Lesson video

Hello, my name is Ms. Powell, and welcome to Computing.

I'm so pleased that you decided to join me here today.

In today's lesson, we're going to be learning how to combine digital images, and we'll be using the select tool and copy and paste to do that.

Let's get started.

Welcome to today's lesson from the unit Photo Editing.

This lesson is called Combining Images.

And by the end of today's lesson, you'll be able to describe how images can be combined.

We'll be using these keywords throughout today's lesson.

Let's take a look at them.

The first word is select.

Select, this means to choose a specific area of a digital image.

The second word is lasso.

Lasso, this means a freehand selection tool.

The third word is magic wand.

Magic wand, this means a selection tool that allows you to choose areas of a similar colour.

Today's lesson is split into three sections.

In the first section, we'll look at exploring different selection tools.

In the second section, we'll you select, copy, and paste to combine images.

And in the third section, we'll evaluate reasons for editing images.

Let's get started in the first section, explore different selection tools.

Editing a photo.

So far you've edited a single image.

You have learnt to: remove things, clone things, change colours, and rotate.

Well done.

You can do all of these amazing things to edit photographs.

You can also edit an image by choosing a selection of the image to copy and paste.

This will change the way a digital image looks.

I've got two images here.

Can you see what has been added in the second image? Pause the video and take a quick look.

What's been changed in these images? You see that there's another wheel added to the back of the vehicle.

This was done by copying one of the other wheels and pasting it.

It looks as if the size has been changed also, it's not the same size as the wheel next to it.

Explore different selection tools.

Let's talk about how you can copy and paste.

Steps to select, copy, and paste part of an image.

Number one, select the area to be copied.

Number two, copy it.

Number three, paste it into the main image.

And number four, adjust the pasted image size and position.

There are four tools you can use to select an area of an image.

Can you see here the toolbar? Four of these tools can help me select an area.

I've got the rectangle selection tool, the lasso selection tool, the ellipse selection tool, and the magic wand selection tool.

To select an area, one, choose the select tool, two, drag the tool around the area with the mouse, or click with the magic wand.

Let's take a little look at the rectangle selection tool.

I can choose this tool from my toolbar here on the left.

I can start at the corner and drag the rectangle selection tool to create a rectangle.

This is very useful if you want to select things that are rectangular.

I have a hint, hold shift while dragging to select a rectangle.

Let's look at the ellipse select tool.

You can also find this here in the toolbar.

If you choose that tool, you can start at the edge of something circular, and you can drag it across to create a circle or an ellipse.

Here, I've dragged my tool across the golf ball and created a circular selection.

I have a hint, hold shift while dragging to select a circle.

Let's look at the lasso selection tool.

I can choose it here from my toolbar.

I can use this tool to draw around an image.

This is useful if your image is not a regular shape.

Let's take a look at magic wand select.

The magic wand tool is used to select areas that have similar colours.

I can choose that here in my toolbar.

I use it to click on the green tree.

It selects a green tree, and it also selects the green grass.

If I don't want the green grass selected, I can change the tolerance.

The tolerance determines how closely the colours have to match.

I have a hint.

Change the tolerance to select more or less of the image.

True or false? There's only one way to select part of a digital image.

Pause the video and have a quick think.

Is this true or false? The answer is false.

You can use the rectangle, lasso, ellipse, and magic wand tools to select parts of a digital image.

I've got a question here for you, I'd like you to give it a try.

Which tool would be best to select the wheel of a car? Do you think it's A rectangle select, B, ellipse select, or C, magic wand.

Pause the video to have a quick think and choose A, B, or C.

The answer is B.

The ellipse select tool would be the best tool to select the wheel of a car.

A wheel of a car is circular, and the ellipse select tool allows us to select circular things quickly and efficiently.

Which tool would be the to select a classroom door? Do you think A, ellipse select, B, lasso select, or C, rectangle select? Pause the video and have a quick think.

Choose A, B, or C.

The answer is C, rectangle select.

This would be the best tool to select a classroom door.

Classroom doors are rectangular, and rectangle select allows us to select rectangular things quickly and efficiently.

Which tool would be best to select A multicoloured star? A, lasso select, B, magic wand, or C, rectangle select.

Pause the video and have a quick think.

Is it A, B, or C? Well done for having a try.

The answer is lasso select.

Lasso select would allow us to draw around the image of a star quickly and efficiently.

Which tool would be best to select the green areas within an image? Do you think A, lasso select, B, magic wand, or C, rectangle select.

Pause the video to have a quick think.

Is the answer A, B, or C? The answer is B, magic wand tool.

That is the best tool to help us select the green areas within an image.

Well done for having a go.

