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 evaluate a digital image so that we can improve it.

Let's get started.

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

Let's take a look at them.

The first word is improve.

Improve, this means make something better.

The next word is review.

Review, this means to look at something and give your opinion.

Lesson outline, "Evaluating digital images." This lesson is split into two sections.

In the first section, we'll review an image and suggest improvements.

And in the second section, we'll improve an image using editing tools.

Let's get started with the first section, "Review an image and suggest improvements." "Review an image and suggest improvements." You have created an image that uses parts of other images.

Here's Laura's image, and she's created this using different photographs.

What do you spot here? It looks as if Laura's used a chipmunk head and a kingfisher body.

She's copy and pasted the chipmunk onto the kingfisher.

Laura has also included lots and lots of mushrooms. If you look closely, some of the mushrooms are the same.

I think she's cloned them.

You can improve your publication by adding the title.

This helps people to know what your publication is all about.

Here Laura has added her title, "Forest Friends." This helps people know what the publication is all about.

Let's look at how you can add your title in software like Paint.

NET.

If we go down to the toolbar, we can choose the T icon.

This allows us to type our text.

Here I've typed, "My title." If I scroll above, I can choose a number.

This lets me decide how big or how little I want my title to be.

I'll choose 108.

Next to that, I can choose the font.

The font changes the style of the letters of the title.

You can move your title around, I can drag it here down to the bottom.

Add your title, add text, change the size, change the font, change the colour, position your text, and save your finished image.

You might need to change the colour of your text if it doesn't shop well on your image.

I've typed my title "Forest Friends" here on my publication but you can't see it very well.

If I use my magnifying glass, you can just about see the black text.

Black isn't a very good colour for this title.

I think something with greater contrast, like white or yellow or red, might show up better.

If you are having this difficulty, then you can change the colour of your title so that it shows up better on the background.

Let's see how I can change the colour of my title.

Use the colour wheel to change the colour of the text.

This is the colour wheel.

Once you've added text, you can choose a colour by dragging the selection point to a colour of your choice.

Or choose a colour here.

So there are two places I can choose a colour.

I can use my mouse and click on a colour in the colour wheel in the circle, or I can click on a colour below in the colour palette.

If you can't see the colour wheel, click here.

Can you see there's a very small colour wheel icon up in the corner? I need your help.

True or false? You need to think carefully about the colour of the text in your image.

What do you think? Pause the video and choose true or false.

The answer is true, and why is that? If you have a light background, darker text will stand out better.

If you have a dark background, lighter text will stand out better.

Well done, that was a really good try.

I've got another question here for you I'd like you to answer.

You change colours using the colour wheel.

If it isn't showing on your screen, where can you find it in Paint.

NET? Is it A, in the menu on the left-hand side? Is it B, at the top right of the page? Is it C, in one of the dropdown menus? Pause the video and have a think.

Where can you find the colour wheel if it isn't showing on your screen? That's right, it's B.

At the top right of the page there's a small icon and it looks like a small colour wheel.

Review an image and suggest improvements.

You're going to review your work and think about two things you've done well and one thing that you would like to improve.

Two stars and one wish.

So the two stars are two good things that went well, and the one wish is something you wish could be better.

Better take a step back from your work.

Looking at it again can help you find ways to improve it.

Here's my publication "Magibeasts." I'm going to take a step back and have a little look and think about how I can improve it.

Perhaps I could try and soften this join.

I think this part doesn't look very natural.

I could blur this background more.

I've blurred parts of it, but you can still see it if you look closely.

Perhaps I could improve it by blurring it a bit more.

I could stop the text overlapping here.

The T is going onto the giraffe's face, it makes it a little bit harder to read.

Perhaps I could change my font size.

Laura looked carefully at her work to think about two things she'd done well and one thing she would like to improve.

So here's Laura and this is Laura's publication, "Forest Friends." Laura's thinking of her two stars and a wish.

The first star, "Although I found it hard to draw around the bird and chipmunk using the lasso tool, I kept trying and it looked okay in the end." Something else that went well for Laura.

"I was really pleased that the cloning of the mushrooms worked so well." Let's see what are Laura's wishes, what she thinks she could have done better.

"I would like to improve the join between the chipmunk's head and the bird's body." I wonder how Laura could improve that join.

