Colour Correction in Photoshop

Hello friends, welcome to learnvern!

As we had learnt in the last session, how to design A4 size flyers, we also saw which size a flyer should be,

After that we made a portrait on which texts were written.

So, now in today’s session we will learn a new topic it's about color correction, in that will see

Fastest way to color correction your image.

Then, we will do Color correction of the portrait on which bright light is coming.

For fixing skin tone, there is a simple button on how can we do good skin tone.

We will learn that.

 How will Use selections for auto correct?

How to Match any color with major clicks. We will see these things today.

So let’s go to photoshop,

To clear the first topic, the fastest way to color correction your image.

So now you all can see I have opened an image in photoshop.

There is no need to do color correction on all of the images which are clicked,

Color correction is used when colors of an image are dull.

Now, you can see that in this image, colors are not that dull,

Then also we will try in a simple click so that we can do color correction.

First of all, I will take a curve tool from here, we will use curves.

And in curves, we will choose the middle one eye drop tool, not black one not white one but the middle one.

As we will click you we have to see gray color means, you have to select gray color in our image.

so here is the gray color which is on the road, as you will click on that, you will be able to see color correction image, you can see the difference.

why only gray color?

 Because our image has a presence of green color, when we put them down so by this way our image will be color corrected.

like for eg:-

we will close all this,

and i will choose darkish green color, we will put red at 0, we will use that green color,

we will increase the size of brush tool,

we will turn off the smoothing,

our brush we will be hard brush,

So I have chosen the green color. We will take another green color. We will take these both in different ways.

Which color did we get?

so we will get black color.

In the first image, we had seen that the value of the green color was 255, and the value of red was 0, and blue’s value was also 0.

So 0-0 will be 0.

255-255 that too will be 0 means it will be 255.

And 0-0 will be 0.

So when all the values are 0 then we will get black color. Like this, we got the black color, even though there is the same difference.

Now, in your image you don’t know where the gray color is, so how will you find gray color, which is the gray color ?

 so there is a simple technique,

When you will do ctrl+shift+N then, you will be able to see a new layer’s option,

where you can give any name as per your choice,

 like inplace of normal we can select overlay.

We will select “fill with natural color”, in 50% will be gray, then as you as we will click on ok, we will get gray color,

you can select normal as well.

 So this was one way.

There is another way also, like we will take solid color, in that we will write 128-128 so we will get perfectly 50% gray color. So here color fill is done.

There is another way too, we will select the image or canvas, then from here we will write 128-128.

Hope you are able to understand me!

so we will get a gray color. By this way you can also take gray color.

Now, we will use any of these techniques to get gray color,

After taking the gray color we will put this in difference, so here we can’t see the gray color which is the gray color so we will take a threshold.

In threshold, we will see which is the dark area means which is the black area.

Like here you can see that on the roadside, this area is darker.

The darkest area is considered to be the closest to the gray color here.

So we will make a path to remember,

And we will take a new layer.

And will create a path so that we can select the color from there.

Hope you are following me!

We will select color from here,

So whatever dark area is there it will come under gray color so if you are not able to find gray color, in your image then with the help of this you will easily be able to find gray color.

So all other things we will delete.

We had taken the color fill gray option, deleted that too.

We will take another color, in that we will select curves we will keep it as it is again we will select the middle one and we will select the gray color.

So this is the fastest way, to color correct our image then you set color from here what color you want bright or light.

Like this image is bright and dark.

So this is the fastest way to color correct your image.

After this, you can adjust your color as per your preferences, if you want to keep it as light or dark. For instance see this now the image is looking bright and dark,

So this is your fastest way to color correct your image.

After that, we will delete this layer of image because we don’t want this layer.

So now, you can see how much the difference has occurred in our image.

This original color green you will see. First it was looking like a golden type color and now it is looking like the original green color.

As you can see i have taken another image for color correction of our portrait,

So first of all, we go to filters and will select the camera raw filter. Its shortcut key is ctrl+shift+A.

 By doing this one new popup will open which is named as camera raw filter

so first of all we have a profile here

 Then, we have basic in that we can select temperature or tint, then we have exposure, contrast, highlights, shadows, whites, blacks, texture, clarity, dehaze, vibrance, saturation.

