Topaz Tutorial: Editing Landscapes with Miroslav Petrasko

Landscape photos are quite different from cityscape photos. If you are not shooting right into the sun, you usually have much less local contrast and extreme differences in brightness in the photos. You can’t just take one and be done with it, so some editing is always required–even if it’s only to fix lens problems.

Sharpness is really important in landscape photos. Together with a bigger depth of field, it makes landscape photos stand out more. Here is where Topaz Sharpen AI can come in handy.

A Stunning View

This is a view from the Five Fingers lookout platform in the Austrian Alps, high above the town of Hallstatt. It was taken during an overcast day, so while it’s properly exposed, it’s a bit dark, hazy and bland. I won’t go through every edit I did on these photos, but will point out some of the most important techniques to help you get more from your landscape photos.

Original Image (Click to view at 100%)

I took three exposures for this photo in 1EV increments. I could have gotten away with just using a single exposure, but I knew I would want to lighten and darken certain areas. So, having a proper exposure of every area makes for a cleaner photo than one that was over or underexposed in post-processing. Here are the two additional exposures.

There is a photo post-processing technique called matching, which I’ll show you below. By doing so, you end up with a nice even blend that looks like one seamless photo. The idea behind it is to take the RAW files as smart objects into Photoshop and blend them together to get the desired exposure everywhere.

Once this is done, you go back into the RAW editor and tweak the RAW files, to create a similar look for each one. You do this by mostly tweaking the exposure, highlights, and shadows. You can also add enhancements like vibrance, dehaze and clarity to the RAWs, to make further editing even easier.

I blended the photos into one by using layer masks and luminosity selections. Once done, I matched the exposures and added vibrance, clarity, and dehaze to them. Above is a screenshot of the blended, tweaked underexposed RAW and below is how it looked afterward. You can see that the blend has almost no contrast to it. That is normal because when you remove highlights and shadows, you also remove contrast.

From this point on, all of my edits are just tweaking brightness and contrast, maybe a bit of saturation here and there. Usually, you don’t need to edit saturation at all, as adding contrast makes the photo more saturated on its own. But as this was very overcast, I wanted the foreground color to stand more.

You can see in this Photoshop screenshot all the layers I used and how I only painted them by hand to the areas I needed them in.

Best Practices for Sharpening

With this done, we’ll move on to sharpening. There are three things to consider here. Firstly, the whole photo should not be of the same sharpness. Our eyes are drawn towards sharper (and brighter) areas so you can use that to draw it towards your main subject. In this photo, that would mostly be the foreground and the middle area around the lake.

Secondly, not everything should be sharp. For instance, you would not expect the peaks in the further background to be as sharp as the closer ones. And you wouldn’t expect to have much darker clouds than the rest of the scenery.

Thirdly, it is good practice to resize the photo to your final desired resolution and only afterwards sharpen it. 

Topaz Sharpen AI

Let’s sharpen this photo now. We need to merge all the layers into a new one, and then use Topaz Sharpen AI from the plugin menu. There are multiple processing modes available in Sharpen AI to target specific problems–Sharpen, Stabilize, and Focus.

With a landscape photo, you can use all of them. For instance, if you got your focus a tiny bit off, you can try the focus mode to return some sharpness to the out of focus areas. Or perhaps you had a bit of wind come through and the foliage moved. In that case, you can try the stabilize mode.

For this photo, let’s go for the standard Sharpen mode. The standard settings look a bit strong for this photo, so let’s move the Remove Blur slider to 0.4. You can see a few areas in comparison below, all are at 100% zoom.

We can remove the sharpness from the areas where it’s not needed, and tone it down in others. You can choose to go back to Photoshop and remove the sharpness from the clouds, if you want them to be a bit blurry and soft. I also removed the sharpness from the peaks in the distance and toned it down on the peaks that are close. Like this, there is a nice progression, with the sharpest things close to you, losing the sharpness the further away you look.

Topaz Tutorial: Editing Cityscapes with Miroslav Petrasko

When editing cityscape photos, Topaz software can be a big help. There are many sharp edges and details in cityscapes you’ll want to preserve. To achieve this, you can get a lot of help from Topaz DeNoise AI and Topaz Gigapixel AI. Both are useful with reducing noise while preserving sharpness and adding clarity. And today I will show you how.

