In the video above, I will show you how you can add contrast to your images in different ways using Affinity Photo, right from a simple contrast adjustment to a more professional way of adding contrast to your images. You can also use the method if you are using Photoshop, with just a little modification.
We will be using an image that I captured on my trip to New Zealand. I captured it a little downstream from McClean’s Fall in the Catlins Conservation Park.
As usual, when you capture images in Raw-format, they come out a bit flat. So, I want to add some contrast to make it pop a bit more and add some depth to the image.
There are several different ways to achieve this.
The simplest way is to simply add a Brightness/Contrast adjustment layer and increase the contrast slider. In this case, I think that setting the contrast slider to around +24 % looks nice.
However, this method doesn’t give you much control of how and where the contrast is applied to your image. For instance, a Brightness/Contrast layer will apply an equal amount of contrast to the highlights and the shadows.
Method 2: Using a Curves Adjustment Layer To Add Contrast
With a curves adjustment layer, you get more control of how you add contrast to your image.
The left side of the curves adjustment dialogue represents the shadow areas in your image, while the right side represents the highlights.
A typical way to use a curves adjustment layer is to make an S-curve and then make your corrections from there if, for instance, you went too far with the shadows.
When you use a curves adjustment layer to add contrast, you can, for instance, lower the shadows more than you raise the highlights, so it is more tailored to the tonal values in your image. This is not possible when you use the more basic Brightness/Contrast adjustment layer we saw just before.
The third method is actually just a more precise way to use curves adjustments, where you target specific areas. However, it also gets a bit more complicated from now on, but you will often get better and more professionally looking results if you use this method. It gives you more control of where you add contrast and how much you add to a particular area.
For instance, you might want to increase the contrast in the shadows or mid-tones, but not in the highlights.
Begin by making a selection of the shadows.
Go to Select > Tonal Range > Shadows.
Next, add a curves adjustment layer. Because of the active selection, the curves adjustment layer will only affect the shadows.
By lowering the curve on the left side and raising it in the right side, we can create more contrast that is targeted to our selection only. And currently, this is the shadow tones in our image.
Next, up we can target the mid-tones by making a new selection of the mid-tones.
Go to Select > Tonal Range > Midtones.
With the mid-tones selected, add another curves adjustment layer and change the curve to set how much you want to darken or brighten the “darkest” part of the mid-tones and how much you want to darken or brighten the brightest part of the mid-tones.
Finally, you can do the same thing for the highlights, if you need to address these specifically.
Go to Select > Tonal Range > Highlights.
You don’t need to create the curves for both shadows, mid-tones, and highlights if you only think that you want to increase the contrast in the shadow areas in your image.
You don’t need to use this more complicated method if you find that applying a curves adjustment layer will give you the contrast you think is right for your image.
But it does give you much more control over how your image will look when you make the adjustments more specific.
In my Affinity Macro pack for Photographers, you can use the Pro Contrast macro to make these advanced contrast adjustments where you target shadows, Midtones, and highlights separately, with just a single click. After this all there is left to do, is to adjust the curves for each of these to your image and to your liking.
If we take a look at these methods for adding contrast, that I have shown you here, we can see that they lead to quite different results.
Towards the end of the video [around 5:37 minutes in] you can see a comparision of the three different methods used in the video. To an untrained eye, the differences can seem small, but specially the shadow areas in the image benefitted from the advanced targeted approach to adding contrast.
As you can see the more control you have the more you will be able to fine tune the contrast you apply to the specific image photo you are working on.
Which method you use is up to you, but as you get more and more familiar with software like Affinity Photo you will really appreciate the amount of control you can get over the photo editing process.
As I mentioned at the top of this post, you can also use this method in Photoshop. However, to select tonal values, like shadows, mid-tones and highlights, you need to use luminosity masks. Over at Lightstalking.com you can find a great explanation on how to use lumonosity masks in Photoshop.
If you don’t want the hassle of creating the luminosity masks in Photoshop, you can use the PRO Contrast Action, from my Photoshop Actions for Photographers Package.