We have a curve for giving details and we have many options. We will see all these one by one.

So we will start with temperature, we will decrease some temperature so from that we will have some bluish tone when we will increase the temperature we will get some warm color, we will add some magenta color in that,

Overall, exposure is seen too much so we will decrease it.

What will happen with contrast ?

In contrast, if we increase the contrast, then the darkened area will be darker and if we decrease contrast so will get some brightness. So we will dark this image.

In highlight, we will increase the highlight so that the light which is coming on her neck will be bright.

We will decrease the shadow so the image could be dark. We will do dark because in this image glow should be maintained.

What will happen with white?

With white the image of whiteness will be increased and with black it will decrease.

so i will increase black as i have increased white so by this overall, it will be maintained.

Overall, texture of image should be maintained for i will give some textures.

What will happen with clearity ?

Skin’s clarity will be smoothed ,

 Are you able to see?

 Now you will see that skin is a bit smooth now.

What will happen With dehaze?

With dehaze, skin and overall image will be darker.

So for now I am whitening the image.

Then after we will not do anything with the curve, we will have a sharp overall image.

Because of noise, there are some changes, so we will sharpen the overall image and we will reduce noise.

Now, you can see with the reduction in noise how much change has occurred overall.

 We will reduce color noise also. Then we have color correction.

Before doing color correction, we should know some things that RGB’s opposite is CMYk. So red’s opposite will be cyan, green’s opposite will be magenta, and blue’s opposite will be yellow. So we will take care of everything. Now we have yellow, to reduce yellow we will add blue.

reduce red from saturation, we will give some orange tone so her skin looks good and will increase some green.

Then, will go in split toning, in that we will add overall highlights

then, will balance it with shadow because of shadow we want more yellow tone,

So now you can see that our yellow is now glowing more.

From optics we give some vignette so from four sides it will make the image dark.

We will not give distortion because we have clicked the image properly from the beginning.

 So in our image there is no green, we can make it greeny as well.

What will happen with that?

 The image will look good because every photo always has a little bit of green.

 we give some more vingitte with green.

I hope this much is clear to you!

So now, we will work with the curve which we had left aside to work later at the end,

so you can use the curve from here and from outside as well. Now this is a spot removal tool. We will use curve from outside which will be more preferable.

So this is a spot removal tool, like this is the area, which we don’t want, so we can remove this with a spot removal tool.

So you can give glow like this too. where there is green, it will be red. And if in red you want to have some glow effect then put green on blue and red on the other side meaning where you want.

as much you will increase that much glow effect you will be able to see. If you don’t want blue then, put red on blue and green on the removal part. Whatever You want to remove So it will be removed.

It's better, if we will not do this here and do it from somewhere outside.

For now, I am deleting this because we don’t need this now.

 With the help of adjusting brush we can adjust, i think there is no need of doing this.

Then comes, radial filter, we can use image as a filtering

Meaning the effect that we want, we will get here through this

In the circle which I have made, radial effect, we can do color correction inside of circle, whatever outside the circle will be not be counted as color correction

As you can see I can make this circle large or small and we can rotate it too. Let's make it small and increase the temperature on the face so the effect which is on her neck we can see that on her face as well.

So I will increase the circle more so that we can see that effect on hairs too.

now you can see the changes

So for now i will click on ok. So done with our color correction.

After this we will use a curve

As I have told you before, RGB's opposite is CMYk.

So red is with cyan, so to remove red from your image, you have to add cyan and if you want to remove cyan you have to add red.

if you want to remove green then add magenta and if you want to remove magenta then add green.

and if you want to remove blue then add yellow and if you want to remove yellow then add blue on the image.

The curve that is visible will have a white part on its left side, which means brighten area of the image *contrary*

Left hand side will have a darkened area, there you will get options for darker area.

Now you have a question in your mind: why is the curve so diagonal?

Let me tell you the reason.

As I told you Left hand side will have lighten part, and side will have darken part of the image.

So you cannot make the image darker, and cannot white the image from the right side, that is why it is a diagonal.