I've got a task here for you, and I'd like you to give it a try.

Explore different selection tools using a selection tool.

You can use a tool like the ellipse tool to drag and select the wheel of this vehicle.

I can drag over it to select it.

Then I can move my cursor up to copy to copy that and then paste.

I now have another wheel.

I can drag that wheel to any place I want on the canvas.

I'll put it right here.

Then I've got the choice to resize the wheel.

I could make it larger or smaller.

Choose one of the images provided and use a selection tool to make changes.

Number one, select, number two, copy, number three, paste, number four, move, number five, resize, number six, press enter to finish.

Pause the video to have a go.

See if you can choose one of the images and use a selection tool to make a change.

You might want to use rectangle select, ellipse select, lasso select, or magic wand.

What do you think? Can you explain the changes that have been made to this image using the selection tools? I've got an image here of a colourful building.

I've edited it to look like this.

Can you explain the changes that have been made to this image and which selection tools I might have used? Pause the video to take a look at the two images.

Try to work out how the changes have been made.

Which selection tool do you think has been used? Let's take a little look at this image together.

This is Alex, and Alex says, I use the rectangle selection tool to add windows and vents to this building.

I've got another task here for you.

Can you explain the changes that have been made to this image using the selection tools? Take a little look at this original image.

Try to work out how it's been edited and changed.

Which selection tools do you think have been used? Pause the video to take a look at the two images.

This is Alex, and Alex says, I use the ellipse selection tool to add more bubbles to make the coffee look frothier.

Well done for having a try.

Well done, you've done so well in the first part of today's lesson, explore different selection tools.

Let's move on to the second section.

You select, copy, and paste to combine images.

Where do you see edited photos? On billboards, packaging, sides of buses, wall art, social media, posters, magazines, and bus stops.

Sometimes, when people make this type of content, they want to combine two images.

You can use a computer to combine images.

If you take a little look at this photograph, what two images do you think have been used to create this edited image? It looks to me as if a bird has been combined with a tiger.

How about here? What two images do you think have been combined to make this edited version? It looks to me as if a picture of a floor has been combined of a picture of a goat eating grass.

And how about here, what two images might have been combined to create this edited version? It looks to me as if a boat has been added to the image of a mobile phone.

Steps to combine images.

Number one, choose the images to combine.

Number two, open them in paint.

net.

Number three, select the area to be copied.

Number four, copy it.

Number five, paste it into the main image.

Number six, adjust the pasted image's size and position.

I need your help here.

I've got some missing words and I'd like you to fill in the blanks.

First, you need to blank two images.

Then open them in paint.

net and blank the area to be copied.

Once you've copied your image, you need to blank it into the main image.

Finally, you can adjust the image's size and position.

Pause the video, see if you can work out what the missing words are.

Well done.

You've done so well having a go.

Let's check the answers.

First, you need to choose two images.

So for example, we might have a bird and a tiger.

Then open them in paint.

net and select the area to be copied.

I might be choosing perhaps my tiger face.

Once you've copied your image, you need to paste it into the main image.

I can take my tiger's face and paste it onto the image of the bird.

Finally, you can adjust the images size and position.

You can combine two separate images in image editing software.

Let's take a little look here at this image.

I'm going to use the ellipse tool to select the image of the basketball.

I'm then going to copy my image and move over to the image of this vehicle.

I can then paste the image of the basketball.

It's a bit big, so I'll resize it, and then I'll move it to where I'd like it to go.

I've decided I'd like it to be a wheel, so I'll move it down here.

Flipping an image.

This image has been flipped to make the moon appear on the left.

In paint.

net, you can flip an image horizontally.

This means I'm flipping it on a horizontal axis, or you could flip an image vertically.

Here, I'm going to flip my image on a vertical axis.

And it makes it look like it's upside down.

Flipping an image.

To flip an open image in paint.

net, click image from the top menu.

Then select flip horizontal or flip vertical.

I can find that here.

So you can choose to flip horizontal, and it looks as if you're flipping it on a horizontal axis.

You can choose flip vertical.

And the icon is showing you you're flipping on a vertical axis.

Don't worry if this goes wrong, you can always use the undo button if you'd like to try again.

Well done, that is super listening.

I've got a task here for you.

I'd like you to use select, copy, and paste to combine images.

Combining two images.

Choose two of the images provided and try copying one to the other.

Think carefully about where your placed image you have added.

In this image, I have copied a basketball, and I've pasted it onto the image of the oranges.

I think that's quite humorous as it looks as if there's basketballs growing from the tree.

Pause the video so you can try the task.

Task B, can you explain how these images have been combined? Which selection tool do you think was used? Pause the video to take a look at the images.

