How To Become A Tone Curve Master In Lightroom www.sleeklens.com

Hi everyone, today I want to take a bit of a detailed look into the Tone Curve in Lightroom.

I believe I have touched upon this subject a few times just as a by-product of the subject that I was actually discussing so I felt the need to make a Lightroom Tutorial on this subject and just throw it out there for you all to learn from and use as a guide if you so feel like it…or are in desperate need for a guide as I have been many many times in the past haha.

Ok so if you open up your Lightroom, don’t worry for right now this second you won’t need an Image just the program.

Take a look at the top right-hand side for the word ‘Develop’ and click on this, in this section is where you will find the Tone Curve.

If you can’t find the Tone Curve then in the Develop section right click over one of the other options and a menu will pop up.

Make sure the Tone Curve has been checked!

Click on the drop-down box just to check it out, just click on the little arrow to the right of it.

Then you will see a few little sliders and the main box graph with the line running slanted from right top to left bottom.

Now out of the two sections there, the one with the line running through it and the sliders at the bottom, these can be considered the same thing but applied in a different way.

I would consider the main graph to be easier to use but when I say that I mean by like about 1%, for best results and I say that loosely once you know all you need to know with this Tool, then you’ll end up just mixing the two up using whatever at the time you feel is more appropriate which again, I say very loosely.

Ok so one with the description of what the Tone Curve does, so, the Tone Curve is used to adjust the…

Shadows

Mid-tones

Highlights

Making them either Lighter or making them darker without affecting the other two at any which combination, so if I was to adjust my Shadows my Mid-tones and Highlights will be safe so long as I don’t make a huge drastic adjustment which 99.9% of the time you will never do unless it is very specific to what you are doing.

Let’s just do a little demonstration I’d like you to follow along to.

It’s time to grab an image to use, any image will do for this demonstration, you can use yours or any interesting free stock if you desire.

So look at the image above on the Tone Curves the main box with the line running through it, that side of the box works as follows when you shift the values.

At the bottom, it is darker and as you move towards the top it gets lighter.

The same goes for the bottom as well only the bottom is actually marked that you can see it.

Now with your mouse just run your pointer over the line to you see the little diagram it gives you, treat this as a kind of a predictor line as to what will be effected on your graph.

So now you know little basic lets now click on the top slider which is highlights! as you hover your mouse over the slider you will see the same predictor appears on your graph just as before.

And when you move it you will notice the line on the actual diagonal line move just as the predictor pretty much shows you as we just discussed.

By the way, if you want to Reset everything if you have played around with a few of those sliders etc. which you are totally free to do you can just click on ‘Reset’ at the bottom there just beside ‘Previous’

So the general rule is, up is lighter and down is darker and left is darker and right is lighter.

Now you will notice Lights and Darks just below Highlights, consider these the Mid-tones split into two.

So you know that up and down darkens and lightens and left to right darkens and lightens.

Below I have just added a few examples in the Images of each so you can see just to really drum it into you.

Ok so the next thing that we’ll look at is just above the Region sliders [the ones we just messed with], so at the very bottom of the graph box you will see that there are three slider tabs as well, what these do is, say if you take the furthest one as shown below and move it to the right…

And then you repeat what we just did with the Region sliders again hovering over the highlights slider you will now see that the area prediction will now be a different shape, so as you move these about you will find that you get different results according to how much you have opened or closed those sliders.

So essentially you are making, for example, the Highlights that are affected limited or more in general.

This applies to all the region sliders.

In simple terms if you wanted to affect the shadows just a little you could slide the shadows tab which is the first out of those three, to the left to restrict it, then you would go back to the Region sliders and work that way back and forth etc. and take note that when you restrict one, you will get more range out of the opposite side to it, so with the shadows restricted you will now have more range of the mid-tones.

Ok so let’s now move on to the Point Curve which a lot of people consider being more effective, as I said before they’re both similar, so in the end choose which you prefer and work the other in slowly until you are using both, I guess that would probably be the best way to do it, I think from memory I actually started off with the Point Curve due to coming over to Lightroom from Photoshop and just because you could click and grab and I basically knew nothing of the actual inner workings of the Tone Curve in Lightroom at the start.

The way the Point Curve works is you have to click and hold on the diagonal line on the graph [so that’s the inside of the square]

But first! you must click on the little icon that closes, you will see the little icon to push in the image below, it looks like a little micrograph and when you hover over it, it will say, ‘Click to stop editing Point Curve’

So if I wanted to make my shadows darker I would hover my mouse over the area that I wanted to effect, then I’d click on the diagonal line as shown.

You can put several points on the line where you want to affect it, and then you can play with it that way, where you put the points on the diagonal line is up to you but I would say that you should think of where you put the points as the same as in those 3 slider tabs in the region sliders.

Then as we talked about before, up is lighter and dragging down adds darkness.

Note as well that you can also click on your point and move it side to side as well, you get a full range out of these points.

If you end up unhappy with where you have placed one of your points then no worries all you have to do in that situation is to right click on the point, then a pop up will appear, in that you will see ‘Delete Control Point’, hit that and the point will now be removed.

And of course, if you end up with a total disaster which can happen from time to time just click on flatten curve and that will reset your curve back to the start again.