Cityscape Fireworks

Let’s look at one of my cityscape photos with fireworks. When I capture photos, I prefer to do multiple exposures, so I can blend them later in post-processing. Unfortunately, this does not work that well with fireworks. So, there are two ways I can approach it: I either take separate photos of the scenery before the fireworks and blend them in, or I just work with a single exposure and try to make the best of it. Over the years, I’ve settled on the second option.

Working with only one exposure creates some other issues though, namely noise. Since you can’t predict the brightness an explosion will create in a scene, you will end up with a lot of underexposed photos. You don’t want to overexpose, since you can’t easily fix overexposed areas. What I like to do is double-process the photo: I create a copy of its RAW file and process it once for the highlights and once for the shadows. Then, I put them back together in Photoshop.

Let’s look at a photo to understand it better.

Fireworks in Budapest

Base RAW Image (Click to view at 100%)

This fireworks photo was taken in Budapest, Hungary, during the St. Stephens celebrations there. It’s the biggest holiday in the country and always ends with huge fireworks over the Danube River.

This is the base RAW image I captured. As you can see, while the fireworks look a bit overexposed, the foreground feels dark. So, let’s break it into two files and edit them both.

The photo above is edited for highlights, where I toned down the bright areas a bit.

The photo below is edited for shadows, where I opened the dark areas a lot. 

(Click to view at 100%)

Now I can put them into layers in Photoshop and using luminosity selections, I select the shadow areas and paint in the brighter version.

While I won’t focus on this technique here, you can find a detailed description on my blog.

I also did a few tweaks to open the shadows even more. One thing I like to do in photos like this one is to brighten the lightest areas of the fireworks, to make them stand out even more.

Now it’s time to fix a few issues that were introduced with this post-processing. Since we had to brighten the shadow areas, they now have much more noise than the rest of the photo. This can be fixed by using Topaz DeNoise AI. We can either use it on the whole photo or just on the parts where it’s mostly visible.

Noise Reduction with Topaz DeNoise AI (Click to view at 100%)

Let’s open the image in the Topaz DeNoise AI plug-in. The automatic processing worked quite well here, but let’s also manually move the Remove Noise slider to 0.25 to get rid of a bit more. I like it when the clouds and smoke in the sky feel soft, so I want to remove the graininess that was created during editing.

Below is a comparison of the results of DeNoise AI in multiple areas of the photo. All examples are at 200% zoom. It looks good, so I will keep it for the whole photo as it is.

We need to save the photo in Photoshop before moving on to the next step. Let’s save it as a TIFF file, as a copy, and without layers.

Now, let’s add some clarity in the photo. While Topaz Gigapixel AI is an image enlargement solution, and not specifically designed for this task, it can be used in this way. What we want to do is use oversampling here. Basically, we’ll enlarge the photo using Topaz Gigapixel AI, and then scale it back down in Photoshop.

I open it in Gigapixel AI and enlarge it by the 4x multiplier.

The other settings can stay as they are since they will have little effect when we return the photo to its original size. But if your photo is a little out of focus, or the camera moved while you were taking it, you can try and use a higher setting for the Remove Blur option. Click “Start” to begin the image enlargement processing.

Once the process ends, I open the result back into Photoshop. The original photo’s width was 5,161 pixels. The new one is 22,000 pixels (that’s the limit for a TIFF file). This can now be resized in Photoshop back to the original 5,161 pixels to get our clearer result.

Below are a few specific areas of the photo to see it before and after. All of these are at 200% zoom. As you can easily see, the details are much better, and the overall clarity has been greatly enhanced. Since Topaz DeNoise AI also adds a bit of clarity, you can see their cumulative effect.

We don’t need to use this on the whole photo, with areas where there are no details — we don’t need more clarity. If we just overlay the result with the original edit, we can use masking to apply it only to the areas where it is needed.

Clean Up in Photoshop (Click to view at 100%)

We are almost done here, except for a little cleanup. The trees in the top left and the light streaks in the bottom left have to be removed, together with few dust spots. Once it’s done, we have our final, enhanced and improved result below.

You can drag the interactive, white slider bar across the image to see the improvements.