Try to work out how they've been combined.

This is Laura.

And Laura says, I use the ellipse selection tool to select the earth image.

I copied and pasted it onto the photographer image, and then resize it to fit in the lens of the camera.

I've got another task here for you, and I'd like you to give it a go.

Can you explain how these images have been combined? Here on the left, I have the original image, and I've combined it with the image of a bat.

Which selection tool do you think was used? Can you spot something else that has changed? Pause the video to take a little look at the two images.

Try to work out how they've been combined.

This is Laura, and Laura says, first, I tried to rotate the castle so that the moon was on the left, but this didn't work.

I found that you can flip an image sideways by choosing image and flip horizontal.

Then I tried to use the lasso tool to select the back, but it was too hard to draw around.

My friend suggested using the magic wand tool as the bat was one colour.

It worked really well.

Fantastic, you've done really well in the second part of today's lesson, use select, copy, and paste to combine images.

Let's move on to the third section, evaluate reasons for editing images.

There are lots of reasons why people edit images.

Some reasons are positive.

To make someone smile.

Here in the edited version, this little boy has been edited with a party hat.

That's quite humorous.

But some reasons can be negative.

To steal someone's identity.

In these identity cards, the image has been replaced by the picture of someone else.

Can you think of other reasons why people edit images? Pause the video and have a quick think.

You need to think carefully about whether images you see have been edited.

You can, one, look for other photos of that thing and see if they all look the same, two, ask the person who took the photo if they edited it, or three, zoom in on the photo and see if there are any editing mistakes.

Four, think about why the photo was taken.

Photos used in advertisements are more likely to have been edited than someone's personal photos.

Not everyone can tell if images have been edited.

Some countries are worried about how seeing edited pictures can make people feel, especially as not everyone realises the pictures have been changed.

They've decided to make a law that says people must tell you if they have edited an image.

Photos in Norway need to include a badge if they have been edited.

And it looks like this.

This image has been retouched, filtered, or edited to change how the person looks.

True or false, it can be difficult to tell when an image has been edited.

Pause the video and choose true or false.

The answer is true.

Sometimes, photos that look like an original photo may have been edited.

You should also think carefully about whether images you see have been edited.

For example, most images used in advertisements have been edited.

However, likewise, there are lots of edited images on social media.

Which of these checks could you use to decide whether a photo has been edited? Do you think it's A, ask the person who took the photo if they edited it? B, zoom in on the photo and see if there are any editing mistakes.

C, ask someone else for their opinion.

Pause the video and have a quick think.

Do you think it could be A, B, or C? What would help you know if a photo has been edited? In this case, all answers are correct.

All of these are good checks to work out if a photo has been edited.

Is it okay to edit images? This is Lucas.

Lucas wants to send some photos to his cousin who lives in a different country to show him what it's like near where he lives.

He's taken some photos of a park near where he lives, but there is some rubbish in the hedge, some bird poo on the bench, and some graffiti on the pavement.

Lucas tells his friends he is planning on sending the edited photos to his cousin to see what they think.

Here, Lucas has removed the paint.

He's removed the rubbish from the tree, and he's removed the bird poo from the bench.

What do you think Alex and Sofia might think about these changes to Lucas' photograph? Should he send the edited version to his friends or the original? Lucas' friends don't agree.

Alex responds to Lucas, and Alex says, it's not honest to show your cousin the park differently to what it is actually like.

The rubbish and graffiti is part of what the park looks like.

It could also be confusing if your cousin looks for more photos of the park online.

If they find different photos to the one you sent, how will they know which is correct? Sofia says, your cousin won't be able to tell that the photos have been edited.

It's good to try and improve photos by editing them.

Lots of people edit photos to make improvements.

This is just the same.

The litter and graffiti are not always there.

You're just changing the image so that they look like the park did when the bench and the pavements were new.

You're correcting the mistakes someone else made when they didn't keep the park nice and clean.

I've got a task here for you.

I'd like you to evaluate reasons for editing images.

Who do you agree with? Explain your reasons.

Do you agree with Alex? Alex says it's not honest.

Or do you agree with Sofia? It's good to try and improve photos by editing them.

Pause the video and try to complete the task.

Fantastic.

Well done for having a think about that.

This is Lucas' opinion, and Lucas says, I hadn't thought about how my edited images might make me look dishonest.

I decided to send the real images to my cousin, but I also sent the edited ones to show how I would make my area look better if I could.

Well done.

You've done so well in today's lesson, combining images.

Let's summarise.

Different selection tools suit different uses.

Select, copy, and paste can be used to combine images.

Images may be edited for a number of different reasons.

And this brings us to the end of today's lesson.

Well done.
