos you see every day have been blank.
Editing means making a blank to the original photo.
What do you think the missing words might be? Pause the video to have a try.
Let's check the answers.
Many of the photos you see every day have been edited.
Editing means making a change to the original photo.
Well done.
Editing images.
You can use digital devices to edit digital images.
Digital devices you might know might be tablets, laptops, and mobile phones.
All of these can be used to edit digital images.
Rotating an image.
Sometimes when you look at a digital image on a device, it can be displayed the wrong way up on the screen.
Can you see this photograph here? The parrot is the wrong way up.
It's not displayed correctly.
I can rotate the photograph of the parrot.
This image has been rotated so that it is the right way up.
That's the way this photograph is meant to be seen.
Changing the colour of an image.
In this example, the colour of the image has been changed.
A teacher took a photo of a child in her class as part of a history project.
They changed the image to black and white to make it look like it had been taken in the past.
Cropping an image.
In this example, the image has been cropped.
A teacher took a photo of one of the children for the school website.
They didn't want to include the goalkeeper from the other school, so they cropped him out of the image.
Cropping can be useful in this way.
I need your help.
Can you help answer this question? Removing a section from an image is called.
A :rotating, B: cropping, or C: duplicating? Pause the video and choose the answer A, B or C.
Well done for having a try.
Did you get B: cropping? Cropping allows you to remove parts of an image.
I've got a task here for you.
I'd like you to give it a try.
How has this image been edited? Pause the video so that you can look at the two images, the original and the edited.
See if you can work out how it's been changed.
This could be by cropping, rotating or by changing colour.
What do you think? Pause the video and have a try.
Fantastic.
I'd like you to try again.
I've got two more images and I'd like you to have a think, how has this image been edited? Take a look at the original and the edited image.
They could have been cropped, rotated or the colour could have been changed.
Pause the video to have a try.
Well done.
You're doing really well.
I've got another task here for you.
I'd like you to have a look at this image and have a think, how has it been edited? You've got an original and an edited version.
Pause the video to have a think.
Let's have a little look at how the images have been edited.
So for the first pair of images, the tree and the winding road, the original image has been edited with a filter to change the colour.
It looks as if the colour has changed to black and white.
How about the second two images? The original image has been turned or rotated so that it is the right way up.
What about the last pair of images? The original image has been cut or cropped to remove the background and focus on the lion's face.
Well done, you've done really well in the first section: Recognising that digital images can be altered.
Now let's move on to the second section and explain how composition of images can be changed.
Taking a photo.
When you take a photo, you can decide how the objects in the photo are arranged before you take your picture.
Here's a photographer and he's taking a picture of some fruit on the table.
It's photo one.
The apple is in the foreground and the banana is in the background.
The pear is next to the apple.
Perhaps he might like to take the photograph differently.
And here's photo two.
The photographer's moved the banana next to the apple on the right and now the pear is in the background.
So when you're taking a photo, you can decide how the objects in the photograph are arranged.
Before you take your picture, you might want to move some objects around.
You can also decide which objects appear within the frame of the photo.
Here's the photographer and the photographer's looking at a lighthouse, there's a sheep in the foreground.
The photographer might decide to take the photograph like this.
Here the photographer has focused on the lighthouse.
And here is photo two.
The photographer has decided only to shoot the lighthouse and has decided not to include the sheep.
Composition.
When you think about how the objects are arranged or how the photo is framed, you're thinking about the composition of the image.
Composition is how the objects are arranged or framed within an image.
Photo editing.
When you edit a digital image, you can make changes to the original composition of the image.
Digital images are often edited to make changes to the original image for a variety of purposes.
Cropping.
You can change the composition of an image by cropping it.
To improve the focus on the lion's face, you can remove the rest of the image.
Here, I've cropped my photograph and I've removed the background.
I've changed the composition of the image.
I think this gives more focus to the lion in this image.
Sometimes when you see a photo for the first time, you may not know that it has been edited.
If you saw this photograph of the lion, would you know that I had cropped it? Cropping to centre.
The football's not in the centre of the image.
You could crop the left side of the image.
Cropping to avoid distraction.
Sometimes you can crop a photo to cut out something that is distracting.
Can you see in this photograph of the teddy bear, I've decided to crop out the open door? I think this gives more focus to the teddy bear.
Cropping to change the main topic of the photo.
Here, we've got two photographs.