It doesn't look very natural, it looks as if it's been cut and pasted.

I have a task here for you, I'd like you to give it a try.

It's your turn now.

I'd like you to add text to your publication to help tell people what your publication is about.

"Forest Friends," this text looks really great here in white on the dark background.

Pause the video so that you can add your text.

Fantastic, well done for adding your text.

Number two, review your image.

Think about two things you've done well and one thing you'd like to improve.

Explain your reasons.

This can be two stars and one wish.

Pause the video so that you can review your image.

Well done, you've done so well in the first part of today's lesson, "Review an image and suggest improvements." Let's move on to the second section, "Improve an image using editing tools." When you are editing images, the first image you create might not be perfect.

Often you'll need to make a number of changes along the way until you're happy with the finished result.

Here's Laura, and Laura's got an image.

Image 1, she's not very happy with how it looks.

She's changed it again to image 2, and here she's changed it again to image 3.

It was the third attempt where Laura felt happy that her picture had the best end result.

So don't give up, keep trying.

Change your images in different ways.

You can always save different versions and look back to see how they've changed and what's different.

Improve an image using editing tools.

Think about the skills you've learned so far.

You've learned how to crop, so you can take away parts of an image.

Rotate, you can twist an image around to view it better.

Undo, you can go back a step.

You can use the effects, so you can change the appearance such as the colours of an image.

You can add text to an image with the T icon.

You can copy and paste, so you can take part of an image and stick it onto a different part of an image.

You can use the select tool, you've got the rectangular select, ellipse select, lasso select and the magic wand.

You can clone or retouch, and you can use Save or Save As.

You've learned so many skills in this unit, well done.

I need your help.

I'm not so sure.

Which order do you think these images were created in? Can you explain which tools have been used? Pause the video and take a quick look at the images A, B, and C.

Try to work out which order they were created in and what tools might have been used to change the image.

Pause the video to have a go.

Well done for having a try.

B is the original image.

It was the photograph taken on the camera.

C is the first edit.

This image has been made smaller and the crop tool has most likely been used.

Edit 2, this is the final edit to this picture.

The effects have been used and the colour has been changed to black and white.

Well done, you're doing really well.

I need your help again.

Look at the original image, A, and the edited image, B.

What tool has been used? Pause the video to take a look at the images.

That's right, the rotate tool has been used to turn the image around.

Improve an image using editing tools.

Think about what you wanted to improve about your image.

Here's Laura, and Laura says, "I would like to improve the join between the chipmunk's head and the bird's body." Think about the skills you may need to use.

What kind of skills here do you think would improve the join between the bird's head and the bird's body? I think Laura could maybe use a clone or retouch tool to improve the join.

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

Explain what you'd like to improve on your image and how you'll edit your work to improve it.

Do you remember the "Magibeasts" image? I had also wanted to improve the join on the giraffe's face and also I felt that the text could have been a little bit smaller to stop it overlaying.

Pause the video and take a look at your image and try to work out how you'd like to improve your image.

This is Laura, and Laura says, "I would like to improve the join between the chipmunk's head and the bird's body.

I think I can use the clone tool for this.

If I clone the fur of the chipmunk and blend it in with the bird, it will hopefully look better." Well done, super listening.

I've got another task here for you, Task B, improve an image using editing tools.

I'd like you to give it a try.

Number two, make improvements to your image based on your review.

So you're going to think of your wish, what could have been better, and you're going to make improvements.

Number three, explain how you made your improvements.

Well done, I bet your publication's going to look better and better each time you try.

Here's Laura, and Laura said, "I used the clone tool to soften the edge where the chipmunk's head meets the bird.

I tried to give it a feathery look.

I think it looks better now.

The first time you edit an image doesn't always give you a perfect result.

You need to make more changes until you are happy." This is the image before, and this is the image after.

Laura's used the clone tool to clone the fur on the chipmunk's head, and she's used that clone tool to cover parts of the bird's body.

This looks more feathery and realistic.

Fantastic, this brings us to the end of today's lesson, "Evaluating digital images," let's summarise.

Images can be reviewed to find ways to improve them.

Improvements can be made to images.

Multiple edits may be needed to get the end result you want.

Well, well done.

You've done so well in today's lesson, "Evaluating digital images.".