Now we have the basics of the Region Sliders and the Point Curve let’s take a look at a few more in-depth areas of the Tone Curve, to start let’s look at a couple of the Presets they have available for you.

Take a look just to the left of the little Icon we clicked earlier on the Tone Curve Tool and you will see the words ‘Point Curve’ and most likely depending on what you’ve been doing you will see the word ‘Linear’ on that, click on that and you will see there are a couple more options available to your there for your Contrast.

Click the each there now just to see how they affect your Image.

Then to reset that just click back on to ‘Linear’

This same option is available to you in the Region drop-down also so remember that if you ever use that as your primary editing option.

Next, if you choose your own, as in you make your own points etc. you have the chance to save it if you like it and it works for a certain type of image.

So say you have a whole batch of images but you will be doing them over different dates, so you will get some now, some later when they’re done and some may be at the end of the month, but you figured out a great edit that you really like and that works for a broad range of your images if not them all, then in that Presets box we just looked at you will now see the word ‘Custom’ click on your box again and at the bottom there is an option to ‘Save’

Then just choose the name that you think best fits [Example: Canyon Shadows] or whatever you are doing and save to the default location.

Ok, now I’m just going to reset back to Linear.

Next, we’ll take a look at an option called ‘Targeted Adjustment’

So if you look at the top left-hand corner of the Tone Curve box you will see a little circle with a dot in it kinda like a Target funny enough almost as if Lightroom had that planned eh.. lol anyway, the way you use the Targeted Adjustment Tool is first to click on the little target to activate it, you’ll know it’s activated when you see two little arrows at the top and the bottom of it.

Now all you have to do is click on a specific area that you would like to either brighten or darken, so if you look at my image on the car at the minute it I feel that it is very washed out looking and I feel I can strengthen that color.

So all I do is click on the car and either drag up or drag down till I see an improvement if any at all if you have to try a few times then, by all means, go ahead with that and try a few different points.

Then as before if you are unhappy with a certain point for whatever reason you can right click on the point and delete it as we did before, you also have that Flatten Curve option too to reset totally.

Just note that generally when you click on a color and edit it the rest of the image will be edited too, to a lesser extent so just watch out for that also.

You are also able to do this to different areas too, you don’t have to just stick to the one color and that’s that. So, for example, I feel that the edit I just did for my image has blown out the whites a little bit too much, so I’m just going to click on the whites in the sky and see what options I have with the Targeted Adjustment Tool.

Remember for this you have a circular range, so you can move the point up down left or right!

So after trying out a few options, unfortunately, to balance that White in the image it drains the Green of the car and the other images too so we will have to start looking into channels next to enhance colors!

Ok let’s look at Channels! so scan your eyes over to the Tone Curve box and below the graph, you will see the word ‘Channel’, beside that then you will see RGB which stands for Red, Green, Blue. [This is what your image is made up of]

So when you click RGB you will see those colors listed, each of those colors are a different channel, so if you were to click on Red and apply everything that we already learned to the Graph when isolating whatever color that you want to work with then you will be able to brighten, strengthen, make darker etc. etc.

So I talked about how I wanted to make the Green stand out a bit more as I felt it was very saturated.

To do this I will just click on the word ‘Green’ in my menu there.

Because each image is different I will not be able to point you in the direction of exactly what to do so all I can say here is, keep it subtle and with what you know already just trial and error until you find something that you like, sometimes you won’t get a very good result and you will probably have to move to other tools but hey that’s Lightroom for ya and that’s how the games played.

But it’s not all over yet because we can do this to several colors, so when I adjusted my image took on a very Red looking tone, well to fix this sort of thing I suggest just going through each channel until you reach a happy medium.

Another cool way you can try is to create 3 points, so, for example, I could take the top point on the right, create another in the dead center and in the middle of that I can create the third, in the middle, then when I click the middle point and move it about I will only be affecting that exact area, so essentially you are isolating, for example, the shadows or a mixture of 2 elements like the shadows and mid-tones.

You can place these points anywhere you want, I would suggest as I said a second ago just trial and error it and as you gain more experience you will get a natural feeling for this sort of thing and you won’t even really think about it anymore as you work you’ll just do it.

The last thing that I’m going to talk about using the Tone Curve is how to use it for Toning Black and White Images.

So we’ll take this scenario as an example, imagine you have to create an old western look to some images, well the way to do that is to first change the image to Black and White.

To do this, first as you are working along with this Tutorial I’m guessing, so Reset everything by hitting that reset button at the bottom of your screen on the right.

Then convert the image to Black and White by clicking on the little B & W tab just below the Tone Curve Graph, you will see it on the right-hand side of the example image below if you are stuck but I’m sure you’ll see it.

Ok, we’re ready, so a little color theory to get us going on this color toning business.

Old West images are generally brownish yellowish, so how to get this tone onto my image when we don’t have those colors, well we are now dealing with opposites/complementary colors and a little mixing theory.

Mixing first, to get brown you have to cross yellow and red and then darken it, really brown is just dark orange.

So to add this tone first I have to add yellow, well yellow is blues opposite so we click right at the top of the diagonal line and pull it down to add the yellow tone, this works for all the colors, when you do this exact technique for the other two colors you don’t exactly get the opposite you’ll get more of a pink and cyan but using all three you can generally get the color you are looking for.

To finish up I just add that last little bit of Red to push the color towards Brown.
