Hello, my name's Ms. Powell, and welcome to Computing.

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

In today's lesson, we are going to be learning how you can recolor digital images.

We're also going to be talking about how this can change the way you think or the way you feel about the image.

Let's get started.

Welcome to today's lesson from the unit, "Photo Editing." This lesson is called "Recoloring Digital Images." By the end of today's lesson, you'll be able to explain the impact of changing the colours in a digital image.

We'll be using these keywords throughout today's lesson, let's take a look at them.

The first word is effects, effects.

This means the changes that are applied to give a different result.

The second word is colouring, colouring.

This means changing the colour of something.

This lesson is fit into two sections.

In the first section, we'll look at describing how colours make you feel and think, and in the second section, we'll look at applying colour effects for different purposes.

Let's get started with the first section, "Describe how colours make you feel and think." When you take a photo, you need to think carefully about the colours and light levels in the picture.

Once a photo has been developed into a paper copy, you cannot change the colours or light levels in the photo.

You can use digital devices to change the colours and light levels in digital images easily.

You could use a tablet, a laptop, or a mobile phone.

How has this image been changed? What do you notice here? I have two photographs, an original and an edited version.

Some things are the same and some things are different.

Pause a video so that you can take a look at the two pictures and have a think how has this image been changed.

The colour of the image has been changed using a sepia colour filter.

A sepia colour filter uses different shades of browns to render a photograph.

Do you see how the green leaves are a shade of brown, and likewise, the green grass.

How has this image been changed? I have another change to my original image.

What do you notice that's different? Pause the video and take a look at the two pictures.

Try to work out how has this image been changed.

The brightness of this image has been changed.

It looks to me as if the brightness has been increased in this picture.

I can see that because the light looks much brighter between the trees and also on the grass.

Photos and feelings.

Sometimes you edit a photo because you want to change what someone thinks or feels when they look at it.

You can achieve this using colour and light effects.

Effect names: Original, black and white, brightness and contrast, hue and saturation, sepia, vignette.

If we look at these effects, we can think about how it's changed the photograph.

The original photograph is how you took the photo on the camera, it's not been changed.

In the black and white photograph, the colours have been replaced by different shades of black and white.

Do you see that the green leaves on the trees and in the grass are now a shade of grey? If you look at the effect, brightness and contrast, you can see that the areas that are bright are even brighter, and the areas that are darker get even darker.

This is contrast when there's a lot of bright things and a lot of dark things together.

Let's look at hue and saturation.

So hue means colour, and in this picture, the colour has been changed.

The leaves are now blue, which is very different from the original.

Saturation is how strong the colour appears.

In this photograph, there is a strong saturation of colours.

The blues are very vivid.

In the effect, sepia, the colours are replaced with shades of brown.

In the effect, vignette, you can add an area of darkness around a central point.

Can you see that the bridge has a circular area of darkness around it? These effects can be used on digital devices to change photographs, and they can be lots of fun to play with.

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

Which photo has the sepia effect applied to it? And remember, sepia makes the photo a reddish-brown colour.

Do you think it is A, B, or C? Pause the video to take a look at the photographs and try to work out which one has had the sepia effect apply to it.

The answer is A.

This photograph has a reddish-brown colour.

The original colours have been replaced.

I'd like you to try another one.

Which photo has the vignette effect applied to it? Vignette makes the edges of the photo darker.

Do you think it is photograph A, photograph B, or photograph C? Pause a video to have a look at the photographs, and try to work out which one has had the vignette effect applied to it.

Did you get C? Well done for having a try.

In photograph C, the edges of the photo look much darker, that is a vignette effect.

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

Look at two of the photos provided on the next slide.

They are the same photo, but the colours and light have been changed.

Think about, one, how you feel, two, what you think, three, how you would describe the picture, four, where you think the picture would be used.

Here are the photographs that you can use to discuss what differences did you notice? Remember, you're thinking about how you feel, what you think, how you would describe the photo, and where you feel this photograph would be used.

For example, the photograph that I have seen using the black and white filter makes me feel a bit melancholy without the colours, the bridge appears a little bit lonely.

Let's take a look at some of the photographs.

Does everyone feel the same about a photo? This is Alex and Alex says, "This photo makes me feel scared.

The black edges cover part of the photo and make me feel like I'm walking into a dark hole." The vignette effect on this photograph made Alex feel scared.

The same effect may make different people feel different ways.

This is Sophia, and Sophia says, "This photo makes me feel excited.

The vignette effect makes the edges of the photo darker, and I can't see what's around the bridge, so it makes my imagination go wild." So here, Sophia felt very differently about the photograph than Alex.

This is Laura, and Laura says, "This photo makes me feel excited.

It reminds me of a bridge I used to walk over on my holiday.

On the other side was a fairground with lots of fast rides." It's interesting to see how the same image can make people feel in many different ways.

Well done, you've done so well in the first part of today's lesson, describing how colours make you feel and think.

Let's move on to the second part of today's lesson, "Applying colour effects for different purposes." Let's watch a video on editing photo colours and effects.

It'll start now.

Let's take a look at these colour effects, original, black and white, brightness and contrast, hue and saturation, sepia, and vignette, and talk about how you might be able to find that in software such as paint.

net.

There are different tabs that you might have, such as Adjustments and Effects.

If you go to Adjustments, you can scroll down and you can find black and white, brightness and contrast, hue and saturation, and sepia here.

Then if you go to the Effects tab, you can scroll down to Photo, and vignette is right at the bottom.

I've got a question here for you, I'd like you to help.

Which photo is relevant for this purpose? "A day exploring the woods with a friend." Which photograph do you think would work well for this? Do you think A, B, or C? Pause a video to have a try.

Did you get B? B would be the best photograph for exploring the woods with a friend.

A looks very artistic, and C looks like a photograph from a long time ago.

Whereas B would be the best photograph, which shows the joy of exploring the woods with a friend.

Which photos are relevant for this purpose? "A long, long time ago." Pause a video to have a little look at the photographs, A, B, or C.

Try to work out which ones would be relevant for "A long, long time ago." Well done for having a try.

I think both A and C would be relevant for "A long, long time ago." They both look as if they were photographs taken in the past.

Which photograph is relevant for this purpose? "Something unexplained has happened." What do you think, A, B, or C? Pause a video and take a look at the photographs.

I think C would be the best fit.

Using the vignette effect gives a feeling of something unexplained happening.

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

Use the images provided, add colour and light effects so that they are useful for the following purposes: A happy, fun-filled day.

What kind of effect would be best for that photograph? A place where pixies would live and magic would exist.

How can you change the effects for that purpose? A dark and dangerous place that you're nervous about exploring.

Can you spot any other tools that might change the colouring of a digital image that haven't been mentioned yet? Pause the video to try the task.

Explain the choices that you made when editing your image.

Try to describe why you made certain choices and which tools you used to achieve this.

This is Sophia, and Sophia says, "I made the happy image bright by changing the brightness and adding the posterize effect." Well done, that brings us to the end of today's lesson, "Recoloring Digital Images." Let's summarise.

Digital images can be recolored.

The colouring of an image can evoke different feelings and thoughts.

Computers make it easy to experiment with different colour effects.

Well done, you've done really well in today's lesson.

I look forward to seeing you in the next lesson.