Editing Workflow

This way of post-processing works on most cityscape and similar photos. Usually, with cityscape photos, you have bright areas (e.g. artificial lights, windows, sky) and many dark shadow areas. Either by splitting one RAW into multiple images, or by having taken multiple exposures, you can properly expose both. By putting them together, you will create a nice, evenly-exposed photo that you can then reduce noise with Topaz DeNoise AI and add clarity with Topaz Gigapixel AI. I prefer my photos to look perfect at any size and this workflow allows me to achieve that.

Here is one more example below, where I used Topaz DeNoise AI and Topaz Gigapixel AI. You have here a full image and then a few before/after detail shots.

Sounding Off on Noise in Images


What do all the images below have in common?

Low light + High ISO  = Noise²

They all contain some amount of noise. But what causes noise and how can you avoid it?
Albert Einstein by Arthur Sasse

In a galaxy far, far, away… the (extremely) wide depth of field causes an unavoidable amount of noise.

Pillars by NASA’s Spitzer Space Telescope

A legendary slam dunk in motion leads to noisy crowds and a noisy image.

Michael Jordan by John Swart

So, what do all these images have in common? Well, besides all being very iconic?

…They all contain some level of noise.

Perfect conditions may not always exist to avoid capturing a noisy image, but here are a few pointers to help during your next shoot and post-processing.

Understanding What Causes Noise and How to Avoid It

You can generally point a finger at a high ISO setting if you’re experiencing noise in your images. High ISO is the most common contributor to image noise in photography.

The ISO setting defines how sensitive your camera sensor is to the amount of light present in your scene. It can also vary by camera model. A standard range of ISO is typically between 200 to 1600.

The lower ISOs are ideal for well-lit or sunny environments, or when your camera is stationary.  

A higher ISO setting will cause the sensor to be more sensitive, allowing you to compensate for specific scenarios, but will also create more noise.


Uses and Benefits of High ISO Settings

A higher ISO enables:

–Faster shutter speeds to freeze motion (e.g. 1600+ ISO for indoor sports photography)
–Better performance in low light (e.g. nighttime cityscapes, Milky Way shoots, dimly lit indoor shoots)
–Reduced image blur when shooting handheld

 

Other Factors Affecting Exposure


In conjunction with ISO, there are other factors weighing on exposure, like aperture. Think of aperture like the pupil of your camera lens.

Much like our very own pupils in our eyes and how they respond to light and dark environments, you can adjust the aperture to allow more or less light into your camera’s sensor. The smaller the aperture, the less light is allowed in and the larger the depth of field. A larger aperture allows for more light and a more shallow depth of field.
 
Measured in fractions, the smaller number is actually a larger opening, so f/4 is bigger than f/16, with the “f” standing for the focal length of the lens.

And finally, the last major factor in exposure is shutter speed, the duration in which the shutter is open, exposing the sensor. Measured in a fraction of a second (e.g. 1/125, 1/500), shutter speed can compensate for images that appear too light or dark at your selected aperture.

When you double the ISO (e.g. from 400 to 800), your camera only requires half as much light for the same exposure. For example, if the shutter speed is 1/250 at 400 ISO, upping to 800 ISO will produce the same exposure at 1/500 second (with a static aperture).

Working in tandem, these three settings will help you develop better images and make post-processing simpler. But for those necessary shots in less-than-perfect scenarios, we have a new solution to reduce noise and restore your photo to its intended glory!

Meet our latest AI-powered solution, DeNoise AI.

 

How does DeNoise AI work?

After months of training and testing, we are now able to use a bigger AI network that handles more varieties of noise.

All you have to do is import your image. DeNoise AI will target the noise in your image and intelligently apply the best solution for removing it without sacrificing too much detail loss.

Though we’ve created DeNoise AI to be an easy, automatic solution, there are three adjustment sliders that allow you to make manual edits beyond the automated detection. With the Remove Noise slider you can apply even stronger noise reduction. Pushing the sliders to the extreme level will not give you the best output all the time. If your noise level is low, then keeping the slider in the lower range should give the best output.

The Enhance Sharpness slider allows you to sharpen images that become blurry after denoising. If you’re looking to add back specific details in your image that may have been removed by denoising, you can try the Restore Detail slider to use alpha-mask blending to restore and improve details.

 

 

Where does DeNoise AI fall the best in my workflow?

We recommend using DeNoise AI at the beginning of your workflow. Eliminating noise as a first step is key because it will ensure that you are working on a clean image! It is always important to remove any damaging defects before applying any color, detail or creative adjustments to your images.