This line is diagonal because of this,

As you can see The RGB value, as i am telling you, i am taking pure white, 

its RGB value will be 255, 255, 255 and if I am taking gray then it will be 121, 121, 121.

If I am taking proper black, then it is zero zero zero.

And in any image which has RGB value, the image will have the same green part as red and the same blue part as green so all of them will be the same.

Wherever you take, our natural neutral color will remain the same. Their Values will be the same.

If you are changing this in RGB value, you are adding only darkness and brightness in the image.

We are not adding any color, as I told you in RGB that this color is a neutral color, and this curve will also work in the same way, so this is our brightness and this is our darkness.

This is the color of RGB so this is our brightness and darkness. 

We are working in RGB. That's why it is increasing /decreasing only our brightness and darkness in image.

If you want to add color then from here we will work with red, blue and green channel.

 Like I told you that if we want to add or reduce yellow color then we will go to the blue channel.

As soon as we come to the blue channel, then we can use curve and etc from here to know which, where and how much color is needed.

With that, we will not be able to check properly where there is more of blue or less so we will use this selection tool.

With the help of the selection tool, we will know what values are there in different areas

Now I want to decrease this brighten area in the image, so I will click here and hold it on click and as I will move it up. So you can see it is adding colors in the image.

If I do it down, there is a color difference.

See this blue has decreased and now blue is increasing.

Then we have a darker area, we will reduce it little bit and increase little bit in Brighten area.

Then we will add a little red from the red channel. And decrease a little bit.

So we have got the overall tone.

Now we will check the difference between the tone we added and the tone we got.

So I have added a green effect, so that we keep getting the overall feel of the image.

You can see it.

So this is the way of color correction by using a camera raw filter.

Next time we will see color correction of the portrait by hue and saturation, by levels and by curves.

So you must be able to see, I have taken a new image, For color correction, how to match perfectly with the skin tone.

So I have made a color palette. As you can see, We will match this color palette with our image. We will check first which color in the palette is matching with the image.

So for that first of all we need to take a curve layer.

As we select the curve, we have to select the middle one option. Not the black one and not the white one, but the middle one has to be selected, which stays 50% of gray in the curve.

We will select it, after selecting.

Double click it. After double clicking it.

 We’ll see which color matches the image and I think the second color will match the image. Click okay.

So it will ask save the new target color as default, do we have to convert it into default, so we will select no option.

So we have to click on that. Why was there no effect?

The reason why the color was not applied is because we had selected the mask here. And we have to choose curve space selection.

I'll do Ctrl Z then I'll select the curve space selection then double click on the middle. Then ok.

So it will ask save the new target color as default so we have to click the no option.

You guys can do it, but don't forget that in the next project, you have to make that 50% gray color. The value of gray is 128, 128, 128.

This looks more saturated .

Whatever our skin tone is, it is not perfectly equal for everyone.

Every time it differs.

We will double click it and select the color again then click on saturation from here where ‘s’ is written.

then move this slider down and try to match it and again select no.

 we will click on its brighter part or you can click on the darker part as well.

But it looks more saturated. So click again, double click, click this and decrease the saturation.

perfectly you can see the difference. Let’s try once again.

Double click, this color, go down. NO.

And you can change the skin tone like this. Double click.

If you don’t like this color you can choose this color also.

Control Z.

We will take a new curve and will put that curve below it, double click.

Select our skin tone in saturation, double click.

Color > saturation > down > no > skin tone changed !

And you can see the skin tone has changed.

 If you want to make it more white, then double click, let's turn on this, double click.

Select H from here. Select this and go to S.

H ?

 It is not picking colors because we were not using curves.

 Click on H - color, S - saturation, down.

If you want normally this color same to same.

Again double click, go on H, select this color.

Gradually increase a little bit on S, increase more a little bit.

So you will find color changes.

You can take any color in it.

We will reduce the saturation too much. You will get the difference.

I turned it off. This was our last one and this is our present one.

then you can add color correction and all to it.

red.

As we have learned the camera raw filter.

We will make a group of these two.

I am opening a lock and we will make a group.