On the left we've got two figures walking through the woods, and here on the right, the image has been cropped.
Does cropping the image change how you feel about it? What do you think? Pause the video and have a think.
What are the things that you think about when looking at these images? In this photograph, I think a little bit about a journey exploring an unknown location.
To me, those tall trees look a little bit foreboding.
However, when the photograph has been cropped, I feel that an adult and a child are out for an everyday walk in the woods.
The cropped image looks a lot less spooky than the uncropped image.
I've got a task here for you.
Folding your image: unplugged activity.
You are going to explore how the topic of a photo can be changed by folding.
Number one, get a printed photo of your choice.
Some examples have been provided as downloadable files.
Number two, look at the image carefully and decide which part you want to keep.
Number three, fold the image to remove the parts you want to remove.
I've got my image here, it's of three hot air balloons and a lighthouse.
I've decided to fold away the lighthouse and I've also decided to fold the sea.
This leaves the three hot air balloons remaining.
Number four, explain why you chose to remove those parts and what effect this has on the image.
Pause the video to try the task.
Well done for trying the task.
Here are the three hot air balloons, and this is Jun's answer.
"I folded the image to focus on the hot air balloons.
They're colourful and I'd love to travel in one of them in the future.
I removed the lighthouse, the sea, and some of the sky background.
It makes me think that the balloons are floating higher in the sky because you can't see the land." Well done for completing the second section: Explaining how composition of images can be changed.
We're now going to move on to the third section: Use tools to change a digital image.
Editing images.
You're going to edit photos using a free programme called paint.
net.
First, you're going to open an image and rotate it.
Do you remember? Rotate means to turn the image.
Let's have a little look at paint.
net image editor.
Look at paint.
net and see if there are any tools that you recognise.
Here we've got the canvas.
The canvas is the place for your image to go.
We've also got an image list.
This is so you can move between your images.
Here on the left is a tools panel with lots of helpful tools that you can use to edit your image.
Can you guess what any others might do? Pause the video to have a look and guess what the other functions might be of paint.
net.
Let's first open an image We need to go to File, then scroll down to Open.
This allows us to open an image.
Next, let's rotate an image.
Number one, select Image.
Number two, select Rotate.
Here you can choose to rotate 90 degrees clockwise, 90 degrees counterclockwise, or 180 degrees.
Let's try and crop an image.
Go to the tools on the left and then select the area to crop.
You're going to have to drag over your image to select the area.
Then look above and go to Crop to selection.
Let's look at using the Undo and Save tools.
If you go to Edit, you can press Undo or Redo.
This lets you go back if you've made a mistake or go forwards and repeat what you've just done.
Let's look at the save tools.
You can go to File.
There are two tools, Save and Save As.
Save allows you to save over the existing image.
What this means is that the new image will replace the original image.
Save As lets you save it as a new image.
This means that you'll still keep your original and the one that you've edited will be a new image.
Well done.
That's super listening.
Let's have a little think.
Which of these icons would you use to crop a digital image? I've got three icons here.
A, B, or C.
What do you think? Pause the video and have a try.
The answer is B.
B is the icon you'd use to crop a digital.
I'd like you to try another one.
Which of these icons would you use to rotate a digital image? I've got three icons, A, B, or C.
Which one do you think would help you rotate? Pause the video and have a guess.
The answer is A.
Well done for having a try.
Which of these icons would you use to save a digital image? What do you think? Is that A, B, or C? Pause the video and take a look at the icons.
Which one would help you save? The answer is C.
This icon would help you save your digital image.
Fantastic! I'd like you to try this one.
Which of these icons would you use to undo a mistake? What do you think? Is it A, B, or C? It's C.
This one would help you undo a mistake and go back one step.
I've got a task here for you.
I'd like you to use tools to change a digital image.
Number one, choose a photo and open it in paint.
net.
Number two, rotate the image so that it is the right way up.
Number three, use the crop tool to remove parts of the image.
You can choose what you'd like to remove.
Number four, explain why you chose to crop your image in this way.
Number five, how did the edits change how you feel about the image? Pause the video so that you can complete the task.
Fantastic, you've done really, really well in today's lesson: Changing Digital Images.
Let's summarise.
Photo editing software can be used to edit a digital image.
The composition of a digital image can be changed.
Tools such as crop and rotate can be used to improve an image.
Well done in today's lesson.
I look forward to seeing you in the next lesson.
