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.

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.

Resizing in Photoshop (Click to view at 100%)

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.

Adjustment Overview

The Basic Adjustment

The Basic Adjustment might look intimidating because there’s a lot going on but it’s very simple to use! The Basic Adjustment features Integrated Masking, Blending Modes, an Opacity Slider, Adjustment Level Presets, and sliders. The sliders are Exposure, Clarity, Shadow, and Highlight. There’s also Saturation, Temperature, and Tint. Usually, sliding to the left is “less” while sliding to the right is “more”. I’ll be going into each slider’s function in depth so read on to learn more!

Adjustment Level Presets

Every Adjustment in Topaz Studio has Adjustment Level Presets. These Presets are a great place to start when editing an image. You can see each slider change when you roll over a different Preset. To commit a Preset, simply Click the Preset Name that you like.

Try it Out: Click on the Adjustment Level Presets and see how they affect your image! Once you see how the Presets change your image, Reset the Adjustment. To completely Reset your image, which deletes all Adjustments used, click Reset in the bottom right corner of the program.

Make Custom Changes

The Topaz Studio Basic Adjustment is a great starting point to adjust and correct image tone and color. Postproduction is made easy with 4 exposure related value sliders and 3 color effect related sliders. Making custom changes to any Adjustment is fast and easy. Simply click and drag a slider to make a change.

Let’s take an in depth look at what the sliders do in the Basic Adjustment. Now that you know how to Reset your image (remember, bottom right hand corner!) you can make changes without any fear of commitment. You can also use the Undo/Redo buttons in the bottom right of the program.

Exposure Related Sliders

Exposure Slider

Change Exposure in the Basic Adjustment

You can easily update the overall exposure of the image by adjusting the Exposure slider. Simply increase the value of the Exposure slider and the image will become lighter. By decreasing the value, the overall image will become darker. No matter what you do, you’ll never lose color or image integrity, even with extreme adjustments.

Try it Out: Click on the handle (the white dot) and slide it around to see how your image is affected. You can also manually type in values from -1.00 to 1.00, use your arrow key to change the value .01 at a time, or click on the slider to move the handle there instantly. To reset the slider, put it on 0.00. You can also click the Slider Title to reset it.

Clarity Slider

Change Clarity in Basic Adjustment

The Clarity Slider is one of my personal favorites! You can make your image soft and smooth or detailed or even HDR-like! Clarity’s microcontrast technology emulates a skilled retoucher’s method of selectively brightening and darkening parts of your image. Bring out details in images by increasing the value of the slider. To soften image details simply decrease the Clarity slider.

Try it Out: Move the handle all the way to -1.00 to see how smooth and clean your image can look. Then, move the slider to 1.00 and you’ll see how detailed your image can become.

Shadow Slider

Change Shadow in Topaz Studio

Selectively manipulate shadows and dark tones within any image with the Shadow slider. Lighten all the shadows within an image by increasing the value of the slider or darken shadows and lowlights by decreasing the value. Any adjustment made will only affect the darker image tones and shadows.

Try it Out: Click on the handle (the white dot) and slide it around to see how your image is affected. You’ll notice that the dark areas of the image change. Try out a couple different settings and see which one you like best!

Highlight Slider

Change Highlight in Topaz Studio

The highlights in the image are where the image has whites or very light areas. You can effortlessly control image highlights within any image with the Highlight slider. Lighten all the highlights within an image by decreasing the value of the slider or increase the brightness of highlights by increasing the value. The adjustment will selectively affect the lightest areas of the image.

Try it Out: Click on the handle (the white dot) and slide it towards the right. See how bright your image becomes in specific areas? This is where your highlights are and they are changing because of the Highlight Slider changes! If you slide the Handle to the left the image highlights will become darker. Change around the slider to see how your image is affected. You can also manually type in values from -1.00 to 1.00, use your arrow key to change the value .01 at a time, or click on the slider to move the handle there instantly.

Color Related Sliders

Saturation Slider

Change Saturation in Basic Adjustment

The Saturation slider in the Basic Adjustment is one of my favorite sliders! It easily adds and removes color from images. Increase or decrease overall image saturation by changing the value of the slider.

Try it Out: Click on the handle and slide it around to see how your image is affected. Try desaturating your image by sliding all the way to the left and trying oversaturating your image by going all the way to the right.

Temperature Slider

Change Temperature in Basic Adjustment

The Temperature slider allows you to effortlessly make images warmer or cooler. Increase the slider to add more yellow to warm up an image or decrease the slider to add more blue to make an image appear cooler.

Try it Out: Use the handle to change the Temperature. The slider is more blue to the left (-1.00) and more yellow to the right (1.00). This comes in handy if you have a color cast from shade or sunlight.

Tint Slider

Change Tint in the Basic Adjustment

Update an image’s overall color cast with the Tint slider. Decreasing the tint value will increase the green tint to an image while increasing the value will create a magenta tint.

Try it Out: Use the handle to change the Tint. The slider is more green to the left (-1.00) and more magenta to the right (1.00). This slider is great for balancing colors.

Adjustment Level Tools

Every Adjustment has tools. You’ll find adjustment level masking, an opacity slider, 28 blending modes, and more in the adjustment header. You can also turn the adjustment on and off, use advanced tools in the menu, and delete the adjustment.

Adjustment level tools make it easy to customize the Adjustment.

1. Masking. You can mask out (or in) pieces of your Adjustment with the Adjustment Level Masking Tool. There are 5 options including Spot, Brush, Gradient, Color, and Luminosity. You can invert the mask, make adjustments to it, stack different types, and much more!

2. Disable Adjustment. Turn the Adjustment on and off.

3. Menu. The Menu allows you to Copy, Paste, and Duplicate Adjustments. You can also Copy and Paste Masks or head over to the webpage by selecting Learn More…

4. Delete. Use the trashcan icon to delete the Adjustment.

5. Opacity. Use the Opacity slider to make the Adjustment lighter or stronger.

6. Blending Mode. Choose a Blending Mode to blend an Adjustment with only parts of your image.

Give these a try and see what they do! You can always use the Undo and Redo buttons in the bottom right hand side of the program. Topaz Studio features unlimited Undo / Redo so experiment as much as you like!

That’s It!

And that’s everything you can accomplish with the Basic Adjustment in Topaz Studio and how you can do it! I hope you tried out a few new things today and learned a little about the endless possibilities within Topaz Studio.