Click on the group and we will match it. Press ctrl+E.

Click on filter then you will see an option camera raw filter.

We will increase its highlight and level.

We will brighten the darken and give some shadow to the shadow.

Then go to the basic option.

We will take the temperature to warm up, increase exposure, and take contrast as well as highlight.

The shadow will be a bit dark. We will increase the white one and decrease the black one.

Keep the texture a bit lower, clearity to suite the skin and dehaze to make her look darker.

I am whitening her skin, so we will apply dehaze.

So you guys would be able to see the difference, so this was our color correction.

You guys can use this to match any skin tone.

So we will try on another image.

I am opening an image.

We will try it on the same thing to make you guys know how it works.

I got this image matched with our color palette.

Take the curve tool and put it under our color palette.

So that thing does not affect the color palette.

We will select the curve from here and double click the middle one option.

So our H is done.

First we will match the skin tone and know which color matches her skin tone.

We will take the second color.

Select no.

So the saturation is too much.

So double click it, click on S and decrease the saturation.

 You can see the difference now.

Still, if you feel that saturation is more, then you can reduce the saturation more.

 You can see the difference.

If you do not want this color and want this one, then select it and decrease its saturation also.

 And give it color.

So simply your work will be done in two or one button.

If you want to make it black. If you want to match it with the black skin, then you can do that too.

So now you must be able to watch the difference in skin.

So this was my purpose to explain to you, how to match with the skin tone in one button.

So now you can see. I have opened another image.

So we will do the color correction with the selection.

So first of all we'll look at one more thing. We will select the curves option.

What difference does this auto correction mode give?

Simply Click on auto. What will it do?

The auto option will change the brightness.

Press ctrl+Z. You can see the three dots.

I'll click on it. auto options will pop up. Here you will get many options in it.

like find dark and light colors and enhance per channel contrast, and enhance monochromatic contrast.

So I am taking this in “find dark and light colors” and saving as a default.

Now this will go in auto correct so taking ‘find dark and light colors’.

Then click on ok.

You can see it.

It took bright and dark colors.

So now I don't want it.

I'll take the rectangular marquee tool. I don't want to affect her skin. 

Only on her clothes and here only. I will ask it to select colors from here only

So I made the selection.

So let's select the curve option with the selection and that will create the mask.

And do auto in it so It will work on that part only.

Because we have kept the mask selected and you can simply also turn it off.

So the difference will be visible on her face as well.

I am closing this.

I'll take another curve then click on the auto option, this time enhance brightness and contrast.

Save as a default and Click on ok.

Let me show you the difference between both.

This and this, this and this.

So you can see the difference.

So this was our auto correction with color correction.

You can simply delete it by dragging, If you don't want a mask.

 if you want to do it on skin. So like we did before. Double click it.

Click where you want the color tone.

So this was the selection mode of auto correction.

As you can see, I have another image.

With which we will do our color correction in three simple clicks.

Which means to match with our character meaning with cut out lady we will match this image

So our subject should be cut out.

So for that we will use copy meaning curves. We have these three options in curves.

The first is for the dark tone.

The second is for the midtone.

The third is for the shadow.

So first of all we will click on the most darken area, so that is the dark area, this one .

It will do all the work.

For that we have to use a clipping mask.

Click it, double click it and select the darken area.

Click on H,

Select the dark area.

Then click ok.

Save as default for now.

Then select the part having a gray tone.

 Double click on gray tone.

Gray tone, ok, yes default.

Then we will select the highlight, this one, double click on it. highlight , Click on ok, yes .

Now we will come to our image.

Again same three things on our character, with our subject.

So this is the subject, its darken area, this one, ok, yes.

Then press ctrl+Z.

Select this, Double click it ,darken area, ok.

After that from here we will select our brighten area.

So it is this one.

select her grayish tone. So this is a grayish tone.

and This is the darkest tone here.

So in three simple clicks our color correction is matched with the image.

After this you guys can still add a lookup option.

Click on color lookup.

So this is the color lookup. This will match your Image with lookup.

As we have done color correction. Our subject has also matched with the background.

So thankyou for joining us.
